Tool bar in EJ2 JavaScript Pivotview control
8 Aug 202324 minutes to read
Toolbar option allows to access the frequently used features like switching between pivot table and pivot chart, changing chart types, conditional formatting, exporting, etc… with ease at runtime. This option can be enabled by setting the showToolbar property in pivot table to true. The toolbar property in pivot table accepts the collection of built-in toolbar options.
Built-in Toolbar Options
The following table shows built-in toolbar options and its actions.
| Built-in Toolbar Options | Actions |
|---|---|
| New | Creates a new report |
| Save | Saves the current report |
| Save As | Save as current report |
| Rename | Renames the current report |
| Delete | Deletes the current report |
| Load | Loads any report from the report list |
| Grid | Shows pivot table |
| Chart | Shows a chart in any type from the built-in list and option to enable/disable multiple axes |
| Exporting | Exports the pivot table as PDF/Excel/CSV and the pivot chart as PDF and image |
| Sub-total | Shows or hides sub totals |
| Grand Total | Shows or hides grand totals |
| Conditional Formatting | Shows the conditional formatting pop-up to apply formatting |
| Number Formatting | Shows the number formatting pop-up to apply number formatting |
| Field List | Shows the fieldlist pop-up |
| MDX | Shows the MDX query that was run to retrieve data from the OLAP data source. NOTE: This applies only to the OLAP data source. |
The order of toolbar options can be changed by simply moving the position of items in the toolbar collection. Also if end user wants to remove any toolbar option from getting displayed, it can be simply ignored from adding into the toolbar collection.

</html>Switch the chart to multiple axes
In the chart, the user can switch from single axis to multiple axes with the help of the built-in checkbox available inside the chart type dropdown menu in the toolbar. For more information refer here.
There are three modes available in Multiple Axis option: Stacked, Single and Combined. The modes can be changed using “Multiple Axis Mode” drop-down list which appears while clicking the More… option.
Show or hide legend
In the chart, legend can be shown or hidden dynamically with the help of the built-in option available in the chart type drop-down menu.
By default, the legend is not be visible for the accumulation chart types like pie, doughnut, pyramid, and funnel. Users can enable or disable using the built-in checkbox option.
Adding custom option to the toolbar
In addition to the existing built-in toolbar items, new toolbar item(s) may also be included. This can be achieved by using the toolbarRender event. The action of the new toolbar item(s) can also be defined within this event.
The new toolbar item(s) can be added to the desired position in the toolbar using the
spliceoption.

</html>In the above topic, we have seen how to add an icon as one of the toolbar item in toolbar panel. In the next topic, we are going to see how to frame the entire toolbar panel and how to add a custom control in it.
Toolbar Template
It allows to customize the toolbar panel by using template option. It allows any custom control to be used as one of the toolbar item inside the toolbar panel. It can be achieved by two ways,
Here, the entire toolbar panel can be framed in HTML elements that are appended at the top of the pivot table. The id of the HTML element needs to be set in the toolbarTemplate property in-order to map it to the pivot table.
var pivotTableObj = new ej.pivotview.PivotView({
dataSourceSettings: {
dataSource: pivotData,
expandAll: true,
columns: [{ name: 'Year', caption: 'Production Year' }, { name: 'Quarter' }],
values: [{ name: 'Sold', caption: 'Units Sold' }, { name: 'Amount', caption: 'Sold Amount' }],
rows: [{ name: 'Country' }, { name: 'Products' }],
filters: [],
},
toolbarTemplate:'#template',
showToolbar:true,
height: 350,
});
pivotTableObj.appendTo('#PivotTable');
var btnExpand = new ej.buttons.Button({ content: 'Expand All', cssClass: "e-primary" });
btnExpand.appendTo('#btnexpand');
var btnCollapse = new ej.buttons.Button({ content: 'Collapse All', cssClass: "e-primary" });
btnCollapse.appendTo('#btncollapse');
document.getElementById('btnexpand').onclick = function () {
pivotTableObj.dataSourceSettings.expandAll = true;
};
document.getElementById('btncollapse').onclick = function () {
pivotTableObj.dataSourceSettings.expandAll = false;

SQL Server is a relational database management system (RDBMS) that can be used to store and manage large amounts of data. In this topic, we will see how to save, save as, rename, load, delete, and add reports between a SQL Server database and a JavaScript Pivot Table at runtime.
Create a Web API service to connect to a SQL Server database
1. Open Visual Studio and create an ASP.NET Core Web App project type, naming it MyWebService. To create an ASP.NET Core Web application, follow the document link.
2. To connect a SQL Server database using the Microsoft SqlClient in our application, we need to install the Microsoft.Data.SqlClient NuGet package. To do so, open the NuGet package manager of the project solution, search for the package Microsoft.Data.SqlClient and install it.
3. Under the Controllers folder, create a Web API controller (aka, PivotController.cs) file that aids in data communication with the Pivot Table.
4. In the Web API Controller (aka, PivotController), the OpenConnection method is used to connect to the SQL database. The GetDataTable method then processes the specified SQL query string, retrieves data from the database, and converts it into a DataTable using SqlCommand and SqlDataAdapter. This DataTable can be used to retrieve saved reports and modify them further as shown in the code block below.
[PivotController.cs]
using Microsoft.AspNetCore.Mvc;

sqlConn.Close();
}
private SqlConnection OpenConnection()
{
// Replace with your own connection string.
string connectionString = @"<Enter your valid connection string here>";
SqlConnection sqlConn = new SqlConnection(connectionString);
sqlConn.Open();
return sqlConn;
}
private DataTable GetDataTable(SqlConnection sqlConn)
{
string xquery = "SELECT * FROM ReportTable";
SqlCommand cmd = new SqlCommand(xquery, sqlConn);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);
return dt;
}
}
}5. When you run the app, it will be hosted at https://localhost:44313. You can use the hosted URL to save and load reports in the SQL database from the Pivot Table.
Further, let us explore more on how to save, load, rename, delete, and add reports using the built-in toolbar options via Web API controller (aka, PivotController) one-by-one.
Saving a report
When you select the “Save a report” option from the toolbar, the saveReport event is triggered. In this event, an AJAX request is made to the Web API controller’s SaveReport method, passing the name of the current report and the current report, which you can use to check and save in the SQL database.
For example, the report shown in the following code snippet will be passed to the SaveReport method along with the report name “Sample Report” and saved in the SQL database.
[index.js]
var pivotTableObj = new ej.pivotview.PivotView({
dataSourceSettings: {
columns: [
{ name: "Year", caption: "Production Year" },
{ name: "Quarter" },
],
dataSource: getPivotData(),
expandAll: false,
filters: [],
formatSettings: [{ name: "Amount", format: "C0" }],
rows: [{ name: "Country" }, { name: "Products" }],
values: [
{ name: "Sold", caption: "Units Sold" },
{ name: "Amount", caption: "Sold Amount" },
],
},
height: 350,
saveReport: function (args) {
var report = JSON.parse(args.report);
report.dataSourceSettings.dataSource = [];
fetch("https://localhost:44313/Pivot/SaveReport", {
method: "POST",
headers: {
Accept: "application/json",
"Content-Type": "application/json",
},
body: JSON.stringify({
reportName: args.reportName,
report: JSON.stringify(report),
}),
})
.then(function (response) {
pivotTableObj.fetchReport();
});
},
toolbar: ['New', 'Save', 'SaveAs', 'Rename', 'Remove', 'Load',
'Grid', 'Chart', 'Export', 'SubTotal', 'GrandTotal', 'ConditionalFormatting', 'FieldList'],
allowExcelExport: true,
allowConditionalFormatting: true,
allowPdfExport: true,
showToolbar: true,
allowCalculatedField: true,
displayOption: { view: "Both" },
showFieldList: true,
height: "700",
});
pivotTableObj.appendTo("#PivotView");[PivotController.cs]
namespace MyWebApp.Controllers
{
[ApiController]
[Route("[controller]")]
public class PivotController : ControllerBase
{
[HttpPost]
[Route("Pivot/SaveReport")]
public void SaveReport(Dictionary<string,string> args)
{
SaveReportToDB(args["ReportName"], args["Report"]);
}
public void SaveReportToDB(string reportName, string report)
{
SqlConnection sqlConn = OpenConnection();
bool isDuplicate = true;
SqlCommand cmd1 = null;
foreach (DataRow row in GetDataTable(sqlConn).Rows)
{
if ((row["ReportName"] as string).Equals(reportName))
{
isDuplicate = false;
cmd1 = new SqlCommand("UPDATE ReportTable set Report=@Report where ReportName like @ReportName", sqlConn);
}
}
if (isDuplicate)
{
cmd1 = new SqlCommand("INSERT into ReportTable (ReportName,Report) Values(@ReportName,@Report)", sqlConn);
}
cmd1.Parameters.AddWithValue("@ReportName", reportName);
cmd1.Parameters.AddWithValue("@Report", report.ToString());
cmd1.ExecuteNonQuery();
sqlConn.Close();
}
private SqlConnection OpenConnection()
{
// Replace with your own connection string.
string connectionString = @"<Enter your valid connection string here>";
SqlConnection sqlConn = new SqlConnection(connectionString);
sqlConn.Open();
return sqlConn;
}
private DataTable GetDataTable(SqlConnection sqlConn)
{
string xquery = "SELECT * FROM ReportTable";
SqlCommand cmd = new SqlCommand(xquery, sqlConn);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);
return dt;
}
}
}
In the meantime, you can save a duplicate of the current report to the SQL Server database with a different name by selecting “Save as current report” from the toolbar. The saveReport event will then be triggered with the new report name “Sample Report 1” and the current report. You can save them to the SQL Server database after passing them to the Web API service, as mentioned above.
Loading a report
When you select the dropdown menu item from the toolbar, the loadReport event is triggered. In this event, an AJAX request is made to the LoadReport method of the Web API controller, passing the name of the selected report. The method uses this information to search for the report in the SQL database, fetch it, and load it into the pivot table.
For example, if the report name “Sample Report 1” is selected from a dropdown menu and passed, the LoadReport method will use that name to search for the report in the SQL database, retrieve it, and then load it into the pivot table.
[index.js]
var pivotTableObj = new ej.pivotview.PivotView({
dataSourceSettings: {
columns: [
{ name: "Year", caption: "Production Year" },
{ name: "Quarter" },
],
dataSource: getPivotData(),
expandAll: false,
filters: [],
formatSettings: [{ name: "Amount", format: "C0" }],
rows: [{ name: "Country" }, { name: "Products" }],
values: [
{ name: "Sold", caption: "Units Sold" },
{ name: "Amount", caption: "Sold Amount" },
],
},
height: 350,
loadReport: function (args) {
fetch("https://localhost:44313/Pivot/LoadReport", {
method: "POST",
headers: {
Accept: "application/json",
"Content-Type": "application/json",
},
body: JSON.stringify({ reportName: args.reportName }),
})
.then(function (res) {
return res.json();
})
.then(function (response) {
if (response) {
var report = JSON.parse(response);
report.dataSourceSettings.dataSource =
pivotTableObj.dataSourceSettings.dataSource;
pivotTableObj.dataSourceSettings = report.dataSourceSettings;
}
});
},
toolbar: ['New', 'Save', 'SaveAs', 'Rename', 'Remove', 'Load',
'Grid', 'Chart', 'Export', 'SubTotal', 'GrandTotal', 'ConditionalFormatting', 'FieldList'],
allowExcelExport: true,
allowConditionalFormatting: true,
allowPdfExport: true,
showToolbar: true,
allowCalculatedField: true,
displayOption: { view: "Both" },
showFieldList: true,
height: "700",
});
pivotTableObj.appendTo("#PivotView");[PivotController.cs]
using Microsoft.AspNetCore.Mvc;
using Microsoft.Data.SqlClient;
using System.Data;
namespace MyWebApp.Controllers
{
[ApiController]
[Route("[controller]")]
public class PivotController : ControllerBase
{
[HttpPost]
[Route("Pivot/LoadReport")]
public string LoadReport(Dictionary<string, string> args)
{
return LoadReportFromDB(args["ReportName"]);
}
public string LoadReportFromDB(string reportName)
{
SqlConnection sqlConn = OpenConnection();
string report = string.Empty;
foreach (DataRow row in GetDataTable(sqlConn).Rows)
{
if ((row["ReportName"] as string).Equals(reportName))
{
report = (string)row["Report"];
break;
}
}
sqlConn.Close();
return report;
}
private SqlConnection OpenConnection()
{
// Replace with your own connection string.
string connectionString = @"<Enter your valid connection string here>";
SqlConnection sqlConn = new SqlConnection(connectionString);
sqlConn.Open();
return sqlConn;
}
private DataTable GetDataTable(SqlConnection sqlConn)
{
string xquery = "SELECT * FROM ReportTable";
SqlCommand cmd = new SqlCommand(xquery, sqlConn);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);
return dt;
}
}
}
Renaming a report
When you select the “Rename a current report” option from the toolbar, the renameReport event is triggered. In this event, an AJAX request is made to the RenameReport method of the Web API controller, passing the current and new report names, where you can use the current report name to identify the report and resave it with the new report name in the SQL database.
For example, if we rename the current report from “Sample Report 1” to “Sample Report 2”, both “Sample Report 1” and “Sample Report 2” will be passed to the RenameReport method, which will rename the current report with the new report name “Sample Report 2” in the SQL database.
[index.js]
var pivotTableObj = new ej.pivotview.PivotView({
dataSourceSettings: {
columns: [
{ name: "Year", caption: "Production Year" },
{ name: "Quarter" },
],
dataSource: getPivotData(),
expandAll: false,
filters: [],
formatSettings: [{ name: "Amount", format: "C0" }],
rows: [{ name: "Country" }, { name: "Products" }],
values: [
{ name: "Sold", caption: "Units Sold" },
{ name: "Amount", caption: "Sold Amount" },
],
},
height: 350,
renameReport: function (args) {
fetch("https://localhost:44313/Pivot/RenameReport", {
method: "POST",
headers: {
Accept: "application/json",
"Content-Type": "application/json",
},
body: JSON.stringify({
reportName: args.reportName,
renameReport: args.rename,
isReportExists: args.isReportExists
}),
})
.then(function (response) {
pivotTableObj.fetchReport();
});
},
toolbar: ['New', 'Save', 'SaveAs', 'Rename', 'Remove', 'Load',
'Grid', 'Chart', 'Export', 'SubTotal', 'GrandTotal', 'ConditionalFormatting', 'FieldList'],
allowExcelExport: true,
allowConditionalFormatting: true,
allowPdfExport: true,
showToolbar: true,
allowCalculatedField: true,
displayOption: { view: "Both" },
showFieldList: true,
height: "700",
});
pivotTableObj.appendTo("#PivotView");[PivotController.cs]
using Microsoft.AspNetCore.Mvc;
using Microsoft.Data.SqlClient;
using System.Data;
namespace MyWebApp.Controllers
{
[ApiController]
[Route("[controller]")]
public class PivotController : ControllerBase
{
[HttpPost]
[Route("Pivot/RenameReport")]
public void RenameReport(Dictionary<string, string, bool> args)
{
RenameReportInDB(args["ReportName"], args["Rename"], args["isReportExists"]);
}
public void RenameReportInDB(string reportName, string renameReport, bool isReportExists)
{
SqlConnection sqlConn = OpenConnection();
SqlCommand cmd1 = null;
if (isReportExists)
{
RemoveReportFromDB(renameReport);
}
foreach (DataRow row in GetDataTable(sqlConn).Rows)
{
if ((row["ReportName"] as string).Equals(reportName))
{
cmd1 = new SqlCommand("UPDATE ReportTable set ReportName=@RenameReport where ReportName like '%" + reportName + "%'", sqlConn);
break;
}
}
cmd1.Parameters.AddWithValue("@RenameReport", renameReport);
cmd1.ExecuteNonQuery();
sqlConn.Close();
}
private SqlConnection OpenConnection()
{
// Replace with your own connection string.
string connectionString = @"<Enter your valid connection string here>";
SqlConnection sqlConn = new SqlConnection(connectionString);
sqlConn.Open();
return sqlConn;
}
private DataTable GetDataTable(SqlConnection sqlConn)
{
string xquery = "SELECT * FROM ReportTable";
SqlCommand cmd = new SqlCommand(xquery, sqlConn);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);
return dt;
}
}
}
Deleting a report
When you select the “Delete a current report” option from the toolbar, the removeReport event is triggered. In this event, an AJAX request is made to the RemoveReport method of the Web API controller, passing the current report name to identify and delete the appropriate report from the SQL database.
- If the current report n from the pivot table is deleted, the pivot table will automatically load the last report from the report list.
- When a report is removed from a pivot table with only one report, the SQL database refreshes; however, the pivot table will continue to show the removed report until a new report is added to the pivot table.
For example, if we delete the current report “Sample Report 2” from the pivot table, the current report name “Sample Report 2” is passed to the RemoveReport method, which allows you to identify and delete the report from the SQL database.
[index.js]
var pivotTableObj = new ej.pivotview.PivotView({
dataSourceSettings: {
columns: [
{ name: "Year", caption: "Production Year" },
{ name: "Quarter" },
],

],
},
height: 350,
removeReport: function (args) {
fetch("https://localhost:44313/Pivot/RemoveReport", {
method: "POST",
headers: {
Accept: "application/json",
"Content-Type": "application/json",
},
body: JSON.stringify({ reportName: args.reportName }),
})
.then(function (response) {
pivotTableObj.fetchReport();
});

break;
}
}

}
private SqlConnection OpenConnection()
{
// Replace with your own connection string.

SqlConnection sqlConn = new SqlConnection(connectionString);
sqlConn.Open();
return sqlConn;
}
private DataTable GetDataTable(SqlConnection sqlConn)
{
string xquery = "SELECT * FROM ReportTable";
SqlCommand cmd = new SqlCommand(xquery, sqlConn);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);
return dt;
}
}
}
Adding a report
When you select the “Create a new report” option from the toolbar, the newReport event is triggered, followed by the saveReport event. To save this new report to the SQL database, use the saveReport event triggered later, and then follow the save report briefing in the preceding topic.
Limitations with respect to report manipulation
Below points need to be considered when saving the report to SQL Server database.
- Data source: Both raw data and aggregated data won’t be saved and loaded from the database.
- Conditional formatting: The appearance of the pivot table, such as background color, font color, font family, and font size based on the specific conditions won’t be saved and loaded from the database.
- Hyperlinks: Option to link external facts via pivot table cells won’t be saved and loaded from the database.
- The pivot table should always load reports from the SQL database based on the data source that is currently bound to it.
In this GitHub repository, you can find our Javascript Pivot Table sample and ASP.NET Core Web Application to save and load reports from SQL Server database.
