Pivot Field List in ASP.NET CORE Pivot Table Component

30 Jun 202324 minutes to read

The pivot table provides a built-in Field List similar to Microsoft Excel. It allows to add or remove fields and also rearrange them between different axes, including column, row, value, and filter along with sort and filter options dynamically at runtime.

The field list can be displayed in two different formats to interact with pivot table. They are:

• In-built Field List (Popup): To display the field list icon in pivot table UI to invoke the built-in dialog.
• Stand-alone Field List (Fixed): To display the field list in a static position within a web page.

In-built Field List (Popup)

To enable the field list in pivot table UI, set the showFieldList property in ejs-pivotview tag to true. A small icon will appear on the top left corner of the pivot table and clicking on this icon, field list dialog will appear.

NOTE

The field list icon will be displayed at the top right corner of the pivot table, when grouping bar is enabled.

Stand-alone Field List (Fixed)

The field list can be rendered in a static position, anywhere in web page layout, like a separate component. To do so, you need to set renderMode property to Fixed in ejs-pivotfieldlist.

NOTE

To make field list interact with pivot table, you need to use the UpdateView and Update methods for data source update in both field list and pivot table simultaneously.

CSHTML

<script>
    var pivotObj; var fieldlistObj;
    function onGridEnginePopulate(args) {
        pivotObj = document.getElementById('PivotView').ej2_instances[0];
        fieldlistObj = document.getElementById('PivotFieldList').ej2_instances[0];
        if (fieldlistObj) {

    }
</script>

Static.cs

public ActionResult Index()
{
    var data = GetPivotData();
    ViewBag.DataSource = data;
    return View();
}

Invoking dynamic Field List (Customized)

Also, you can display the field list dialog independently through other means. For example, you can invoke the field list dialog on an external button click. To do so, set renderMode property to Popup and since on button click, field list dialog will be invoked.

NOTE

• Meanwhile, you can display the field list dialog at specific target element within a webpage using target property. By default, the target value is null, which refers the document.body element.
  
  * Moreover, to make field list interact with pivot table, you need to use the updateView and update methods for data source update in both field list and pivot table simultaneously.

The below sample code illustrates the field list dialog invoked on an external button click.

Search desired field

End user can search for desired field in the field list UI by typing the field name into the search box at runtime. It can be enabled by setting the enableFieldSearching property to true via code-behind.

NOTE

By default, field search option is disabled in the field list UI.

To enable search box in the static field list UI, set the enableFieldSearching property to true in ejs-pivotfieldlist.

Option to sort fields

End user can sort fields in the field list UI to ascending (or) descending (or) default order (as obtained from the data source) using the built-in sort icons.

By default, fields are displayed in the default order.

Sort fields in a desired order

To display the fields in descending order by default, set the defaultFieldListOrder property to Descending in the load event.

NOTE

You can only group fields to one level using the groupName property.

Add or remove fields

Using check box besides each field, end user can select or unselect to add or remove fields respectively from the report at runtime.

Remove specific field(s) from displaying

When a data source is bound to the component, fields will be automatically populated inside the Field List. In such case, user can also restrict specific field(s) from displaying. To do so, set the appropriate field name(s) in excludeFields property belonging to e-datasourcesettings tag.

CSHTML

{
    var data = GetPivotData();
    ViewBag.DataSource = data;
    ViewBag.Excludefields = new string[] { "Products", "Amount" };
    return View();
}

Re-arranging fields

In-order to re-arrange, drag any field from the field list and drop it into the column, row, value, or filter axis using the drag-and-drop holder. It helps end user to alter the report at runtime.

Filtering members

Using the filter icon besides each field in row, column and filter axes, members can be either included or excluded at runtime. To know more about member filtering, refer here.

Sorting members

Using the sort icon besides each field in row and column axes, members can be arranged either in ascending or descending order at runtime. To know more about member sorting, refer here.

Calculated fields

The calculated field support allows end user to add a new calculated field based on the available fields from the bound data source using basic arithmetic operators. To enable this support in Field List UI, set the allowCalculatedField property in ejs-pivotview tag to true in pivot table. Now a button will be seen automatically inside the field list UI which will invoke the calculated field dialog on click. To know more about calculated field, refer here.

Changing aggregation type of value fields at runtime

End user can perform calculations over a group of values using the aggregation option. The value fields bound to the field list, appears with a dropdown icon, helps to select an appropriate aggregation type at runtime. On selection, the values in the Pivot Table will be changed dynamically. To know more about aggregation, refer here.

Defer layout update

Defer layout update support to update the pivot table only on demand and not during every user action. To enable this support in Field List UI, set the allowDeferLayoutUpdate property in ejs-pivotview tag to true in pivot table. Now a check box inside Field List UI will be seen in checked state, allowing pivot table to update only on demand. To know more about defer layout, refer here.

Show built-in Field List (Popup) over specific target

By passing the target element to the built-in field list dialog module in the dataBound event, the field list dialog will be displayed over the appropriate target element on a web page. By default, the Pivot Table’s parent element is used as the target element to display the built-in field list dialog.

The sample code below shows the built-in field list dialog using document.body as the target element.

Show field list using toolbar

It can also be viewed in toolbar by setting showFieldList and showToolbar properties in ejs-pivotview tag to true. Also, include the item FieldList within the toolbar property in ejs-pivotview tag. When toolbar is enabled, field list icon will be automatically added into the toolbar and the icon won’t appear on top left corner in the pivot table component.

Set caption to fields which isn’t bound to the report

One can set the caption to all fields from the data source even if it is not bound to the actual report. It can be achieved using the enginePopulated event. On doing so, caption of the respective field will be displayed in both grouping bar and field list.

In the sample, we have set caption to the fields Year and Quarter dynamically.

Show values button

During runtime, the Values button in the field list can be moved to a different position (i.e., different index) among other fields in the column or row axis. To enable the Values button, set the showValuesButton property to true.

NOTE

This support is only available for relational data sources.

Events

EnginePopulated

The enginePopulated event is available in both Pivot Table and Field List.

• The event enginePopulated is triggered in field list whenever the report gets modified. The updated report is passed to the pivot table via updateView method written within this event to refresh the same.

• Likewise, enginePopulated event is triggered in pivot table whenever the report gets modified. The updated report is passed to the field list via update method written within this event to refresh the same.

The event enginePopulated is triggered after engine is populated. It has following parameters - dataSourceSettings, pivotFieldList and pivotValues.

NOTE

This event is not required for Popup field list since it is a in built one.
