Searching in EJ2 JavaScript Grid control
13 Apr 202324 minutes to read
You can search records in a Grid, by using the search
method with search key as a parameter. This also provides an option to integrate search text box in grid’s toolbar by adding search
item to the toolbar
.
To search records, inject the Search
module in the grid.
The clear icon is shown in the Data Grid search text box when it is focused on search text or after typing the single character in the search text box. A single click of the clear icon clears the text in the search box as well as the search results in the Data Grid.
ej.grids.Grid.Inject(ej.grids.Toolbar);
var grid = new ej.grids.Grid({
dataSource: data,
toolbar: ['Search'],
columns: [
{ field: 'OrderID', headerText: 'Order ID', textAlign: 'Right', width: 120, type: 'number' },
{ field: 'CustomerID', width: 150, headerText: 'Customer ID', type: 'string' },
{ field: 'Freight', headerText: 'Freight', textAlign: 'Right', width: 120, format: 'C' },
{ field: 'OrderDate', headerText: 'Order Date', textAlign: 'Right', width: 140, format: 'yMd' }
],
height: 272
});
grid.appendTo('#Grid');

Initial search
To apply search at initial rendering, set the fields, operator, key, and ignoreCase in the searchSettings
.
ej.grids.Grid.Inject(ej.grids.Toolbar);
var grid = new ej.grids.Grid({
dataSource: data,
toolbar: ['Search'],
searchSettings: { fields: ['CustomerID'], operator: 'contains', key: 'Ha', ignoreCase: true },
columns: [
{ field: 'OrderID', headerText: 'Order ID', textAlign: 'Right', width: 120 },
{ field: 'CustomerID', headerText: 'Customer ID', width: 150 },
{ field: 'ShipCity', headerText: 'Ship City', width: 150 },
{ field: 'ShipName', headerText: 'Ship Name', width: 150 }
],
height: 272
});
grid.appendTo('#Grid');

By default, grid searches all the bound column values. To customize this behavior define the
searchSettings.fields
property.
Search operators
The search operator can be defined in the searchSettings.operator
property to configure specific searching.
The following operators are supported in searching:
Operator | Description |
---|---|
startsWith | Checks whether a value begins with the specified value. |
endsWith | Checks whether a value ends with the specified value. |
contains | Checks whether a value contains the specified value. |
equal | Checks whether a value is equal to the specified value. |
notEqual | Checks for values not equal to the specified value. |
By default, the
searchSettings.operator
value iscontains
.
Search by external button
To search grid records from an external button, invoke the search
method.
var grid = new ej.grids.Grid({
dataSource: data,
columns: [
{ field: 'OrderID', headerText: 'Order ID', textAlign: 'Right', width: 120 },
{ field: 'CustomerID', headerText: 'Customer ID', width: 150 },
{ field: 'ShipCity', headerText: 'Ship City', width: 150 },
{ field: 'ShipName', headerText: 'Ship Name', width: 150 }
],
height: 260
});
grid.appendTo('#Grid');
var searchBtn= new ej.buttons.Button();
searchBtn.appendTo('#search');
document.getElementById('search').addEventListener('click', function() {
var searchText = document.getElementsByClassName('searchtext')[0].value;
grid.search(searchText);
});

Search specific columns
By default, grid searches all visible columns. You can search specific columns by defining the specific column’s field names in the searchSettings.fields
property.
ej.grids.Grid.Inject(ej.grids.Toolbar);
var grid = new ej.grids.Grid({
dataSource: data,
searchSettings: { fields: ['CustomerID', 'ShipCity', 'ShipName']},
columns: [
{ field: 'OrderID', headerText: 'Order ID', textAlign: 'Right', width: 100 },
{ field: 'CustomerID', headerText: 'Customer ID', width: 120 },
{ field: 'ShipCity', headerText: 'Ship City', width: 100 },
{ field: 'ShipName', headerText: 'Ship Name', width: 100 }
],
toolbar: ['Search'],
height: 270
});
grid.appendTo('#Grid');

Clear search by external button
To clear the searched grid records from the external button, set searchSettings.key
property as empty
string.
var grid = new ej.grids.Grid({
dataSource: data,
toolbar: ['Search'],
searchSettings: { fields: ['CustomerID'], operator: 'contains', key: 'Ha', ignoreCase: true },
columns: [
{ field: 'OrderID', headerText: 'Order ID', textAlign: 'Right', width: 120 },
{ field: 'CustomerID', headerText: 'Customer ID', width: 150 },
{ field: 'ShipCity', headerText: 'Ship City', width: 150 },
{ field: 'ShipName', headerText: 'Ship Name', width: 150 }
],
height: 272
});
grid.appendTo('#Grid');
let clearBtn: Button = new Button();
clearBtn.appendTo('#clear');
document.getElementById('clear').addEventListener('click', () => {
grid.searchSettings.key='';
});

Search on each key stroke
You can search the Grid data on each key stroke by binding the keyup
event for the search input element inside the created
event. Inside the keyup
handler you can search the Grid by invoking the search
method of the Grid component.
ej.grids.Grid.Inject(ej.grids.Toolbar);
var grid = new ej.grids.Grid({
dataSource: data,
toolbar: ['Search'],
columns: [
{ field: 'OrderID', headerText: 'Order ID', textAlign: 'Right', width: 120 },
{ field: 'CustomerID', headerText: 'Customer ID', width: 150 },
{ field: 'ShipCity', headerText: 'Ship City', width: 150 },
{ field: 'ShipName', headerText: 'Ship Name', width: 150 }
],
height: 272,
created: () => {
document.getElementById(grid.element.id + "_searchbar").addEventListener('keyup', () => {
grid.search(event.target.value)
});
}
});
grid.appendTo('#Grid');

Highlight the search text
You can highlight the search text in the Grid content by adding the style inside the queryCellInfo
event. you can get the search keyword from the actionBegin
event.
ej.grids.Grid.Inject(ej.grids.Toolbar);
var key = "";
var grid = new ej.grids.Grid({
dataSource: data,
toolbar: ['Search'],
columns: [
{ field: 'OrderID', headerText: 'Order ID', textAlign: 'Right', width: 120 },
{ field: 'CustomerID', headerText: 'Customer ID', width: 150 },
{ field: 'ShipCity', headerText: 'Ship City', width: 150 },
{ field: 'ShipName', headerText: 'Ship Name', width: 150 }
],
height: 272,
actionBegin: args => {
if (args.requestType === 'searching') {
key = args.searchString.toLowerCase();
}
},
queryCellInfo: args => {
if (key != '') {
var cellContent = args.data[args.column.field];
var parsedContent = cellContent.toString().toLowerCase();
if (parsedContent.includes(key.toLowerCase())) {
var i = 0;
var searchStr = '';
while (i < key.length) {
var index = parsedContent.indexOf(key[i]);
searchStr = searchStr + cellContent.toString()[index];
i++;
}
args.cell.innerHTML = args.cell.innerText.replaceAll(
searchStr,
"<span class='customcss'>" + searchStr + '</span>'
);
}
}
}
});
grid.appendTo('#Grid');

Perform search operation in Grid using multiple keywords
You can perform a searching operation in the Grid using multiple keywords. This can be achieved by the actionBegin event of the Grid. In the following sample, we have performed the searching with multiple keywords by using the query property of grid when the requestType is searching in the actionBegin event.
ej.grids.Grid.Inject(ej.grids.Toolbar);
var values;
var key = '';
var refresh = false;
var removeQuery = false;
var valueAssign = false;
var grid = new ej.grids.Grid({
dataSource: data,
toolbar: ['Search'],
columns: [
{
field: 'OrderID',headerText: 'Order ID',textAlign: 'Center',width: 120,
},
{
field: 'CustomerID',headerText: 'Customer ID',textAlign: 'Center',width: 150,
},
{
field: 'ShipCity',headerText: 'Ship City',textAlign: 'Center',width: 150,
},
{
field: 'ShipName',headerText: 'Ship Name',textAlign: 'Center',width: 150,
},
],
searchSettings: {
fields: ['CustomerID', 'OrderID', 'ShipCity', 'ShipName'],
key: '',
},
height: 272,
actionBegin: (args) => {
if (args.requestType == 'searching') {
const keys = args.searchString.split(',');
var flag = true;
var predicate;
if (keys.length > 1) {
if (grid.searchSettings.key !== '') {
values = args.searchString;
keys.forEach((key) => {
grid.getColumns().forEach((col) => {
if (flag) {
predicate = new ej.data.Predicate(col.field,'contains',key,true);
flag = false;
}
else {
