Searching in Blazor DataGrid Component
29 Nov 202424 minutes to read
The Syncfusion® Blazor Grid includes a powerful built-in searching feature that allows users to search for specific data within the grid. This feature enables efficient filtering of grid records based on user-defined search criteria, making it easier to locate and display relevant information. Whether you have a large dataset or simply need to find specific records quickly, the search feature provides a convenient solution.
Set the AllowSearching property to true to enable the searching feature in the grid.
To further enhance the search functionality, you can integrate a search text box directly into the grid’s toolbar. This allows users to enter search criteria conveniently within the grid interface. To add the search item to the grid’s toolbar, use the Toolbar property and add Search item.

}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 Grid.
Initial search
By default, the search operation can be performed on the grid data after the grid renders. However, there might be scenarios where need to perform a search operation on the grid data during the initial rendering of the grid. In such cases, you can make use of the initial search feature provided by the grid.
To apply search at initial rendering, need to set the following properties in the GridSearchSettings component.
| Property | Description |
|---|---|
| Fields | Specifies the Fields in which the search operation needs to be performed. |
| Operator | Specifies the Operator to be used for the search operation. |
| Key | Specifies the key value to be searched. |
| IgnoreCase | IgnoreCase specifies whether the search operation needs to be case-sensitive or case-insensitive |
| IgnoreAccent | IgnoreAccent property will ignore the diacritic characters or accents in the text during a search operation. |
The following example demonstrates how to set an initial search in the grid using the GridSearchSettings property. The GridSearchSettings property is set with the following values:
1.Field: CustomerID specifies that the search should be performed only in the ‘CustomerID’ field.
2.Operator: contains indicates that the search should find records that contain the specified search key.
3.Key: Ha is the initial search key that will be applied when the grid is rendered.
4.IgnoreCase: true makes the search case-insensitive.
5.IgnoreAccent: true will ignores diacritic characters or accents during the search operation.

}By default, datagrid searches all the bound column values. To customize this behavior, define the
Fieldsproperty of GridSearchSettings component.
Search operators
Search operators are symbols or keywords used to define the type of comparison or condition applied during a search operation. They help specify how the search key should match the data being searched. The GridSearchSettings.Operator property can be used to define the search operator in the grid.
By default, the GridSearchSettings.Operator is set to contains, which returns the values contains the search key. The following operators are supported in 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. |
These operators provide flexibility in defining the search behavior and allow you to perform different types of comparisons based on your requirements.
The following example demonstrates how to set the SearchSettings.Operator property based on changing the dropdown value using the ValueChange event of the DropDownList component.

}Search by external button
The Syncfusion® Blazor Grid component allows you to perform searches programmatically, enabling you to search for records using an external button instead of relying solely on the built-in search bar. This feature provides flexibility and allows for custom search implementations within your application. To search for records using an external button, you can utilize the SearchAsync method provided by the Grid component.
The SearchAsync method allows you to perform a search operation based on a search key or criteria. The following example demonstatres how to implement SearchAsync by an external button using the following steps:
-
Add a Syncfusion® Blazor Button element outside of the grid component.
-
Attach a OnClick event handler to the button.
-
Inside the event handler, get the reference of the grid component.
-
Invoke the
SearchAsyncmethod of the grid by passing the search key as a parameter.

}Search specific columns
By default, the search functionality searches all visible columns. However, if you want to search only specific columns, you can define the specific column’s field names in the GridSearchSettings.Fields property. This allows you to narrow down the search to a targeted set of columns, which is particularly useful when dealing with large datasets or grids with numerous columns.
The following example demonstrates how to search specific columns such as CustomerID and ShipCity by using the SearchSettings.Fields property.
@using Syncfusion.Blazor.Grids

<GridSearchSettings Fields=@SpecificColumns></GridSearchSettings>

}Disable search for particular column
By default, DataGrid searches all visible columns. You can disable searching for a particular column by setting the AllowSearching property of GridColumn as false.
In the below code example, the Order ID column search functionality is disabled.

Search on each key stroke
The search on each keystroke feature in Syncfusion® Grid enables you to perform real-time searching of grid data as they type in the search text box. This functionality provides a seamless and interactive searching experience, allowing you to see the search results dynamically updating in real time as they enter each keystroke in the search box.
By default, the datagrid will initiate searching operation after the Enter key is pressed. If you want to initiate the searching operation while typing the values in the search box, then you can invoke the SearchAsync method of the datagrid in the Input event by rendering the SfTextBox comonent as toolbar template component.

}Perform search operation in Grid using multiple keywords
In addition to searching with a single keyword, the Grid component offers the capability to perform a search operation using multiple keywords. This feature enables you to narrow down your search results by simultaneously matching multiple keywords. It can be particularly useful when you need to find records that meet multiple search conditions simultaneously.
The following example demonstrates, how to perform a search with multiple keywords in the grid by using the query property .

}Clear search by external button
The Syncfusion® Grid component provides a capability to clear searched data in the grid. This functionality offers the ability to reset or clear any active search filters that have been applied to the grid’s data.
To clear the searched grid records from an external button, you can set the SearchSettings.Key property to an empty string to clear the search text.This property represents the current search text in the search box.
The following example demonstrates how to clear the searched records using an external button.
@using Syncfusion.Blazor.Buttons
@using Syncfusion.Blazor.Grids
<SfButton Content="ClearSearch" OnClick="clearSearch"></SfButton>
<SfGrid @ref="DefaultGrid" DataSource="@Orders" AllowSorting="true" Toolbar=@ToolbarItems>
<GridColumns>
<GridColumn Field=@nameof(OrderData.OrderID) HeaderText="Order ID" TextAlign="TextAlign.Right" Width="120"></GridColumn>
<GridColumn Field=@nameof(OrderData.CustomerID) HeaderText="Customer ID" Width="120"></GridColumn>
<GridColumn Field=@nameof(OrderData.ShipCity) HeaderText="Ship City" Width="120"></GridColumn>
<GridColumn Field=@nameof(OrderData.ShipName) HeaderText="Ship Name" Width="120"></GridColumn>
</GridColumns>
</SfGrid>
