ASPxGridViewCustomCallbackEventArgs Class
Provides data for the ASPxGridView.CustomCallback event.
Namespace: DevExpress.Web
Assembly: DevExpress.Web.v21.1.dll
NuGet Package: DevExpress.Web
Declaration
Remarks
The ASPxGridView.CustomCallback event is raised when a round trip to the server has been initiated. This occurs when the client ASPxClientGridView.PerformCallback method is called.
The ASPxGridViewCustomCallbackEventArgs class provides the ASPxGridCustomCallbackEventArgs.Parameters property that specifies a string containing specific information passed from the client side. You can use this property to recognize different kinds of callbacks for performing various actions on the server side.
Example
protected void Grid_CustomCallback(object sender, ASPxGridViewCustomCallbackEventArgs e) {
if(e.Parameters == "ApplyCustomFilter")
Grid.FilterExpression = "City = 'Bratislava'";
if(e.Parameters == "ApplyCustomGrouping") {
Grid.DataColumns["City"].GroupBy();
Grid.ExpandAll();
}
}
