#Declaration
public class ASPxGridViewCustomCallbackEventArgs :
ASPxGridCustomCallbackEventArgs
#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();
}
}
