Commands that invoke Rebind Implicitly

This topic lists which internal grid commands make an implicit call to the Rebind() method of RadGrid in order to refresh the control's content and fetch the latest information from the grid source.Here is the complete list of commands that trigger Rebind():

 

Command Name	Field
ExpandCollapse	RadGrid.ExpandCollapseCommandName
Update	RadGrid.UpdateCommandName
Cancel	RadGrid.CancelCommandName
Delete	RadGrid.DeleteCommandName
Edit	RadGrid.EditCommandName
InitInsert	RadGrid.InitInsertCommandName
PerformInsert	RadGrid.PerformInsertCommandName
RebindGrid	RadGrid.RebindGridCommandName
Page	RadGrid.PageCommandName
Sort	RadGrid.SortCommandName
Filter	RadGrid.FilterCommandName
Note that the following commands do not perform internal rebind:
Select	RadGrid.SelectCommandName
Deselect	RadGrid.DeselectCommandName

When RadGrid's ViewState is turned off, the NeedDataSource event does not fire after any of the above listed commands. This is so because it fires after Page_Load and the control already has a DataSource assigned when the command takes place. If you want to make the event fire in such scenarios, you need to first set RadGrid's DataSource to null/Nothing and then call Rebind().
