'This is called Event Bubbling. 'Inside the usercontrol code-behind add this ( its in
VB.NET, sorry if ur C# coder )
Public Event ImgBtnClick As EventHandler 'Event handler declaration
Protected Overridable Sub OnImgBtnClick (ByVal e As EventArgs)
RaiseEvent ImgBtnClick(Me, e)
End Sub
'Now you need to Override OnBubbleEvent
Protected Overrides Function OnBubbleEvent(ByVal source As Object, ByVal e As
EventArgs) As Boolean
Dim handled As Boolean = False
If TypeOf e Is CommandEventArgs Then
Dim ce As CommandEventArgs = CType(e, CommandEventArgs)
Select Case ce.CommandName
Case "ImageClick" 'Please don't forget to put this name inside your imagebutton
CommandName
OnImgBtnClick (ce)
handled = True
End Select
End If
Return handled
End Function'in your hosting ASPX page you can use it as follows. ( assuming ur
usercontrol name is ucontrol1 )
Public Sub UserControlImageButton_Handler(ByVal sender As Object, ByVal e As
System.EventArgs) Handles ucontrol1.ImgBtnClick
End Sub
Check my site for a complete example with grid related samples.
