I am trying to add a handler when the GridContainer is created.  I add the handler but the code is never called.  Does anyone know what I'm doing wrong here?  I have listed the creation of the handler and the code that should be called below:

I have the following VB .NET code when the ContainerGrid is created:

AddHandler containerGrid.PageIndexChanged, AddressOf Paging_PageIndexChanged

That handler points to this test code that is not reached:

 Private Sub Paging_PageIndexChanged(ByVal sender As Object, ByVal e As Infragistics.Web.UI.GridControls.PagingEventArgs)

        Dim test As Integer = 0

End Sub

Hi tkthatikonda,

The sender is actually a ContainerGrid because the paging happens on a grid by grid basis.  It doesn't matter whether it is the root level or a child.  The sender will not be a WHDG for this event.

-dave

int currentIndexPage =  ((WebHierarchicalDataGrid)sender).Behaviors.Paging.PageIndex;

This line does not work. It throws an error saying -

Cannot cast 'sender' (which has an actual type of 'Infragistics.Web.UI.GridControls.ContainerGrid') to 'Infragistics.Web.UI.GridControls.WebHierarchicalDataGrid' Infragistics.Web.UI.GridControls.WebHierarchicalDataGrid

I have replaced the line with -

int currentIndexPage =  ((ContainerGrid)sender).Behaviors.Paging.PageIndex;

Hi,

If i am using this manul load on demand child level paging, i am getting error:  "Microsoft JScript runtime error: 'Sys.Res.argumentDomElement' is null or not an object"

public void Paging_PageIndexChanged(object sender, PagingEventArgs e)
{

int oldPageIndex = e.OldPageIndex;

int currentIndexPage = ((ContainerGrid)sender).Behaviors.Paging.PageIndex;

}

Do you have any idea!

Warm & Best Regards,
