[Solved] Find control on Parent Row When Expanding

[Randy]

I am trying to find a control on the parent row when expanding the grid during the ItemCommand Event.  I am unable to do so.  Can someone post a small example please?



Thanks

Hi,

Try the code snippet below to access the control in the parent item on clciking a button  in the detail table

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
    {
        if (e.CommandName == "CustomCommand")
        {
            GridDataItem dataItem = (GridDataItem)e.Item;
            GridDataItem parentItem = (GridDataItem)dataItem.OwnerTableView.ParentItem;
        }
   }

Thanks,

With the above while expaning I get the ParentItem is nothing

Here is my Code:

 

Protected Sub rgPrismQA_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles rgPrismQA.ItemCommand

 

 

Dim mecb As MutuallyExclusiveCheckBoxExtender = Nothing

 

 

 

Select Case e.CommandName

 

 

Case RadGrid.ExpandCollapseCommandName

 

 

Dim di As GridDataItem = e.Item

 

 

Dim pi As GridDataItem = di.OwnerTableView.ParentItem

 

 

 

 

 

End Select

 

 

End Sub

So here When expanding pi is nothing and I can't find the control.  Any Ideas?

Does anyone have any ideas on this?

Hi Randy,

I guess you want to access the control placed in the griditem which is expanded/collapsed. If so you can try the following code snippet.

VB:

Protected Sub RadGrid1_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs)
    Select Case e.CommandName
        Case RadGrid.ExpandCollapseCommandName
            Dim di As GridDataItem = DirectCast(e.Item, GridDataItem)
            Dim textbox1 As TextBox = DirectCast(di.FindControl("TextBox1"), TextBox)
            ' Where TextBox1 is placed in the templatecolumn of expanded/collapsed item
            Exit Select
    End Select
End Sub
