hierarchical grid, access to parent column by index

[Jean-Marc]

I have a hierarchical grid. To fill the child grid I need to know a parent ID value.
Can not access to that with GetDataKeyValue because parent grid is autogenerate.

So how can access to the parent grid by column index?

Protected Sub RadGrid1_DetailTableDataBind(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridDetailTableDataBindEventArgs) Handles RadGrid1.DetailTableDataBind

Dim dataItem As GridDataItem = CType(e.DetailTableView.ParentItem, GridDataItem)
Dim ID As String = dataItem.Item(?).Text

Thank you

Hello Jean,

You can try the following code snippet to access DataKeyValue.

aspx:

<telerik:RadGrid runat="server" ID="RadGrid2" AutoGenerateColumns="true">
  <MasterTableView DataKeyNames="ID">
      . . .
  </MasterTableView>
</telerik:RadGrid>

VB:

Protected Sub RadGrid2_DetailTableDataBind(sender As Object, e As GridDetailTableDataBindEventArgs)
    If e.DetailTableView.Name = "DetailTable1" Then
        Dim detailtabl1 As GridTableView = DirectCast(e.DetailTableView, GridTableView)
        Dim parentItem As GridDataItem = DirectCast(detailtabl1.ParentItem, GridDataItem)
        Dim Id As String = parentItem.GetDataKeyValue("ID").ToString()
    End If
End Sub

Thanks,
Princy.
