New MyEditTemplate(templateColumnName)

 

templateColumn.EditItemTemplate =

 

New MyEditTemplate(templateColumnName)

 

templateColumn.HeaderText = tblLastItem.Rows(i)(

 

"CntrGnlItm_ParentTitr").ToString.Trim + "--" + tblLastItem.Rows(i)("CntrLstItm_Titr").ToString.Trim

Hello Salman,

In order to access the RadNumericTextBox inside template column, you should hook the Item_DataBound event of RadGrid and in its body to check for the appropriate type of item. After this condition is satisfied you should proceed by casting the item to the this type. Next  use FindControl method to find the needed control based on its server ID, after that you could get the value.

The following code snippet shows one way for achieving this:

Protected Sub RadGrid1_ItemDataBound(sender As Object, e As GridItemEventArgs) Handles RadGrid1.ItemDataBound
    If TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode Then
        Dim item As GridEditableItem = TryCast(e.Item, GridEditableItem)
        Dim radNumericTextBox As RadNumericTextBox = TryCast(item("CntrLstItm_ID_").FindControl("RadNumericTextBox_ID"), RadNumericTextBox)
        Dim value As System.Nullable(Of Double) = radNumericTextBox.Value
    End If
End Sub
