RadGrid - Unable to get insert values From Edit Form with Multiple Columns

[Hunter]

I am trying to get values when inserting from an Edit Form (with Multiple Columns) in preparation for writing a record to the database.  I'm sure it's something simple t o get this working.  However when I try to retrieve the value for a field in the InsertCommand handler it looks like the textbox can't be located.  I'm not sure what I should cast e.item to in the handler.  I've seen and tried three different types unsuccessfully: GridEditFormInsertItem, GridEditFormItem and GridEditableItem. 

<telerik:RadGrid ID="rgLocations" runat="server" Width="100%"  AutoGenerateColumns="false"

    </telerik:RadGrid>

Protected Sub rgLocations_NeedDataSource(sender As Object, e As Telerik.Web.UI.GridNeedDataSourceEventArgs)
    Dim ClientID As String = Session("ClientID")
    Dim oCLientLocations As clsClientLocations = New clsClientLocations(ClientID)
    rgLocations.DataSource = oCLientLocations.DataTable
End Sub

Protected Sub rgLocations_InsertCommand(sender As Object, e As Telerik.Web.UI.GridCommandEventArgs)
    Dim editedItem As GridEditFormItem = CType(e.Item, GridEditableItem)

    Dim LocationName As String = CType(editedItem("LocationName").FindControl(0), TextBox).Text
End Sub

 
In the ItemCOmmand handler, the LocationName does not get set.  I the error message: "Object reference not set to an instance of an object."  WHich is because editItem("LocationName").FindControl(0) is "Nothing".

Thanks in advance for any help on this.

Hello,

Protected Sub RadGrid1_InsertCommand(sender As Object, e As GridCommandEventArgs)
    Dim item As GridEditableItem = TryCast(e.Item, GridEditableItem)
    Dim str1 As String = TryCast(item("LocationName").Controls(0), TextBox).Text
End Sub

<telerik:GridBoundColumn DataField="LocationName" UniqueName="LocationName" HeaderText="LocationName">
                  </telerik:GridBoundColumn>

Thanks,
Jayesh Goyani
