I have a data entry form which is launched as a new RadWindow above a summary page. As users maintain their data, events are fired back to code-behind to do calcs and refresh parts of the current page/window. For example, change a quantity ordered and the current inventory available quantity refreshes from the server. This works fine.

When done, users can also click Save, the current data gets saved on the server and the window is closed. This works fine.

="myTestCss" for example,
however, the column background color never changed. It always show Officew007 backgroup color. 
The version of telerik control I am using is: RadControls for ASPNET AJAX Q1 2009
The skin of grid is: Office2007

Thanks,

Code behind:
===========

Private 

Sub grdSites_UpdateCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles grdSites.UpdateCommand

Try

Dim banquetSitId As Integer = CType(grdSites.MasterTableView.DataKeyValues(e.Item.ItemIndex).Values(0), Integer)

'Dim rdp As RadDatePicker

Dim expireDate As DateTime = Nothing

Dim isActive As Boolean

' If TypeOf (e.Item) Is GridEditFormItem Then

' Dim item As GridEditFormItem = DirectCast(e.Item, GridEditFormItem)

' If DirectCast(item.FindControl("rdpExpireDate"), Telerik.Web.UI.RadDatePicker).SelectedDate.HasValue Then

' expireDate = CType(item.FindControl("rdpExpireDate"), Telerik.Web.UI.RadDatePicker).SelectedDate.Value

' End If

'End If

If TypeOf e.Item Is GridEditFormItem AndAlso e.Item.IsInEditMode AndAlso Not e.Item.OwnerTableView.IsItemInserted Then

'Dim editItem As GridEditFormItem = DirectCast(e.Item, GridEditFormItem)

'Dim item As GridDataItem = DirectCast(editItem.ParentItem, GridDataItem)

'Dim datepick As RadDatePicker = DirectCast(editItem.FindControl("rdpExpireDate"), RadDatePicker)

Dim editedItem As GridEditableItem = DirectCast(e.Item, GridEditableItem)

Dim datepick As RadDatePicker = DirectCast(editedItem.FindControl("rdpExpireDate"), RadDatePicker)

expireDate = datepick.SelectedDate.Value

End If

If Not e.Item.FindControl("rdpExpireDate") Is Nothing Then  

If CType(e.Item.FindControl("rdpExpireDate"), Telerik.Web.UI.RadDatePicker).SelectedDate.HasValue Then

    expireDate =

CType(e.Item.FindControl("rdpExpireDate"), Telerik.Web.UI.RadDatePicker).SelectedDate.Value

End If  

End If

If Not e.Item.FindControl("chkIsActive") Is Nothing Then

    isActive = CType(e.Item.FindControl("chkIsActive"), CheckBox).Checked  

End If

BanquetController.UpdateBanquetSite(banquetSitId, expireDate, isActive)

lblMessage.Text = Localization.GetString(

"SubscribeSuccess.Text", Me.LocalResourceFile)

grdSites.EditIndexes.Clear()

BindBanquetSites()

Catch ex As Exception  

lblMessage.Text = ex.Message

End Try

End Sub


In the above code "datepick.SelectedDate.Value" returns null for me.
I have tried out a number of other combinations(currently commented out) as well, all returning null for me.

Any help would be highly appreciated.

Thanks
