Telerik RadGrid Custom Edit Form With Date Picker

I have a custom edit form in a Telerik RadGrid where I'm trying to get the dates to bind to the RadDatePicker controls. The problem is, when I bind the date to the control, it will not allow the form to show on insert because there is no date to bind on a new insert.  I have tried binding in the code behind and also in the main page using "Container is GridEditFormInsertItem" but I keep getting "Object reference not set to an instance of an object".

Any help would be appreciated.
<telerik:RadDatePicker ID="itemLastPurchaseRadDatePicker" runat="server" Width="150px"
        Culture="en-US" DateFormat="M/d/yyyy" DisplayDateFormat="M/d/yyyy" ShowPopupOnFocus="true"
        SelectedDate='<%# ((Container is GridEditFormInsertItem) ? false : Bind ("ItemVendorLastPriceDate"))  %>'>
</telerik:RadDatePicker>

Open in new window

I tried this in the code behind as a separate try to no avail.

 Private Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemDataBound

        If (TypeOf e.Item Is GridEditFormItem AndAlso e.Item.IsInEditMode) Then
            Dim editFormItem As GridEditFormItem = CType(e.Item, GridEditFormItem)
            Dim parentItem As GridDataItem = editFormItem.ParentItem
            Dim dateVendorLastPurchaseDate As RadDatePicker = CType(editFormItem.FindControl("itemLastPurchaseRadDatePicker"), RadDatePicker)
            Dim lastPurchaseDate As String = parentItem("ItemVendorLastPriceDate").Text
            If lastPurchaseDate <> "" Or lastPurchaseDate IsNot Nothing Then
                dateVendorLastPurchaseDate.SelectedDate = lastPurchaseDate
            End If
End Sub

I never got notified that there was a post on here, sorry...I'm checking this out now, I had moved onto something else because it was taking so long, will post back shortly.
So on my ItemDataBound event for the insert, what when I use a Try/Catch is:

System.NullReferenceException: Object reference not set to an instance of an object. at DesktopModules_Inventory_inventoryMain.RadGrid1_ItemDataBound(Object sender, GridItemEventArgs e)
I got it! I just added "And RadGrid1.MasterTableView.IsItemInserted = False" to my If statement on the ItemDataBound and it all worked like a charm! Thanks for the feedback and thanks to the moderators for helping me reclassify this!
You were the only one to respond, so you get the points anyway, thank you!
