Hi,

I posted several threads in various Telerik AJAX forums and have not had replies to all.  I will try posting here since I'm using the courseware and encountering problems doing the lessons.  Hopefully, I'm in the right place now :)

1. Unable to see the Tool tips in the column header of the RadGrid
   PDF pg 459
   
   

   Protected Sub RadGrid1_ItemCreated(ByVal sender As Object, ByVal e As GridItemEventArgs)

   'Check for GridHeaderItem if you wish tooltips only for the header cells

   If TypeOf e.Item Is GridHeaderItem Then

   Dim headerItem As GridHeaderItem = TryCast(e.Item, GridHeaderItem)

   headerItem("CreditRating").ToolTip = "CreditRating"

   headerItem("PreferredVendorStatus").ToolTip = "PreferredVendorStatus"

   headerItem("ActiveFlag").ToolTip = "ActiveFlag"

   End If

   End Sub

    
2. Unable to drag and drop rows within a RadGrid
   PDF pg. 475
   
   

   Protected Sub RadGrid1_RowDrop(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridDragDropEventArgs)

   Dim item As GridDataItem = TryCast(e.DraggedItems(0), GridDataItem)

   RadAjaxManager1.Alert("Dropped VendorID: " + item.GetDataKeyValue("VendorID"))

   End Sub

3. Unable to delete records in a RadGrid
   PDF pg. 472
   
   

   [T-SQL]

   DELETE FROM Purchasing.[Vendor] WHERE [VendorID] = @VendorID

   
   Javascript error:
   
   

   Line: 7

   Char: 62099

   Error: Sys.WebForms.PageReuestManagerServerErrorException: The transaction ended in the trigger.  The batch has been aborted.  Vendors cannot be deleted.  They can only be marked as not active

4. Item insert code not working
   PDF pg. 477
   
   

   Protected Sub RadGrid1_ItemInserted(ByVal source As Object, ByVal e As GridInsertedEventArgs)

   If e.Exception <> Nothing Then

   e.ExceptionHandled = True

   e.KeepInInsertMode = True

   DisplayMessage("Product cannot be inserted. Reason: " + e.Exception.Message)

   Else

   DisplayMessage("Product inserted")

   End If

   End Sub

The compilation error I get using the code in #4 is:
Compiler Error Message: BC30452: Operator '<>' is not defined for types 'System.Exception' and 'System.Exception'.

Also, within the code, there are squiggly lines under "DisplayMessage".  The caption is "Name 'DisplayMessage' is not declared".  I understand how to declare a variable, but what should I declare it as?

Thanks very much for all help,

I've just installed Telerik and have reinstalled VS 2008 (latest).
I tried a simple website project and dragged a ScriptManager onto the page and get the error:

Error Rendering Control - RadScriptManager1

An unhandled exception has occurred.
Could not load file or assembly 'Telerik.Web.UI, Version=2009.1.311.35, etc ..system cannot find the file specified.

I have manually browsed to the bin35 folder and added the Telerik DLL from there, still the same error.

Nothing's working with this installation! Theres no contextual Smart Tag available, and VS crashes if you change a property in a control.

Help!!

Hi,
