I am using Telerik 2013.1.220.35.
I have a fairly basic Application Page.
Also, the C# part.
Normally, I would expect this to work
(In fact, it works in RenderMode Native).
However, as soon as I try to expand the ComboBox, I get this error.
Line: 1617
Erreur : 'top' a la valeur Null ou n'est pas un objet.
Translate to: 'Top' is null or not an object
I tried to debug it.
I added a comment where it breaks. This problem is fairly bizarre. I'm pretty sure I have everything that is required. The ScriptManager is there and is in a Form tag that is runat="server". I can select an item using the text selection and it works. It just never render the items. The error also trigger if I try to resize the window (after I chose to continue after the debug).
I hope you can guide me on the right path.
