Hi,

The error is caused due to the fact that you have assigned a page as the UserControlName in your EditFormSettings instead of a WebUserControl . A suggestion would be to use either the window editing approach  or make use of a User Control Edit Form  to contain the edit form .

Hope this helps.

Thanks,

Hello Princy

Thanks a lot for your reply, i am using edit in template now (with the help of this video:
http://tv.telerik.com/aspnet/radgrid/radgrid-+-edit-templates)
and it is working fine except:

* The insert and update buttons as a beginner in asp.net i could not get it right to work with me in visual basic as he uses C# code on the tutorial.
(the code is to change the text from update to insert depends on the user choice).


* if i switch from editForm to popup everything work fine except the RadComboBox i can type in it and the matching choice appears but no drop down menu, i am not sure if i change the Zindex will help or not - it is 8000


any help will be appriciated

Hi,

Please take a look at  the VB syntax for the Update/Insert buttons in the EditForm Template:

<asp:Button ID="btnUpdate" Text='<%# IIf((TypeOf(Container) is GridEditFormInsertItem), "Insert", "Update") %>' runat="server" CommandName='<%# IIf((TypeOf(Container) is GridEditFormInsertItem), "PerformInsert", "Update")%>'>

Thanks,

Princy
