Returning to an old app to do some maintenance after many years.

Trying to add a new RadGrid to the Webform, but dropping it on the form has no effect.

I can add non-Telerik controls from the toolbox with no problem.

Hopefully this is some version issue, but I can't figure it out.

Is there an easy fix for this?

Hi Peter,

Can you please try the following:

  1. Create an empty aspx page in the root of your ASP.NET Web Forms application
  2. Open the VS toolbox, select RadGrid or another Telerik AJAX component and drag and drop it in the ASPX page.
  3. Perform the same test in Design and Source view of the WebForms page.

What happened? Does the control get created?

If nothing works, do the following:

  • Install the latest version 2022.R1 SP1 of Telerik UI for ASP.NET AJAX
  • Install all available Visual Studio updates since it could be due to a bug in the IDE
  • Restart your machine
  • Try to drag and drop from the toolbox once again.

Yes - that's working on a new blank form.

Going back to an existing form, it's also now working.

I never will entirely figure out Webforms!

Thank you very much!
