Issue selecting from RadComboBox

[David]

I am trying to select an item from, what I think, is is a generic RadComboBox. I can use the Open method but an item cannot be selected.

The error I get when trying to select by Index, by Text or by Value is:
ArtOfTest.WebAii.Exceptions.ExecuteCommandException was unhandled by user code
  Message=ExecuteCommand failed!
InError set by the client. Client Error:

Hello David,
try adding a fixed delay of a few seconds between the Open step and Select step. Does the issue persist?

That being said, we would like to reproduce this issue locally. Please check out whether you can reproduce this on our demo controls here:
http://demos.telerik.com/aspnet-ajax/combobox/examples/overview/defaultcs.aspx

If not, than could you put together a sample that (or grant us access to the original app) so that we may reproduce this locally.

The other alternative is to send us a Fiddler trace as seen here:
http://tv.telerik.com/watch/automated-testing-tools/test-studio-creating-fiddler-trace

If you feel any of the info you would like to send us is too sensitive for a public forum, please go ahead and open a Support Ticket and attach it there. The support system (available only to paying customers such as yourself) is 100% confidential.

Kind regards,
Stoich
the Telerik team
