hi,
I have a grid within a WebUserControl, to edit the rows i use a editform the type WebUserControl, I noticed that if within editform use RadTextBox or RadCombobox do not work, RadCombox not deployed and the RadTextBox returns the value of Textbox, I've changed These controls for their homonyms of ASP.NET and everything works.
It may be a limitation or am I doing anything wrong?

Hi David,

Both RadComboBox and RadTextBox should successfully appear in a web user control used for editing items in RadGrid. If you share with us some sample code we can examine, we might be able to advise you better on the problem you are having.

Hello there!

I have the same problem as David S├ínchez has.

Basicly I'm rendering a control inside a placeholder on the page. That control renders a Gird and the grid has a webusercontrol for the edit form. The place holder is inside a RadAjaxPanel. I figured that if a remove the RadTextBox the javascript error dissapear...

Am I doing anything wrong?

Tks in advance.

Hi,

Please find attached a sample page with two web user controls (one for RadGrid and another for RadGrid's edit form). The page is ajaxified using RadAjaxPanel. Both the textboxes and RadComboBox renders as expected.

Please see how this sample relates to your cases and let me know if it helps.


Sincerely yours,

Sorry Veri, After having read my first post, i notice that my english is very very bad (i'm from Spain) so, sorry.
I will explain better the problem.The issue is that the radcontrol (i have tried several of them) that  i use in a custom EditForm  of a Radgrid that was dynamic loaded inside webusercontrol seems like don't reponse to any event.
I hope that with this explanation and the code previous posted you can find the problem.
Thank you very much.

Hi David,

The issue is discussed in the following public forum thread. The fix for it will be included in the Q2 2008 SP2 version of RadControls for ASP.NET AJAX, expected at the end of this month. If this is something urgent for you, request the latest internal dev build via our support system.

Kind regards,
Stephen
