This problem is difficult to describe, so bear with me.

I have a user control that I built, that contains a RadAjaxPanel along with a RadAjaxLoadingPanel and some other controls.  I then have an aspx page that contains another RadAjaxPanel and RadAjaxLoadingPanel.  I have wrote some server side code that will add the user control to a panel on the page dynamically when a button within the aspx page's RadAjaxPanel is clicked.  The panel that the control gets added to has been delegated as an UpdateControl in the RadAjaxManager, so as to avoid a complete postback.  I have made sure to write the server side code, so that the user control's ID and all of its containing ctrl's ID's are unique with an incremented number on the end.  This however is not preventing a javascript runtime errors from popping up when I test this in debug.  The errors are as follows:  

"Sys.InvalidOperationException: A control is already associated with the element."
"Sys.InvalidOperationException: Two components with the same id 'dynamicRADAJAXPanelID' can't be added to the application."

I have checked all the control ID's and none are the same.  The web page function properly, and does add the controls dynamically, but still throws the exception.  If I ignore the exceptions, the page renders and functions properly.

If anyone knows of any issues with adding RadControls dynamically, or with adding controls dynamically in an AJAX postback rather than a full postback, please help me out.  If you need to see the code, let me know. 

Thanks.

Hi,

We've just migrated from ComponentArt Menu to Telerik Menu because of client requirenent for two features: Keyboard Access and Multiple browsers support.
We've a fixed horizontal Menu with 6 static MenuItems, out of which, only two have sub-menus. (Menu_Usage.png)
The requirement is that these links should be accessible via Keyboard using Shortcut Keys. This works prefectly with IE - pressing [Alt + <Shortcut Key>] sets focus on the right Menu Item and we can traverse through other Menu Items using 'Tab'-key.
But with Firefox, pressing [Shift + Alt + <Shortcut Key>] doesn't set the focus on the first Menu Item - it makes a click on the first Menu Item! Result is that traversal is not possible at all, as using shortcut keys immediately opens the page by clicking the hyperlink.

I've attached two snapshots from the Telerik Demo opened in IE and FF, with slight code modification to enable Shortcut Keys on one of the Demos. IE - all is fine, but using ShortCut Keys in FF activates (and clicks!) the MenuItem, and navigation via keyboard doesn't work anymore.
FYI, this is the default behavior in Firefox for Hyperlinks
(refer to:   http://kb.mozillazine.org/Accessibility.accesskeycausesactivation)

But I need a solution/workaround. Any ideas?
Thanks in advance.

Hi!

I've simple question: Is it possible to create or fill nested table on client side? Even if columns are specified or not.

I need to create nested table view after row click and expand it. All things should be done on client side, RadGrid control will get data from web service.

Any help is appreciated.

Find and replace is working properly in Rad Editor version 2009.2.701.35. Please suggest.

Thanks

Hi,

I want to add spellchecker in my rad editor.
I have used
Tools file declaration in XMl file as mentioned below.
<tool name="AjaxSpellCheck" shortcut="F7"/>
On using the tool the Spell check  icon gets displayed but the icon is not as the one what we see on using the old Version(a little Blurred).

Please help me to solve this issue.

Note:
When i used the Old version the Icon for the spellchecker in my rad editor was displaying properly( i.e as expected).
Whereas when  used the updated Version i am getting this issue.

I have an issue where I am using the RadFileExplorer in a dialog on a web page. When the control is added to the page and it is always visible, the control width resizes according to its containing div as expected. However if the control is loaded and subsequently resizes accordingly, then it's containing div is made invisible, the window is then resized and the the div is made visible again the RadFileExplorer's width remains the same as when it was initially loaded.

Hi

I've the situation, when I have to explore folder, which is located on the server, differ from my site's server. There is an opportunity to use  WebDAV-protocol fo this. Is it possible to do with File Explorer? Can you tell me, please, how it can be done?

Best regards, John

Hello,

I noticed that there is a Telerik.Pdf namespace, with a class called PdfDocument. The basic API documentation says the class is " A class that enables a well structured PDF document to be generated."

I just wondered if there was any documentation or examples of how someone were to go about generating such a document using that class.

Thanks!
