Hello Viswanathan,

I have tested the provided code and everything is working fine. Could you please clarify what error occurs at your side (a video will be helpful). Also give us more details about your environment - browser and Telerik RadControls version.

I have been working on the issue for the last couple of days and ultimately uninstalled trial and licenced versions of Telerik and installed ONLY the licenced version to solve this.

No issues now. Thank you

Hello Viswanathan,

I am happy to hear that everything is working fine at your side. This is weird issue and we have never experienced such problem. In case that you have some steps to reproduce it, we will debug the javascript code and determine what causes it.

I am having the same problem. I get this error: 

SCRIPT5009: 'WebForm_InitCallback' is undefined 
default.aspx, line 243 character 1

and this is the line of code causing the error

WebForm_InitCallback();Sys.Application.add_init(function() {
    $create(Telerik.Web.UI.RadComboBox, {"_dropDownWidth":0,"_height":0,"_postBackReference":"__doPostBack(\u0027ctl00$ContentPlaceHolderHeader$SkinChooser\u0027,\u0027arguments\u0027)","_skin":"Outlook","_text":"Outlook","_uniqueId":"ctl00$ContentPlaceHolderHeader$SkinChooser","_value":"Outlook","clientStateFieldID":"ctl00_ContentPlaceHolderHeader_SkinChooser_ClientState","collapseAnimation":"{\"duration\":450}","expandAnimation":"{\"duration\":450}","itemData":[{"value":"Black"},{"value":"BlackMetroTouch"},{"value":"Default"},{"value":"Glow"},{"value":"Metro"},{"value":"MetroTouch"},{"value":"Office2007"},{"value":"Office2010Black"},{"value":"Office2010Blue"},{"value":"Office2010Silver"},{"value":"Outlook","selected":true},{"value":"Silk"},{"value":"Simple"},{"value":"Sitefinity"},{"value":"Sunset"},{"value":"Telerik"},{"value":"Vista"},{"value":"Web20"},{"value":"WebBlue"},{"value":"Windows7"}],"localization":"{\"AllItemsCheckedString\":\"All items checked\",\"ItemsCheckedString\":\"items checked\",\"CheckAllString\":\"Check All\"}","selectedIndex":10}, null, null, $get("ctl00_ContentPlaceHolderHeader_SkinChooser"));
});

Hi Jerry,

It is possible that the encountered problem is caused by incorrectly loaded ASP.NET AJAX framework. The fact that WebForm_InitCallback is not initialized means that the execution of the script was terminated before this function is declared. Nevertheless, I cannot determine the exact cause of the issue from the provided information.

If you are still having difficulties, please open a support ticket and send a simple, fully runnable project that isolates the problem so that I can inspect it locally and provide a more to the point answer. An additional information that could be useful is the current version of UI for ASP.NET AJAX you are using, the browsers in which this occurs and whether the problem happens if you replace the RadComboBox with another AJAX control.

Regards,
Slav
