[Solved] AutocompleteExtender. Sys.InvalidOperationException: Handler was not added through the Sys.UI.DomEvent.addHandler method

[igor]

Hello,

I have just started with teleriks. I am using the RadControls_for_ASP.NET_AJAX_2008_3_1314_trial. I am also working with VS2005 and .NET2.0

I have a normal Texbox with one AutoCompleteExtender and it works fine when the page is first loaded. But afterwards every time the page makes a postback or i close the browser, I get the next message:

"Microsoft JScript runtime error: Sys.InvalidOperationException: Handler was not added through the Sys.UI.DomEvent.addHandler method"

the structure of the web site is like this:
Masterpage:
    scriptmanager
    Telerik Ajaxmanager
    RadFromDecorator
    RadMenu
    RadCombox
    Texbox and AutoCompleteExtender.
    Contents..
In the AjaxManager i make no reference to the texbox or to the autoCompleteExtender.

If i delete the AutoCompleteExtender everything works. It is there any example of this ajax tool with master-pages and Ajaxmanager?

Thanks!

Hi igor,

Based on this information, it is very hard to pinpoint the cause of the problem. If the issue persists, you can open a formal support ticket, and send us a small implementation, demonstrating the setup and hand, and the unwanted behavior. We will review it locally, and get back to you with additional information.

Hi,

I got this same error when I implement the autocompleteExtender inside a RADAjaxPanel.  Were you able to resolve this?

Hello Andreas,

This forum thread is quite old so I am not sure what exactly is the problem that you experience. If you are using a recent version of the controls and the problem is the same as the one described in this forum thread, please send us a sample project in a support ticket so we could investigate further.
So far, the only problem that we discovered in a scenario where RadFormDecorator is present on a page with autocomplete extender on it is the size of the dropdown with the suggested words. This issue is present in IE only and can be fixed with the following CSS hack:

#AutoCompleteEx_completionListElem
{
    margin-left: 4px\9 !important;
    margin-top: 8px\9 !important;
}

#AutoCompleteEx_completionListElem li
{
    font-size: 12px;
}

Sincerely yours,
