. As controls are not aware that they are being updated by AJAX (rather than a postback), they cannot restore their client-side functionality as the HTML element is being replaced by a new object. The control, which is to be updated via AJAX request has to be pre-modified to work with XmlHttpRequests
. This should be done by its vendor, therefore please contact the control's vendor for further help on the issue.
One thing you can try is to register the controls scripts manually, by adding script reference through the ScriptManager for instance.
Another cause of the problem could be if the control does not render in a single tag. You can check this by viewing the page's source. If this is so, you should nest it in an ASP Panel or a DIV tag.
