Is it possible to use ajax controls (as it is) inside a user control?
thanks
Not sure what you mean by "as it is", but the answer is yes, you can use AJAX in user controls.
The normal practices regarding user controls still apply - using the ScriptManager in order to control javascript instances on the page, proper usage of ViewState etc.
Your question is rather vague, hence the fairly vague answer.
Yes you could use controls from the Ajax Control Toolkit in user controls. Just make sure that the page that hosts the user control has a ScriptManager or preferably a ToolScriptManager.
Now things will change and need special attention when you use Dynamically loaded User Controls ( On Demand ) and Ajaxify them. Ajaxifying Dynamically loaded User controls at run-time though is simple and straightforward could be challenging... Hope this answers ur Q
