ASP.Net/AJAX - Events not fire after loading usercontrols dynamically in asp.net with c#

Question

I have loaded a user control dynamically using jquery ajax in my asp.net application.

Every thing is working fine except after the user control loaded an asp.net link button on the page is not firing the click event. The link button is not dynamically loaded.

Please help me to resolve the issue.

Thanks

I know that this question was asked 5 years ago but I came today and get stock with the same issue. Maybe my answer can help anyone. Based on this article you cannot fire a click event when creating your user control in this way. You have then to rely on buttons handled from client side. if you try to add your user control to your page not dynamically, events will be fired as the page is loaded (check here)

you can try like this .....

NOTE : this is an example .....if you specify your user control(code) then it will be useful ....

Assuming the name of the type follows the name of the file, you can strongly-type it to that type, such that,

var myUserControl = Page.LoadControl("~/View/EditScheduleProgram.ascx") as EditScheduleProgram;

Then you have access to any custom (or specific) events exposed by that type but not by Control, so,

myUserControl.MyEvent += MyEventHandler;
