How to use the pop-up dialog box in Ajax __ajax

After using Microsoft's AJAX controls, you want to implement pop-up statements that no longer use Response.Write ("<script>alert" ("Success"). ');</script> ");

and to use Scriptmanager.registerclientscriptblock (UpdatePanel1, this. GetType (), "Click", "Alert (' success.  ') ', true); Replace.

Note: If there is more than one UpdatePanel in the page, if each UpdatePanel UpdateMode is "always" [Default value],

Then you can use the instance of that UpdatePanel as a parameter; if each Updaepanel updatemode=conditional,

Then you must use the UpdatePanel that is being updated as an argument so that the script will work.
