This control is relatively simple. It has been available since Microsoft released the Ajax predecessor Atlas, and its functional applications are also quite common. This example has already been implemented, now I am not busy with my work and send it to new users for reference and learning. Code :
<% @ Page Language = " C # " Autoeventwireup = " True " Codebehind = " Collapsiblepaneldeml. aspx. CS " Inherits = " Apptestajax. collapsiblepaneldeml " %>
<% @ Register assembly = " Ajaxcontroltoolkit " Namespace = " Ajaxcontroltoolkit " Tagprefix = " PC3 " %>
<! Doctype HTML public " -// W3C // dtd xhtml 1.0 transitional // en " " Http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd " >
