(not trying to run the sample solution?)<br /> <br />Is it possible your AjaxControlToolkit.dll is not recent (from v1.0 release?) If so, you can try downloading the recent version from http://www.codeplex.com/AtlasControlToolkit and make sure you refresh your project references.<br /> </div>AndyBeaulieuMon, 05 Mar 2007 17:58:13 GMTAjax 1.0: 20070305055813Phttp://www.codeplex.com/ajaxsprite/Thread/View.aspx?ThreadId=7778<div class="wikidoc"> I try to use Ajax Sprite with the Ajax 1.0 but doesn't work.
