hello,
since i switched computers i copied the solution and thought it was a nice time to change the ajaxtoolkit.dll with a new version. so i downloaded the latest version and added the reference. when i compile, there is nothing wrong in visual studio 2008. (it's a webapplication) but when it runs i get a: there are multiple controls with the same id. i found out that when i disabled the ajax accordion control it runs well.
i found the solution on this website: http://forums.asp.net/t/1457688.aspx
but now i can't use the accordion control... how can i update the accordion control?
thanks in advanced
