I have an application that was given to my by someone else and it's using telerik controls.
the application is originally written in VS2010 framework 4.
when i try to open it on my end, i keep getting errors saying "failed to create designed "Error Creating Control - RadScriptManager1Failed to create designer 'Telerik.Web.UI.RadScriptManager, Telerik.Web.UI, Version=2011.1.519.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4'"
the telerik.web.ui.dll file is in my "bin" folder.
am i missing something? is there a way to get the site to work without having to buy these controls? what do i do?
