Environment

Product Version	2014.2 618+
Product	RadButton for ASP.NET AJAX

Description

The missing web resource name error happens after an upgrade from a version prior to 2012 to a version after 2014. Telerik UI for ASP.NET AJAX.

Solution

Telerik UI for ASP.NET RadButton has been heavily refactored in 2014 and its combined scripts file was renamed to Telerik.Web.UI.Button.RadButtonScripts.js.

If you are loading the RadButton scripts manually - you need to modify this line

<asp:ScriptReference Path="~/Scripts/Button/RadButton.js" />

with this one:

<asp:ScriptReference Path="~/Scripts/Button/RadButtonScripts.js" />

OR

<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Button.RadButtonScripts.js" />

OR to load RadButton scripts from CDN. You can also enable a local CDN.
