In the Sharepoint project we have added few resource files and mapped them to Sharepoint resource folder(Delpoyment location-{SharePointRoot}\Resources).
using the below code, we tried to read resource string value from webpart design page(ASCX)
asp:Label ID="lblID" runat="server" Text="<%$Resources:ResourceFileName, ResourceKey%>"
The code was working well in sharepoint 2010 and but for sharepoint2013 we are getting exception as "The name 'InitializeControl' does not exist in the current context".
please help us.
