I am trying to add a user control in Web.Config file as below,
< controls> < add tagPrefix="MyControl" tagName="MyUserControl" src="/MyUserControl.ascx"/> < /controls>It gives me following error,
Configuration Error: The relative virtual path 'MyUserControl.ascx' is not allowed here.
SolutionTo resolve this issue, move your WebUserControl from root directory to a sub directory. For example in my case, I would copy MyUserControl.ascx to sub folder "Controls". So my Web.Config entry should look like below.
< controls> < add tagPrefix="MyControl" tagName="MyUserControl" src= "~/Controls/MyUserControl.ascx"/> < /controls>~ indicates relative path from root folder.
This is one of the limitation of ASP.Net application. It does not allow you to register user control in Web.Config file unless it's in a subfolder.
