Sorry that I don't know how to make a correct question.
I am going to customize urlcontrol.aspx and rename it so it doesn't conflict to existing one. I will change the code behind of my_urlcontrols.ascx from the source version of DNN. However, I don't know how to put it into my project. In my knowledge, I have to follow these steps:
-Recompile DNN source version and get the DotNetNuke.dll.
-Put DotNetNuke.dll into my existing project.
-Put my_urlcontrols.ascx into /controls/ in my existing project.
-Use it as using urlcontrols
Please correct me if I am wrong.
Is there any another way to use custom control?
Thank in advance.
