To add an ASP.NET user control to a Web page
In Visual Web Developer, open the Web page to which you want to add the ASP.NET user control.
Switch to Design view.
Select your custom user control file in Solution Explorer, and drag it onto the page.
The ASP.NET user control is added to the page. In addition, the designer creates the @ Register directive, which is required for the page to recognize the user control. You can now work with the control's public properties and methods.
