There is nothing stopping you from instantiating a page which contains the user control. For example, this is your page: 


public class MyWebServicedPage : Page() {


   public void FireEvents() {


      EventArgs e = EventArgs.Empty;





      OnInit(e);


      OnLoad(e);


      OnPreRender(e);


   }


}

And from the web service: 


StringWriter tw = new StringWriter();


HtmlTextWriter writer = new HtmlTextWriter(tw);


MyWebServicedPage page = new MyWebServicedPage();





page.FireEvents();


page.RenderControl(writer);


return tw.ToString();

Hi

thanks , but it doesn't work!.
I have a server control on my user control page that it will be bind by one of user control's method.
but with your code , when I call the method , this control point to null (Nothing in VB.Net) and then it has not been istanciate correctly(or render)

fortunately I found the way :

Dim TempPage As New Page
dim myu as MyUserControl = CType(TempPage.LoadControl("/users/admins/services/MyUserControl .ascx"), MyUserControl )

TempPage.Controls.Add(myu)

it works fine!
