do you want the contents of the user control returned as a string?

goodkAuthor Commented:
yes; the UC is html only -

hosneylkCommented:
you could create a control on the page and hide it. then you could do something like this..
StringWriter writer = new StringWriter();
HtmlTextWriter htmlWriter = new HtmlTextWriter(writer);
WebUserControl11.RenderControl(htmlWriter);
string ctrlOutput = writer.ToString();

I want to know how I could return the control WebUserControl11instead of tempstr? Where WebUserControl11 is a html page saved as a control.
      public static string addMenu()
        {

                    <uc1:WebUserControl1 ID="WebUserControl11" runat="server" />
           
            return tempstr;
        }

use System.IO.StringWriter or use the namespace System.IO

you can drag and drop the control into your page so that it creates an instance of it. then you could set the style of the control to display:none.

just cannot make it work!!

All I want to know is how to include an html page control into html page - not drag and drop but programitically.

Just if stupid microsoft would allow INCLUDE files.  Or some way to attach a working html page into another html page? but Programitically.

Drag and Drop of control file works. Why I cannot make the same thing works programitically??

I am all confuse. please help - thanks
