ASP.NET Custom Controls - Composites

Question

Summary

Hi All,
OK, further into my adventures with custom controls...

In summary, here is that I have learned of three main "classes" of cus

Answer 1

Here's another extension method that I use for custom rendering:

 public static void WriteControls
        (this HtmlTextWriter o, string format, params object[] args)
 { 
    const string delimiter = "<2E01A260-BD39-47d0-8C5E-0DF814FDF9DC>";
    var controls  = new Dictionary();

    for(int i =0; i < args.Length; ++i)
    { 
       var c = args[i] as Control; 
       if (c==null) continue;
       var guid = Guid.NewGuid().ToString();
       controls[guid] = c;
       args[i] = delimiter+guid+delimiter;
    }

    var _strings = string.Format(format, args)
                         .Split(new string[]{delimiter},
                                StringSplitOptions.None);
    foreach(var s in _strings)
    { 
       if (controls.ContainsKey(s)) 
           controls[s].RenderControl(o);
       else 
           o.Write(s);
    }
}

Then, to render a custom composite in the RenderContents() method I write this:

protected override void RenderContents(HtmlTextWriter o)
{ 
    o.WriteControls
         (@"

               

                    
{0}
                    
{1}
               
             
"
            ,Text
            ,control1);
 }
