Render() vs. CreateChildControls() in composite control

Hi,

can I use any method in CreateChildControls() which adds child controls (defined in aspx) at the position I want?
In Render method I can use base.RenderChildren() whenever I want.

Example code (ASPX):



<my:row>


	<asp:Label ID="labelID" Text="middle"/>


</my:row>

Example code (CS):



    public class Row : Control, INamingContainer {


        protected override void Render (HtmlTextWriter writer) {


            writer.Write("first - ");


            base.RenderChildren(writer);	// OK


            writer.Write(" - last");


        }





        protected override void CreateChildControls() {


            Controls.Add(new LiteralControl("first - "));


	    // ? HOW ?


            Controls.Add(new LiteralControl("- last"));


        }


    }

I use both! I use the render method to build a table that all my pages will display. And I use the createchildcontrols method to add a usercontrol and some buttons to a row in the table that the render method builds.

It's been a while, but I believe if you step through the code, you will see that render calls the createchildcontrols method.

HTH,
Drew
