• Changed code-behind as well as markup in YAF source code project for the file controls/YafHeader.ascx.cs, by adding below code

• Rebuild the source code project containing above changes

• Copied over YAF.dll from bin folder of above YAF project to the YAF project without source code

• Added the same custom markup to controls/YafHeader.ascx in YAF project without source code

<asp:PlaceHolder runat="server" id="phCustom"></asp:PlaceHolder>
<div id="yafheader">

        protected void Page_Init(object sender, EventArgs args)
        {
            LiteralControl html = new LiteralControl("<h2>Testing user control code</h2>");
            phCustom.Controls.Add(html);
        }

I found out after some research, that it was an issue on my end. The YAF.dll in my project was being overwritten by old YAF.dll since the reference to it was pointing to the same file of an older version under another folder. So copying the new YAF.dll was not doing anything.

But I still have a question related to this and that is as below.
Is there any other way of extending the standard user controls under controls folder in YAF project?
