Today one of my colleague (Aneesh, the one who wrote this post) asked me how can we add Web user controls dynamically in to a web page. I tried to do like Controls.Add(..) and placed a asp:placeholder and tried. But every time it is getting added without any error, but it is not getting displayed. 
After doing some search I got some code snippet, which helps you to Add Web user controls dynamically on web pages.
Dim oWebUserControl1 as WebUserControl1 = Ctype(Page.LoadControl("~/WebUserControl1.ascx"),WebUserControl1)
Me.PlaceHolder1.Controls.Add(oWebUserControl1)
