                        user1.Visible = true;

         }

    Master.aspx

    &lt;div id="divChatUserControlCover" runat="server"&gt;

            &lt;/div&gt;

<p>Ok I have edited the code and now I have created properties. How do I call the DataBind method for rpChatMessages? I also cant see my usercontrol on page. Why</p>
