    While using Ajax control toolkit in my website and I have created Ajax control toolkit modal popup extender in my page.
    Every thing is working fine but when I am pressing any button on page or selecting any dropdownlist page reloads and it shows My modal popup extender for few seconds. It disappears when page is completely reloads.

    How to solve this issue?

               To stop showing your Ajax control toolkit modal popup extender on postbacks make your Panel visible false. Example:

    <asp:Panel ID="PnlPopup" runat="server" Visible="false" CssClass="message">
