body: <pre><code>&lt;asp:Panel ID="CreateGroupPanel" runat="server" 
             CssClass="style10" Visible="True" &gt;
                  &lt;asp:ToolkitScriptManager ID="ToolkitScriptManager1" 
                                            runat="server"&gt;
                  &lt;/asp:ToolkitScriptManager&gt;
                  &lt;asp:UpdatePanel ID="UpdatePanel1" runat="server"&gt;
  ....
  &lt;/ asp:UpdatePanel&gt;
  &lt;/asp: Panel&gt;
  
  &lt;asp:Button ID="Btn_CreateGroupPopUp " 
              runat="server" 
              Text="Create Group" 
              Width="109px" /&gt;
  &lt;asp:PopupControlExtender ID="PopupControlExtender1" runat="server"
                            DynamicServicePath=""
                            Enabled="True" ExtenderControlID="" 
                            TargetControlID="Btn_CreateGroupPopUp" 
                            PopupControlID="CreateGroupPanel"&gt;
  &lt;/asp:PopupControlExtender&gt;
  </code></pre>
  
  <p>here the panel is popup when button btn_CreateGroupPopUp is clicked. It works fine with internet explorer, but when I open the website in chrome, the pop up comes and then the page refreshes automatically and the pop up is closed. What is the problem with this, I don’t have any time or meta refresh in my page.</p>
