  Another Strange Behavior in VS Design Mode

  Jul 27, 2017 09:58 PM|NJ2|LINK

  Do you see any thing wrong with the following code?

  I want to create a Button1_Click event for Button1 but the property page is grayed out in design mode. I manually created the event but clicking on button won't execute this code. I am trying to refresh a GridView on parent page from AJAX Popup is closed.

  protected void Button1_Click(object sender, EventArgs e)
  {
     ProcessMyRequest();
  }

          <asp:ModalPopupExtender ID="ModalPopupExtender1" runat="server" PopupControlID="Panl1" TargetControlID="lnkProcess"
                      BackgroundCssClass="Background">
          </asp:ModalPopupExtender>
  
          <asp:Panel ID="Panel10" runat="server" CssClass="Popup" align="center" style = "display:none">
              <iframe style=" width: 500px; background-color:lightsteelblue; height: 400px;" id="Iframe2" runat="server"></iframe>
              <script>
                  (function () {
                      var pageurl = "WebForm1.aspx?Module=Mod1";
                      var txtCourseValue = document.getElementById("txtCourse").value;
                      if (txtCourseValue != undefined) {
                          document.getElementById("Iframe1").src = pageurl + "&Page=" + txtCourseValue;
                      }
                  })();
              </script>           <br/>
              <asp:Button ID="Button1" runat="server" Text="Close" CausesValidation="False"/>
          </asp:Panel>

  Yeah, you set the style to display: none.  Use the property window from the HTML code view to generated the click handler.

  Also set the button's UseSubmitBehavior property to false

   <asp:Button ID="Button1" runat="server" Text="Close" OnClick="Button1_Click" UseSubmitBehavior="false" />

  Thanks,

  Hi NJ2,

  According to your description, I noticed that you put the button inside the panel, but you set the property display of button to none. So I think this make it grayed out.

  Also I think about how to add click event to button, please check the following sample code:

  Page:
  <asp:Button ID="Button1" runat="server" Text="Change" OnClick="Button1_Click" />
  
  Code Behind:
  protected void Button1_Click(object sender, EventArgs e)
      {
           ProcessMyRequest();
      }

  Best Regards,

  Eric Du
