ModalPopupExtender not working from code behind

Hi all,

I'm trying to invoke a modal popup on a gridview to change user passwords. The modal isn't appearing though? can anyone tell me what I am doing wrong here;

    <asp:HyperLink ID="DummyButton" runat="server" Style="display: none;" />

    <asp:ModalPopupExtender ID="PasswordModalPopupExtender" TargetControlID="DummyButton" PopupControlID="PasswordPopup" runat="server" DropShadow="true" Enabled="true">
    </asp:ModalPopupExtender>
    
    <asp:Panel id="PasswordPopup" runat="server" style="display:none;">
        <asp:ChangePassword ID="ChangePasswordControl" runat="server"></asp:ChangePassword>
    </asp:Panel>

Open in new window


and on the gridview i am capturing the  OnSelectedIndexChanged="OnSelectedIndexChanged"

        ChangePasswordControl.UserName = UserList.SelectedRow.Cells[1].Text;
        FeedbackLabel.Text = "Changing Password for " + UserList.SelectedRow.Cells[1].Text;
        PasswordModalPopupExtender.Show();

Open in new window


now all is firing and the FeedbackLabel is displaying the correct info but the modal doesnt appear?

It may be invoking the popup. Just to make sure it get displaying or not, set BackgroundCssClass property.
Also, if it is inside update panel, make sure, both (grid and ModalPopupExtender) should be in same update panel.

Thanks for the reply.

Will not setting the BackgroundCssClass cause issues? Could you suggest what I should put in here for testing?

The modal is not inside anupdate panel and is just in a standard aspx page with a masterpage.

Utkarsh KulkarniSr. Sw EngCommented:
BackgroundCssClass is an optional attribute. But the css or default setting can do this.
Also, try to access the page in FF & open the Java console to see is there any script error.
Sample CSS

.popup_block{
      display: none; /*--hidden by default--*/
      float: left;
      font-size: 1.2em;
      position: fixed;
      top: 9%; left: 30%;
      z-index: 99999;      
}
.modal_Background
{
      background-color:#CCCCCC;
      filter:alpha(opacity=90);
      opacity:0.9;
      }

as far as I can see there are no errors?

    <asp:ModalPopupExtender ID="PasswordModalPopupExtender" TargetControlID="DummyButton" PopupControlID="PasswordPopup" BackgroundCssClass="tmodal_Background" runat="server" DropShadow="true" Enabled="true">
    </asp:ModalPopupExtender>
    
    <asp:Panel id="PasswordPopup" runat="server" CssClass="tpopup_block">
        <asp:ChangePassword ID="ChangePasswordControl" runat="server"></asp:ChangePassword>
    </asp:Panel>

Open in new window


and css is;

.tpopup_block{
      display: none; /*--hidden by default--*/
      float: left;
      font-size: 1.2em;
      position: fixed;
      top: 9%; left: 30%;
      z-index: 99999;      
}
.tmodal_Background
{
      background-color:#CCCCCC;
      filter:alpha(opacity=90);
      opacity:0.9;
      } 

Open in new window


if I user firebug I can drill down and see the panel is being rendered?

any idea?

You can check using firebug.

Hi,

here is the sample code
 <style>
            .tpopup_block {
                display: none; /*--hidden by default--*/
                float: left;
                font-size: 1.2em;
                position: fixed;
                top: 20%;
                left: 30%;
                z-index: 99999;
                color: #ff0000;
            }

            .tpopup_block_click {
                float: left;
                font-size: 1.2em;
                position: fixed;
                top: 20%;
                left: 30%;
                z-index: 99999;
                color: #ff0000;
            }

            .tmodal_Background {
                background-color: #CCCCCC;
                filter: alpha(opacity=90);
                opacity: 0.9;
            }
        </style>
        <div>
            <asp:ScriptManager runat="server" ID="sm"></asp:ScriptManager>
            <asp:Button ID="bbb" runat="server" OnClick="bbb_Click" Text="Test" />
            <asp:HyperLink ID="DummyButton" runat="server" Style="display: none;" />
            <cc1:ModalPopupExtender ID="PasswordModalPopupExtender" TargetControlID="DummyButton" PopupControlID="PasswordPopup" BackgroundCssClass="tmodal_Background" runat="server" DropShadow="true" Enabled="true">
            </cc1:ModalPopupExtender>
            <asp:Panel ID="PasswordPopup" runat="server" CssClass="tpopup_block">
                <h1>Sample Text</h1>
            </asp:Panel>
        </div>

Open in new window


protected void bbb_Click(object sender, EventArgs e)
        {
            PasswordPopup.CssClass = "tpopup_block_click";
            PasswordModalPopupExtender.Show();
        }

Open in new window


Check this on single page first & then modify for Master Page / Content place holder

hi there.

this still was not working. So as I am really only showing this from the server side I have just removed the popupcontrol and set a panel to be visible=true on the click.

this works well and removes the bloated popupextender control.

thanks for all the help though.
