AJAX :: ModalPopupExtender Appears And Then Disappears On Show()?

Aug 6, 2010

I have a modalpopupextender and I want to show a panel after a postback which works but once the panel is shown it disappears immediately. Upon reviewing the markup, it seems as though some inline styles are being set.

style="display:none; position:fixed"

If I edit the display attribute and change it to block then the panel will displayed with all its rendered content but I need it to display after a postback. After troubleshooting the only conclusion i have is that the modalpopupextender is setting the inline styles, because when I turn off the modalpopupextender, then the Panel will show correctly.

<asp:ModalPopupExtender ID="modalPopupExtender1" runat="server"

AJAX :: ModalPopupExtender Allows Content Panel To Show, But Everything Is Disabled?

Sep 15, 2010

I have a user control (ascx) vs 2010 that contains a modalpopup extender thats popup control is an asp:panel. In that Panel I have an update panel and a contenttemplate inside the upd panel. It is a pretty simple example of its use, in that I have list box allowing the users to create a new row in a table.

However, when I click targetcontrol, the background changes to the expended modal background, but instead of being able to use the listbox, everything in the content panel is the same as the background and none of the controls on the panel are enabled. In other words, the entire page is loaded dimgray, including the updatearea.

AJAX :: AjaxToolkit:ModalPopupExtender To Show A Modal Window Panel

Feb 25, 2010

I use ajaxToolkit:ModalPopupExtender to show a modal window panel. The panel among other things contains a "Submit" button. I would like to call a code behind function on Submit. First I tried this:

[Code]....

But btnSubmitOnHold_Click() is never called. Then I replaced OnClick="btnSubmitOnHold_Click" with OnClientClick="SubmitPutOnHold" and added

<script type="text/javascript">
function SubmitPutOnHold()
{
alert('blah');
}
</script>

This alert also never shows up. Finally, I tried

<ajaxToolkit:ModalPopupExtender ID="OnHoldModalPopupExtender" runat="server" TargetControlID="btnPutOnHold" PopupControlID="pnlOnHold" BackgroundCssClass="modalBackground" DropShadow="true" OkControlID="btnSubmitOnHold" CancelControlID="btnCancelOnHold"
OnOkScript="SubmitPutOnHold" >
</ajaxToolkit:ModalPopupExtender>

AJAX :: ModalPopupExtender: After Postback, Client-side Show() No Longer Works

Mar 23, 2010

I'm using what I believe is a pretty common/boring/generic implementation of a ModalPopupExtender. I'm using client-side JS to show the dialog when the user clicks a link, and hide it if they click "cancel". I only do a postback if they truly want to save the data.

I can click the link to show the dialog, then click the cancel button to hide it, then click the link to show it... ad infinitum. If I decide to save the data via a postback, everything works well, and the dialog is hidden as a result of the postback, all as expected.

However, once the postback completes, my client-side JS show() never works again. Any attempts to click the link fail quietly; no error messages, the dialog just never shows again.

AJAX :: ModalPopupExtender -- Fetch Data In Modalpopupextender

Apr 7, 2010

I would really appreciate if someone can find out what's wrong with this code.

Here is my question. I have textboxes in a modal popup extender (City, state, zip) and there is an image button search for searching the address from the database. All this functionality is within a control (.ascx file). This control is added to the page where it needs to be displayed and is being displayed when a user click the Address button (the code for it is not shown here). The method ShowAddressSearch() in the control is being called from the page and it displays the popup.

When the user enters any of the 3 values and hits search a server event is fired up and the result should be displayed in a grid. What is happening is, when the user hits the search button the server call is made and the data fetched from the db but the modal popup closes itself here is the code for this. I would really appreciate if someone can find out where and how popup is getting closed.

ModalPopupExtender Doesn't Work On IE6 Frame Layout

Jun 15, 2010

I'm using a "frame" layout similar to the one in this excellent answer: a div #top at the top of the page, a div#left on the left, and a div #main with the main content. The #top and #left divs contain navigation menus.Now I want to use a popup div using the AjaxControlToolkit ModalPopupExtender inside the content (#main) div.This works fine on IE8 (where #top, #left, #main all have position:fixed), but when I run it on IE6, the modal background only covers the #main div - I need it to cover the whole of the page including the #top and #left navigation divs.

ModalPopupExtender Z-index Value Decreases After Every Show

Apr 21, 2010

I have a gridview containing a bunch of categories that can be edited by clicking on the respective "Edit" link within the gridview. The modalpopupextender is then shown programmatically (.show() method) and the user is allowed to edit the category. Then the modal popup is programmtically hidden (.hide() method) when the user presses "Update" or "Cancel". For some reason after every new show of the modal popup, the z-index is decreasing by 1000 until it is hidden behind everything on my page. It starts at 7000 for the very first show. Therefore the user would not be able to edit an infinite number of categories if they wanted to.

Css class used on modalpopupextender:
