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"

I am having an issue with people visiting my site using ie8. It appears that some of my pages seem to render, then disappear. It is only happening in IE8. I looked up a few things on the web and found a few bugs within the browser:

I tried implementing the changes but am still having issues. I suspect it is something within the styles of my controls pages or within the CSS file.

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.

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>

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.

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.

I have a modal popup extender with one control (ascx) this control has a label that on onclic method call other popup extender.
It's has other ascx, it's has a button for a search. When I do Click in this button in first time, the event click not fired and there are a javascript error that say "this._activeDRagVisual is null reference".
In the other hand, If a use de second popup inside an asp page the event and control work correctly. The problem is with the popup inside popup.

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:

I have a modalPopupExtender in my aspx web page pointing to a Panel and in Code-Behind I create buttons which I want them to show the modalPopup, so I have:
buttonX.OnClientClick = "javascript:$get(" + modalPopup.ClientID + ").show();";
but instead it just does a PostBack, even if I put "return false;" at the end of the past code.

I have a small standalone development project and am designing a form page in it.
It has a CalendarExtender, I notice that when it is initially popped up it is blank appart from the left/right arrow.
Pressing an arrow and the month appears OK and from then on it's OK.
If I create a brand new project and paste the code in it then works OK.
So it must be something in my project I think.
