Commented Issue: ModalPopExtender Problem [27995]

Up until now I had been using Ajax Toolkit v.v4.0.30319. The ModalPopupExtender had worked as expected.

I just installed v15.1.4. I just started a new project and am having the following issue with this control.

Setup up as follows:

<ajaxToolkit:ModalPopupExtender
ID="InfoModal"
TargetControlID="hidForOpen"
runat="server"
CancelControlID="hidForClose"
DropShadow="true"
PopupControlID="pnlUser"
BackgroundCssClass="ModalPopupBG">
</ajaxToolkit:ModalPopupExtender>

This worked great on v.4

This happens consistently. Works great three times by clicking a button and running InfoModal.Show(). Closing by clicking another button.

On 4th click to open the Modal Popup opens up in the background and is disabled...also opens up behind the panel that is in front. I can tell this by repositioning the ModalPopup.

Does this consistently every time.

I removed v15.1.4 and went back to v4 and problem went away.




Comments: I have face same issue in the latest version 15.1.4 where in modal pop up extender is there inside update panel. When we click on button, modal popup is display only once. After subsequent clicks, it seems that modal popup is not displaying on the page. Additionally I figured out that z-index is not set properly and so that modal popup is not displaying. I have tried the approach suggested by __derrellgore__ and installed version 15.1.3. All the issues are resolved automatically. So there is something wrong in the latest version 15.1.4 related to modal popup extender.
