I am using AjaxToolkit to have popup for editing image. When I click on Crop or Resize button, the popup for imageeditor shows up behind AjaxToolkit popup. How do I make sure they show up on top?

I am using the latest 2013.2.611.40.

Hello Paul,

The popup extender from the AjaxControlToolkit has a very, very high z-index by default (100001) and this is why it often hides other popups (like RadWindows or the RadDocks RadImageEditor uses). The way to avoid this is by overriding a CSS rule that will change the z-index values for one of the sets of controls, e.g.:

for the ACT modal popup OR for RadDock.

The following article shows the default values for our controls and another way to change their z-indexes: http://www.telerik.com/help/aspnet-ajax/controlling-absolute-positioning-with-zindex.html.
