Hello,

When draggable element is inside Window widget, then it drags before the window for first 3 times only. Starting from 4th drag-and-drop operation, it drags behind the Window widget. Have a look at the sample code:

<body>
    <div id="windowTest" >
        <div id="divToDrag" style="width:50px;height:50px;background:yellow;" ></div>
    </div>
 
    <script>
        $(document).ready(function () {          
            $("#windowTest").kendoWindow({
                width: "200px",
                height: "100px"
            });
 
            $("#divToDrag").kendoDraggable({
                hint: function (element) {
                    return element.clone();
                }
            });
        });
    </script>
</body>


The problem cause is the following: the dragging element z-index is 10010, but the Window z-index increases from 10003 by 2 every time the drag started. So, for the first drag-and-drop operations, the Window z-index is 10005, 10007, 1009. For the 4th drag-and-drop the z-index became 10011, and the dragging element drags behind the Window.

Can you please suggest me how to fix this problem?

Thanks,
  Sergey

Hello Sergey,

The problem with the ever-rising window z-index has been fixed in the latest internal build.

I am experiencing a similar issue.  I have several windows on the same one page app and as I open and close one and then open the other the z-index climbs.  The problem is that we use a rad drop down and the drop down portion's z-index does not change.  after about 20 opens the z-index of the window climbs past the z-index of the drop down then the drop down is hidden.  

I cannot post code as it is too large but I can give a demo as our software is online.  https://https://onlinestage.greatergiving.com/ username: apdemo.telerikdemo, password: Password123.  Click the Go Time link and click on Checkin Attendee button.  Pick any name from the dropdown and click Next.  Click the Sell New button and inspect the z-index of that window, it should be 10005.  then click cancel and click Use Existing, that z-index will be 10007.  Click cancel again and go back to Sell New and that z-index will be 10009.  this app gets used heavily without closing so after a while the dropdowns in the window end up behind the window.

Hello Kurt,

I could not log in to the site. However, the issue can be resolved by adding a handler for the activate event of the window, and updating the z-index of the drop-down list via jQuery:

activate: function() {
    // update z-index of the drop-downs here
}
