[Solved] Bug (?): Popup inside RadWindow

[hwsoderlund]

Here's the situation (pseudo xaml):

<RadWindow>
    [A bunch of stuff here]
    <Popup>
        <Canvas>
            <RadMenu></RadMenu>
        </Canvas>
    </Popup>
</RadWindow>

I'm trying to simulate a context menu here. The idea is to set IsOpen to true on the popup when a row in a data grid is clicked, and then position the menu in relation to the canvas. Then when the Canvas is clicked I hide the popup. But after upgrading to version Q2 the entire popup appears behind the parent RadWindow. In the previous version this was not a problem. I'm guessing that this has something to do with the new layout model that you've introduced for the window component.

I just read this post. Please ignore this.

It turns out that this is not so easily solved after all. I've struggled with the RadPopup now for a couple of hours. I finally succeeded in displaying my context menu, but the positioning is wrong the first time I show it. When I close it and show it a second time the positioning is correct. I've attached the radpopup to a datagrid with the LogicalParent property: ( MyRadPopup.LogicalParent = MyDataGrid; ). That was the only way I could make the popup content display at all. The first time I show the popup it positions itself on the exact same position as the grid, which is not what I want. I want it in the top left corner of the browser window, like a normal Popup control. The weird thing is that when I close the popup and show it again, the positioning is correct. Is there a way to force the correct positioning on the first showing? And when will we see documentation and examples for the RadPopup control?

Hi Henrik,

With the latest update, we introduced a PopupManager that handles Z-Index on all popups (RadWindow, RadWindows with TopMost=true, and RadPopup - used in combobox, menuitem, datepicker, timepicker).

The PopupManager exposes four zones: Window, TopWindow, Popup and DockWindow (for future use).
If you want your popup (not RadPopup) to show on top you can set its Child Z-Index to be bigger then 300,000 (this is the starting Z-Index for Popup zone).

I recommend that you use Popup control instead of RadPopup because RadPopup used to be a workaround for a bug in the Silverlight 2 platform and we might drop it from the future versions.

As for the ContextMenu - we will most probably have it for the Q3 release.

We apologize for any inconvenience we might have caused you.

If you have other questions, drop us a line.
