mWieder, the two ways I showed were not wrong, they just weren't as cool as using a user control (I do have videos on adding user controls; I'll have to check on whether I actually went back and did show the popup as a user control. If not, I'll be sure to add that to the list as you are right, I certainly promised to do so.

So you tell us and supply sample code for both "wrong" ways and we get no help doing it the right way?

Where is the sample code? Where is the video you promised?

If you want popups not to crash when you create them in code you need to link them to the parent. Basically add the new pop to the children.

In the below code TestPopupItem is a standard user control.

Popups.TestPopupItem filterWindow = new Popups.TestPopupItem();

this.filterPopup = new Popup();

this.LayoutRoot.Children.Add(this.filterPopup);

this.filterPopup.HorizontalOffset = 80;

this.filterPopup.VerticalOffset = 80;

this.filterPopup.Child = this.filterWindow;

this.filterPopup.IsOpen = true;

Thanks for the example.

The msdn library entry for popup has a note that the popup should be added to the visual tree to prevent runtime errors. I have a couple of questions about that:

Is that still necessary as a workaround? I ask because it isn't shown above.

What do you suggest as best practices for doing this? The example code suggests "LayoutRoot.Children.Add(myPopup);" but that opens up some issues. LayoutRoot might not be the name of the top panel, and if you're implementing a user control it isn't in scope anyway. But you can't always add the popup to the user control because it might have a Border (with one Child rather than Children) as the top level item.

It seems like this complicates the destructor/release step as well - the popup has to be removed from the visual root so it can be garbage collected.

Jesse,

Is there a way to get the absolute x and y positions of another control on-screen? It would be useful to be able to dynamically position a popup directly below its calling control.

This would be one way to create a custom combobox control, using popup to display a listbox of data choices.

It would be quite interesting to see how to extend the popup control, in order to have a base popup template (e.g. a base popup that has by default certain colors, a close button... so you don't have to repeat that boiler plate code on each popup in your application).

This kind of popups are modal, is it possible to configure them to be modeless?

Nice tutorial, ... I was creating this thing manually :).

About partial code...

I uploaded partial code because a user suggested to me that it was painful downlaoding an entire project.

I have now received feedback that my solution is penny wise and pound (dollar?) foolish and I agree. After going through the steps of recreating the project, it is just too painful. So I'll be uploading full projects from now on.

Thanks.
