PopupBox in modal mode?

[DrCQ]

I'm using PopupBox to open a dialog (UserControl) written with MVVM patterns. The StaysOpen property is set to True, but any click outside the PopupBox content is closing my dialog, The same happens when I try to examine the dialog properties using Blend. Click on the PopupBox in the Blend application is also closing the PopupBox content. It is possible to set the PopupBox in the modal mode?

This is probably a bit of a poor name for StaysOpen on PopupBox. The PopupBox control is designed to be a simple wrapper around a toggle button and a popup control. Unfortunately, the StaysOpen property means that the popup should stay open even after the user interacts with it, it is not the same as the Popup.StaysOpen property. Effectively this control is meant for short quick interactions, not longer, dialog-style implementations.

Unfortunately, there are only a few options I can think of:

• Switch to using the DialogHost control this one also uses a Popup but it is quite a bit different so might not mean your UX.
• Roll your own implementation with a Popup and ToggleButton controls. Since PopupBox is just a thin wrapper around these controls it would let you have more control over the behavior.
