#869 – Don’t Leave a Popup Window Open
July 23, 2013 1 Comment
You can leave a Popup window open while the user interacts with other controls in your application by leaving the StaysOpen property set to true.
You wouldn’t typically do this, however, because this leads to behavior that is a bit odd and not typical. The popup window will always be on top of the main application window, so it blocks any portion of the application that ends up under the popup. If the user has moved the main window, the popup may end up located somewhere that isn’t close to the main window and it may not be obvious what application it belongs to.
If you do want the popup to remain visible until the user explicitly asks to hide it, you should:
- Include some indication, like a title, that indicates the parent application
- Provide a control, like an OK button, that allows the user to explicitly hide the popup
