How to prevent parent window from going into background after child is closed?

Question

So, I've been running into a problem with many of my WPF applications where after closing children windows of a window, that window (usually my main window) will go into background, behind anything else I have open. After some research, I found this bug report submitted to Microsoft: Bug Report and their usual response of "The WPF team has recently reviewed this issue and will not be addressing it..." Has anyone been successful at tackling this on their own? It drives me mad and I can't figure out a solution. EDIT: I gave some thought to what James had recommended in his answer and after almost dismissing his suggestion due to the inconvenient nature of the window being on top of everything else, I came up with this: ``` ChildWindow.Closed += delegate { ChildWindow = null; this.Topmost = true; System.Threading.Thread.Sleep(1000); this.Topmost = false; }; ``` So, when child's `Closed()` event is raised, I make sure that the parent window is the topmost. Then, I let the thread sleep for…

Accepted Answer

set the Main window to:

```
Topmost=true
```

This should help a little, but will not solve the issue entirely. Just keep in mind that if another application has the setting, they could end up on top of the application anyways. Let me know if this helps.
