Popup TopMost.

[FoxTes]

Hello. Tell me please. Can I forcefully prevent the window to be closed (popup). I need an analogue of TopMost.

It appears as there is another application that knocks the focus of this window.

Thanks for the support.

I'm a bit lost what you like from this repository.
What popup are you talking about, can you be more specific?

[FoxTes]

I'm talking about TaskbarIcon. I'm sorry I misled you.

Is it possible to prohibit its closure? I need TrayPopup to always be open.

I know that you talk about the Taskbar Icon 😉
But I do not know how you use it, you might want to describe your issue with more details.

So far you are describing the default behavior of a Popop.
If you show a custom balloon, the "StaysOpen" is set to true, so I am not sure what you actually did.

Can you supply a code snippet?

Good. Let's start from the beginning. Here is my code:

<tb:TaskbarIcon
     IconSource="/Resources/trayIcon.ico"
     MenuActivation="RightClick"
     PopupActivation="LeftClick"
     x:Name="TaskbarIcon">

     <tb:TaskbarIcon.TrayPopup>
         <reactiveUi:ViewModelViewHost x:Name="ViewModelViewHost" />
     </tb:TaskbarIcon.TrayPopup>
</tb:TaskbarIcon>

In the view model, I have a button that starts the application installation. The installer of the program is not hidden, so the activated Popup is closed. I want to prevent this. Now I am forcibly opening Popup again manually.

PS. It's not about balloon.
