I don't understand when you say
"i want my button click event should fire and also application should not gain the focus"
If you can click on the button, the application gains the focus, otherwise you would click through the button/application and the click would be received by the app underneath...

Hi

We want "Click Me" button should look as non transparent(as normal button) and other area should be transparent in your sample which you provided.
Please help us to achieve this.

HI.

The problem is that all child windows of a transparent window are transparent
So the window containing the XAML button (class "Microsoft.UI.Content.ContentWindowSiteBridge") must not be a child
This can be changed with APIs like SetParent, but I did some tests and then it becomes too complicated to handle correctly all mouse messages and focus...
