You can create your tip as a window and show it using ShowDialog(). This gives you a Modal dialog, as others have suggested. Be sure to set it's owner. Just before you show it, you can use

to set your window or outer container's(grid maybe) Blur Effect. The radius property sets the "level" of blur, so I imagine you can set it to 0 initially and modify it programatically when you show your dialog
