here is the situation
my WPF Main window is always visible and several small windows should be floating on the Main Window. So these small windows are children of Main Window and their z-index should be always one greater than Main Window even if the focus is on the main window rather than children but smaller z-index than other applications (e.g. file browser or chrome etc.)
I've tried Window's TopMost property but it makes really top most than everything else even more than application's MessageBox.
any good idea for making these children windows are just floating in front of only parent window?
thanks in advance
