xaml - Detect mouse left button down (Click) outside a border WPF MVVM -


i have border in mvvm. trying achieve detect mouse left button down outside border , hide it. can within mouseleftbuttondown event main window, not know if best solution. how this? want avoid click interfere other events, example, border placed in stackpanel , stackpanel being hidden on mouse left button double click.

<border grid.row="2"       x:name="custompopup"       cornerradius="10,10,0,0"       height="25" margin="0"      horizontalalignment="center"       verticalalignment="center"      width="auto"      borderbrush="darkblue"       borderthickness="1"        background="antiquewhite">     <stackpanel  orientation="horizontal"                   horizontalalignment="center">         <image source="/common.images;component/images/info.png"                 height="20"                 width="20" stretch="fill"/>         <textblock margin="5"                     verticalalignment="center"                     horizontalalignment="left"                     background="transparent"                     fontsize="12">                   <run text="click outside close it"/>         </textblock>     </stackpanel> </border>

using mousedown on window best bet desired results. you'll need calculations in order see if cursor outside of border. like:

private void window_mousedown(object sender, mousebuttoneventargs e) {     // positions     point mouseloc = mouse.getposition(null);     point borderloc = custompopup.translatepoint(new point(0,0), null);      // check if mouse outside border     if((mouseloc.x < borderloc.x || mouseloc.x > (borderloc.x + custompopup.actualwidth)) && (mouseloc.y < borderloc.y || mouseloc.y > borderloc.y + custompopup.actualheight))     {         // hide border     } }

then handle double click, use previewmousedoubleclick. since preview events tunneling rather bubbling, double click should called if have single click event on same element.

private void window_previewmousedoubleclick(object sender, mousebuttoneventargs e) {      // double click code...      e.handled = true; }
