c# - My WPF ContextMenu is not dismissing when I click elsewhere -

-

i have wpf contextmenu instance declared in xaml this

<window.contextmenu>     <contextmenu>         <menuitem header="do nothing"/>         <separator/>         <menuitem header="{x:static p:resources.menuexit}" click="iconmenu_exit"/>      </contextmenu> </window.contextmenu>

i'm using winforms notifyicon display tray icon this

_notifyicon = new system.windows.forms.notifyicon(); _notifyicon.icon = properties.resources.mainicon; _notifyicon.visible = true; _notifyicon.mouseclick += new system.windows.forms.mouseeventhandler(ontrayiconmouseclick);

the implementation of mouse click handler this

private void ontrayiconmouseclick(object sender, system.windows.forms.mouseeventargs e) {     if (e.button == system.windows.forms.mousebuttons.right)     {         contextmenu.isopen = true;     } }

this displays context menu , clicking on menu items dismisses it, if click away on window, context menu stays visible. seems strange default behavior. there way display context menu other isopen or have explicitly hide context menu somehow?

edit: don't know if matters window's datacontext set this in code-behind.

edit2: context menu dismisses if it's invoked right clicking on actual main window not tray icon.

check have not defined staysopen property true.

SoapUI on windows 10 - high DPI/4K scaling issue -

Image
soapui doesn't seem dpi-aware , displays small on high dpi screen (tiny text , buttons). other applications running fine (screen resolution 3840 x 2160). version : soapui 5.1.2 os : windows 10 i have tried: configure soapui run "disable display scaling on high dpi settings" - parts of soapui looking bigger , don't display (image) changing resolution changing font size (preferences > editor settings > select font...) therefore assume, soapui pretends dpi-aware, not scale itself. have same issue? this workaround until developers round making version dpi-aware. step 1: add registry key hkey_local_machine\software\microsoft\windows\currentversion\sidebyside\preferexternalmanifest (dword) 1 step 2: add manifest file 'soapui-5.2.1.exe.manifest' in same directory 'soapui-5.2.1.exe' content of manifest file: <?xml version="1.0" encoding="utf-8" standalone="yes"?> <assembly xml
