i want send mouse click application behind control. have topmost transparent window , controls in it. able send click through of controls.

i have tried setting property ishittestvisible="false" control, doesn´t work. doesn´t send click through control desktop example.

i´ve tried solution proposed in question: how create semi transparent window in wpf allows mouse events pass through

and works, make transparent controls, not window.

how apply solution question single control, example ellipse?

the solution:

public static class windowsservices {   const int ws_ex_transparent = 0x00000020;   const int gwl_exstyle = (-20);    [dllimport("user32.dll")]   static extern int getwindowlong(intptr hwnd, int index);    [dllimport("user32.dll")]   static extern int setwindowlong(intptr hwnd, int index, int newstyle);    public static void setwindowextransparent(intptr hwnd)   {     var extendedstyle = getwindowlong(hwnd, gwl_exstyle);     setwindowlong(hwnd, gwl_exstyle, extendedstyle | ws_ex_transparent);   } }  protected override void onsourceinitialized(eventargs e) {   base.onsourceinitialized(e);   var hwnd = new windowinterophelper(this).handle;   windowsservices.setwindowextransparent(hwnd); }
