wpf - UIElement.Focus() does not work, why? -


my wpf window has button , listview. on button's click event, has following code.

private void mybutton1_click(object sender, routedeventargs e) {     listviewitem lvi = new listviewitem()     {         content = "hello",         focusable = true,         isenabled = true     };     this.listview1.items.add(lvi);     lvi.focus(); }

here problem, focus cannot move lvi(listviewitem), after user clicks button. code lvi.focus() not have effect. can tell me why happens, , how can solve it?

update:

find solution. call code, otherwise focus still captured button.

this.dispatcher.begininvoke(new action(() => lvi.focus()), system.windows.threading.dispatcherpriority.input);

try following:

listviewitem lvi = new listviewitem(); lvi.isselected = true;

hope helps ;)

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
