子コントロールのすべてGotFocus
/イベントを処理する WPF UserControl を作成しました。の/をLostFocus
呼び出しますが、UserControlのプロパティは設定されません。OnGotFocus
OnLostFocus
UserControl
IsFocused
void MyUserControl_Initialized(object sender, EventArgs e)
{
foreach (UIElement control in (Content as Panel).Children)
{
control.LostFocus += control_LostFocus;
control.GotFocus += control_GotFocus;
}
}
void control_GotFocus(object sender, RoutedEventArgs e)
{
if (!IsFocused)
{
e.Handled = false;
OnGotFocus(e);
}
}
void control_LostFocus(object sender, RoutedEventArgs e)
{
bool hasAnythingTheFocus = false;
foreach (UIElement control in (Content as Panel).Children)
{
if (control.IsFocused)
{
hasAnythingTheFocus = true;
}
}
if (!hasAnythingTheFocus)
{
OnLostFocus(e);
}
}
どうすれば設定できますか?
