[WPF] Showing a OpenFileDialog after a MouseDown event with MovableByWindowBackground activated captures all clicks afterward

[borjafdezgauna]

After triggering a MouseDown event on a Panel/Button and showing an OpenFileDialog/SelectFolderDialog, the same event will be triggered no matter where I click. If I use Click it works fine, but there is no Click event for panels I'm afraid

Sample:

   class TestWindow : Form
    {
        public TestWindow()
        {
            MovableByWindowBackground = true;
            var layout = new StackLayout() { Orientation = Orientation.Vertical };
            layout.Items.Add(new Label() { Text = "Label" });
            layout.Items.Add(new TextBox() { Text = "TextBox" });

            Panel button = new Panel() { Size = new Size(100, 100), BackgroundColor = Colors.Red };
            button.MouseDown += ButtonClicked;
            layout.Items.Add(button);
            Content = layout;
        }

        private void ButtonClicked(object sender, MouseEventArgs e)
        {
            OpenFileDialog openFileDialog = new OpenFileDialog();
            openFileDialog.ShowDialog(null);

//If the following line is commented, it throws exception "InvalidaOperationException: Can only call DragMove when primary mouse button is down", otherwise, it captures all clicks from that moment onward
            //e.Handled = true; 
        }
    }

Thanks for reporting the issue!

Just looking at this again, as a workaround if you use the MouseUp event then this shouldn't happen. A "Click" event would also be fired at this time as well.

Than you Curtis!
