In WPF / C#, how can I check if the center button is clicked or released?

Question

In WPF / C#, there are events on MouseRightButtonDown and MouseLeftButtonDown, but what about the center mouse button?

Is the Center Mouse button down/up e.g. events in WPF forgotten?

How can I check if the center button is clicked or released?

Answer 1

Use the MouseDown/MouseUp event and check the MouseButtonEventArgs:

private void control_MouseDown(object sender, MouseButtonEventArgs e)
{
    if (e.ChangedButton == MouseButton.Middle)
    {

    }
}

Answer 2

Use the MouseDown and MouseUp events:

You should use the MouseDown event and check the MiddleButton state in the event arguments.

Answer 3

you can handle MouseDown event and in event handler you can check which Mouse Button was pressed by using

if(e.ChangedButton == System.Windows.Input.MouseButton.Middle)
{
.....
}

Answer 4

I do not think there is a direct event handler defined for Up or Down events. The only thing we could do is handle the MouseDown event and check the MiddleButton state like so,

void Window1_MouseDown(object sender, MouseButtonEventArgs e)
    {
        MessageBox.Show(e.MiddleButton.ToString());
    }
