C# Right mouse click on button does not raise mouseclick event

问题

I have a button on a form and want to handle both left and right clicks.

I am handling the MouseClick event, but this is only raised on a left click.

Is this a problem somewhere in my code (a setting that I have missed) or the intended functionality?

If this is not possible to fix, what is the best workaround - to handle the MouseUp event?

The reason I would like to use MouseClick is so that double clicks are automatically recognised.

Thanks for any feedback.

Use MouseUp !!

    private void button6_MouseUp(object sender, MouseEventArgs e)
    {
        if (e.Button == System.Windows.Forms.MouseButtons.Left)
        {
            MessageBox.Show("LEFT");
        }
        if (e.Button == System.Windows.Forms.MouseButtons.Right)
        {
            MessageBox.Show("RIGHT");
        }
    }

Its hard to answer without code but in general, it should work.

 private void Form1_MouseClick(object sender, MouseEventArgs e)
{
  if (e.Button == System.Windows.Forms.MouseButtons.Left)
  {
    MessageBox.Show("LEFT");
  }
  if (e.Button == System.Windows.Forms.MouseButtons.Right)
  {
    MessageBox.Show("RIGHT");
  }
}

// EventHandler

 this.MouseClick += new System.Windows.Forms.MouseEventHandler(this.Form1_MouseClick);

Edit: There is a MouseDoubleClick Event you might want to use to recognize double clicks. Works both, for left and right musebuttons.

Apparently the answer to this is that OnClick does not handle right click events for Buttons. The solution was therefore to use MouseUp/MouseDown and check for double clicks/clicks where the mouse moves on/off halfway through manually.
