Question

I create the btn1_MouseDown event handler:

private void btn1_MouseDown(object sender, MouseEventArgs e)
{
    btn1.BackgroundImage = Properties.Resources.click;
}

I want to disable that btn1_MouseDown event behind this RadioButton when it is checked. I mean to say when RadioButton is checked then this btn1_MouseDown event should not work.

private void r1_CheckedChanged(object sender, EventArgs e)
{
    if (r1.Checked == true)
        clock = 5;

    radioButton2.Enabled = false;
    radioButton3.Enabled = false;
    radioButton4.Enabled = false;     
}

Is that possible?

Answer 1

inside r1_checkeChanged add:

btn1.MouseDown -=btn1_MouseDown;
