Question

Code in User Control (Windows User Control).

I have a button and when click on the button some logic will fire.

below is button event.

 private void btnCancel_Click(object sender, EventArgs e)
 {
     // Some Logic
 }

I have Main form (Windows form)

I am adding the above user control in a Panel of my Main Winform.

From here I want to invoke the user control btnCancel_Click event using some function Keys Like (F3,F4).

This is a very new thing for me. Please help me in this regard.

Thanks .

Set your parent form KeyPreview attribute to true and then in the KeyDown event of your parent form, look for if(e.KeyCode == Keys.F3), then write a public method for your usercontrol which fires the btnCancel_Click. You can access it from your parent form.

Parent Form:

private void Form1_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.F3)
    {
        MyUserControl.FireButtonEvent();
    }
}

Usercontrol:

public void FireButtonEvent()
{
  this.btnCancel_Click(null, EventArgs.Empty);
}
