Question

I have this requirement that the users need to use the keyboard numpad keys to control specific button assigned to it and perform each function.

Example:

if Numpad key 0 is press then Button0 will be triggered.

Or

if(Numpad0 is pressed)
{
 //do stuff
  if (inputStatus)
        {
            txtInput.Text += btn0.Text;
        }
        else
        {
            txtInput.Text = btn0.Text;
            inputStatus = true;
        }
}
else if(Numpad1 is pressed)
{
//do stuff
}

In my form i have a split container then all Buttons are located on a group box.

By using ProcessCmdkey Solves the Problem:

 protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
        {       
           if (keyData == Keys.Numpad0)
                {
                    Numpad0.PerformClick();
                    return true;
                }

            return base.ProcessCmdKey(ref msg, keyData);
        }

Thanks
