Question

I have 2 textbox (textbox 1 & textbox 2 ); the textbox1 has numeric value such as $1,000. Now when i am in textbox2 and if i hit keystrokes like (= or + or pageup or pagedown etc…) the textbox1 value should appear in textbox2.

The reason behind this is to enable customers improve speed in processsing/ filling data.

I don’t know if I understand what you need, anyway try this:

private void textBox2_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.PageDown ||
        e.KeyCode == Keys.PageUp ||
        e.KeyCode == Keys.Oemplus ||
        e.KeyCode == Keys.Add ||
        (e.KeyCode == Keys.D0 && e.Shift))
    {
        textBox2.Text = textBox1.Text;
        e.Handled = true;
        e.SuppressKeyPress = true;
    }
}
