Always in upper case… (C# winforms)

Question

I have a TextBox in my form and I added this event on it:

private void txtValue_KeyDown(object sender, KeyEventArgs e)
        {
            Me         


        

Answer 1

KeyDown and KeyUp use KeyEventArgs, which exposes the Keys enum via the KeyData property. The enum does not have representation for lower-case alphabetic values.

The KeyPress event allows you to get the actual character of the key pressed via KeyPressEventArgs.KeyChar.

private void txtValue_KeyPress(object sender, KeyPressEventArgs e)
{
    MessageBox.Show(e.KeyChar.ToString());
}
