Always uppercase ... (C # winforms)

Question

I have TextBoxin my form, and I added this event to it:

private void txtValue_KeyDown(object sender, KeyEventArgs e)
        {
            MessageBox.Show(e.KeyData.ToString());
        }

But he always types uppercase letters, although I entered a lowercase letter in the text box. See image below:

How do I get the correct display? Thank...

Answer 1

KeyDownand KeyUpuse KeyEventArgsthat provides an enumeration Keysthrough the property KeyData. The enumeration has no representation for lowercase alphabetic values.

The event KeyPressallows you to get the actual character of the key pressed through KeyPressEventArgs.KeyChar.

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