C#

private void textBox1_TextChanged(object sender, TextChangedEventArgs e)
        {
           string str = textBox1.Text;
           textBox1.Text = str.ToUpper();
        }

don't use text change event instead simply use Charactercasing property

Wel if it is not necessary to use event then simply go to properties of your text box and change CharacterCasing to Upper, now all input will be in upper case.

Solution 1

You have to set the cursor position to the end of the text like this:

C#

void textBox1_TextChanged(object sender, EventArgs e)
{
    textBox1.Text = textBox1.Text.ToUpper();
    textBox1.Select(textBox1.Text.Length, 0);
}

cheers
