Int to string as hex

I need to display a int as a sting, but i need it to be displayed in hex. This is what i have so far.

this.tbx_result.Text = Convert.ToString(seed);


*EDIT* I figured this part out, but my next problem is i need to figure out how to only allow hex characters to be entered in to the textbox.

To only allow hex characters, use the KeyPress event on the textbox e.g.

Code:

---

private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
    bool isHexDigit =
        Char.IsDigit(e.KeyChar) ||
        (e.KeyChar >= 'a' && e.KeyChar <= 'f') ||
        (e.KeyChar >= 'A' && e.KeyChar <= 'F');
   
    // if not a hex digit, don't continue processing the keypress
    e.Handled = !isHexDigit;
}
