The following part of the ASPxCaptcha - Features online demo illustrates how to customize the characters set used to generate the challenge image’s code (ASPxCaptcha.CharacterSet) and specify this code length (ASPxCaptcha.CodeLength).

This settings are specified within a panel (ASPxTextBox, ASPxSpinEdit editors) and applied to the captcha control via the Apply button (ASPxButton).

protected void btnApply_Click(object sender, EventArgs e) {
...
    int parseResult = 0;
    if(tbCharacterSet.IsValid)
        Captcha.CharacterSet = tbCharacterSet.Text;
    if (int.TryParse(seCodeLength.Text, out parseResult))
        Captcha.CodeLength = parseResult;
...
}
