The following part of the ASPxCaptcha - Custom Appearance online demo illustrates how to implement a captcha control with a custom appearance.

In this example, the control’s Refresh Button.ASPxCaptcha and Text Box.ASPxCaptcha are hidden, and their functionaliry is implemented in a custom manner using separate controls (the IMG element, ASPxLabel, ASPxTextBox).

function GetRefreshButton() {
    return document.getElementById("refreshButton");

function OnCaptchaBeginCallback(s, e) {
    var refreshButton = GetRefreshButton();
    refreshButton.src = "Images/refreshButtonAnimated.gif";

function OnCaptchaEndCallback(s, e) {
    var refreshButton = GetRefreshButton();
    refreshButton.src = "Images/refreshButton.gif";
