Issue with updating background color of a RadTextBox via JavaScript

[Robert]

Hi,

I need to implement a password strength indicator. To indicate the password's quality I want the password input text box to change it's background color from red to green when the user enters a character.

Since the RadTextBox's client-event "OnKeyPress" is not thrown on delete keys, I use

"onKeyUp" here is my JavaScript function which shall set the background color to red

(just for debugging purposes):

 function checkPassword() {
            var passwdBox = $find("<%= PasswordBox.ClientID %>");

            passwdBox.get_styles().EnabledStyle[0] += "background-color: Red;";
            passwdBox.updateCssClass();
        }

The problem is, that the color simply does not change. What's wrong with my code?

Best regards,

Robert
