WebTextEditor1.TextMode = TextBoxMode.Password
WebTextEditor™ can easily be set to password mode so that other people standing by will not be able to see what your end user is typing into the editor.
To use WebTextEditor in password mode you must set the control’s TextMode property to Password. You can set the TextMode property to Password either by using the Microsoft® Visual Studio® Property Window or by using the following code:
In Visual Basic:
WebTextEditor1.TextMode = TextBoxMode.Password
In C#:
WebTextEditor1.TextMode = TextBoxMode.Password;
