Hi Konstantin,

I, too, have this problem and have to admit that the solution in Service Pack 2 was not quite what I'd hoped for.

We put messages in our input boxes to help guide people for input. For example, "Password is required", etc. When I put that Empty Message into a RadTextBox with Textmode on Password, I just get ******************* in the box. I have re-created this on your website at the following web address (in IE7):

Please let me know if there is some sort of work around where I can display the message so a person can read it.

Thank you,
David

Hi David,

The initial issue in this thread was a bit different and is already addressed as promised.

Your request however requires changing of the input's type attribute on the client, which is not allowed by the browsers. That said, I'm afraid there is no input control which provides such behavior.

On a side note, the "Password is required" looks like a validation error you want to display. You can use RequiredFieldValidator for this purpose:

Hi Briankb,

I'm afraid there is a misunderstanding here.

The initial problem in this thread, which I mentioned as resolved is that the when the EmptyMessage was set in the RadTextBox in Password mode, nothing was displayed. This is addressed with the previous release.

As I tried to explain later however, you cannot display any text (including EmptyMessage) in a password input mode. This is a browser restriction which we cannot work-around. The input type should be set to text to be able to display some text in the input (which is achieved in RadTextBox by setting the TextMode as "SingleLine" or "MultiLine" and not to "Password"). The "password" type causes the browser to display any text one sets in the well known password mode.

I hope this clears the confusion.

Best wishes,

It'd be quite easy to work around, actually. Many control libraries (Telerik RadControls for ASP.NET AJAX included) back a single control with muliple browser elements. The way to do this would be to have a plain text input displaying the empty message, and then, on focus, hide that element, present the password element, and focus that element.

This is actually a rather serious api consistency break, and I'd like to see it addressed in a near release.

Edit: In fact, in five minutes, I put together the following example. Looking at the code rendered already by a RadTextBox, it's not difficult at all to see it rendering something similar to this given textmode=password.

<html>

<head>

<title>test</title>

</head>

<body>

<input id="passText" type="text" value="foo bar" onfocus="passOnFocus()" />

<input id="passPass" type="password" value="" style="display: none" onblur="passOnBlur()" />

<script type="text/javascript">

var txt = document.getElementById('passText');

var pas = document.getElementById('passPass');

function passOnFocus() {

txt.style.display = 'none';

pas.style.display = 'inline';

pas.focus();

}

function passOnBlur() {

if(pas.value == '') {

pas.style.display = 'none';

txt.style.display = 'inline';

}

</script>

</body>

</html>
