I need a visual indicator on the input controls to show unsaved changes.

Does anyone have an example of altering the background colour, border, or some other part of a control's UI to indicate the user has changed the value since saving?

Thanks,

Ken

Hello Ken,

Try the following approach in order to change the backcolor  after changing the value.

JavaScript:
 
<script type="text/javascript"
    var textBox; 
    function OnValueChanged(sender, args) { 
        textBox = sender; 
        setTimeout("textBox._textBoxElement.style.backgroundColor = 'yellow';", 10); 
    } 
</script> 
[Attach OnValueChanged event to RadTextBox]

This is close, but the background colour doesn't stay.

I need to keep the "changed" appearance until the next save (postback)

Hi Ken,

In order to change the appearance of a RadInput textbox, so that it is preserved, you should modify the control's styles collection:

http://www.telerik.com/help/aspnet-ajax/input_clientsidebasics.html

Apart from EnabledStyle, you can also modify HoveredStyle and FocusedStyle.

SomeStyle[0] is for inline styles, while SomeStyle[1] is for CSS classes.

Kind regards,
