Controls have a feature called "Conditional Formatting" available from their Properties dialog box. This is what you are looking for.

You will need some way of keeping track of the fact that a control has changed. One way to do this is to create a secondary data source that has boolean values for each control. A rule would be set on each control to set that boolean value to true. The conditional formatting would change the color if the boolean value is true.

This is a lot of work -- especially for a big form, or for a form that isn't "finalized" in its structure and design yet.

There may be other ways, but this is what came to mind first.

Hi,

I would like to know how I can change a control's appearance (color
for example) when its value is changed.

I want to be able to set it for all the controls in my form, so when
someone edit a form it would be clear what was changed in the current
session.

Can I use JScript to implement that?

Thanks,
Liron
