Preventing the disabling behavior is simple — it’s just part of the visual state animation in the template for the BusyIndicator. You can re-template the control (use Blend to copy the original template) and remove that animation, which will accomplish precisely what you’re looking for.

@Brad Spencer did you get an answer for your question? I have one of the dataform and it leave it disabled just as you explained. If so this is a worthless control if your using RIA. Binding the enabled field on the dataform works like a champ however. Anyone out there?

I’m using the BusyIndicator with RIA Services. It works great except it disables underlying controls even when the indicator doesn’t show. This causes an annoying “flicker” of the page and, even worse, the active control loses focus.

Can I change this behavior and if so, how? Example please.

Thanks for the post!
Is it possible to bind a single Busy Indicator to more than one Domain DataSource?

Excellent post!
I get great experience through your blogs.
Sometimes I get unexpected problems when I working with Silverlight. I want to contact some expert programmer, but I didn’t know anyone. Please, can you let me ask these type question directly (through e-mail).
I want to learn from your experience.

You can actually turn this off quite easily — those behaviors are part of the template for the control (managed by the VisualStateManager). Use Blend to create a new template that doesn’t show the background.

If I remember correctly, though, I don’t put the gray background up immediately — all I’m doing is disabling the underlying controls (which turns most of them gray) by disabling their container. Again, this is behavior you can change easily by retemplating.

Setting IsBusy=true will immediately put up the gray background – even if the actual dialog box hasn’t appeared yet.

This is quite annoying if the component you’re updating is being updated via a timer because it will then flicker on the triggering of the timer.

If the gray background would not appear until the box itself appears then that would be great!

If you’re using busy indicator as a safeguard for a slow internet connection, where normally the call should return instantly this is quite an annoying limitation.

Thanks for reporting this issue! It sounds like a bug in the logic for enabling/disabling when the button is bound to an ICommand. I’ll look into it.
