It’s good to see the application of Silverlight in this way. What I like about Silverlight is that it has very rich support for reading data of numerous types from web services to RSS feeds to static XML files. It also has methods to facilitate the deserialization of XML or JSON into strongly types objects for simple manipulation and binding.

I’d recommend filing a bug on the toolkit site. I recently left Microsoft, so I’m not in the best position to relay this information anymore.

Hi,
In the comments I noticed you said this control eventually became the BusyIndicator in the SL 4 toolkit. I’m using the control, and I’ve found some odd behavior. I’m binding IsBusy to a property in my ViewModel, and the content it’s surrounding is in one tab. If i set it to true, then go to another tab, change the IsBusy property to false while the focus is on the second tab, and then go back to the previous tab, the progress indicator is go, but the content is still disabled. If you change tabs and go back again, everything is enabled. Thanks.

The BusyIndicator is a control like any other and follows the same rules for layout. It is simply a ContentControl that covers up its content with the Busy display when IsBusy is true.

Hi!

How can I define the position screen where the BusyIndicator will be displayed??

Thanks!

I certainly haven’t abandoned it — I’m no longer on the Silverlight team itself, but I’m still building things with Silverlight, and intend to continue to post as long as I’ve got new/interesting content. I’ve got another post in the works (code written — just need to document it and write about it), it’s just a question of time.

Greetings I recently finished going through through your blog as well as I’m very impressed. I do have a couple inquiries for you personally however. You think you’re thinking about doing a follow-up submitting about this? Will you be going to keep bringing up-to-date too?
