Hey all,

So to start, let me say that I have a project built out to learn with...I'm trying things out just to figure out better patterns and whatnot when building up apps since I've been doing a lot of that lately and I've started a blog to document my experiences.

What I was doing initially was creating a project to figure out which was better to use...a BackgroundWorker or Task for doing background processing of getting a data source for the grid.  What I ended up with was a test app that is buried under a mountain of bad perf and it locks the UI up until it's darn good and ready to let it go.  As far as I can tell in my source code...I'm not attaching any of the BackgroundWorker or Task threads to the UI thread...so I'm pretty confused as to what's going on.

If I just do one at a time, the table starts filling up with data before the RadBusyIndicator can even bring up it's UI...if I try 2 or 3...I start seeing the RadBusyIndicator doing it's thing...but the UI is still responsive.  If I do all 12...the UI is stuck for a good 10 minutes (my test database has more than 250,000 records in each table).

My source files can be found at the following blog post (If you'd rather I posted them here I can do that as well...)

Any thoughts as to what I'm doing wrong?  Thanks in advance.  :)

Hi Toffer,

I reviewed the blog post to which you referred, however, I cannot confirm the exact cause for the UI thread to be blocked. Have you checked the Tips and Tricks and Degraded Performance topics? Generally, all recommendations for improving the performance of the control are listed there.

I hope this helps.

Best Regards,
