How to spin an independent dispacher thread for a Silverlight UserControl

I am trying to move a lot of different elements by 1 pixel very often and in parallel. Trying to do this on one dispatcher thread means that the elements are visited one after another. The result is that the more elements I have the slower they will all move.

In WPF I was able to use a HostVisual as described here to solve this.

I can't seem to find anything similar in Silverlight. Is this a drawback of the lightweight framework or is there something I haven't stumbled upon yet?

I am using SL4.

Solution

  • Silverlight only has the single user interface (primary dispatcher) thread. So yes, a drawback of the lightweight framework.

    Consider if you could batch up work that you do using a BackgroundWorker, so that you can do any and all non-visual work on another thread.
