You can resize the RadBusyIndicator control in Expression Blend. A few steps you need to follow:
- Generate the Template of RadBusyIndicator
(right-click > Edit Template > Edit a Copy)
- In the template find the ProgressBar
- Edit the current template of the ProgressBar (right-click > Edit Template > Edit Current)
- There are three elements inside that template that need to be manually resized: IndeterminateBackgroundDonut
For your convenience, I have attached a sample of the this resizing process. You might also consider changing the Visibility of ProgressBarTrack to Collapsed, because 20px/20px is too small a size to accomodate nicely all three elements.
I hope this helps.
All the best,
the Telerik team
