Synchronize RadComboBoxes

[JSON]

I have two RadComboBoxes, one to select a primary value using load on demand and the other to select a secondary value. When a value is selected in the primary control, I need to bind the secondary control with value relative to the primary selected value. (parent / child)

I know this can be accomplished using AJAX, but I could use an example of how to do this.

Thank you
