ViewModel Usage

It is possible to do Find/Replace without the RapidFindReplace controls - instead the control's ViewModel class (RapidFindReplaceControlViewModel) may be used directly.

A TextBox is bound to the Query DependencyProperty in RapidFindReplaceControlViewModel, a KeyUp handler is used to trigger as-you-type finds and the Button fires the FindTextCommand in the view model.

This style of usage allows lower level access and the opportunity to build a Find/Replace UI from scratch. The RapidFindReplaceControlViewModel declaration below also sets some brush style properties by way of example.
