TCustomRVFormattedData is derived from TCustomRVData.

All classes of RichView objects are derived from TCustomRVFormattedData.

So you can safely typecast any RVData to TCustomRVFormattedData.

As for text deletion - call RichViewEdit1.DeleteSelection.

It deletes selected fragment regardless of its location (assuming that it is

in edited RVData, and it's provided by RVData := RVData.Edit)
