Returns a Range object that represents the range containing all the direct dependents of a cell.

Namespace:  Microsoft.Office.Interop.Excel
Assembly:  Microsoft.Office.Interop.Excel (in Microsoft.Office.Interop.Excel.dll)

Range DirectDependents { get; }

This can be a multiple selection (a union of Range objects) if there’s more than one dependent.

The Direct Dependents property only works on the active sheet and can not trace remote references.
