The zero-based position in the formatted string where the search starts.
- endPosition
- Int32
The zero-based position in the formatted string where the search ends.

If successful, an Int32 representing the zero-based position of the first unassigned editable position encountered; otherwise InvalidIndex.
Remarks
The formatted string is composed of editable characters and literals copied from the mask. The editable character positions will either be occupied by the prompt character copied from the mask if they are unassigned, or with a valid input character if they have been assigned an input.
The FindUnassignedEditPositionInRange method is used to search for the first unassigned character between two specified positions, inclusive, using the specified search direction. The prompt character should occupy this position.
The FindNonEditPositionInRange and FindAssignedEditPositionInRange methods are complements of this method.
