Mybe but can it be used in VBA?
I found a solution but its kind of lengthy:
RowRange = chkBox.TopLeftCell.Address(RowAbsolute:=False, _
ColumnAbsolute:=False)
I am thinking this will return a relative address. Here is what the help has to say:
Range object (Syntax 2): Returns the range reference in the language of the macro. Read-only String.
Syntax 1
expression.Address
Syntax 2
expression.Address(RowAbsolute, ColumnAbsolute, ReferenceStyle, External, RelativeTo)
expression Required. An expression that returns a Hyperlink object (Syntax 1) or a Range object (Syntax 2).
RowAbsolute Optional Variant. True to return the row part of the reference as an absolute reference. The default value is True.
ColumnAbsolute Optional Variant. True to return the column part of the reference as an absolute reference. The default value is True.
ReferenceStyle Optional Variant. Can be one of the following XlReferenceStyle constants: xlA1 or xlR1C1. Use xlA1 to return an A1-style reference. Use xlR1C1 to return an R1C1-style reference. The default value is xlA1
External Optional Variant. True to return an external reference. False to return a local reference. The default value is False.
RelativeTo Optional Variant. If RowAbsolute and ColumnAbsolute are False, and ReferenceStyle is xlR1C1, you must include a starting point for the relative reference. This argument is a Range object that defines the starting point.
Remarks
If the reference contains more than one cell, RowAbsolute and ColumnAbsolute apply to all rows and columns.
