TextSize and TextFont return invalid values

I am trying to implement a printing routine and need to get the Heading and Cell text font and text size for a DataView grid object. It appears the TextFont is always an empty string and TextSize is always zero.

For the header I have tried:
.Column( iCol ).HeadingTextFont
.Column( iCol ).HeadingTextSize

for the Cell I have tried:
.CellTextFont(iRow, iCol)
.CellTextSize(iRow, iCol)

I have also tried
.Column(iCol).TextFont
.Column(iCol).TextSize

and
.TextFont
.TextSize

The font is always an empty string
and the text size is always 0.

I am sure I am missing something simple...

How should I determine the currently used text font and text size for column headings and cells?
