New border style not applied to columns in header row?

[Andy Kay]

I'm setting a new border style for certain columns in my virtual grid. To do so, I'm handling GridQueryCellInfo and when the row is (-1) I assign the new border styles. The problem is that the border styles are not applied to the columns of the header rows.

The e.ColIndex == -1 sets the rowstyle for the e.RowIndex row. This rowstyle does not affect the row headers (column 0) as you noted. So, to catch the row headers in addition to the rowstyle, you could look for e.ColIndex <= 0 instead strictly equal -1.

That did the trick. Thanks again.
