There is a way to prevent the cell's borders from being shown:
thisGrid.DisplayLayout.Override.BorderStyleCell = Infragistics.Win.UIElementBorderStyle.NonethisGrid.DisplayLayout.Override.BorderStyleRow = Infragistics.Win.UIElementBorderStyle.None
However, is there a way to show a column's left/right borders but not show the border between the rows?
HOWTO:How can I make UltraWinGrid display vertical (column) borders without horizontal (row) borders?
Mike, thanks for the information that was very helpful. We were already using a draw filter for removing the dotted lines around the cells and rows (just could not before get it to only do the rows), by setting the Row/Column border styles to None and using the Draw Filter suggested in the code sample at the link Mike suggested above we got the desire results.
Thanks again.
