How to set rowheight on AXGridView row in EP

I am trying to figure out how to set the RowHeight under the AXGridView RowStyle.  I set the property but it doesn't seem to work.  I added a memo field to the grid but I don't want the grid to increase the height enought to display the entire field.

Thanks.
