Hi ueldeep,

By default vertical borders are already not visible.  The only border you should see should be the one between rows, the horizontal borders.  Do you actually mean the reverse?  You want to hide horizontal borders and show vertical ones?

If so you can hide the horizontal borders by setting the row separator height to 0.  igGridView.setRowSeparatorHeight(0)

Getting vertical borders to show up is a bit trickier.  The background color of the grid needs to be set to Black and then the cell background color needs to be set to White.  By default the cell background is Transparent so the grid's background will show through if you don't set it.  The only way I have found to do this though is by creating a custom column definition and overriding the getCell method.  When creating the cell in this method, set the background color to white here.  Once these colors have been set, set the column spacing to 1.  igGridView.setColumnSpacingWidth(1)
