On the left side of the grid, there's this left most area with the pen icon in it. I don't know what's called so I don't know how to search the docs for it. How can it be disabled?
That did it. Thanks.
Those are the row selectors (I think). You can make them disappear completely like this:
ultraGrid1.DisplayLayout.Override.RowSelectors = DefaultableBoolean.False;
ultraGrid1.DisplayLayout.Override.RowSelectorHeaderStyle = RowSelectorHeaderStyle.None;
