Unwanted white lines

    In attached file UnitSettingsFill.png there are 2 unwanted white lines.  To the right of the spreadhsheet control is a thick vertical line that runs the full height of the spreadshee.  Hanging off the lower left corner of the spreadsheet is a short, vertical white line.  The relevant bit of the code for creating this image is

    <span>grid = new PropertyGridControl();</span>
    <span>grid</span><span>.Dock = DockStyle.Fill;

    </span>File UnitSettings.png was created without a <span>grid</span><span>.Dock </span>specification.   Since it also has the unwanted white lines, I assume the lines are controlled by the style/painting/... of the spreadsheet.  What need I change in my code to make the lines go away?

    It looks like you have the spreadsheet control's BorderStyle property set to Fixed3D (which is the default setting).  The FpSpread class inherits the BorderStyle property from the Control class.  When BorderStyle = Fixed3D, the Control class draws a 3D border around the outside of the control.  You can set BorderStyle = None to remove the 3D border.

        fpSpread1.BorderStyle = BorderStyle.None;

    BorderStyle doesn't seem to be what's wrong.  The default (inherited?) value in my app is BorderStyle.None.  I've tried all 3 border styles (None, FixedSingle, and Fixed3D) and, sad to say, the appearance remains the same.

    Any additional thoughts?

    I don't know if this helps, but it looks to me like it might have something to do with reserved space for vertical and horizontal scroll bars. Is there a setting something along the lines of VerticalScrollBar.Never and HorizontalScrollBar.Never that may apply here?

    To me this looks like the border of the Panel control and not the Spread. If this is not the issue, could you post a small zipped project reproducing the issue for us to debug?

    Since the right-side white line is the same distance from the grid, it would seem to be associated with the grid, rather than the panel.  I'll see if I can create a small project that demonstrates the problem, though I won't be able to do that until Monday.
