GridControl only show scrollbars when needed
Hello,
I'd like to have a GridControl that fills an entire form (using Dock fill).
The GridControl will have two columns: one for input names, and one for values.
The columns widths should be stretched so that the second column fills any extra space if the form is wide.
I also want to have an extra row at the bottom where I set its height to fill any extra vertical space in the form.
I have pasted sample code for my form below, but it is not behaving as I would expect. As I resize the form, the GridControl occasionally shows the vertical or horizontal scrollbar when it should not be shown. I only want to show the horizontal scrollbar if the form width is less than the width of my two columns. Likewise I only want to show the vertical srollbar if my form height is less than the height of my first 10 rows.
Can you please take a look and see why the scrollbars are occasionally appearing when the form is resized?
Also, I'd like to know what I need to do so that the cells cannot be highlighted (for example dragging from the top leftmost cell down and to the right, highlights a bunch of cells).
Thanks for your help.

What the form should look like when there is extra vertical and horizontal space (no scrollbars)
After resizing the form with my sample code, I see both horizontal and vertical scrollbars despite there being extra vertical and horizontal space
