The SalesLogix GridView control does not offer settings fro controlling the width of columns placed within it during design time.  Apparently, the though was the control does such a fine job of auto-sizing the grid that exposing those kind of properties was not needed (It is).  There is a way of doing this, though it must be set at run time via code.

If you are using a quickform, you can add code to the Load event similar to this:

myGrid.Columns[0].ItemStyle.Width = 80;

Keep in mind “myGrid” is the name of the GridView control.  the “[0]” refers to the column in the grid you wish to adjust.  The column collection is zero based, meaning that the first column on the left would be [0], the second would be [1], and so on.  Also keep in mind that if you introduce a new column to the grid at some point the column index specified in code like this may no longer be valid.
