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.ItemStyle.Width = 80;
Keep in mind “myGrid” is the name of the GridView control. the “” 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 , the second would be , 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.
