The properties dialog appears on the right-hand side of the screen. It allows you to set the properties for individual columns.
To make changes to a column's properties, simply click on a property in the right-hand dialog. The property name will be highlighted. The following properties are available:
Header - The text that will be displayed above the column in the grid.
Width - The width of the column in pixels. This is only used for Comment columns and will serve to limit the Comment text displayed in the grid.
Related Field - The field that the column is mapped to. This is a read-only field.
Place your cursor in the field to the right of the property name. You can then type directly in that field.
