1. Right-click C1GridView and select Show Smart Tag from the context menu.
2. Select Property builder from the C1GridView Tasks menu. The C1GridView Properties dialog box appears.

   Note that you can also remove columns from being displayed by selecting the column in the Selected columns list and clicking the Delete button ("X").
7. Click OK to save your settings and close the C1GridView Properties dialog box.
