For this example, we will resize the Group Header section and fields as well as format a field value. To do this, complete the following steps:

1. To resize the Group Header section, select its border and with your mouse pointer drag to the position where you want it.

   

2. With your mouse pointer, drag field corners to resize fields.

   

   Tip: If text is not fitting in the field, set the Appearance.WordWrap property for the field to True in the Properties window.
3. In the Properties window, select the UnitPriceCtl field in Detail section under the Unit Price column.
4. Set the Appearance.Format property for the field to Currency.
