Formatting a GridView Column to show currency
Assuming you already have a GridView column from an Access database named, for
example, "Price" that is just showing up as 433.50 and you want it to show up as
$433.50, follow these steps:
1. In your Access database the Price format should be selected as a number of
type currency.
2. In the GridView, expand the little arrow on the upper right, select Edit
Columns, and highlight the Price column
3. In the Behavior section set htmlencode to False
4. In the Data section, for the DataFormatString type: {0:C}
5. Click OK, save, Preview in Browser
That should result in the data showing up like $433.50
