If you look at
this page[
^] on MSDN and examinr the code, you will find this:
<asp:BoundField HeaderText="Price/Unit"
DataField="UnitPrice" SortExpression="UnitPrice"
DataFormatString="{0:c}">
that code formats the data for the 'Unit Price' column.
Unsurprisingly you can do a similar thing for Dates as well as for Currency.
On
this page[
^] you will find the various Format Characters and the second table lists those for date values. The first one is the one you would need.
