Format DataSource Data

I have an SQL database with a number of fields, one of which is for storing the date (datetime).
When I insert data into the table, I only supply the date because I don't want or need the time to be listed. However, when I execute a query, the data that shows up in my gridview is (e.g) 13/10/2007 12:00:00 AM.

What I want ti know is, how can I format the datetime when I run the query so that it only shows 13/10/2007?
This is how I'm retrieving the data at the moment:

SqlCommand command = new SqlCommand("SELECT * FROM tblMail", sqlConn);
conn.Open()
SqlDataReader reader = command.ExecuteReader();
dataGrid.DataSource = reader;
dataGrid.DataBind();
conn.close()

In my dataGrid, I have a number of fields that are bound to the data source, such as Date, Name, Address etc etc
Anyway, any ideas on how I can format the SQL DateTime so it only shows the date in my datagrid?
