Default/Null vale for pulldown populated by query?

[NicktheNewbie]

I have a dropdownlist with values that are populated by a sql query.

Can I have there be a --Please Select Value-- option, which, if none is selected, results in a null selection?

For instance: The DDL populates with
A
B
C

And I would like it to first have:
--Please Select Value--
A
B
C

Again, if no value is selected, it should be null.

Is this something I can set with the properties of the form, or would my query need to have this in it somewhere?

The line below will place this on top of the ddl.

ddlName.Items.Insert(0, new ListItem("--Please Select A Value-- "));

You could check the ddlName.SelectedIndex and if it is equal to zero act accordingly.
