This problem should be simple.

I am using Visual Studio 2003, Version 1.1

I am writing a desktop application in which I am binding a DataTable
to the DataSource of a ComboBox.

//   I have 50 rows (concerning states) in dataTable.Rows;

ComboBox myComboBox = new ComboBox();
myComboBox.DataSource = dataTable;
myComboBox.DisplayMember = "state_name";
myComboBox.ValueMember = "state_id";
myComboBox.SelectedIndex = 3;

I get an exception stating that '3' is out of range, because
myComboBox.Items.Count = 0, not 50.

How can I set SelectedIndex when using a DataSource?

A very messy workaround is to add the items in a loop, but I would
like to use the power of DataSource.

P.S. In ASP.NET they have a DataBind() method which is absent for a
desktop application.

Thanks for your help.
