Question : Combobox values default

Hi Am developing windows application where in am loading the combo box as follows

 cmbtitleid.BindingContext = new BindingContext();
            cmbtitleid.DataSource = datasourcetitle;
            cmbtitleid.ValueMember = "TITLEID";
            cmbtitleid.DisplayMember = "DECRIPTION";
            cmbtitleid.SelectedIndex = -1;

Here, what I want to do is, the datasource has only 1 record, then it should be displayed in combobox by default. If there are more than 1 record, then cmbtitleid.SelectedIndex = -1;
should work as is. How do i alter this code to achive what i want

Answer : Combobox values default

almost forgot: if there's a possibility that there's no data returned, do
else if(cmbtitleid.Items.Count == 1)
instead of the else-statement.
