There are a lot ways to set the default value for a dropdownlist when it has been databinded in an ASP.NET Page. I will list some of them and point out the pros and cons.

Way #1 (recommended way):

Protected Sub dropdownExample_DataBound(ByVal sender As Object,
ByVal e As System.EventArgs) Handles dropdownExample.DataBound
‘set the default value for the drop down

Me.dropdownExample.SelectedIndex = Me.dropdownExample.Items.IndexOf ( Me.dropdownExample.Items.FindByValue ( ‘The Default Value’ ) )
End Sub
