How to programmatically set SelectedValue of Dropdownlist when it is bound to XmlDataSource

Question

I m using XmlDataSource as the datasource for a dropdownlist   Now I want to set the SelectedValue of the drop down when the page initially loads  I have tried the OnDataBound event of the drop down in which I could see the total items  But setting the SelectedValue didn t work  InOnDataBinding event  I couldn t even see the total items probably because the list isn t bound yet   How can I set the selected index based on a value
