DropDownLists?

This the button click event I use to retrieve data from a single dropdownlist selection:








Sub Button1_Click(sender As Object, e As EventArgs)


DataGrid1.DataSource = _


GetOrderDetails(DropDownList1.Items(DropDownList1.SelectedIndex).Text)


DataGrid1.DataBind()


End Sub





My question is how do I retrieve data from the results of two or more dropdownlists?





ie: ddl1, ddl2, ddl3.





Thanks ...
