<asp:ListItem Value="item1" Selected="True">Item 1</asp:ListItem>

C#
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
ddListTest.ClearSelection();
ddListTest.Items.FindByValue("item2").Selected = true;
}
}
1) Add dropdownlist to your website
and in code-behind try to select some item by using FindByValue

2) But what about if i whant to set previously selection of any item in html like this example:

To solve this issue just add ClearSelection before your assignment like this:
And the result
That's all, hope this helps somebody.
