Changing Each Row Color During Run-time In Listview Based On Database Entries

I want to change color of each row in a listview based on a data which is stored in database.
I've written following code but I don't know by the help of which object I can access to markup property of listview :

protected void ListView1_ItemDataBound(object sender, ListViewItemEventArgs e)
{
if(e.Item.ItemType == ListViewItemType.DataItem)
{
ListViewDataItem dataitem = (ListViewDataItem)e.Item;
int policyid = (int)DataBinder.Eval(dataitem.DataItem, "policyID");
if(policyid == 3)
//what should I write here to change the corresponding row's color?
}
}
