Just trying a simple bind. No values are populated into the GridView however.
protected void Page_Load(object sender, EventArgs e)
{
List<string> list = new List<string>();
list.Add("Bread");
list.Add("Cheeze");
list.Add("Wine");
list.Add("Beer");
list.Add("Waffles");
GridView1.DataSource = list;
GridView1.DataBind();
}
