After the
DataBind()
you can do one of the following:
ddlstudentname.Items.Add("Foo"); ddlstudentname.Items.Add(new ListItem("Foo")); ddlstudentname.Items.Add(new ListItem("Foo","Bar"));
ddlstudentname.Items.Insert(0, "Foo"); ddlstudentname.Items.Insert(0, new ListItem("Foo")); ddlstudentname.Items.Insert(0, new ListItem("Foo","Bar"));
