The purpose of databind is to bind the data so as to display
i.e
string query1 = "Select * from Links";
SqlConnection con1 = new SqlConnection(strcon);
SqlCommand cmd1 = new SqlCommand(query1, con1);
SqlDataReader sdr1;
con1.Open();
sdr1 = cmd1.ExecuteReader();
gridLink.DataSource = sdr1;
gridLink.DataBind();
con1.Close();
