Is this the way you bind the datatable?

C#

cmb.DisplayMember = "Colname1";
cmb.ValueMember = "Colname2";            
cmb.DataSource = dt;

i done in this way but only single value is fetch

use just see that....
sqlSelect = "select AI_Center_Name from tbl_CenterEntry";
dt = cls.FetchDataTable(sqlSelect);
sqlSelect = "select AI_PriCenter_Name from tbl_PrivateCenterEntry";
dt1 = cls.FetchDataTable(sqlSelect);
dt.Merge(dt1);
dt3 = dt;

drpCenter.DisplayMember = "AI_PriCenter_Name";
drpCenter.ValueMember = "AI_Center_Name";
drpCenter.DataSource = dt3;

C#

dt.Merge(dt1);
           dt.Columns.Add("Center", typeof(string));
           foreach (DataRow dr in dt.Rows)
           {
               dr["Center"] = dr["gov_center_Name"].ToString();
           }
           foreach (DataRow dr in dt.Rows)
           {
               if (dr["Center"] == "")
                   dr["Center"] = dr["pri_center_Name"].ToString();
           }
           comboBox1.DataSource = dt;
           comboBox1.DisplayMember = "Center";
