Friend you can not Directly Add new item to Combo box that is Bound to Some Database items but you need to insert One Extra Row in Ds.Table[0] Which Will Contain this Select party Name before Binding ds.Table[0] to Combo Box Code like Below private void get_party_details() { cb_party_name.Items.Add( Select Party Name ); try { DataSet ds = new DataSet (); ds = gBL.show_party_details_name(); //Insert Row Here DataRow r = new DataRow (); // Here Instad of r[ 3 ] use the Index of Column Party Name according to your Database Table Structure r[3 ] = Select Party Name ; ds.Tables[0].Rows.InsertAt(r 0); //After Adding New Row Now you can bind and It Will Show Select Party Name in Combobox :) cb_party_name.DataSource = ds.Tables[0]; cb_party_name.DisplayMember = Party_Name ; } catch ( Exception ) { //MessageBox.Show(Error!:  + ex.Message.ToString() + . Please contact PSR Computers for Support); } if my answer Helps you then Check  Do you like this answer check box  :)
