What do you mean load an item? You want to add another item?

hi dear,

I don't understand. what you want ? I give some information. Please observe it.

private void FxComboBox()
        {
            SqlConnection objConn1 = new SqlConnection("Data Source= Sql Server Name ;Initial Catalog= Database Name ;user id=sa; password=123;"); // Write you sql server database name and necessary option.       
            string SQL = "Select * From TableName";
            SqlCommand cmd = new SqlCommand(SQL, objConn1);            
            SqlDataAdapter da = new SqlDataAdapter(cmd);
            DataTable dt = new DataTable();
            da.Fill(dt);
            if (dt.Rows.Count > 0)
            {
                comboBox1.DataSource = dt;
                comboBox1.DisplayMember = "ColoumName" ;
                comboBox1.ValueMember = "ColoumName" ;
                comboBox1.DropDownStyle = ComboBoxStyle.DropDownList;
            }
        }
