How to show the data from mssql statement at ComboBox list after binding with datasource.

i write sql statement as

select customer.Company_Name from customer where customer.Company_Name like '%' + @status + '%'

and code is like that

private void cboCustomer_KeyPress(object sender, KeyPressEventArgs e)
{
 //cboCustomer.Items.Clear();
 cboCustomer.DataBindings.Clear();
 string str = cboCustomer.Text;
 DataSet data = logic.GetData_By_Desc("SearchbyCustomerName", str);
 DataTable table = data.Tables[0];
 if (table.Rows.Count > 0)
 {
   for (int i = 0; i < table.Rows.Count; i++)
   {                           
      //cboCustomer.Items.Clear();
      //cboCustomer.DataBindings.Clear();
      cboCustomer.Items.Add(table.Rows[i]["Company_Name"].ToString());
    }
  }
}

while using that, the error display as "Items collection cannot be modified when the DataSource property is set."

how should I change the program?

Thanks!!
