Display member and value member SeachLookupEdit Combo

Question

Hi All,

 

I have a  SeachLookupEdit Combo which I use to fetch data from my Datasource as follows.

 

public partial class frmGatePass : DevExpress.XtraEditors.XtraForm{ 

 

private ISupplierService _supplierService;

private readonly Supplier _supplier;

 

private void frmGatePass_Load(object sender, EventArgs e){

supplierBindingSource.DataSource = _supplierService.GetAll();

}

  

private void contactNameSearchLookUpEdit_EditValueChanged(object sender, EventArgs e) {

try {

var selectedSupplier = contactNameSearchLookUpEditView.GetFocusedRow() as Supplier;

if (selectedSupplier == null)return;

 

_supplier = _supplierService.GetById(selectedSupplier.ContactId);

_supplier.ContactId = selectedSupplier.ContactId;

 

selectedSupplierContactRelationId = selectedSupplier.ContactRelationId;

telephoneTextEditScreen.Text = selectedSupplier.Contact.Telephone;

} catch (Exception Errhandler) {

MessageBox.Show(Errhandler.Message);

}

} 

} 

 

And My Data Binding is as follows:-

DataSource = supplierBindingSource,

Display Member = Contact.ContactName,

Value Member = ContactId.

 

My Problem once I click an item on the drop down list, first it picks the right item, but if I felt I made a wrong choice and click to select another item, I get the Primary Key Id within the List in the first row. How do I sort This kind of an issue.

 

Thanks
