Question

Hi I have windows form with a Combo filled with 3 options where their values are Guid’s and that has a DataBinding to a selected object.

EmployerMemberDefault item = EmployerMemberDefault();
item.GroupUid = Guid.Empty;

cbGroupEmployer.DataBindings.Clear();
cbGroupEmployer.DataBindings.Add("Value", item, "GroupUid");

When I create a new object the property that is databinded to the combo is set to Guid.Empty. If I compile and run, when I create that new object I see “00000000-0000-0000-0000-000000000000” in the combo. Is there any way I can see empty text in the combo instead of the Guid.Empty value?

Thanks.

Answer 1

Change the source property from Guid to Guid?/Nullable<Guid> I haven’t done this with Guid, but it works with int/DateTime and other types that do not allow null.
