Hello to all,
I'm pretty new to Castle AR and I'm doing my first Winform application
with AR.
I have a problem with combobox databinding and I'm sure a lot of
people do what I will do.
My problem:
I have class PersonType and Person:
public class PersonType: AcriveRecordBase<A>
{
private Int32 id;
private String description;
...
}
public class Person: ActiveRecordBase<B>
{
private Int32 id;
private String description;
private PersonType personType;
...
[BelongTo]
public PersonType PersonType
{
get { return personType; }
set { personType = value; }
}
...
}
This works all fine. My problem is now on coding the Winform to edit a
Person. I have a bindingsource (bindingsourcePerson) with one instance
from Class Person data bound and 2 controls bound to property Id and
Description. This works fine.
Now I have added a combobox. I fill it with another bindingsource
(bindingsourcePersonTye) that has as datasource = PersonType.FindAll
(). This populates the combobox. As Displaymember I have put the
Description property. The valuemember is empty; because I want that
the combobox returns the selected object itself. The SelectedValue is
bound to the property PersonType from the bindigsoucePerson.
No when I open the window, the combobox don't display the correct
PersonType from the Person I’m editing (all other controls are fine),
but if I select another item from in the combox (combobox is filled
correctly), it updates class Person and saves changes on the database
correctly.
The only problem I have is when I open the form or change the current
object bound to the bindigsourcePerson. It doesn’t refresh/select the
correct item from the combobox.
Any suggestions?
Has someone a Winform example with a combox where the selectedvalues
is binded to a object property?
Thanks,
Alex B.
