Hello
I am a really- really beginner regarding nHibernate. I have a problem, and I tried the last three days to solve it, without any result.

I have a test database with two tables: Employees:EmployeeID,EmployeeName,EmployeeAge
Children:ChildName,EmployeeID, ChildName

Now, when I load the data from Child table, instead of telling me the EmployeeID , it says n a datagridView: WindowsApplication1.Calsses.Em,ployee.

This is because, I Think, I created the structure like that in ChildrenClass:

private Employee employee;

public Employee EmployeeID
{
get { return employee; }
set { employee = value; }
}


the .hbm.xml file:
<many-to-one name="EmployeeID" class="WindowsApplication1.Classes.Employee,WindowsApplication1" column="EmployeeID"/>


and I loaded the information like this:
IList lstChildren =(IList) session.CreateCriteria(typeof(WindowsApplication1.Classes.Children)).List();
grdChildren.DataSource = lstChildren;



Please tell me what is wrong here??

You need to override your ToString() method in your Employee object. Since 'EmployeeID' is actually and Employee object, the DataGrid is just firing the ToString() method on each object...which defaults to the Type name when it isn't overriden.

Hope this helps.

How are you setting the datasource for your datagrid?

I use the IList returned from the Session like this.

session.CreateCriteria(GetType(Employee)).List
dataGridView1.datasource = list

Then you can either let the datagrid build the columns for you using reflection or you can specify which properties you wish to display.

Hope this helps
