Binding to an enumerated column

Question

I’m on a Windows application using SQLExpress with EF.5  CodeFirst  in VB

I create an enumerated property. So far everything went well.

Now I’m trying to create a simple binding over that column to a dropdown list.

From the binding source to the control, everything is fine but binding source is not updated when I change dropdown list selection.

Tried a few advices found over the blog but nothing worked

Tired to bind “text” or “selectedindex” property result is the same, I think binding source is expecting an enum element not a number or a text, but don’t know how to do this

Can somebody help me ?

Public Enum EnumNumbers As Short
    zero= 0
    one= 1
    two= 2
End Enum

'...
' ------- in the data class 
Public Property EnumNbr As EnumNumbers = EnumNumbers.zero 

' ------- in the form
MyCombobox.DataSource = system.Enum.GetNames(GetType(EnumNumbers ))

MyCombobox.DataBindings.Add("text", MyDatasource, "EnumNbr")
' or
MyCombobox.DataBindings.Add("selectedIndex", MyDatasource, "EnumNbr")

Convert it to VB it can't be that hard. http://stackoverflow.com/questions/906899/binding-an-enum-to-a-winforms-combo-box-and-then-setting-it

Answer 2

Thank you for your reply, but this thread relates only to the part that is already working for me. (Loading and controlling a combo box from an enum) my problem is with the “return path” of the binding. (What happens to the bindingSource when my combo’s selected item changes)

Regards.

Then I suggest that you post to a Windows UI form forum like MSDN VB.NET General and ask questions about the bindings.
