How to bind a ComboBox to generic dictionary via ObjectDataProvider

Question

I want to fill a ComboBox with key/value data in code behind, I have this:

XAML:

Answer 1

There's an easier way.

Convert the enumeration to a Generic.Dictionary object. For example let say you wanted a combo box with the weekday ( just convert the VB to C#)

Dim colWeekdays As New Generic.Dictionary(Of FirstDayOfWeek, String)
    For intWeekday As FirstDayOfWeek = vbSunday To vbSaturday
       colWeekdays.Add(intWeekday, WeekdayName(intWeekday))
    Next

RadComboBox_Weekdays.ItemsSource = colWeekdays

In your XAML you only need to set the following to bind to an object:

SelectedValue="{Binding Path= StartDayNumberOfWeeek}"  SelectedValuePath="Key" 
DisplayMemberPath="Value" />

The code above can easily be generalized using reflection to handle any enumerations.

hope this helps

Answer 2

The way DevExpress 17.1.7 handles this is setting those properties: DisplayMember and ValueMember, in case of a dictionary it would be something like this:

DisplayMember="Value" 
ValueMember="Key"

Answer 3

To your ComboBox add

SelectedValuePath="Key" DisplayMemberPath="Value"
