IEnumerable> in DisplayMemberPath

Question

How do you show this in DisplayMemberPath so let's say I have the property

public IEnumerable<KeyValuePair<string, string>> Defaults{ get { return defaults; } }

in the class QuestionsFile and I want to put this in the following ListBox

<ListBox ItemsSource="QuestionsFile.Defaults" DisplayMemberPath="?"/>

What exactly do you want to display? The key and the value? Why aren't you just using a POCO with two properties which are named appropriately for the object your KeyValuePair represents? — BenCr, Mar 31 '11 at 11:42
It's just the value which I want to show.. but I'll will do It like that — Stef Dhollander, Mar 31 '11 at 11:48

You should set the DisplayMemberPath to Key or Value :

<ListBox x:Name="lst" DisplayMemberPath="Value"/>

and assign ItemSource in code behind :

lst.ItemsSource = Defaults;

or in xaml :

<ListBox ItemsSource="{Binding Defaults, RelativeSource={RelativeSource FindAncestor, AncestorType=Window}}" x:Name="lst" DisplayMemberPath="Value"/>

You're proposing using a string for an ItemsSource: did you mean to put a binding here, mathieu? – Kieren Johnstone Mar 31 '11 at 12:01
But isn't this the same as what I did? I just did it in xaml? – Stef Dhollander Mar 31 '11 at 12:10
found it: I did it like mathieu said, but I set the Defaults asEnumerable – Stef Dhollander Mar 31 '11 at 12:17

<ListBox ItemsSource="QuestionsFile.Defaults" DisplayMemberPath="?"/>

Do you mean this?

<ListBox ItemsSource="{Binding Path=Defaults,ElementName=thisCtl}" DisplayMemberPath="?"/>

(Assuming thisCtl is the x:Name property value for the QuestionFile control)

the '?' was just for filling in what has to be there ;) – Stef Dhollander Mar 31 '11 at 12:07
