SelectedValuePath did not work properly

[Lion Pham]

Hi,

I'm using RadListPicker but I have a problem when using it. 

I have a Dictionary<String, String> named Source:

Dictionary<String, String> Source

When I set SelectedValuePath propery of RadListPicker to "Key", a run-time error occured: {System.ArgumentException: Value does not fall within the expected range.}

<telerikInput:RadListPicker
ItemsSource="{Binding Source}"
DisplayMemberPath="Value"
SelectedValuePath="Key" />

Can you help me to solve this problem?

Thanks in advanced.

Hello Dung,

This behavior is expected since the enumerator of the Dictionary class enumerates the values. In that case, you should simply bind the control without using SelectedValuePath or think of a way to encapsulate the Key-Value pairs in your own data objects.

Hope this helps.
