ISelectionAdapter

I am trying to mimic the DataGridSelectionAdapter from the Sivlerlight toolkit samples (Autocomplete box) 开发者_运维技巧but ISelectionAdapter is not found. I have refs to System.Windows.Controls and the System.Windows.Controls.Toolkit (C:\Program Files\Microsoft SDKs\Silverlight\v3.0\Toolkit\Nov09\Bin\System.Windows.Controls.Toolkit.dll).

Anyone know which assembly this is in> MS says it is in S.W.Controls, yet it appears not ( reflector cant seem to locate that interface there either).

Thanks

From MSDN docs for ISelectionAdapter:-

Namespace: System.Windows.Controls
Assembly: System.Windows.Controls.Input (in System.Windows.Controls.Input.dll)

Its not a toolkit provided interface, but you need to add the above SDK provided dll reference to get it.
