let view = CollectionViewSource.GetDefaultView(collection)

view.Filter <- new Predicate<obj>(fun (o:obj) -> true)

this throws the below exception,

>>>>>>>>>>

Error	1	Lookup on object of indeterminate type based on information prior to this program point. A type annotation may be needed prior to this program point to constrain the type of the object. This may allow the lookup to be resolved.

I'm trying to use the ICollectionView.Filter property in a WPF sample. Any ideas on how to set this delegate?

Hi,

I don't get any problem with it. I tested with a sample project. You can find the code at [link:codepaste.net]

view. Filter = new Predicate<object>(fun (o:obj) -> true)

thats the code exactly. Using the Predicate<object> delegate as a property is causing the issues. Any help is greatly appreciated. Please consider = as <- here!

Based on your code snip, I changed a small tweak, it works fine now!
