re: Looking for a good way of sorting a ListView

If you change the signature of your sort method to:

public void Sort(ISortableGridViewColumn column)

Caliburn should be able to perform the interface cast and you shouldn't need a dependency on the control from within your presenter.

You might even think about renaming the interface to be less control focused. Perhaps something like ISupportSorting or ISpecifySorting, etc

I have no experience with BindingListCollectionView but the same problem is discussed here:

And it looks like the answer is unfortunately no.

If I do like:

var tmp = CollectionViewSource.GetDefaultView(_listBox.ItemsSource);

tmp has type BindingListCollectionView. Trying to cast this to ListCollectionView throws a exception.

I cant find any way to use custom sort on a BindingListCollectionView,, is there?

Hi Lasse,

check in debug what type is returned by CollectionViewSource.GetDefaultView when bound property in not an ObservableCollection.

Maybe the method you have problems with should return simply ICollectionView. I will check that later.

Hi.

I am trying to copy your solution but having problems with GetListCollectionView() which throws an exception "unable to cast ..."

Difference between your example and mine is mainly that I use BindingList<T> instead of ObsevableCollection<T> and I try dont have CreatureCollection as property like you. My ListBox is in a control templade where its ItemSource is using databinding to its parents Itemsource.

Any ideas how to get the casting correct.

Monica,

Thank you for the code.

Your example does what I want, except, I need to do it all in code. (My WPF window has a varying number of TextBoxes depending on several factors.) So far, I've been baffled by how to set the bindings, paths, updateTriggerSources in code.

I'd appreciate your naming a place I could look for this or might you re-write the XAML into C#?

Thanks

Very cool, although I agree that the implementation is naive.

Also, you'd never ever want to hardcode rules validation like this.

You should try using one of validation frameworks, like Castle Validator component. (NHibernate Validator could be used as well, I supposed, although I'm nor sure it's suitable for UI validation)
