根据WPF中GridView / ListView的相邻单元格的值进行过滤

Question

I have a ListView with a variable number of items in a WPF project with two columns. Column A is a string, column B is a combobox. I have the ListView bound to some collectionView, and the combobox column is a cellTemplate, binding the combobox to some other collectionView or observableCollection.

Is there some way to filter the collection shown in the combobox in column B dynamically based on the value of column A?

I am open to replacing the ListView with some other control if it would grant me the functionality described.

Answer 1

Perhaps you could achieve this by binding the combobox property B's ItemsSource to

{Binding Path=PropertyA, Converter={StaticResource ItemsConverter}} 

Then write a IValueConverter which takes a TypeA and returns a IEnumerable. Whack that into the Resources so the StaticResource can find it.

Bob's your uncle.
