I created a GridView that shows a List<object>, this "object" could be several types, all these types inherit from a same type. This base type has 3 properties:Key, Value and Icon.
Now I show my XAML
I attached what it shows at runtime.
The ValueColumn has not the filter control.
The only things is that DataMemberBinding has connected with a Converter because Value property should be several type, but this converter return ever string.
Is it for this reason that not appear a filter control?
This is a converter code (Column of value is not editable)
