DataGridView Filter a BindingSource with a List of object as DataSource

Question

I'm trying to filter a BindingSource with a BindingList as Datasource. I tried BindingSource.Filter = 'Text Condition' But it didn't work, nothing happens, the data on screen remains the same. But if i use a DataSet as the datasource it works. Is It possible to filter a list of objects with the BindingSource.Filter property? I have the following class: ``` class Person { public String Nombre { get; set; } public String Apellido { get; set; } public int DNI { get; set; } public int Edad { get; set; } public Decimal Tamano { get; set; } } ``` This is how i use it: ``` BindingList personas = new BindingList { new Person{ Apellido = "App1", DNI = 3011, Edad = 20, Nombre ="Name1", Tamano = new decimal(1.7)} ,new Person{ Apellido = "App2", DNI = 1520, Edad = 30, Nombre ="Name2", Tamano = new decimal(1.5)} ,new Person{ Apellido = "App3", DNI = 5654, Edad = 21, Nombre ="Name3", Tamano = new decimal(1.6)} ,new Person{ Apellido = "App4", DNI = 778, Edad = 40, Nombre ="Name4", Ta…

As per http://msdn.microsoft.com/en-us/library/system.windows.forms.bindingsource.filter.aspx

Only underlying lists that implement the `IBindingListView` interface support filtering.

`BindingList<T>` does not appear to implement `IBindingListView` - and since it is the underlying list, your collection will not filter.

BindingSource class, while not generic, does implement this Interface, so try using this as your personas collection. I get the feeling that simply assigning a new BindingSource's datasource to a BindingList won't suffice, since it doesn't change the underlying list. Try:

```
BindingSource personas = new BindingSource { new Person{ ... }, ... };
```
