Working with FilteredBindingList

Hi guys:

I'm using a FilteredBindingList(which implements the BindingList, IBindingListView interfaces).

Making an instance of FilteredBindingList (FilteredBindingList), I'm using it as Data Source of a System.Window.Forms.BindingSource object. Using the "Filter" property of BindingSource object, I'm filtering the datasource according to the value of "Filter"

someBindingSource.Filter = string.Format("key={0}",someComboBox.SelectedValue)));

It works fine if I set this "someBindingSource" as datasource of a datagridview. But, if I remove an item from the filtered datasource of the "someBindingSource", the result is wrong, because if I code someBindingSource.RemoveFilter(), the removed item is still on the current DataSource property of "someBindingSource", but the immediatly record which I'm not remove, was removed.

Any of you know why this happens???

Thanks in advance. I' really appreciate.

Thank you Iftikar. So my real problem is not about how to implement the list and filter the DGV, is about how to remove an element from the bindingsource correctly. If I remove programatically an item from the bindingsourtce using the "Remove" method, it happens what I describe. As long as my bindingsourtce is filtered, the removed item is the right item(For example if i got A & B, and I remove B, it suppose that remains A), but if I remove the filter using "RemoveFilter()" method, the remaining item is B instead A.
