Individual DataGrid Row Visibility

I have a WPF DataGrid bound to a collection of Entity Framework objects that's inside a parent EF object. Something along the lines of:

<DataGrid ItemsSource="{Binding SelectedCustomer.Orders}" />

Now when I want to "delete" an Order, I don't want to actually delete it from the data source, I simply want to set its IsDeleted property to true so the data is retained.

My question is: how can I get my DataGrid to skip a row if it's IsDeleted property is true? I would really like to use binding and not codebehind. Something like this would be wonderful:

<DataGrid ItemsSource="{Binding SelectedCustomer.Orders}" RowVisibilityPath="IsDeleted" />

Kind of along the lines of DisplayMemberPath. I realize I would need to convert the state of IsDeleted, but that's a different topic.

Any ideas?
