SIlverlight 4, FilterDescriptor and GUID as FilterOperator

Question

Hey guys, as seen in this post, GUIDs are not supported by the FilterDescriptorts FilterOperator. Has anyone encountered this problem? Is there a workaround? Because, well it pretty much sucks (no filtering by foreign keys and so on... which is quite common).

Answer 1

Set the filter descriptor in code

public ClassName()
{
    InitializeComponent();
    this.DataSource.FilterDescriptors[0].Value = Guid.Empty;
}
