Custom Filter Provider

Hello,

I'm testing the use of a customer filter provider that I want to use to filter two properties.

I've created a filterProvider based delegate CustomFilter and a FilterValue class that contains the properties to filter the BO list with. But I can't seem to apply the filter, because I can't (and don't) want to specify a propertyname.

My declaration:

FilteredBindingList<BO> list = new FilteredBindingList<BO>(boListInstance, CustomerFilter);

list.ApplyFilter(null, new FilterValue("A", "B"));

In the VB examples in the forum Rocky used Nothing to prevent using a specific property (at least I think that's what he meant to do?!), but VS bugs out on an ambiguous call error for the overloaded method ApplyFilter.

Any thoughts?

Regards,

Yes, I was wrong in using Nothing/null - free-hand coding is troublesome - I want the forum software to include C# and VB compilers

It should be

list.ApplyFilter("", new FilterValue("A", "B"));

Using an empty string will get the desired result without the ambiguous method issue.

Hmmm...I could have thought of that... Thanks! I can go to sleep now :)
