[Solved] Filtering a List<> column

[Eric Schoenholzer]

I'm binding a List<string> to a DataColumn via a ValueConverter, which returns a string:

<grid:GridViewDataColumn Header="Genres" DataMemberBinding="{Binding Genres, Converter={StaticResource ListConverter}}"  />

Now, no filter icon is shown. I tried to set a DataType, but got a runtime error.

Reading the threads here, I understand the filter works with the underlying data type. This would be a List<>.
Is this correct? Do I need to implement a comparable List<> ?
I don't see how this would help, because I would test two List<> (IComparable and IEquatable).
How would work a Contains-Filter?

What would be the easiest way? I need only the default filter for a string.

Thanks
Eric

Hi Eric Schoenholzer,

Your best option would be to create a new property on your business object that will return this string. In this way you will have just a normal string column and everything will work as expected.

I hope this helps.
