The solution works fine but I had some problems with it.
I was convinced that
PropertyName =
FieldName.
This information I found in an example given: FilterDescriptor - implements filtering property (
field)
name. <- column1.FieldName?
For this reason, when an earlier attempt to use this approach has not got any results.
It turns out that the
PropertyName =
Name of column.
I think PropertyName is a little confusing, at least for me.
