I’ve been wondering for a while now how to filter a column according to a value. For example how would I filter a column of integers to display only values that are above / below the desired threshold?
This is a known issue. This KB article is pretty old and we cannot find the corresponding .xaml file in our sources. We are working on updating the KB article.
However, there is a dedicated activity you can use, Filter Table. For information about it, please refer to this Activities Guide topic.
Additionally, the link Vikas gave you also includes a .xaml example.
