In SPO list why would FilterFieldX/FilterValueX work while FilterName/FilterMultiValue is ignored?

Question

I am using a custom list with standard OOB AllItems.aspx view using the modern experience. (NOT a web-part, NOT the classic experience)

When I filter using

.../AllItems.aspx?FilterField1=MyTextColumn&FilterValue1=MyVal

it works fine and I see only rows containing MyVal.

When I filter using

.../AllItems.aspx?FilterName=MyTextColumn&FilterMultiValue=MyVal

or

.../AllItems.aspx?FilterName=MyTextColumn&FilterMultiValue=MyVal;YourVal

The list view acts as if no filtering was applied - all rows are displayed.

Ultimately the column I want to select on is "Single Line of Text" but I have gotten the same results using "Choice" and "Person or Group" and "Yes/No" as well. They work fine with FilterField1/FilterValue and they ignore FilterName/FilterMultiValue.

• Is there some special configuration I have to do for SPO to allow for filtering by multi-values?
• Is this a feature that works only with list web-parts and not with standard list views?
• Is this a feature that is no longer supported? (Most of the references I've read are from 2010-2014)...
• Am I mistaken in my understanding of how this should work? Should I be able to directly replace FilterField1/FilterValue1 with FilterName/FilterMultiValue and have it work identically?

I have checked about 20 times to make sure I have correct case and spelling on FilterName/FilterMultiValue and I have even tried (as I've seen on a couple sites) FilterField1/FilterMultiValue1 and various other permutations.

Perhaps unrelated but FilterOpX is being ignored as well. I saw several comments that this was a difficult-to-reproduce problem that occurred on some sites/lists and not on others...

Answer 1

You need to use the Filter in below format:

.../AllItems.aspx?FilterFields1=MyTextColumn-FilterValues1=MyVal;#YourVal

Note ;# as a separator between two values.

Answer 2

So apparently the

useFiltersInViewXml=1

query parameter is a thing. Maybe just in SPO or maybe just in Modern Experience. I'm finding ZIP in terms of documentation from M$, but when I add that into my query:

.../AllItems.aspx?FilterName=MyTextColumn&FilterMultiValue=MyVal;YourVal&useFiltersInViewXml=1

then all of a sudden the world is my oyster...

Hope this helps someone else. If someone sees someplace where this is decently documented please comment below.

---EDIT---

My oyster ended up without a pearl. It works beautifully at first but some random number of seconds after that SPO does a reload via AJAX which ignores the filters I have specified.

TRY AGAIN:

This time I went into the unfiltered view, filtered by the columns I'm interested in, and reverse engineered the resulting URL. I end up with a query that looks like this:

.../AllItems.aspx?FilterFields1=MyTextColumn&FilterValues1=MyVal%3B%23YourVal&FilterTypes1=Text

Note that I have changed the URL as follows:

• FilterFields1 instead of FilterName
• FilterValues1 instead of FilterMultiValue
• separating my multi-values with %3B%23 (which is ;# encoded)
• added the FilterTypes1=Text query parameter for this "Single Line of Text" column type
• no longer using useFiltersInViewXml=1

Some "Gotchas" to be aware of:

• If your dynamic query sometimes allows multi-values and other times has only a single value you must change your URL (FilterField1 and FilterValue1 without the s)
• FilterTypes1=Text will change based on column type - manually filter and examine the resulting URL to figure out what you need
• While FilterName/FilterMultiValue supported (or was supposed to support) * as a wildcard, this is not supported here with this syntax
• I'm testing this only on Sharepoint Online as of Aug-2019 - YMMV elsewhere
