I have a Combobox that I am using to filter a GalleryGrid tied to a Sharepoint list. I am using a table formula in DefaultSelectedValues that pre-populates the values, but I have tried manually selecting the options. In both cases, no matter what order I put these values in, it only filters on the last value. Visually, I can see multiple options are selected, but it only filters the gallery on one of the values.
The Combobox obviously has multiple choices enabled… see attached screenshot
I don't see a screenshot but if you put Set(var, Self.SelectedItems) in the OnSelect property of the combobox and then make the Items property of the Filter(SPlist, columnname in var) it should work. In the screenshot, the gallery of sales orders is filtered by Country selected in the combobox. FYI, There will be a delegation warning when the "in" operator is used when filtering a SharePoint list.
When I change Items to Filter('Task Assignments','Leave Type' in var) it throws an error message on my “clear collect” button that refreshes the SP list and it doesn’t filter on the column at all. And I can’t select any options anymore...
