Multiple to Multiple table problem

(0) ShareShare

Posted on by 33

Hi,

I have an app that creates events for a company but allows some of the drop-downs to have multiple selections. When I save the page and patch the items, the multi-select dropdowns don't populate the page when I return to it to make edits.

 

I understand that there is an "invisible" table holding the selections, and I see then in the formula bar, but cannot get them to populate.

    @bigwookie3000 - what is in the Default Selected Items property in your Combo Box?

    Default Selected Items = EventGallery.Selected.FoodItems

    @bigwookie3000,

     

    If the ComboBox is tied to a Form, I would have expected the following on the DefaultSelecteditems property:

     

     

     

    Parent.Default

     

     

     

    If the ComboBox is not part of a Form, then one method is to apply a LookUp function to get the relevant record, and then return the multi choice column associated to that record (again, on the DefaultSelectedItems property):

     

     

     

    LookUp(
     YOUR_DATA,
     YOUR_ID_COLUMN = varRecorditem.YOUR_ID_COLUMN,
     varRecorditem.YOUR_MULTICHOICE_COLUMN
    )

     

    Replace varRecord with the variable name you’re using to identify the selected record.
