带有 sort() 和 distinct() 的 PowerApp Gallery

Question

I created a Gallery with a Title == Name and a subtitle == First Name by item.

I want this gallery to be sorted and remove duplicates.

I tried this:

Sort(Distinct(Data_source, Name), Result)

The problem is that I get Title == Name and subtitle == Name instead of Fisrt Name.

How can I keep different fields?

Thanks

As you noticed, the Distinct function will only return the distinct values from the selected column, and discard the other ones. If you want to preserve the other values, you can use the GroupBy function , and take one of the elements of the group. Something along the lines of the expression below:

ForAll(
    GroupBy(
        Data_source,
        "Name",
        "ByName"),
    Patch(
        { Name: ThisRecord.Name },
        First(ThisRecord.ByName)
    )
)
