About the Power Apps Index function

When using the Index feature in Power Apps, is there a way to get the 2nd to 4th Index when there are a total of 5 Indexes?

I can use 'Index(Choices(Table1.ID), 1).Value' when getting a single value, but what about data in a specific range?

Regarding the errors in their formula: Range and IndexOf are not Power Apps functions - please ignore any AI prompt responses provided to you now and in future, most of the AI models are not good at Power Apps or Power Automate.

 

To answer your question

To get rows from a table that have an ID of between 2 to 4 you can use:

Filter(Table1, ID >=2 && ID <=4)

However, this formula is not delegable, so always ensure whatever data you are pointing your at is already trimmed to under 2000 records.

@kjk4563 with regards to your example try this:

 

LastN(
    FirstN(
           Choices(
               Table1.ID
            ),
            4
    ),
    3
)

 

 

You can also make it dynamic. But keep in mind that FirstN and LastN are not delegable functions.

 

Here is an example of how to make it dynamic. 

BF35CC50-74BD-4696-947C-38C8126903F6.GIF

 

For items property of the combobox I used:

 

LastN(
    FirstN(
        [
            "Item 1",
            "Item 2",
            "Item 3",
            "Item 4",
            "Item 5",
            "Item 6",
            "Item 7",
            "Item 8",
            "Item 9",
            "Item 10"
        ],
        txtIndexTo.Value
    ),
    txtIndexTo.Value -txtIndexFrom.Value+1
)

 

@BhargavPatel 

LastN(
    FirstN(
           Choices(
               Table1.ID
            ),
            4
    ),
    3
)

 

The above code throws an error.
'Text value is required.'

This is a Prompt Response.

 

Yes, you can use the `Filter` function along with the `Range` function to achieve this in Power Apps. Here's how you can get the values of the 2nd to 4th indexes when there are a total of 5 indexes:

 

Filter(Choices(Table1.ID), Range(1, 3).Contains(IndexOf(Choices(Table1.ID), Value)) ).Value

 

Let me explain this:

1. `IndexOf(Choices(Table1.ID), Value)` returns the index of the specified value within the choices.
2. `Range(1, 3)` creates a range from 1 to 3, representing the indexes from the 2nd to 4th.
3. `Filter` function is used to filter the choices based on the condition specified in the `Range`.

This will give you the values corresponding to the 2nd, 3rd, and 4th indexes from the choices in `Table1.ID`.

There is an error in your code.
Contains are not available.
Please correct it.

@kjk4563 You need to use either a gallery control, a combobox, a dropdown control... a control that displays an Array or a Table, because you are bringing in more than one value. 
On the other hand, if you want to combine all the values in one field and use a Text Input or Label you will have to merge all the values first. That will look something like this:

Concat(
LastN(
    FirstN(
           Choices(
               Table1.ID
            ),
            4
    ),
    3
),ID,   // If ID doesn't work change this to Value
    "," // You can replace "," with any other separator
)
