Update Existing Collection Prior to Writing to Sharepoint

[Amghost]

Scenario:

I have a three part form/process on a single page.

Top of Form:

>User Inputs a number of text fields.

>User Clicks "Add to worksheet" which adds to the gallery below and clears the fields so they can add additional items.

Middle of Form:

>Simple galleries (2) that show the data they entered above.

Bottom of Form:

>User must complete an explanation (Rich Text).

I then have a Button that uses:

ForAll(Collection, Patch(SharepointList, Defaults(SharepointList), { xxx:xxx, xxx:xxx}))

***However, I want to also add the explanation to the sharepoint list when the button is hit, but it is not in the collection.  After all the data (Gallery and collection) is posted to the list, I want to clear everything and navigate to a page that displays the data from the list for Approval Routing.

I am trying:

xxxxx})); Collect(Collectxxx, Patch(xxxxx, Defaults(xxxxx), {Explanation: Explanation}),Clear(CollectAdjustDetail))

That is not working.  Need ideas....

Hi @Amghost ,

Could you please share a bit more about your scenario?

Do you want to update the explanation text into your collection before patching data into your SP list?

Further, is there a "Explanation" column existed in your collection already? How do you collect data into this collection in your app?

I assume that there is a "Explanation" column existed in your collection already, if you want to update the explanation text into your collection before patching data into your SP list, please take a try with the following workaround:

Set the OnSelect property of the "Submit" button to following:

UpdateIf(Collection, true, {Explanation: RichTextEditor1.HtmlText});  /* <-- Add formula here. Update the "Explanation" column in your collection with the Rich Text value */
ForAll(
        Collection, 
        Patch(SharepointList, Defaults(SharepointList), { xxx:xxx, xxx:xxx})
);
....

Note: Please make sure you have defined a "Explanation" column in your collection to store the Rich text value.

More details about the UpdateIf function, please check the following article:

UpdateIf function

There is not an explanation in the collection as that is not added until after the initial data is in the collection.  The explanation is added after the user confirms that data entered initially at the top of the form.  I do have an explanation column in the SP list.

Hi @Amghost ,

Do you want to add a new 'Explanation' column into your collection along with proper Rich Text value before patching data into your SP List?

Why not patch explanation data to your SP List directly?

If you want to add a new 'Explanation' column into your collection along with proper Rich Text value before patching data into your SP List, I afraid that there is no way to achieve your needs in PowerApps currently.

Note: The AddColumns function would return a temporary table, rather than modify the underlying table (on your side, it is the collection)

As an alternative solution, you could consider patch the explanation data to your SP List directly. Please consider modify your formula as below:

ForAll(
        Collection, 
        Patch(
                 SharepointList, 
                 Defaults(SharepointList), 
                 { 
                     xxx:xxx, 
                     xxx:xxx,
                     Explanation: RichTextEditor1.HtmlText             /* <-- Assign Explanation value to the Explanation column dirctly */
                 }
        )
);
.... 

Best regards,
