Hi All

I have a form that contains textboxes, dropdowns and cascading dropdowns. I have managed to use the Patch function to transfer the textbox contents to my sharepoint list columns but I am struggling with the dropdowns.

The sharepoint list is called TTSiteInfo, the Patch function (on a "Submit" button) so far is below:

Can anyone add to this so the selected dropdown & cascading dropdown values also transfer?

Thanks in advance

Lee

Finally, got there. In the Size SP list I had renamed the first column "Size" however, Powerapps was identifying this column as "Title". The working formula is Size:ddSize.Selected.Title
Probably a basic beginners error.
Thank you very much for your help (and patience).

I'm getting closer, thanks. The ddProduct is working but the ddSize for some reason is not. Leave it with me and I'll try and work it out (I may be back).
Thanks for all your help so far.

@lascough20

Very good, then based on your Items property, you should have those columns in your patch formula (not seeing them now)

They would be something like this (adjust column names as needed):

Product: ddproduct.Selected.Result, Size: ddSize.Selected.<columnYouWantHere>

Your ddproduct will only have a Result column because you used Distinct - and that creates a table with a single column record of Result.

Your ddSize will have the full record from the Size list. So, depending on what column contains the text that you want to store, just change that in the <columnYouWantHere> part. So if it is something like "Title", then it would be ddSize.Selected.Title

They are single line of text columns.

Yes, I re-read through things and am not seeing what kind of columns you have for Product and Size. Are they Choice, Lookup or just Text columns?

Re: Patch Dropdown Selection to Sharepoint List Column

@RandyHayes
Sorry, I guess I'm confusing things with the different dropdowns. Ignore the Pass / ddresult as this is working.

Below are the two dropdowns I am having trouble with.

parent dd (ddproduct), - Distinct(Product,Title)
child dd (ddSize) - Filter(Size,Product.Value=ddproduct.Selected.Result)

I want the results of each to transfer to a Sharepoint list column. Basically I carry out tests on products, all of which have different sizes available. This is recorded using the Powerapp then transferred, along with other information, to a Sharepoint list (by pressing a 'submit' button). Everything is transferring apart from the results of these two dropdowns.

I hope this explains better. Thanks

Is Pass the choice column??

For the ddproduct, the only column that will be available to use is the Result column since you used Distinct on that.

For the Size, your will have all of the columns of the Size list available to you to choose from.

But I'm a little lost on what exactly is not working. You provided what "does" work. Can you provide an example of what "doesn't" work?

Re: Patch Dropdown Selection to Sharepoint List Column

The working formula is highlighted below. This is a choices column (titled 'Pass') from the TTSiteInfo list.
I tried both options you gave for the other dd's with no joy.

The items for the ddlists which will not transfer are:
parent dd (ddproduct), - Distinct(Product,Title)
child dd (Size) - Filter(Size,Product.Value=ddproduct.Selected.Result)

Hope this helps.

Yes, but can you provide:

1) your current formula that is not working

2) the Items property of your dropdown controls.

Re: Patch Dropdown Selection to Sharepoint List Column

Ok, the choice column worked perfectly but the others didn't.

There are 3 other dropdowns, two of them cascading and depend on the dd1 selection. All three are populated from different sharepoint lists. I hope this makes sense.
