Collecting ThisItem and and a DropDown Value is causing multiple lines in my Collection

Posted on by Mike_54

Hello,

I have a drop down on a gallery. On Change of the drop down, I have the following formula: Collect(CollectionName, ThisItem, {DropDownName: DropDownName.Selected.Value}). When I look at my collection after a change, it is showing all of the attributes associated with ThisItem on one line and then a second line shows only the drop down selected value. The ThisItem attributes are feeding in from a power bi report. In the screenshot below, the 6 should be in the blank spot above. RestockQty is the column name in my formula. I wrote it generic above to be more clear.

Any help would be greatly appreciated.

Hi @Mike_54

I am assuming that you have CollectionName in the Items property of the gallery. In case you want to modify the record, you need to update the expression to:

Patch(CollectionName, ThisItem, {DropDownName: DropDownName.Selected.Value})

Collect is used to only add new values and not update the existing ones.

Hope this Helps!

Thank you for the reply! I do have a separate gallery with CollectionName in the item property. This gallery, however is showing the data coming in from power bi. Then, the user selects a value in the drop down and it should add a row for that item with the new drop down qty to the collection. So, the collection is blank before the user selects a drop down value. Is that more clear?

In case, you want to collect only the dropdown selections, can you update the expression to: Collect(CollectionName, {DropDownName: DropDownName.Selected.Value})

Hope this Helps!

Thank you.

Ideally, I would be able to add all the info attached to the item to a row in my collection with the selection in the drop down. If I change my formula to Collect(CollectionName,{Article: ThisItem.Article, RestockQty: DropDownName.Selected.Value}) then it will put them on the same row. I have to spell out all the columns I want, but not a big deal. The only issue now, is that I have multiple items and each has it's own drop down. However, if I select the first item and a drop down value of 1, I see it correctly on my collection. If I then select a second item's drop down and choose 2, it will add another row to my collection, but it will now show the selection of "2" on both rows. How can I get the collection to show the selected value in the specific drop down associated to each item?

Hi @Mike_54

I used the same expression that you are using and I am able to get the required results. Can you confirm if you have any other expression that might affect the behaviour?

You're right. There were something off on the gallery where I was showing my collection. Everything is working now. Thank you! I'll mark your answer as a solution.
