Cascading Drop Downs Not Populating in SharePoint List

(0) Share

Report

Posted on by theBrianL

I created four fields using single line of text in a SharePoint List.

I then used Integrate/Power Apps/Customize Forms on the SharePoint List. I then created Cascading dropdowns from a data source list in SharePoint. After publishing to SharePoint, I click on the Plus + for new item. The cascading drop downs are working correctly, but when I save the new item, nothing populates in the fields that had the cascading drop downs. It's all blank. Any idea how to fix, so data populates into the SP list?

Check the Update property of the DataCard for each field to make sure it is the saving the correct value. Also make sure the DataField property for each of those DataCards has the correct field name in it.

For example the DataCard for the dropdown may have the Update property as dropdown1.Selected.Value and the DataField as "SharePointTextFieldName"

This is the formula for one of the dropdowns: Distinct(Filter(QryStoreLookUP, Company_x0020_Name = DataCardValue7.Selected.Result),SalesPerson)
I don't see an Update value. Where would that be located?

Update isn't a property of the dropdown control. It is the property of the DataCard the dropdown is in. The DataCard determines what is being saved when the form is submitted. When you created the custom form from SharePoint all this was created for you based on the fields in SharePoint. However, it sounds like you changed one of the text fields to a dropdown on the Power App form which means you will need to change the Update property of the DataCard, so it knows to grab the value in the dropdown.

Is this the right place? If so how do I modify this? Thanks for your patience.

That is an Update property. You may need to unlock the card to modify the property. You can do that by selecting the DataCard and going to the property pane on the right and selecting Advanced then you should see the option to unlock the Card. But first make sure that is the DataCard for the SharePoint text field that you want to update with the dropdown control you created.

Hi Jeff, Thanks for your help. I updated the formula in the Update field to DataCardValue10.Selected.Result. As Result was the only hint as to what to put. This is the only place I see an Update section. The red error X that I was getting went away, but it still doesn't populate anything when I go to SharePoint site and add a new record. Do you know the formula that I need to change this too to make the values populate in the SharePoint List?

It didn't publish the most recent version. After I published, it started populating! Thanks!
