How to make data source (data item) of form datacard change on selection of a gallery option?

Posted on by Microsoft Employee

Hello! 

 

I am creating an app and ran into a problem. The app I created has too many screens and is starting to run slow...really slow. 

So, I had the idea to condense the number of screens that I have, but I do not know how to do that, and still get the effects that I am wanting. I will describe what I need to do, or what I hope can be done in Power Apps. 

 

EX.) I have a gallery, with options that can be selected and take you to individual screens that have their own forms. 

VerticalGallery:[Apple, Melons , Orange], onselect they navigate to the appropriate screens.>> [Apple navigates to appleform] 

On these forms there is a a dropdown list that has the different types of these fruits listed: [Apple: Red delicious, GrannySmith, Green]. So my question is... (using an excel online file table to provide dropdown options, and form submissions go to a sharepoint list. 

 

Can I create one form(screen) but when Apple, or melon, or orange is selected, the drop down option changes to support that specific option? 

 

Thank You for any help provided!

    You cannot use variables or collections as the datasource for a single form.  It must be an actual list or table in SQL, Dataverse, or SharePoint.  I don't see how you can change the datasource of a form programmatically.
