Hi,

 

This Dataverse table contains a column with attachments.

 

How to display an icon within a Gallery in a canvas app to allow the users to download the file?

 

With Sharepoint lists, we'd just use the Launch function with something like:

"ThisItem.Attachments.AbsoluteURI" on the OnSelect property.

 

But it seems the AbsoluteURI doesn't exist in Dataverse, si how to dowload Dataverse attachments from a Canvas app?

 

Thanks in advance!

    Wanna report that the method below is failed, the file cannot be downloaded ...

     

    The other method is to use attachment control instead of launch/download function in canvas app.

    Please take a look at this blog.

    Hi @WebPortal ,

     

    Please take a look at this blog-

    http://sharepoint247.com/power-apps/how-to-download-a-file-from-dataverse-file-column-in-power-apps-canvas-app/

     

    There are some escape characters in the formula.

    So please try something like this:

     

     

    Launch(glbEnvURL & "/api/data/v9.0/cr8f6_photolocationimages(" & ThisItem.PhotoLocationImage & ")/cr8f6_file/$value")

     

     

    The other method is to use attachment control instead of launch/download function in canvas app.

    Please take a look at this blog.
