Posted on by tpii

Hi, I have a Sharepoint site with a list, library, and a collection the collection was created from the files in the library.

Mylist (three column names: Name, Number, FileName) , Mylibrary (a group of PDF files named, FileName.pdf (matches the File name field in the list and collection) , Mycollection

I created a screen with a searchable gallery (either the Name or Number column) in MyList. works well.

I want to place an icon on the right side of the gallery box that will launch the PDF file with the same name as my list from either MyLibrary or MyCollection.

Hi @tpii ,

You did not say how exactly MyCollection was collected, so I will give you two possibilities.
If the collection contains the metadata for the library, then one of Launch(‘link to item’) or Launch(‘link’) should work (sorry I am not in front of my PC). You will see the parameters come up when you type Launch.
Otherwise you can launch it with the absolute URL (I assume it is in SharePoint). Launch(<SharePoint folder URL> & (file name)

Warren, thanks for the note. I did find a solution in my code based on your note. I was not enclosing the hyperlink to launch in double quotes. frustrating to know what the app wants where, quotes, brackets, curvy brackets, square brackets... It almost seems each command has its own quirks.

thanks again, Tom

Hi Tom @tpii ,
Yes - Launch URL are strings, and any text outside control references needs to be in quotes.

Can you please accept as a solution to close this and also allow others with similar queries to easily find it.

'Link to item' gives a weblink that is a mixed bag for Launch function.
Example: SharePoint URL/Nameofdoc.docx?d=w"GUID"&csf=1&web=1&e=etc...

The way around this is to create a direct link from the value returned by 'Link to item"

Launch(Left('DataCardURLvalue',Find("?d=",'DataCardURLvalue')-1))

PowerApps will Launch( based on the extension the string ends with ".docx" or ".PDF" example.
(Left return the address value Left of the Find( "?d=" This will be the absolute URL mentioned by @WarrenBelz
Data source
Find("?d=" this is the first part of the unwanted web string right of our extension ".docx" or ".PDF"
Data source
-1) Remove the question mark from the end of direct link .docx?

Launch(Left('DataCardURLvalue',Find("?d=",'DataCardURLvalue')-1))

If you are using 'Link to item' in a gallery or in a Form data card. Its not going to give you a direct link. If you view it as a URL it will open in Web View. Library settings for Default application do not apply to web view links. So you need a direct link if you want to launch the document.

Launch(Left('DataCardURLvalue',Find("?d=",'DataCardURLvalue')-1))
