FILTER IMAGE GALLERY - AZURE BLOB STORAGE

[KQ]

Hi there!

I have managed to follow Shaun Young's great tutorial to create a gallery that stores and displays photos using Azure blob storage.

However, I don't want to show every photo in the collection - just the photos relating to the particular job number reference.

This is the OnSelect for the button to save the photos (using the AddPicture control):

AzureBlobStorage.CreateFile("powerappsphotos",Concatenate(DataCardValue2.Text,TextInput4_1.Text),AddMediaButton1_1)

This enables the photo filename to begin with the relevant job number (ie. DataCardValue2.Text).  All good so far.

I have created another screen with the photo gallery itself, and it displays photos from the blob storage correctly

Screen 2: OnVisible: ClearCollect(CollectFiles,AzureBlobStorage.ListFolderV2("JTJmcG93ZXJhcHBzcGhvdG9z").value

But it displays all the photos in that blob storage container.

How can I make the gallery display only photos with filename that begins with the DataCardValue2.Text?

Perhaps I am going about this the wrong way - and I should be creating a new collection instance each time, that refers to the DataCardValue2.Text?

Either way, this is beyond my capabilities, so hoping you can help or send me in the right direction.

Many thanks in advance.

Hi @KQ ,

Do you want to filter the Blob metadata collection based on DataCardValue2.Text?

I've searched the structure of BlobMetadata:

Name	Path	Type	Description
Id	Id	string	The unique id of the file or folder.
Name	Name	string	The name of the file or folder.
DisplayName	DisplayName	string	The display name of the file or folder.
Path	Path	string	The path of the file or folder.
LastModified	LastModified	date-time	The date and time the file or folder was last modified.
Size	Size	integer	The size of the file or folder.
MediaType	MediaType	string	The media type of the file or folder.
IsFolder	IsFolder	boolean	A boolean value (true, false) to indicate whether or not the blob is a folder.
ETag	ETag	string	The etag of the file or folder.
FileLocator	FileLocator	string	The filelocator of the file or folder.

Try this formula:

Filter(CollectFiles,StartsWith(DataCardValue2.Text,Name))

 Here's a doc about this api for your reference:

how did you do this ? 

I have almost same case. But i simply have a textinput and a gallery. I want to insert some text then display images in the gallery based on the text thats inserted into the textfield, but i want to make a startswith filter. So show all images that startswith "example string"
