Filter gallery to only show record for current user - SP list

[Flockters]

Hi, I have been on numerous forums & watched a number of videos but still struggling! I have an app which is linked to a SharePoint list with over 1400 employees. I have developed the app based on the 'out of the box' phone layout template that comes already set up with various functions & pages.
My query is how do I filter the gallery to only show the record for the current user? I am aware there could b delegation issues due to the size of the SP list.
The code which was already populated in BrowseGallery1 – Items = SortByColumns(Filter([@'OE Asset Register - Staff Data'], StartsWith(Title, TextSearchBox1.Text)), "Title", If(SortDescending1, Descending, Ascending))
Thanks

Hi @Flockters 

To configure this, you can follow:

1) Set a variable to get the current user details:

App -> OnStart -> Set(MyDetails, User())

Note: If you are in edit mode, select the three dots on the left menu and select "Run OnStart". This will populate the value for current session and this variable will automatically set when the app is played or refreshed.

2) Update the expression on the gallery control Items to:

SortByColumns(Filter([@'OE Asset Register - Staff Data'],ColumntoSearch = MyDetails.FullName && StartsWith(Title, TextSearchBox1.Text)), "Title", If(SortDescending1, Descending, Ascending))

Here I assumed that you have a single line of text column which stores the name of the users. 

If this a person type column:

SortByColumns(Filter([@'OE Asset Register - Staff Data'],ColumntoSearch.DisplayName = MyDetails.FullName && StartsWith(Title, TextSearchBox1.Text)), "Title", If(SortDescending1, Descending, Ascending))

Hope this Helps!

Consider leveraging User() to help you here. This is an out of the box PowerApps function that returns useful contextual information about the current user that is using the app. If any of the below is in common with one your columns, you can try and filter by this information and it is a handy way to use the current user's contextual info - including even to possibly filter your SharePoint List by this information.

https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/functions/function-user

Returns information about the current user.

Description

The User function returns a record of information about the current user:

Property Description

User().Email	Email address of the current user.
User().FullName	Full name of the current user, including first and last names.
User().Image	Image of the current user. This will be an image URL of the form "blob:identifier". Set the Image property of the Image control to this value to display the image in the app.
