Canvas in PBI show always all records

[DiePic]

Hi all

I'm creating my 1st write back PBI-->PApps.

I create a canvas on my excel file from PApps and it's working for insert, modify and delete.

I insert the canvas in my PBI report and it's working.

The problem is the view, the gallery shows always all record and if I insert some data in the textboxsearch, all data disapears.

This is my formula in the gallery:
If(
  IsBlank(TextSearchBox1.Text);
  SortByColumns(
    Search([@TDipendentiTktRest]; TextSearchBox1.Text; "Dipendente"; "IdDipendente"; "InForza");
    "Dipendente";
    If(SortDescending1; SortOrder.Descending; SortOrder.Ascending)
  );
  Filter(
  [@TDipendentiTktRest];
  Dipendente = TextSearchBox1.Text   // 'PowerBIIntegration'.Data = true
  )
)
the 1st block is working but the final filter dont retrieve records ... I try also with "'PowerBIIntegration'.Data = true" (now remmed) but it return errors.
Where I'm in wrong?
Any help or suggestion will be apprecied.
Thanks in advance

HI @lbendlin thanks for your reply.
I create the PowerApp with a model, and is working well.

Then I've create my PBI and integrate the PowerApp in it.
It's working inside PBI too, but if I select the row on PBI, all records are displayed in the gallery.
In the screenshot I've selected the 2nd row but in the PowerApp there are all rows.
I've seen several post that selecting a row on the left, the same is reported on the PowerApp.

I've tryed to modify the formula on the gallery but it's not working, if I use the TextBox to search a name, the gallery visualization became blank.
Thanks for any suggestion or idea

Unfortunately that will not work.  Has to be the other way round.  You MUST create the PowerApp from inside the Power BI visual.

For sure?
All it's working well (insert, modify, delete), only the gallery it's not working correctly ....

Please provide more details on your setup.  Are you using a PowerApps visual in Power BI?  Did you create the PowerApp through it? Did you add the required Power BI fields to the visual? Can you see them in the PowerApps designer?
