Load sequence

I have a simple app, that loads a bunch of records in a gallery on the Start Screen.

When the user searches for records in the gallery and there are no mathcing records, I display this message:

using a formula as below on the Visible property:

If(CountRows(Gallery.AllItems) = 0, true, false)

The issue is, that the message displays when the app is loaded, because no records has been fetched by the gallery by then. Is there anyway I can set the sequence of the formulas? E.g., first run the query of the gallery - and afterwards run the formula above?

This is not possible. You could do several thinks to get this working:
1) ClearCollect() your table in a collection and add a IF() formula to control your image like:
If(!OnStartTrue, // do your sequence UpdateContext({OnStartTrue:true}) )
Then on you image.visible
OnStartTrue && CountRows(Gallery.AllItems) = 0
Yes, lose the IF() here, your condition has true/false as a result.
2. Add a timer which you tricker on the start off your app. On the Timer.End you set your variable OnStartTrue. Give it 1-2 seconds to give PowerApps the time to load the gallery.

Hope this helps.

Thanks for your input, @KroonOfficeSol.

Using a timer seems to do the job for me. Thanks.
