Posted on by Community Power Pla... Microsoft Employee

I have a weird problem.

lets just call this Screen1 and Screen2

On Screen1:

I have a gallery that also has a button. when the button is pressed the navigation goes to Screen2.

On Screen2:

The data on screen2 is showing what row was selected in the first screen choice. and data from that row.

Problem:

For some reason after i go to screen2 from screen1 :

On screen1 the selected row is changing to another row..?? even though i'm not on that screen.

I'm trying to figure out how to stop the gallery on screen1 to stay on the row i selected.

Thanks

David

What are the Items properties of your Galleries??

If there are any complex operations (sorting, datashaping, etc.) and you are submitting any data, or you reference and controls or variables that are changed at any point from screen to screen, then the Gallery will have to re-evaluate its Items property. When it does that, it will then select the record you have in the Default property of the gallery...if you have no Default, then the first record will be selected.

That should give you some clues to look over.

I hope this is helpful for you.

I'm not doing any re-evaluation to the gallery when navigating to screen2. No "OnVisible" code(screen2). However i do have code in the "Visible" method on screen1. Refreshing the table that support the gallery.

If you are refreshing the table (something you don't need to do), then it will cause the formula to re-evaluate.

If there is no other formula in the Items property other than the data source name, then it is the refresh that is causing it.

Is there a particular need for the refresh?
