Path from clicks

Posted on by Community Power Pla... Microsoft Employee

Hello. When I click on the recursive menu, I need to save the path and display it completely through slashes.

I have in Gallery1

Items:

Filter(Objects;CS_Parent=Text(tmp_loc.id) Or ID=Value(tmp_loc.id))

OnSelected:

UpdateContext({tmp_loc:{id:ThisItem.ID;title:ThisItem.Titel;parent:ThisItem.CS_Parent;container:ThisItem.CS_Container}});;Set(CS_Location;{id:ThisItem.ID;parent:ThisItem.CS_Parent;currentid:tmp_loc.id;title:ThisItem.Titel;path:Concatenate(CS_Location.title;" / ";tmp_loc.title)});;If(tmp_loc.container= false ;Navigate(FCamera;ScreenTransition.Cover))

In Label:

If(CS_Location.id > 0;CS_Location.path;"")

But Concatenate() does not work correctly. It builds a path only from 2 headings, inserts a slash on the first click and, when returning from another display, puts forward the final menu item. How to fix all this?

Hi @Anonymous ,

Could you please share a bit more about your issue?

Could you please share a screenshot about your app's configuration?

Based on the formula that you mentioned, I think there is something wrong with it. I have made a test on my side, please consider take a try to modify your formula as below:

Set the OnSelect property of the Gallery to following:

UpdateContext({tmp_loc:{id:ThisItem.ID;title:ThisItem.Titel;parent:ThisItem.CS_Parent;container:ThisItem.CS_Container}});;
UpdateContext( /* <-- Modify formula here. Use UpdateContext() function to store the CS_Location variable instead of Set() function */
{
CS_Location: {
id: ThisItem.ID;
parent: ThisItem.CS_Parent;
currentid: tmp_loc.id;
title: ThisItem.Title;
path: Concatenate(path; " / "; tmp_loc.title) /* <-- Concatenate tmp_loc.title value with previous stored path value */
}
}
);;
If(tmp_loc.container= false; Navigate(FCamera;ScreenTransition.Cover))

Please take a try with above solution, then check if the issue is solved.

Thanks for the decision, but it doesn't work for me. I have to transfer data to another display, so I can’t use the UpdateContext() function to display the path.

path:Concatenate(CS_Location.path;tmp_loc.title;" / ")
This is how I started working, I just need to fix it somehow. How to remove the slash at the end of the path and how to clean up if I switched from another display?

OnSelect in Gallery
UpdateContext({tmp_loc:{id:ThisItem.ID;title:ThisItem.Titel;parent:ThisItem.CS_Parent;container:ThisItem.CS_Container;path:Concatenate(tmp_loc.path;tmp_loc.title;" / ")}});;Set(CS_Location;{id:ThisItem.ID;parent:ThisItem.CS_Parent;currentid:tmp_loc.id;title:ThisItem.Titel;path:tmp_loc.path});;If(tmp_loc.container=false;Navigate(FCamera;ScreenTransition.Cover))
Text in Label
If(CS_Location.id > 0;CS_Location.path;"")
I managed to do it right. It remains to remove Undefined from the path. How can I do it?

Hi @Anonymous ,

Do you want to remove the "Undefined" text from the path?

If you want to remove the "Undefined" text from the path, I have made a test on my side, please take a try with the following workaround:

Set the Text property of the Label to following:

Concat( Filter( Split(Label1.Text, " / "), Result <> "Undefined", Result <> "" ), Result & " / " )

On your side, you should type:

If( CS_Location.id > 0; Concat( Filter( Split(CS_Location.path; " / "); Result <> "Undefined"; Result <> "" ); Result & " / " ); "" )

In addition, if you also want to remove the slash at the end of the path, please consider take a try to modify above formula as below:

If( CS_Location.id > 0; Left( Concat( Filter( Split(CS_Location.path; " / "); Result <> "Undefined"; Result <> "" ); Result & " / " ); Len(Concat(Filter(Split(CS_Location.path; " / "); Result <> "Undefined"; Result <> ""); Result & " / "))-3 ); "" )
