Problem with OnSelect event of itens inside a gallery

Posted on by fuba

Hello everybody, I'm setting up a dynamic menu using an array in the OnStart event of my app, and I want that when I click on one of the buttons of my menu the user is directed to a new screen, but every time I click on the buttons a gray bar appears on top of it and does not perform any action. Does anyone have an idea what this is?

This is my array:

ClearCollect(
 arrMenu;
 {
 Car: "Master";
 Plate: "AZK-1765";
 Icon: renault
 };
 {
 Car: "Partner";
 Plate: "RHO-1D14";
 Icon: peugeot
 };
 {
 Car: "Onix";
 Plate: "RHT-8J32";
 Icon: chevrolet
 };
 {
 Car: "Gol";
 Plate: "BCJ-9761";
 Icon: volkswagen
 };
 {
 Car: "Bongo";
 Plate: "BDM-6G86";
 Icon: kia
 };
 {
 Car: "Versa";
 Plate: "BAY-5506";
 Icon: nissan
 }
)

And these is my buttons when I press them:

What is the code in the OnSelect property for each button?

I don't have multiple button objects in the gallery, it's just one, as the gallery uses the array as a data base and creates it on the screen as each item is named.

In my OnSelect I only have the basics of the Navigate command

These are my gallery components:

I understand, but what does the Navigate command look like? Normally in this instance you would either need to provide a reference to the screen you want to navigate to in the collection or a Switch that keys off the property of the selected item. I don't see a reference to a screen in the collection so did you use a switch or a nested if to select where to navigate?

I see, I used Navigate as follows: Navigate(EditScreen; ScreenTransition.Cover)
I just tried putting the 'Target' property for my items inside the collection with the value of the screen name 'EditScreen' and replaced it in Navigate, but the bug persists. Not sure if this is what you suggested in your comment above.

Do you have a different screen for each auto? Or is it a single EditScreen, but choosing a specific button should load a particular record in the edit screen? If its a different screen then you should do something like this

ClearCollect( myMenu, Table( { MenuLabel: "Timesheets", MenuIcon: Icon.Clock, MenuScreen: TimeEntry, MenuID: 1 }, { MenuLabel: "Projects", MenuIcon: Icon.Database, MenuScreen: Projects, MenuID: 2 }, { MenuLabel: "Tasks", MenuIcon: Icon.Check, MenuScreen: Tasks, MenuID: 3 }, { MenuLabel: "Expenses", MenuIcon: Icon.Money, MenuScreen: Expenses, MenuID: 4 }, { MenuLabel: "Clients", MenuIcon: Icon.People, MenuScreen: Clients, MenuID: 5 }, { MenuLabel: "Reports", MenuIcon: Icon.DocumentPDF, MenuScreen: Reports, MenuID: 5 }, { MenuLabel: "Exit", MenuIcon: Icon.Cancel, MenuScreen: Exit, MenuID: 6 } ) );

where the menuScreen property has an actual reference to the screen. If its a single edit form then you need to do something with the choice to tell the form which record to load.

Yes, it would be the same screen but the difference is that depending on the car model I select, I change values of two global variables to the values of 'Car' and 'Plate', which are in the collection.
I also tried to navigate to other screens, without forms, but the result is the same, I click on the button and all I see is this gray line on it, like in the image of the main question

I just tried something different, I put the Navigate in the OnSelect event of my label, where I have the name of the car and its license plate, and it worked as expected.
The question that remains is why is there this problem with a button component?

if the form is on the same screen then you don't use a Navigate. In that case the OnSelect for the button should be used to set those two variables based on which button was selected.
