Hi!

So I have a gallery with different rows that shows information from SP list, and in the right side there is a button that navigates into another screen. So I want if one of the information is "Reservada", the button doesn't navigate, and if it's "Available" it navigates correctly.

How could I add that into the button?

Look how the first screen looks:

So I want that if its "Reservada", when clicking that button, doesn't navigate to next screen, just when it's Disponible.

Hi @Charlie Martharper,

OnSelect property of the button is your friend in this case. As the button sits inside the gallery, you can reference the current row using ThisItem.

If( ThisItem.Status = "Available", Navigate(DetailScreen, ScreenTransition.Fade), Notify("This item is reserved and cannot be opened.", NotificationType.Warning) // if you want any notification )

Assuming you are checking against Status column of your SP list recrod. Hence, ThisItem.Status is checking column. I have produced a similar feature for mine, i think it will help you.

Please mark as answered if it helps.

Hello @Charlie Martharper,

Please try below code:

If( ThisItem.Estat.Value = "Available", //ThisItem.Estat.Value - Replace it with your column name. Update the option according to your setup. Navigate(Dashboard_Screen,ScreenTransition.None);, //Dashboard_Screen - Replace with your screen name Notify("Already Reserved!",NotificationType.Warning) //Already Reserved! - Replace with your error message );

Hello @Charlie Martharper,

Approach 1: Here user aware and will avoid accident click
On your Button DisplayMode Property Add below formula :
If( ThisItem.Status = "Reservada", //replace with your column name DisplayMode.Disabled, DisplayMode.Edit )

OnSelect property code should be:
If( ThisItem.Status = "Reservada", Notify("Already reserved", NotificationType.Error), Navigate(DetailScreen) );

For best practice use Tooltip
If( ThisItem.Status = "Reservada", "This slot is already reserved", "Click to navigate on screen" )
Approach 2: Here the user will click, but instead of nothing happening, at least a notification should explain why they are not navigated to the screen.
If( ThisItem.Status = "Reservada", Notify("The screen will open only when the status is available.", NotificationType.Warning), // if you want any notification Navigate(DetailScreen, ScreenTransition.Fade) )

The problem is, if I click on the data, it navigates into the other screen. So if they don't click on the button, and click on the full information gallery, it will go there anyway.

Should I change this?

Ok its solved, I changed it to "false" and nothing happens.

Thanks!!

You can control this directly from the button’s OnSelect (or DisplayMode) using a simple condition based on the selected gallery item.

Assuming the status column from SharePoint is called Status and contains values like:

Reservada

Disponible

✅ Option 1 — Control navigation in OnSelect (recommended)

Set the button OnSelect to:

If( ThisItem.Status = "Disponible", Navigate(Screen2, ScreenTransition.Fade) )

When the value is Reservada, nothing happens — no navigation.

✅ Option 2 — Disable the button when it’s “Reservada”

This gives better UX because the user clearly sees it’s not clickable.

Set DisplayMode of the button:

If( ThisItem.Status = "Reservada", DisplayMode.Disabled, DisplayMode.Edit )

Navigation stays normal in OnSelect:

Navigate(Screen2, ScreenTransition.Fade)

✅ Option 3 — Combine both (best practice)

DisplayMode

If( ThisItem.Status = "Reservada", DisplayMode.Disabled, DisplayMode.Edit )

OnSelect

If( ThisItem.Status = "Disponible", Navigate(Screen2, ScreenTransition.Fade) )

This prevents navigation even if the button is triggered programmatically.

🔹 If your button is outside the gallery

Use:

Gallery1.Selected.Status

instead of ThisItem.Status.

Final behavior

Status Button

Disponible ✅ Navigates

Reservada ❌ Disabled / No navigation

This is the cleanest and most commonly used pattern in Power Apps galleries.
