all clear to me now @Open1333. As I understand it, you do not want specific Gallery items to "appear" selected visually.

 

On the FontWeight property for each Label control in your Gallery, use:

 

If(
    ThisItem.IsSelected && ThisItem.NumberofUnits <> 0,
    FontWeight.Semibold,
    FontWeight.Normal
)

 

 

For the Rectangle, use the below on the Visible property:

 

ThisItem.IsSelected  && ThisItem.NumberofUnits <> 0

@Open1333 depends on what you're trying to do.

 

You cannot disable specific items in a Gallery, but you can apply a condition to do or not do something. For example you could apply a condition on a Button embedded inside the Gallery to be disabled if a condition is met. Or you could prevent a user from undertaking a specific action when they click on a specific Gallery item.

 

Again, the answer depends on what you want to do so please provide more detail.

Hi @Amik,

 

I am trying to prevent the gallery item not being able to select when ThisItem.NumberofUnits = 0.

is it possible?

@Open1333 you have repeated the same question. As already stated, this is not possible.

 

You can make the Gallery Item "appear" disabled by updating the TemplateFill property to e.g.

 

If(
    ThisItem.NumberofUnits  = 0,
    Color.Gray,
    Color.Transparent
)

 

 

However, I do not know what your goal is.

 

  1. Why do you want to prevent the Gallery from being selected?
  2. What should not happen if the user selects an item from the Gallery?

Hi @Amik 

 

1. Why do you want to prevent the Gallery from being selected?

I want to prevent the gallery from being selected because i do not want the items to be highlighted when the item is 0.

 

Right now when selected:

2. What should not happen if the user selects an item from the Gallery?

 

Below is the outcome i wanted when item is 0 it should not be highlighted.

@Open1333 - the Rectangle, not the Gallery.

Hi @Amik ,

 

Many apologies for the late reply,

 

I entered the code into the rectangle visible property, the outcome is still the same.

ThisItem.IsSelected  && ThisItem.NumberofUnits <> 0
