Defining a variable as a selected gallery item

Hi, I am trying to define a variable so that when you select an item from the gallery it will fill in all the fields related to this gallery. I only have experience with drop downs for creating variables. To test the connection between the data from my MS list and the power app, I used a drop down. The gallery is also populated with data from the list. I would like to define my variable as the selected list item. So something like Set(TechVar ,LookUp('Technology Register_1',Title = ThisItem.Title.Selected.Value)) but this won't work. TechVar (my variable) was previously defined for choosing from the drop down but instead of selecting my item from the drop down, I would like to select from the gallery instead. 


Any help would be greatly appreciated, Thank you in advance

Hi @Anonymous ,

You do not need all of that

Set(
   TechVar,
   ThisItem
);
Navigate(HOMEscreen)

or you can use this if you selection sources have different field content on the same list.

Set(
   TechVar,
   LookUp(
      'Technology Register_1'
      ID = ThisItem.ID
   )
);
Navigate(HOMEscreen)

Hi @Anonymous ,

I am suspecting you are setting the Variable from your drop-down to a single text value - if form the Gallery, you just need

Set(
   TechVar,
   ThisItem.YourFieldName
)

Hi @WarrenBelz this isn't working.  So when I had the dropdown, it displayed a list of all of the Title values from my MS list. These values are all present in the gallery. When the user clicks on the title from the gallery, I would like this open another screen, and fill in values. With the dropdown, I was able to fill in the values, but I would like to select a gallery item instead of using the dropdown

@Anonymous ,

What you have not posted is how you set the Variable for the drop-down - I was guessing it was a single value. If you want the whole selected record from the gallery

Set(
   TechVar,
   ThisItem
)

The proviso here though it that the Items of the Gallery and Combo Box contain the exact Table structure - if not you will get an error on this.

Set(TechvVar,LookUp('Technology Register_1',Title= Dropdown1.Selected.Value))

 

@WarrenBelz this is how i defined the variable when i had the dropdown

@Anonymous ,

Then assuming the Items of your gallery are based on the full field content 'Technology Register_1', (you have not used Add/Show/RemoveColumns ) the code I supplied last

Set(
   TechVar,
   ThisItem
)

should set the same value from your gallery.

Hi @WarrenBelz I'm not 100% sure of the meaning of full field content, so I will describe what's in the gallery, so I individually added items to the gallery rather than making a table as I only had to put a few things in. The gallery contains values for every row of the selected columns: ie. i chose to display the image column, title column, status column. To do this (for the status column for example), I used the code: 

ThisItem.Status.Value

I'm not sure if my explanation initially was clear enough, so I will restate my aim. I would like clicking on the Technology Name in the gallery to do the same thing as the dropdown - ie to look up the information related to that Technology in the MS list and display it all on the related screens 

Hi @Anonymous ,

The easiest way to explain is just to post the Items of both the gallery and combo box.

Hi @WarrenBelz 

I have got rid of the dropdown, this is the code from my gallery. This works partly as it succesfully allows me to navigate, however he variable isn't defined correctly as I can't use this variable to populate fields 

Set(TechVar ,LookUp('Technology Register_1',Name =ThisItem.IsSelected))& Navigate(HOMEscreen)

Hi @Anonymous ,

You do not need all of that

Set(
   TechVar,
   ThisItem
);
Navigate(HOMEscreen)

or you can use this if you selection sources have different field content on the same list.

Set(
   TechVar,
   LookUp(
      'Technology Register_1'
      ID = ThisItem.ID
   )
);
Navigate(HOMEscreen)
