How to display several groups of photos on a page and facillitate multi-select across groups

Question

In our app, we have created a Gallery style of page where we can display several groups of photos, say, grouped by date. We must deal with a variable number of dates and each date can have one or more photos.

Currently we display the photos for each Date in it's own FlexLayout row. This is managed in code. A FlexLayout row is created for each Date that we have photos for and then the Photos for the row are added to it. This works for us.

We have a new requirement to perform a multi-select of the desired photos from all the photos available. We need to indicate which photos have been selected either by putting a check in a box or changing a border color - or some other method.

Is there a way to accomplish this using a FlexLayout? Or do we need to switch to something like a CollectionView?

Can this be done all in Xaml or do we need to use Code to work with the variable nature of the number of Dates (rows) and number of Photos for a Date.

Thanks!

Hello,​

Welcome to our Microsoft Q&A platform!

do we need to switch to something like a CollectionView?

Yes, I recommend you to use CollectionView to achieve it. If you have lots of data in the your view model, FlexLayout cannot meet the performance requirements, it will have some OOM issue.

I wrote a demo about your needs, here is running screenshot. All of the code use MVVM to achieve it.

You can use this xaml layout. I use SelectionChangedCommand get the selectionItems, then use ItemsLayout="VerticalGrid, 3" to achieve the Gallery style

   <CollectionView   
                           x:Name="cvTagsCollectionView"  
                           ItemsSource="{Binding Animals}"    
                           ItemsLayout="VerticalGrid, 3"  
                           SelectionMode="Multiple"  
                           SelectionChangedCommand="{Binding SelectItemCommand}"  
                           SelectionChangedCommandParameter="{Binding  Source={x:Reference cvTagsCollectionView}}"  
                           IsGrouped="true" >  
     
               <CollectionView.GroupHeaderTemplate>  
                   <DataTemplate>  
                       <Label Text="{Binding Name}"  
                              BackgroundColor="LightGray"  
                              FontSize="Large"  
                              FontAttributes="Bold" />  
                   </DataTemplate>  
               </CollectionView.GroupHeaderTemplate>  
     
                 
               <CollectionView.ItemTemplate>  
                   <DataTemplate>  
                       <Grid Padding="10">  
                           <Grid.RowDefinitions>  
                               <RowDefinition Height="Auto" />  
                               <RowDefinition Height="Auto" />  
                           </Grid.RowDefinitions>  
                           <Grid.ColumnDefinitions>  
                               <ColumnDefinition Width="Auto" />  
                               <ColumnDefinition Width="Auto" />  
                           </Grid.ColumnDefinitions>  
                           <Image   
                                  Grid.RowSpan="2"   
                                  Source="{Binding ImageUrl}"   
                                  Aspect="AspectFill"  
                                  HeightRequest="60"   
                                  WidthRequest="60" />  
                            
                            
                       </Grid>  
                   </DataTemplate>  
               </CollectionView.ItemTemplate>            
           </CollectionView>  

Here is layout's background code.

   public MainPage()  
           {  
               InitializeComponent();  
               BindingContext = new GroupedAnimalsViewModel();  
           }  

Here is my GroupedAnimalsViewModel.cs. we can get selection items from SelectItemCommand.

Manx cats come in all coat colours and patterns, though all-white specimens are rare, and the coat range of the original stock was more limited. Long-haired variants are sometimes considered a separate breed, the Cymric. Manx are prized as skilled hunters, and thus have often been sought by farmers with rodent problems, and been a preferred ship's cat breed. They are said to be social, tame and active. An old local term for the cats on their home island is stubbin. Manx have been exhibited in cat shows since the 1800s, with the first known breed standard published in 1903.",
