Item in CollectionView is not highlighted if used in SwipeView ?

@Wenyan Zhang (Shanghai Wicresoft Co,.Ltd.)

Today in MAUI there is the same problem. I explain our problem, I have this layout:
<DataTemplate>

<SwipeView>

<SwipeView.BotomItems>

<Border> here inside is my layout </Border

</SwipeView>
</DataTemplate>

If I put this code

  <VisualStateManager.VisualStateGroups>
      <VisualStateGroupList>
          <VisualStateGroup x:Name="CommonStates">
              <VisualState x:Name="Selected">
                  <VisualState.Setters>
                      <Setter Property="BackgroundColor" Value="{DynamicResource primary}" />
                  </VisualState.Setters>
              </VisualState>
              <VisualState x:Name="Normal">
                  <VisualState.Setters>
                      <Setter Property="BackgroundColor" Value="{DynamicResource black025}" />
                  </VisualState.Setters>
              </VisualState>
          </VisualStateGroup>
      </VisualStateGroupList>
  </VisualStateManager.VisualStateGroups>

Before </Swipeview> It changes the backgorund underneath my layout aka border because it changes the background color of the SWIPE ! while I need to change the background color of the <Border> to see it visually in UI !

If I move the visual state before </Border> it doesn't work.

So I neet to change the visual state of my element in order that user have a visual feedback, otherwise the swipe is underneath my layout, visible only if I swipe.

SOLUTION:

Add

 <Border x:Name="RootBorder"

Then add TargetName to redirect to the desired object.

   <VisualStateManager.VisualStateGroups>
       <VisualStateGroupList>
           <VisualStateGroup x:Name="CommonStates">
               <VisualState x:Name="Selected">
                   <VisualState.Setters>
                       <Setter TargetName="RootBorder" Property="BackgroundColor" Value="Red" />
                   </VisualState.Setters>
               </VisualState>
               <VisualState x:Name="Normal">
                   <VisualState.Setters>
                       <Setter TargetName="RootBorder" Property="BackgroundColor" Value="White" />
                   </VisualState.Setters>
               </VisualState>
           </VisualStateGroup>
       </VisualStateGroupList>
   </VisualStateManager.VisualStateGroups>

Hello,

Welcome to our Microsoft Q&A platform!

I test it through the code snippet you provided, and only add the content of SwipeView and RightItems, when click CollectionView ,it is highlighted. It works in both iOS and Android, I can't reproduce this issue.

<StackLayout>  
        <CollectionView  
            SelectionMode="Single"  
            ItemsSource="{Binding SourceList}">  
            <CollectionView.ItemTemplate >  
                <DataTemplate>  
                    <SwipeView >  
                        <SwipeView.RightItems>  
                            <SwipeItems><!--add SwipeItem-->  
                                <SwipeItem Text="delete" BackgroundColor="Blue" Invoked="SwipeItem_Invoked">  
                                </SwipeItem>  
                            </SwipeItems>  
                        </SwipeView.RightItems>  
                        <StackLayout><!--add this content-->  
                            <Label Text="{Binding .}" HeightRequest="80"></Label>  
                        </StackLayout>  
                      
                    </SwipeView>  
                </DataTemplate>  
            </CollectionView.ItemTemplate>  
        </CollectionView>  
          
    </StackLayout>  

Then I try to set SwipeView background color to white, and add VisualStateManager.VisualStateGroups , it also works, you could have a try.

<CollectionView  
            SelectionMode="Single"  
            ItemsSource="{Binding SourceList}">  
            <CollectionView.ItemTemplate >  
                <DataTemplate>  
                    <SwipeView BackgroundColor="White">  
                        <SwipeView.RightItems>  
                            <SwipeItems>  
                                <SwipeItem Text="delete" BackgroundColor="Blue" Invoked="SwipeItem_Invoked">  
                                </SwipeItem>  
                            </SwipeItems>  
                        </SwipeView.RightItems>  
                        <StackLayout>  
                            <Label Text="{Binding .}" HeightRequest="80"></Label>  
                        </StackLayout>  
                        <VisualStateManager.VisualStateGroups>  
                            <VisualStateGroup Name="CommonStates">  
                                <VisualState Name="Normal" />  
                                <VisualState Name="Selected">  
                                    <VisualState.Setters>  
                                        <Setter Property="BackgroundColor" Value="Yellow" />  
                                    </VisualState.Setters>  
                                </VisualState>  
                            </VisualStateGroup>  
                        </VisualStateManager.VisualStateGroups>  
                    </SwipeView>  
                </DataTemplate>  
            </CollectionView.ItemTemplate>  
        </CollectionView>  

I'm afraid you could share more operation information, running environment and code snippets or share me a demo to test.
