Xamarin, How can i contain the first batch of list of rows and columns with a border, like group them together? - xamarin

Question

I've been trying to put border on these text and the only way i can is taking off grid on every row so now it has borders but then the grid frame is off. I can't differentiate which part is from row1 or the beginning of list.
<StackLayout>
<Label Text="rain Log" VerticalOptions="Center" HorizontalOptions="Center" Margin="0,50,0,0" />
<ListView x:Name="postListView" >
<ListView.ItemTemplate>
<!-- from the post.cs -->
<DataTemplate>
<ViewCell >
<Grid BackgroundColor="Black" HorizontalOptions="CenterAndExpand" VerticalOptions="FillAndExpand">
<Grid.RowDefinitions > <!-- 8 rows -->
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="120"/>
<ColumnDefinition Width="100"/>
</Grid.ColumnDefinitions>
<!-- Row 1 -->
<Label Grid.Row="1" FontSize="Medium" Grid.Column="0" Text="right tst:" HorizontalTextAlignment="Start" BackgroundColor="cornflowerblue" />
<Label Grid.Column="1" Grid.Row="1" Text="{Binding drain1vol}" BackgroundColor="cornflowerblue"/>
<!-- endrow1 -->
<!-- rain1 Row 1 -->
<Label Grid.Row="2" Grid.Column="0" Text="nothing" BackgroundColor="Yellow"/>
<Label Grid.Row="2" Grid.Column="1" Text="{Binding drain2vol}"
HorizontalTextAlignment="Center" BackgroundColor="Yellow" />
<!-- endrow1 -->
</Grid>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</StackLayout>

what i want

Answer 1

If you want to separate out your item as like group than you can use SeparatorColor and its visibility.
Instead of 2 boxview you can also use one grid as wrapper and using ColumnSpacing and RowSpacing.
<ListView x:Name="postListView" SeparatorVisibility="Default" HasUnevenRows="True" ItemsSource="{Binding Items}" SeparatorColor="White">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<Grid BackgroundColor="Black" HorizontalOptions="CenterAndExpand"
VerticalOptions="FillAndExpand" Padding="1,2,1,0">
<Grid HorizontalOptions="CenterAndExpand"
VerticalOptions="FillAndExpand" ColumnSpacing="1" RowSpacing="1">
<Grid.RowDefinitions >
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="120"/>
<ColumnDefinition Width="100"/>
</Grid.ColumnDefinitions>
<Label Grid.Row="0" FontSize="Medium" Grid.Column="0" Text="right tst:" HorizontalTextAlignment="Start" BackgroundColor="cornflowerblue" />
<Label Grid.Column="1" Grid.Row="0" Text="{Binding drain1vol}" HorizontalTextAlignment="Center" BackgroundColor="cornflowerblue"/>
<Label Grid.Row="1" Grid.Column="0" Text="nothing" BackgroundColor="Yellow"/>
<Label Grid.Row="1" Grid.Column="1" Text="{Binding drain2vol}" HorizontalTextAlignment="Center" BackgroundColor="Yellow" />
</Grid>
</Grid>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>

Answer 2

Yes, you can use BoxView to achieve this function, try the following code :
<StackLayout>
<Label Text="rain Log" VerticalOptions="Center" HorizontalOptions="Center" Margin="0,50,0,0" />
<ListView x:Name="postListView" HasUnevenRows="True">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell >
<Grid HorizontalOptions="CenterAndExpand" VerticalOptions="FillAndExpand" ColumnSpacing="2" RowSpacing="0" BackgroundColor="Black">
<Grid.RowDefinitions >
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="120"/>
<ColumnDefinition Width="100"/>
</Grid.ColumnDefinitions>
<Label Grid.Row="0" FontSize="Medium" Grid.Column="0" Text="right tst:" HorizontalTextAlignment="Start" BackgroundColor="cornflowerblue" />
<Label Grid.Column="1" Grid.Row="0" Text="{Binding drain1vol}" HorizontalTextAlignment="Center" BackgroundColor="cornflowerblue"/>
<!-- thin separator -->
<BoxView Color="Black" Grid.Row="0" Grid.ColumnSpan="2" HeightRequest="2" VerticalOptions="End" HorizontalOptions="FillAndExpand" />
<Label Grid.Row="1" Grid.Column="0" Text="nothing" BackgroundColor="Yellow"/>
<Label Grid.Row="1" Grid.Column="1" Text="{Binding drain2vol}" HorizontalTextAlignment="Center" BackgroundColor="Yellow" />
<!-- thick separator -->
<BoxView Color="Black" Grid.Row="3" Grid.ColumnSpan="2" HeightRequest="5" VerticalOptions="End" HorizontalOptions="FillAndExpand" />
</Grid>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</StackLayout>
The effect is as follows:

Answer 3

use a BoxView overlaid on your Grid to simulate a separator
<Grid HorizontalOptions="CenterAndExpand" VerticalOptions="FillAndExpand">
<!-- Row 1 -->
<Label Grid.Row="1" FontSize="Medium" Grid.Column="0" Text="right tst:" HorizontalTextAlignment="Start" BackgroundColor="cornflowerblue" />
<Label Grid.Column="1" Grid.Row="1" Text="{Binding drain1vol}" BackgroundColor="cornflowerblue"/>
<! thin separator -->
<BoxView Color="Black" Grid.Row="1" Grid.ColumnSpan="2" HeightRequest="2" VerticalOptions="End" HorizontalOptions="FillAndExpand" />
<!-- rain1 Row 1 -->
<Label Grid.Row="2" Grid.Column="0" Text="nothing" BackgroundColor="Yellow"/>
<Label Grid.Row="2" Grid.Column="1" Text="{Binding drain2vol}"
HorizontalTextAlignment="Center" BackgroundColor="Yellow" />
<! thick separator -->
<BoxView Color="Black" Grid.Row="2" Grid.ColumnSpan="2" HeightRequest="5" VerticalOptions="End" HorizontalOptions="FillAndExpand" />
</Grid>
