Xamarin Forms设置Grid.Row为Auto后网格项仍显示滚动条的问题

Hey there! I get exactly where you're coming from—having each ListView scroll independently instead of the whole page can be super frustrating. Let's break down why this is happening and how to fix it.

Why Your Current Setup Isn't Working #

The core issue here is that ListView is a self-contained scrollable control by design. Even when you wrap your Grid in a ScrollView, the ListView will still prioritize its own scrolling behavior. Setting RowDefinitions="Auto" doesn't change this because the ListView will only expand to fit a certain amount of content before enabling its internal scroll.

The Solution: Use BindableLayout Instead of ListView #

To make the entire page scroll (with your ListView content fully visible), replace each ListView with a StackLayout that uses BindableLayout. This turns your list into a static part of the page layout, so the outer ScrollView can handle all scrolling.

Here's how to modify your existing code:

<!-- Wrap everything in a ScrollView first -->
<ScrollView Padding="10">
    <StackLayout>
        <!-- Your Header Label -->
        <Label Padding="20" FontAttributes="Bold" FontSize="40" Text="{Binding DisplayName}"/>

        <!-- News Section (Replaces ListView) -->
        <StackLayout>
            <!-- ListView Header becomes a regular Grid -->
            <Grid ColumnDefinitions="*,Auto" Padding="10" VerticalOptions="Center">
                <Label Text="News" Grid.Column="0" FontAttributes="Bold" FontSize="32"/>
                <Label Text="mehr Anzeigen" Grid.Column="1" HorizontalTextAlignment="End"/>
            </Grid>

            <!-- BindableLayout for the News items -->
            <StackLayout 
                BindableLayout.ItemsSource="{Binding News}"
                Padding="10">
                <BindableLayout.ItemTemplate>
                    <DataTemplate>
                        <StackLayout Padding="10">
                            <Label Text="{Binding DateTimeString}"/>
                            <Label Text="{Binding Text}" MaxLines="4"/>
                        </StackLayout>
                    </DataTemplate>
                </BindableLayout.ItemTemplate>
            </StackLayout>
        </StackLayout>

        <!-- Add your other controls (other ListViews converted similarly) here -->
    </StackLayout>
</ScrollView>

Key Notes: #

• Simplify the Layout: Since we're using a StackLayout inside the ScrollView, we don't need the Grid with RowDefinitions anymore—StackLayout handles vertical stacking automatically.
• BindableLayout Benefits: This approach renders all list items directly in the page layout, so there's no internal scrolling from a ListView. The outer ScrollView will now control scrolling for the entire page.
• Performance Check: If your News collection is very large (hundreds of items), BindableLayout might be less performant than ListView (which uses UI virtualization). For most standard use cases though, this is a perfect solution for full-page scrolling.

Why Your Earlier ScrollView Attempt Failed #

When you wrapped the Grid in a ScrollView before, the ListView still maintained its own scrollable area because it's built to virtualize content (only render what's visible on screen). By switching to BindableLayout, we're opting out of that virtualization in favor of displaying all content at once and letting the page's ScrollView handle the rest.
