如何在ButtonClick上更改DataTemplate中的StackLayout高度？ （Xamarin）

Question

任何人都可以帮我吗？我正在尝试创建一个代码，该代码将在单击“查看更多”按钮时扩展标签。我为此写了DataTemplate，按钮和堆栈（我只需要在堆栈内部扩展标签）都位于DataTemplate中。我该怎么做？预先感谢您的回答！

这里是XAML：

<ContentPage.Resources>
        <DataTemplate x:Key="SollicitatietipsTipTemplate" x:Name="SollicitatietipsTipTemplateName">
            <ScrollView>
                <StackLayout Spacing="10">
            <Frame  CornerRadius="5" BorderColor="#717171" Opacity="50"  BackgroundColor="Transparent" Padding="0,0,0,0" Margin="0,5,0,5">
                <Grid RowSpacing="0">
                    <Grid.RowDefinitions>
                        <RowDefinition Height="40"></RowDefinition>
                        <RowDefinition Height="112" x:Name="row1"></RowDefinition>
                        <RowDefinition></RowDefinition>
                    </Grid.RowDefinitions>
                    <StackLayout Grid.Row="0" Orientation="Horizontal" >
                        <Label TextColor="#474747" Text="1. Title Tip" FontSize="Large"  Margin="5,5,0,0"></Label>          
                    <StackLayout Grid.Row="1" Spacing="0" x:Name="TextStack" >
                        <Label HeightRequest="89" Padding="5,5,5,0" Margin="5,0,0,0" Grid.Row="1" Text="Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

                        <Grid>
                            <Grid.ColumnDefinitions>
                                <ColumnDefinition x:Name="column1"  Width="80"></ColumnDefinition>
                                <ColumnDefinition ></ColumnDefinition>
                            </Grid.ColumnDefinitions>
                            <Grid.RowDefinitions>
                                <RowDefinition Height="15"></RowDefinition>
                            </Grid.RowDefinitions>
                            <Button Padding="7,0,0,0" Grid.Column="0" Clicked="buttonmore_Clicked" BackgroundColor="Transparent" x:Name="buttonmore" Text="lees meer..." FontAttributes="Italic"  TextColor="#439aff"  Margin="2,0,0,0"></Button>
                        </Grid>
                    </StackLayout>
                </Grid>
            </Frame>
                </StackLayout>
            </ScrollView>
        </DataTemplate>
    </ContentPage.Resources>
