绑定元素要占用多少空间？

Question

以下代码来自我的 studentDeutils.xaml 页面。我有

<ListBox ItemsSource="{Binding}" Name="StudentDetails">
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <Grid Height="40">
                        <TextBlock Text="{Binding StudentName, StringFormat='t'}" TextWrapping="Wrap"  Margin="2,0,12,10" TextAlignment="Center"/>
                        <TextBlock Text="{Binding StudentRegNo, StringFormat='t'}" TextWrapping="Wrap" Margin="85,0,12,10" TextAlignment="Center"/>
                        <TextBlock Text="{Binding Address, StringFormat='t'}" TextWrapping="Wrap" Margin="175,0,12,10" TextAlignment="Center"/>
                        <TextBlock Text="{Binding TWD, StringFormat='t'}" TextWrapping="Wrap" Margin="365,0,12,10" TextAlignment="Center"/>
                    </Grid>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>

 <TextBlock x:Name="totalstudents" FontSize="24" TextAlignment="Center" FontWeight="Bold" Text="" TextWrapping="Wrap"  HorizontalAlignment="Left" Width="247" />

我使用来自 studentDeatils.xaml.cs 的以下代码将数据发送到 .xaml 页面。这里的 StudentDetailsViewer 类用于显示绑定文件。

foreach (var stu in Studentdetails)
                {
                    this.StudentsheetItems.Add(new StudentDetailsViewer()
                    {
                        StudentName = stu.StudentName,
                        StudentRegNo = stu.StudentRegNo,
                        Address= stu.Address,
                        TWD = stu.TWD

                    });

                };

                StudentDetails.ItemsSource = StudentsheetItems;

我想在绑定列表后查看 TextBlock(x:Name="totalstudents")。如何知道绑定Listbox会占用多少空间？

不要考虑高度，让 XAML 为你做。

<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="Auto" />
</Grid.Rowdefinitions>
<ListBox Grid.Row="0" ItemsSource="{Binding}" Name="StudentDetails">
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <Grid Height="40">
                        <TextBlock Text="{Binding StudentName, StringFormat='t'}" TextWrapping="Wrap"  Margin="2,0,12,10" TextAlignment="Center"/>
                        <TextBlock Text="{Binding StudentRegNo, StringFormat='t'}" TextWrapping="Wrap" Margin="85,0,12,10" TextAlignment="Center"/>
                        <TextBlock Text="{Binding Address, StringFormat='t'}" TextWrapping="Wrap" Margin="175,0,12,10" TextAlignment="Center"/>
                        <TextBlock Text="{Binding TWD, StringFormat='t'}" TextWrapping="Wrap" Margin="365,0,12,10" TextAlignment="Center"/>
                    </Grid>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>

 <TextBlock x:Name="totalstudents" Grid.Row="1" FontSize="24" TextAlignment="Center" FontWeight="Bold" Text="" TextWrapping="Wrap"  HorizontalAlignment="Left" Width="247" />
</Grid>
