如何通过 XAML 在 WPF TabControl 中添加控件

Question

我有以下XAML，一个TabControl，它绑定到一个ObservableCollection，并可以很好地创建我的标签。

<Window x:Class="BA_Auditing.AuditWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="BizeAsset - Audit Results" Height="700" Width="1120" WindowStartupLocation="CenterScreen" WindowState="Maximized">
    <Grid>
        <TabControl Name="ModuleTabControl" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="5" ItemsSource="{Binding}" >
            <TabControl.ItemTemplate>
                <DataTemplate>
                    <TextBlock>                            
                        <TextBlock Text="{Binding DISPLAY_NAME}"/>
                    </TextBlock>
                </DataTemplate>
            </TabControl.ItemTemplate>

            <TabControl.ContentTemplate>
                <DataTemplate>
                    <Grid>
                        <Grid.RowDefinitions>
                            <RowDefinition />
                            <RowDefinition Height="Auto" />
                            <RowDefinition />
                        </Grid.RowDefinitions>
                        <Grid Grid.Row="0">
                            <Grid.ColumnDefinitions>
                                <ColumnDefinition />
                                <ColumnDefinition />
                            </Grid.ColumnDefinitions>
                            <TextBlock Grid.Column="0" Text="Search:" HorizontalAlignment="Right"/>
                            <TextBox x:Name="tbxSearch" Grid.Column="1"/>
                        </Grid>
                        <TextBlock Grid.Row="2" Text="Items Selected: 0 of 908" />
                    </Grid>
                </DataTemplate>
            </TabControl.ContentTemplate>
        </TabControl>
    </Grid>
</Window>

接下来，我想用下一级控件填充每个选项卡区域，其中包括 Label、TextBox 另一个 TabControl 和 TextBlock。

我之前在WinForms 中写过这个，它看起来是这样的：

我需要添加什么XAML 才能做到这一点？
那是因为我是通过绑定动态设计它，而不是直接添加TabItem

[编辑]
我尝试在TabControl.ContentTemplate 中输入控件，但是 TabItem 的正文中没有显示任何内容。

Answer 1

我认为，如果您“单击”了 "WW - Wastewater" 选项卡，您会看到正在生成的内容（搜索框等） - 这是因为默认情况下未选择该选项卡。

无论如何，这里有一些代码可以让您更接近您想要的 - 这只是为了让您开始，您需要添加其他管道代码（更改通知等）。

我不知道您打算在“服务”标签等中拥有什么......所以不知道您是否可以以相同的方式处理它们，即作为“资产”。此外，您可能希望明确定义网格列的名称，而不是让它们自动生成 - 您可以在其他地方找到一些技术来做到这一点。
