列定义中的另一个 Window

Question

我的项目中有 2 个 Window。其中一个是 MainWindow.xaml，另一个是 Control_Page.xaml。我想将控制页 Window 插入到 ColumnDefinition 和 RowDefinition。此定义定义在 MainWindow.

这是我的代码：

<Grid x:Name="Grid_Main" SnapsToDevicePixels="True">
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="312*"/>
        <ColumnDefinition Width="353*"/>
        <ColumnDefinition Width="351*"/>
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
        <RowDefinition Height="187*"/>
        <RowDefinition Height="187*"/>
        <RowDefinition Height="186*"/>
        <RowDefinition Height="178*"/>
    </Grid.RowDefinitions>

    <Grid Grid.Column="0" Grid.Row="0" Margin="0"/>
    <Grid Grid.Column="1" Margin="0"/>
    <Grid Grid.Column="2" Margin="0"/>
    <Grid Margin="0" Grid.Row="1"/>
    <Grid Grid.Column="1" Margin="0" Grid.Row="1">
        <Button Content="Button" Margin="0" HorizontalAlignment="Center" VerticalAlignment="Center"/>
    </Grid>
    <Grid Grid.Column="2" Margin="0" Grid.Row="1">
        <Button x:Name="button1" Content="Button" HorizontalAlignment="Center" Margin="0" VerticalAlignment="Center"/>
    </Grid>
    <Grid Margin="0" Grid.Row="2"/>
    <Grid Grid.Column="1" Margin="0" Grid.Row="2"/>
    <Grid Grid.Column="2" Margin="0" Grid.Row="2"/>
    <Grid Margin="0" Grid.Row="3"/>
    <Grid Grid.Column="1" Margin="0" Grid.Row="3"/>
    <Grid Grid.Column="2" Margin="0" Grid.Row="3"/>
</Grid>

我被称为 Control_Page 的 Var。然后尝试作为 Children 到 Main Window 但它不起作用。

我试过这个不能解决这个问题。

隐藏代码；

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();

        var newWindow = new Control_Page();
        Grid.SetRow(newWindow, 0);
        Grid.SetColumn(newWindow, 0);
        Grid_Main.Children.Add(newWindow);
    }
}

无法将 window 作为另一个 window 的子项插入，您最终会遇到 {"Window must be the root of the tree. Cannot add Window as a child of Visual."} 异常。

您可以将 Control_Page.xaml 作为 UserControl 添加到您的网格中。因此，请确保在该 .xaml 文件（以及相应的 .cs 文件）

中将类型从 Window 更改为 UserControl

<Grid x:Name="Grid_Main" SnapsToDevicePixels="True">
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="312*"/>
        <ColumnDefinition Width="353*"/>
        <ColumnDefinition Width="351*"/>
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
        <RowDefinition Height="187*"/>
        <RowDefinition Height="187*"/>
        <RowDefinition Height="186*"/>
        <RowDefinition Height="178*"/>
    </Grid.RowDefinitions>

    <Control_Page Grid.Column="0" Grid.Row="0" />

    <Grid Grid.Column="0" Grid.Row="0" Margin="0"/>
    <Grid Grid.Column="1" Margin="0"/>
    <Grid Grid.Column="2" Margin="0"/>
    <Grid Margin="0" Grid.Row="1"/>
    <Grid Grid.Column="1" Margin="0" Grid.Row="1">
        <Button Content="Button" Margin="0" HorizontalAlignment="Center" VerticalAlignment="Center"/>
    </Grid>
    <Grid Grid.Column="2" Margin="0" Grid.Row="1">
        <Button x:Name="button1" Content="Button" HorizontalAlignment="Center" Margin="0" VerticalAlignment="Center"/>
    </Grid>
    <Grid Margin="0" Grid.Row="2"/>
    <Grid Grid.Column="1" Margin="0" Grid.Row="2"/>
    <Grid Grid.Column="2" Margin="0" Grid.Row="2"/>
    <Grid Margin="0" Grid.Row="3"/>
    <Grid Grid.Column="1" Margin="0" Grid.Row="3"/>
    <Grid Grid.Column="2" Margin="0" Grid.Row="3"/>
</Grid>
