我的扩展菜单

您好我希望在我的 WinForms 应用程序中将 WPF 控件添加到 ElementHost。我的控件的行为如图所示。我希望扩展任何扩展器使我的树视图控件调整为更小的尺寸。一开始我希望我的扩展器可以折叠起来。

我正在尝试这样的事情:

<UserControl x:Class="LeftPane"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
         xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
         mc:Ignorable="d" >
<Grid VerticalAlignment="Stretch" Margin="3,3,3,3">
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="*"/>            
    </Grid.RowDefinitions>
    <TreeView Grid.Row="0" Name="treeView1" VerticalAlignment="Stretch" >

    </TreeView>
    <StackPanel  Grid.Row="1" Name="StackPanel1" VerticalAlignment="Bottom">
        <ListBox SelectedIndex="1">
            <ListBoxItem VerticalAlignment="Stretch">
                <Expander Grid.Row="1" ExpandDirection="Down" Header="expander1" VerticalAlignment="Stretch" Name="expander1" IsExpanded="False">
                    <ListBox>
                        <ListBoxItem Content="Unit 1"/>
                        <ListBoxItem Content="Unit 2"/>
                    </ListBox>
                </Expander>
            </ListBoxItem>
            <ListBoxItem VerticalAlignment="Stretch">
                <Expander Grid.Row="2" ExpandDirection="Down" Header="expander2" VerticalAlignment="Stretch" Name="expander2" IsExpanded="False">
                    <ListBox>
                        <ListBoxItem Content="Unit 1"/>
                        <ListBoxItem Content="Unit 2"/>
                    </ListBox>
                </Expander>
            </ListBoxItem>
        </ListBox>
    </StackPanel>
</Grid>

和:

public void AddControl(ElementHost host)
    {
        this.parentHost = host;
        host.Child = this;
        this.Height = host.Size.Height;
        treeView1.MaxHeight = this.Height - 60;

    }

但它不能正常工作。更重要的是,我希望在调整 winForms 窗口大小时调整此控件的大小。

谁能帮助我如何设置对齐等。

这就是我实现这一目标的方式......首先,我将其更改Grid为以下内容:

<Grid.RowDefinitions>
    <RowDefinition Height="*" />
    <RowDefinition Height="Auto" />
    <RowDefinition Height="Auto" />
</Grid.RowDefinitions>

这将为两个Expander控件提供所需的空间以及TreeView其余所有控件:

<TreeView Grid.Row="0" Name="treeView1" />
<Expander Grid.Row="1" Header="expander1" Name="expander1" IsExpanded="False">
    <ListBox>
        <ListBoxItem Content="Unit 1"/>
        <ListBoxItem Content="Unit 2"/>
    </ListBox>
 </Expander>
<Expander Grid.Row="2" Header="expander2" Name="expander2" IsExpanded="False">
    <ListBox>
        <ListBoxItem Content="Unit 1"/>
        <ListBoxItem Content="Unit 2"/>
    </ListBox>
 </Expander>

为了使我的控件可调整大小,我将 ElementHost 属性 Dock 切换为 Fill。
