你好,我希望在我的WinForms应用程序中将WPF控件添加到ElementHost中。我的控件的行为如图所示。我希望扩展任何展开器都会使我的树形控件调整为较小的大小。并且在开始时,我希望我的展开器处于折叠状态。
我尝试过像这样的代码:
<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>
and:
public void AddControl(ElementHost host)
{
this.parentHost = host;
host.Child = this;
this.Height = host.Size.Height;
treeView1.MaxHeight = this.Height - 60;
}
但是它不能正常工作。另外,我希望这个控件在我调整winForms窗口大小时也能调整大小。
有人可以帮助我如何设置对齐方式等吗?
