【问题描述】:
我正在进行一项可行性研究,以了解我们是否以及如何将 Forms 应用程序集成到 WPF 项目中。
我从一个简单的例子开始,马上就遇到了问题(这里是代码):
<Window x:Class="TestFormsIntegration.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:wf="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms"
xmlns:local="clr-namespace:TestFormsIntegration"
mc:Ignorable="d"
Title="MainWindow" Height="450" Width="800">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="40"/>
<RowDefinition Height="*"/>
<RowDefinition Height="40"/>
</Grid.RowDefinitions>
<Label Grid.Row="0" Content="Menue Bar" HorizontalContentAlignment="Center" Background="BlanchedAlmond" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" />
<ScrollViewer x:Name="scrollViewer" Grid.Row="1" HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto">
<Grid >
<Grid.RowDefinitions>
<RowDefinition Height="200" />
<RowDefinition Height="200" />
<RowDefinition Height="200" />
<RowDefinition Height="200" />
</Grid.RowDefinitions>
<WindowsFormsHost Grid.Row="0" HorizontalAlignment="Center" Height="190" VerticalAlignment="Center" Width="250">
<wf:Button Text="Button 0" Height="180" Width="200" BackColor="Gray" />
</WindowsFormsHost>
<WindowsFormsHost Grid.Row="1" HorizontalAlignment="Center" Height="190" VerticalAlignment="Center" Width="250">
<wf:Button Text="Button 1" Height="180" Width="200" BackColor="Gray"/>
</WindowsFormsHost>
<WindowsFormsHost Grid.Row="2" HorizontalAlignment="Center" Height="190" VerticalAlignment="Center" Width="250">
<wf:Button Text="Button 2" Height="180" Width="200" BackColor="Gray" />
</WindowsFormsHost>
<WindowsFormsHost Grid.Row="3" HorizontalAlignment="Center" Height="190" VerticalAlignment="Center" Width="250">
<wf:Button Text="Button 3" Height="180" Width="200" BackColor="Gray" />
</WindowsFormsHost>
</Grid>
</ScrollViewer>
<Label Grid.Row="2" Content="Status Bar" HorizontalContentAlignment="Center" Background="Wheat" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" />
</Grid>
</Window>
在一个有 4 行的网格中,我放置了 4 个表单按钮。当我运行代码时,内部网格跨越边界并覆盖顶部和底部的标签(指示菜单和状态栏)并占据整个窗口的高度。
有谁知道这种行为以及如何解决它?
