找不到WindowsFormsHost错误IsRedirected吗? [英] WindowsFormsHost error IsRedirected is not found?

问题描述

我正在使用WPF项目添加WINFORM图表

I am adding a WINFORM chart to my WPF project using

 System.Windows.Forms.Integration.WindowsFormsHost

我正在尝试解决空域"渲染问题，在该问题中，主机始终被渲染为窗口的最顶层元素.我正在使用集的解决方法

I am trying to work around the "airspace" rendering issue where the host is always rendered as the top most element the window. The workaround I am using sets

IsRedireced = "true"

当我将其插入我的XMAL代码时:

When I insert this into my XMAL code:

        <Grid x:Name="ssCurveChartGrid" Grid.Column="1" Margin="110,30,160,306" Grid.ColumnSpan="4" RenderTransformOrigin="0.479,0.186">
        <WindowsFormsHost IsRedirected =" "true">

        </WindowsFormsHost>
    </Grid>

或我后面的代码:

System.Windows.Forms.Integration.WindowsFormsHost host =
            new System.Windows.Forms.Integration.WindowsFormsHost();

host.IsRedirected = "true";

我收到以下错误:

在类型"WindowsFormsHost"中找不到属性"IsRedirected"

The property 'IsRedirected' was not found in type 'WindowsFormsHost'

以下是屏幕截图:

任何人都可以帮助解释为什么会这样吗?我需要在WINFORM图表上方显示一个元素！

Can anyone help explain why this is happening? I relay need to display an element on top of my WINFORM chart!

谢谢

代码摘自MSDN站点: http://msdn.microsoft. com/en-us/library/ms752027.aspx

Code was taken from MSDN site: http://msdn.microsoft.com/en-us/library/ms752027.aspx

从MSDN: 默认情况下，可见的WindowsFormsHost元素总是绘制在其他WPF元素之上，并且不受z顺序的影响.要启用z顺序，请将WindowsFormsHost的IsRedirected属性设置为true，并将CompositionMode属性设置为Full或OutputOnly. 要查看默认的z顺序行为"

From MSDN: "By default, visible WindowsFormsHost elements are always drawn on top of other WPF elements, and they are unaffected by z-order. To enable z-ordering, set the IsRedirected property of the WindowsFormsHost to true and the CompositionMode property to Full or OutputOnly. To see the default z-order behavior"

将以下XAML复制到Grid元素中."

"Copy the following XAML into the Grid element."

<!-- Z-order demonstration. -->
<Canvas Grid.Row="1" Grid.Column="1">
  <WindowsFormsHost Canvas.Top="20" Canvas.Left="20" Background="Yellow">
    <wf:Button Text="Windows Forms control" FlatStyle="Flat"/>
  </WindowsFormsHost>
  <Label Content="A WPF label" FontSize="24"/>
</Canvas>

Press F5 to build and run the application. The WindowsFormsHost element is painted over the label element.

在IsRedirected为true时查看z顺序行为"

"To see the z-order behavior when IsRedirected is true"

Replace the previous z-order example with the following XAML.
XAML

<!-- Z-order demonstration. -->
<Canvas Grid.Row="1" Grid.Column="1">
  <WindowsFormsHost IsRedirected="True" CompositionMode="Full" Canvas.Top="20" Canvas.Left="20" Background="Yellow">
    <wf:Button Text="Windows Forms control" FlatStyle="Flat"/>
  </WindowsFormsHost>
  <Label Content="A WPF label" FontSize="24"/>
</Canvas>

Press F5 to build and run the application. The label element is painted over the WindowsFormsHost element.
