在WPF C#中禁用自定义父级时启用子控件

您好，我为缩放Picture定制了父控件.在该控件内有子画布，在画布内有子图像控件.我创建了一个用于缩放和图像测量的菜单.我还可以测量图像的坐标.我禁用父级ZoomBorder控件时遇到的问题是我无法触发Child Image事件.我可以禁用名为ZoomBorder的ZoomControl，但是我想要MouseDown的图像事件.当启用Zoomcontrol并可以正常工作时，我可以禁用子图像事件.这是我的代码.

Hello I made custom made parent control for zooming Picture . Inside That Control there is child canvas and inside Canvas There is child image Control . And I created A menu for Zoom and Image measuring . I also can able to measure co Ordinates the image . My problem when I disabled Parent ZoomBorder control I cannot triggering event of Child Image . I can disable ZoomControl named ZoomBorder but I want image event of MouseDown . I can Disable child Image event when Zoomcontrol enabled and It works. Here is my code .

<utils:ZoomBorder x:Name="ZoomBorder"   IsEnabled="{Binding IsEnableZoom}"   ClipToBounds="True" Background="Gray" Grid.Row="3" Grid.Column="2" Grid.ColumnSpan="4">
        <Canvas IsEnabled="{Binding IsEnableCanvas}">
            <Image  x:Name="DIIMGFINAL" cal:Message.Attach="[Event MouseDown] = [Action MDownCalCulateDistance($source, $eventArgs)];
                [Event MouseUp] = [Action MUpCalCulateDistance($source, $eventArgs)];
                [Event MouseMove] = [Action MMoveCalCulateDistance($source, $eventArgs)]"/>
            <Line IsHitTestVisible="False"  X1="{Binding FirstPoint.X}" Y1="{Binding FirstPoint.Y}"
                  X2="{Binding SecondPoint.X}" Y2="{Binding SecondPoint.Y}"
                  Stroke="Red" StrokeThickness="3"/>
        </Canvas>
    </utils:ZoomBorder>

这是菜单项ImageMeasuring和Zoom

And Here is The Menu Item ImageMeasuring and Zoom

<Menu Grid.ColumnSpan="3" Grid.Column="1" Grid.Row="0"  Background="Transparent" >
        <MenuItem x:Name="ズームControl" Header="ズーム">
            <!--Item For Zoom-->
        </MenuItem>

        <MenuItem x:Name="Img_Measurement" Header="Image Measurement">
            <!--Item For Measure-->
        </MenuItem>
    </Menu>

这是我的C#代码以进行缩放激活

Here is My C# code For Zoom Activation

  public void ズームControl()
    {
        //For Only Zoom
        IsEnableZoom = true;
        IsEnableCanvas = false;
        MessageBox.Show("Zoom Control Starts", "Alert", MessageBoxButton.OK, MessageBoxImage.Exclamation);
    }

这里是图像测量

 public void Img_Measurement()
    {
        IsEnableZoom = false;
        IsEnableCanvas = true;
        MessageBox.Show("Image Measurement Starts", "Alert", MessageBoxButton.OK, MessageBoxImage.Exclamation);
    }

这是我的图像MouseDown事件

Here Is My Image MouseDown Event

public void MDownCalCulateDistance(object sender, System.Windows.Input.MouseEventArgs e)
    {
         f (IsEnableCanvas == false) return;

        if (!(sender is System.Windows.Controls.Image)) return;
        try{
            //Code Here
        }
        Catch(Exception ex){
            //code here
        }
    }

这是要启用的属性

 public bool IsEnableZoom
    {
        get
        {
            return _isEnableZoom;
        }
        set
        {

            _isEnableZoom = value;
            NotifyOfPropertyChange(() => IsEnableZoom);
        }
    }

    public bool IsEnableCanvas
    {
        get
        {
            return _isEnableCanvas;
        }
        set
        {

            _isEnableCanvas = value;
            NotifyOfPropertyChange(() => IsEnableCanvas);
        }
    }

如您所见，当我关闭ZoomControl的ZoomBorder时，我无法进行MouseDown事件.当启用Parent事件的ZoomBorder时，我可以使Mousedown消失.请帮我 .预先感谢

As You can See When I disbled the ZoomBorder of ZoomControl I cannot go The MouseDown Event . I can Mousedown disbled when ZoomBorder of Parent event enabled . Please Help me . Thanks in advance
