Silverlight 3.0图表中的自定义光标

当我看到解决方案时，我可能忽略了一些显而易见的事情，但现在

        <dataVisTK:Title Content="{TemplateBinding Title}"
                         Style="{TemplateBinding TitleStyle}"/>

        <Grid Grid.Row="1">

            <!-- Remove the Legend -->
            <!--<dataVisTK:Legend
        x:Name="Legend"
        Title="{TemplateBinding LegendTitle}"
        Style="{TemplateBinding LegendStyle}"
        Grid.Column="1"/>-->


            <chartingPrimitivesTK:EdgePanel x:Name="ChartArea" 
                                            Background="#EDAEAE"
                                            Style="{TemplateBinding ChartAreaStyle}"
                                            Grid.Column="0">
                <Grid Canvas.ZIndex="-1" 
                      Background="#2008AE"
                      Style="{TemplateBinding PlotAreaStyle}">
                </Grid>
                <Border Canvas.ZIndex="1" 
                        BorderBrush="#FF250010" 
                        BorderThickness="3" />

                <Grid x:Name="gridHandCursors" 
                      Canvas.ZIndex="5"
                      Width="32" Height="32"

                    <Image x:Name="cursorGrabbing" Width="32"

                           Visibility="Collapsed"/>
                </Grid>

            </chartingPrimitivesTK:EdgePanel>
        </Grid>

我试图在工具箱图表的图表区域内使用自定义光标。我为图表创建了一个ControlTemplate，并创建了一个包含光标的网格。我使用各种鼠标事件显示/隐藏光标，并尝试移动包含的网格。光标在正确的时间显示，但我无法将其移动到正确的位置

        <dataVisTK:Title Content="{TemplateBinding Title}"
                         Style="{TemplateBinding TitleStyle}"/>

        <Grid Grid.Row="1">

            <!-- Remove the Legend -->
            <!--<dataVisTK:Legend
        x:Name="Legend"
        Title="{TemplateBinding LegendTitle}"
        Style="{TemplateBinding LegendStyle}"
        Grid.Column="1"/>-->


            <chartingPrimitivesTK:EdgePanel x:Name="ChartArea" 
                                            Background="#EDAEAE"
                                            Style="{TemplateBinding ChartAreaStyle}"
                                            Grid.Column="0">
                <Grid Canvas.ZIndex="-1" 
                      Background="#2008AE"
                      Style="{TemplateBinding PlotAreaStyle}">
                </Grid>
                <Border Canvas.ZIndex="1" 
                        BorderBrush="#FF250010" 
                        BorderThickness="3" />

                <Grid x:Name="gridHandCursors" 
                      Canvas.ZIndex="5"
                      Width="32" Height="32"
                      Visibility="Collapsed">
                    <Image x:Name="cursorGrab" Width="32"
                           Source="Resources/grab.png" />
                    <Image x:Name="cursorGrabbing" Width="32"
                           Source="Resources/grabbing.png"
                           Visibility="Collapsed"/>
                </Grid>

            </chartingPrimitivesTK:EdgePanel>
        </Grid>                            
    </Grid>
</Border>

这是ControlTemplate（时髦的颜色只是试图确认模板的不同部分与什么有关）：

        <dataVisTK:Title Content="{TemplateBinding Title}"
                         Style="{TemplateBinding TitleStyle}"/>

        <Grid Grid.Row="1">

            <!-- Remove the Legend -->
            <!--<dataVisTK:Legend
        x:Name="Legend"
        Title="{TemplateBinding LegendTitle}"
        Style="{TemplateBinding LegendStyle}"
        Grid.Column="1"/>-->


            <chartingPrimitivesTK:EdgePanel x:Name="ChartArea"

                                            Style="{TemplateBinding ChartAreaStyle}"
                                            Grid.Column="0">
