动态检索画布中元素的x，y位置

Question

我有这段代码

        <Canvas x:Name="SampleCanvas" Background="#F5F7F9"  MouseLeftButtonDown="brdMovable_MouseLeftButtonDown" MouseLeftButtonUp="brdMovable_MouseLeftButtonUp" MouseMove="brdMovable_MouseMove" Height="570" Width="875">                    
         <chartingToolkit:Chart  x:Name="mcChart" Loaded="mcChart_Loaded"  Width="400" Height="250" Canvas.Left="190" Canvas.Top="5" MouseLeftButtonDown="brdMovable_MouseLeftButtonDown"
                             Background="LightSteelBlue">
                        <chartingToolkit:Chart.RenderTransform>
                            <ScaleTransform x:Name="scaleTransform"></ScaleTransform>
                        </chartingToolkit:Chart.RenderTransform>
                        <chartingToolkit:Chart.Series>
                            <chartingToolkit:ColumnSeries Title="Experience"  IndependentValueBinding="{Binding Path=ModelName}" DependentValueBinding="{Binding  Path=SaleCount}">
                            </chartingToolkit:ColumnSeries>
                        </chartingToolkit:Chart.Series>
                    </chartingToolkit:Chart> 
          </canvas>

现在我想在代码隐藏中动态检索canvas.Left位置和canvas.Top位置mcChart。

我该怎么做？ 感谢。

Answer 1

您需要对mcChart的引用。然后，您可以使用附加属性访问器来获取当前值：

double left = Canvas.GetLeft(mcChart);
double top  = Canvas.GetTop(mcChart);

在代码中设置值：

Canvas.SetLeft(mcChart, 50);
Canvas.SetTop(mcChart, 100);

Answer 2

怎么样：

Canvas.GetLeft(mcChart);
Canvas.GetTop(mcChart);
