<telerik:RadDiagram x:Name="diagram1" GraphSource="{Binding GraphSource, Mode=TwoWay}"
ShapeTemplate="{StaticResource ShapeTemplate}" SelectionMode="Extended" />
控件样式绑定资源文件（核心关键词StaticResource），所以不能重复Graph，当我重新绑定数据时，只能获取到数据，但是控件样式不发生变化
解决方案：
删除之前的控件，重新new一个，然后从资源文件中获取 模板列赋值
gdDiagram.Children.Clear();
// 新建一个RadDiagram替换之前的
Telerik.Windows.Controls.RadDiagram diagram = new Telerik.Windows.Controls.RadDiagram();
diagram.SelectionMode = (Telerik.Windows.Diagrams.Core.SelectionMode)SelectionMode.Extended;
diagram.GraphSource = viewModel.GraphSource;
diagram.ShapeTemplate = this.Resources["ShapeTemplate"] as DataTemplate;
gdDiagram.Children.Add(diagram);
