Wpf 散点视图项自定义形状
我有一个ScatterViewItem，其中包含一个画布Wpf 散点视图项自定义形状,wpf,pixelsense,scatterview,Wpf,Pixelsense,Scatterview,我有一个ScatterViewItem，其中包含一个画布 <Ellipse x:Name="Outer_Ellipse" Fill="White" Width="200" Height="200"></Ellipse> <Ellipse Fill="Red" Canvas.Top ="15" Canvas.Left="15" Canvas.Right="15" Canvas.Bottom="15" Wi

将覆盖ScatterViewItem的内容，即在我的示例中是画布，或者在另一个示例中是图像。目前，我不需要移动或缩放散射视图项，因此不需要阴影，我只想删除矩形框。您可以通过修改散射视图项的

请注意，如果使用Expression Blend，则可能需要添加对Microsoft.Surface.Presentation.Generic.dll的引用才能执行此操作，否则Blend可能会在编辑模板时崩溃。您可以通过修改ScatterViewItem的
