使用WPF我已矩形的列表(其可具有在其矩形未定义数量),和一画布。我要使用数据绑定定位在画布上的矩形。
Using WPF I have a list of rectangles (which can have an undefined number of rectangles in it), and a canvas. I want to position those rectangles on the canvas using data binding.
我使用的是项目控制试过了,而且似乎堆栈中的下一个像垂直堆叠面板上的每个项目。
I have tried using an items control, and seems to stack each item on top of the next one like a vertical stack panel.
所有我的矩形具有坐标0,0,但它们都是在彼此向下画布。的顶部
All my rectangles have the co-ordinates 0,0, but they are all on top of each other down the canvas.
要使用项目控制任何替代品?
Any alternatives to using an items control?
您需要的时候必然要考虑的项目包装:
You need to account for the wrapping of the items when bound:
<ItemsControl ItemsSource="{Binding Data}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<Canvas />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemContainerStyle>
<Style>
<Setter Property="Canvas.Left" Value="{Binding X}"/>
<Setter Property="Canvas.Top" Value="{Binding Y}"/>
</Style>
</ItemsControl.ItemContainerStyle>
<ItemsControl.ItemTemplate>
<DataTemplate>
<!-- Item Template -->
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
