wpf - DrawingBrush 将 WPF DataGrid 单元格作为背景

Question

我想设置一个DrawingBrush并DataGridCell使用

<DrawingBrush TileMode="Tile" ViewportUnits="RelativeToBoundingBox" Viewport="0,0,0.05,1">
     <DrawingBrush.Drawing>
         <DrawingGroup>
              <GeometryDrawing>
                   <GeometryDrawing.Pen>
                         <Pen Brush="Gray" Thickness="0.05"/>
                    </GeometryDrawing.Pen>
                    <GeometryDrawing.Geometry>
                          <LineGeometry StartPoint="0,1" EndPoint="1,0" />
                    </GeometryDrawing.Geometry>
              </GeometryDrawing>
          </DrawingGroup>
     </DrawingBrush.Drawing>
</DrawingBrush>

DataGridCells当宽度不相等时，我会得到不想要的结果，如下所示。

我应该如何更改画笔，以便无论单个单元格的宽度如何，结果都会像这样。

Answer 1

从到调整。ViewportUnits_RelativeToBoundingBoxAbsoluteViewport

坐标系与边界框无关。值直接在本地空间中解释。

像这样的东西：

<DrawingBrush 
    x:Key="DrawingBrush" 
    TileMode="Tile" 
    ViewportUnits="Absolute" 
    Viewport="0,0,5,15">

看起来像这样
