WPF中网格的某些单元格的边框 [英] Border for some cells of a grid in WPF

问题描述

我有一个数据网格. 我想创建多个边框-不是针对整个网格，而是针对某些单元格.

I have a data grid. I want to create several borders - not for the entire grid, but for some of the cells.

例如:

1. 第2列第2和第3行
2. 第4列第3行和第4行.

附加我的XAML代码.

推荐答案

在Grid内添加具有正确Grid.Column，Grid.Row和Grid.RowSpan属性的Border:

add Border inside Grid with correct Grid.Column, Grid.Row and Grid.RowSpan attributes:

<Grid Grid.Column="1">
    <!--row definitions, columns definitions, controls-->

    <Border BorderThickness="1" BorderBrush="Green" 
            Grid.Column="2" Grid.Row="2" Grid.RowSpan="2"/>
    <Border BorderThickness="1" BorderBrush="Green" 
            Grid.Column="4" Grid.Row="3" Grid.RowSpan="2"/>
</Grid>
