我有这样的DataGrid:
<DataGrid AutoGenerateColumns="False" IsReadOnly="True" SelectionMode="Single" GridLinesVisibility="None">
<DataGrid.Columns>
<DataGridTemplateColumn>
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<Border BorderThickness="{Binding ???}" BorderBrush="Black" >
<Grid></Grid>
</Border>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
</DataGrid>
我需要将CellTemplate中Border的BorderThickness绑定到DataGrid.SelectedItem。例如:如果单元格处于选定行,则厚度必须为1,1,1,1否则为零。 (我知道转换器)。怎么做?

可以使用触发器实现:
<DataGrid AutoGenerateColumns="False" IsReadOnly="True" SelectionMode="Single" GridLinesVisibility="None">
<DataGrid.Columns>
<DataGridTemplateColumn>
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<Border BorderBrush="Black" >
<Border.Style>
<Style TargetType="Border">
<Style.Triggers>
<DataTrigger Binding="{Binding IsSelected, RelativeSource={RelativeSource FindAncestor, AncestorType=DataGridCell}}" Value="True">
<Setter Property="BorderThickness" Value="1"></Setter>
</DataTrigger>
</Style.Triggers>
</Style>
</Border.Style>
<Grid></Grid>
</Border>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
</DataGrid.Columns>
</DataGrid>
或强>
直接设置CellStyle,如
<DataGrid AutoGenerateColumns="False" IsReadOnly="True" SelectionMode="Single" GridLinesVisibility="None">
<DataGrid.Columns>
<DataGridTemplateColumn>
<DataGridTemplateColumn.CellStyle>
<Style TargetType="DataGridCell">
<Style.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="BorderThickness" Value="1"></Setter>
<Setter Property="BorderBrush" Value="Black"></Setter>
</Trigger>
</Style.Triggers>
</Style>

转换器可能不是这样的方法,尝试在所选网格项上使用更改边框样式的数据触发器,在此http://www.wpf-tutorial.com/styles/trigger-datatrigger-event-trigger/
