Question

我遇到了一个非常愚蠢的问题 - 需要在WPF DataGrid中设置所选行的样式。

我想要显示一个带蓝色边框的矩形，而不是只用一些颜色填充整行。

任何想法如何实现？它必须是某种方式使它变得非常容易。

在CellStyle上使用RowStyle和DataGrid。 DataGridCell和DataGridRow都有IsSelected属性，可以在Trigger中使用，以确定它们是否已被选中。

像下面这样的事情可以解决问题：

<DataGrid.CellStyle>
    <Style TargetType="DataGridCell">
        <Style.Triggers>
            <Trigger Property="IsSelected"
                        Value="True">
                <Setter Property="Background"
                        Value="White" />
                <Setter Property="Foreground"
                        Value="Black" />
            </Trigger>
        </Style.Triggers>
    </Style>
</DataGrid.CellStyle>
<DataGrid.RowStyle>
    <Style TargetType="DataGridRow">
        <Style.Triggers>
            <Trigger Property="IsSelected"
                        Value="True">
                <Setter Property="BorderBrush"
                        Value="Blue" />
                <Setter Property="BorderThickness"
                        Value="2" />
            </Trigger>
        </Style.Triggers>
    </Style>
</DataGrid.RowStyle>

只要玩得开心，直到你做对了。

我喜欢这个：

emit -limit 1
|(
  put field1 = 1, field2 = 2;
  put field2 = 2, field3 = 3;
)| split // break each point into one point for each field, assigning each field name into the point's name field
 | reduce by name // get unique list of name field values
 | sort name
 | @logger

{"name":"field3"}
{"name":"field2"}
{"name":"field1"}

<DataGrid.Resources>
                    <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent"/>

                    <Style TargetType="{x:Type DataGridRow}">
