如果值大于，XAML Datagrid 设置 rowStyle

发布于 2025-01-19 18:02:26 字数 1429 浏览 1 评论 0原文

我有一个带有3列的数据杂志。

现在，我想有条件地更改行的亮点。类似：如果第2列中的值大于xx将行颜色更改为红色。

我已经尝试了一些事情，但是没有成功：

<DataGrid Name="DataGrid1" Grid.Row="3" Grid.Column="1" Grid.ColumnSpan="3" AlternatingRowBackground="LightGray"  ItemsSource="{Binding}" AutoGenerateColumns="False" FontSize="18" CanUserResizeColumns="False" CanUserReorderColumns="False" CanUserSortColumns="False" CanUserAddRows="False">
        <DataGrid.RowStyle>
            <Style TargetType="DataGridRow">
                <Style.Triggers>
                    <DataTrigger Binding="{Binding Steckzyklen}" Value="&lt; 20">
                        <Setter Property="Background" Value="#FFFF4848"></Setter>
                    </DataTrigger>
                </Style.Triggers>
            </Style>
        </DataGrid.RowStyle>
        <DataGrid.Columns>
            <DataGridTextColumn Header="Steckplatz"  Binding="{Binding Name}" Width="200"/>
            <DataGridTextColumn Header="Steckzyklen"  Binding="{Binding Steckzyklen}" Width="200"/>
            <DataGridTextColumn Header="Austauschdatum"  Binding="{Binding Austauschdatum}" Width="200"/>
        </DataGrid.Columns>
    </DataGrid>

在这一行中：dataTrigger binding =“ {binding steckzyklen}” value =“＆amp; lt 20” 我尝试用＆amp; lt做这件事，但没有成功。

有人知道如何使它起作用？最好仅通过更改XAML中的内容。

提前致谢！

I've got a Datagrid with 3 columns.

Now i want to change the highlight of the row conditionally.
like: if the value in column 2 is greater than XX change row color to Red.

I've already tried something, but without success:

<DataGrid Name="DataGrid1" Grid.Row="3" Grid.Column="1" Grid.ColumnSpan="3" AlternatingRowBackground="LightGray"  ItemsSource="{Binding}" AutoGenerateColumns="False" FontSize="18" CanUserResizeColumns="False" CanUserReorderColumns="False" CanUserSortColumns="False" CanUserAddRows="False">
        <DataGrid.RowStyle>
            <Style TargetType="DataGridRow">
                <Style.Triggers>
                    <DataTrigger Binding="{Binding Steckzyklen}" Value="< 20">
                        <Setter Property="Background" Value="#FFFF4848"></Setter>
                    </DataTrigger>
                </Style.Triggers>
            </Style>
        </DataGrid.RowStyle>
        <DataGrid.Columns>
            <DataGridTextColumn Header="Steckplatz"  Binding="{Binding Name}" Width="200"/>
            <DataGridTextColumn Header="Steckzyklen"  Binding="{Binding Steckzyklen}" Width="200"/>
            <DataGridTextColumn Header="Austauschdatum"  Binding="{Binding Austauschdatum}" Width="200"/>
        </DataGrid.Columns>
    </DataGrid>

In this line: DataTrigger Binding="{Binding Steckzyklen}" Value="< 20"
I tried ti do it with the < but without succes.

Someone knows how to make it work? Preferably by only changing something in the XAML.

Thanks in advance!

您可以按以下方式更改样式：

创建一个新的转换器：

    public class IsEqualOrLessThanConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            int intValue = (int)value;
            int compareToValue = Int32.Parse(parameter.ToString() ?? string.Empty);

            return intValue <= compareToValue;
        }

        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
        {
            throw new NotImplementedException();
        }
    }

然后：

<Style TargetType="DataGridRow">
    <Style.Triggers>
        <DataTrigger Binding="{Binding Steckzyklen, Converter={StaticResource IsEqualOrLessThanConverter}, ConverterParameter=20}" Value="True">    
            <Setter Property="Foreground" Value="#FFFF4848"/>
            <Setter Property="Background" Value="Yellow"/>
        </DataTrigger>
    </Style.Triggers>
</Style>

You can change the Style as follows:

Create a new Converter:

    public class IsEqualOrLessThanConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            int intValue = (int)value;
            int compareToValue = Int32.Parse(parameter.ToString() ?? string.Empty);

            return intValue <= compareToValue;
        }

        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
        {
            throw new NotImplementedException();
        }
    }

And then:

<Style TargetType="DataGridRow">
    <Style.Triggers>
        <DataTrigger Binding="{Binding Steckzyklen, Converter={StaticResource IsEqualOrLessThanConverter}, ConverterParameter=20}" Value="True">    
            <Setter Property="Foreground" Value="#FFFF4848"/>
            <Setter Property="Background" Value="Yellow"/>
        </DataTrigger>
    </Style.Triggers>
</Style>
