绑定DataGridTextColumn标头不起作用

标签： c# wpf data-binding

我正在尝试将文本绑定到其他语言的窗口。 但是绑定到数据网格标题不起作用 （不起作用意味着什么也不显示，就像一个空字符串）...

我有很多代码，所以我提供了重要的部分...告诉我是否错过任何信息

此绑定对我的按钮文字起作用

<Button  MinWidth="75"  MinHeight="75" MaxHeight="100" Margin="10" FontSize="25" Content="{Binding PreTestInformationProjectAccessNames.PreTestInformationProjectAccessHighText}"></Button>

我还尝试使用这种方式绑定到标头，但没有成功

  <DataGridTextColumn x:Name="Teur_ProjectColumn" Binding="{Binding Teur_Project}">
                            <DataGridTextColumn.Header>
                                <TextBlock Text="{Binding PreTestInformationProjectAccessNames.PreTestInformationProjectAccessHighText}"/>
                            </DataGridTextColumn.Header>
                        </DataGridTextColumn>

Windows：

<Window x:Class="PulserTesterMultipleHeads.UserControls.PreTestInformationProjectAccess"
            xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

                        DockPanel.Dock="Bottom" MaxHeight="300" MinHeight="300">

    </StackPanel>
        </Grid>
    </Window>

我后面的代码：

namespace PulserTesterMultipleHeads.UserControls
{
    /// <summary>
    /// Interaction logic for PreTestInformationProjectAccess.xaml
    /// </summary>
    public partial class PreTestInformationProjectAccess : Window
    {
        public PreTestInformationProjectAccess()
        {
            InitializeComponent();
            DataContext = new PreTestInformationProjectAccessVM();
            if (((PreTestInformationProjectAccessVM)DataContext).CloseAction == null)
                ((PreTestInformationProjectAccessVM)DataContext).CloseAction = new Action(this.Close);
        }
    }
}

我在ModelView中的相关部分（如果错过任何相关信息，请告诉我）

视图模型不是标头DataContext中的默认TextBlock，但是您可以使用{RelativeSource}绑定到视图模型：

<DataGridTextColumn x:Name="Teur_ProjectColumn" Binding="{Binding Teur_Project}">
    <DataGridTextColumn.Header>
        <TextBlock Text="{Binding DataContext.PreTestInformationProjectAccessNames.PreTestInformationProjectAccessHighText,
                            RelativeSource={RelativeSource AncestorType=Window}}"/>
    </DataGridTextColumn.Header>
</DataGridTextColumn>
