Question

我想在WPF DataGrid中为多个列执行标头操作。我尝试使用Header模板但它会显示一列的Header。

在XAML下面，我尝试过：

  <DataGrid>
        <DataGrid.Columns>
            <DataGridTextColumn>
                <DataGridTextColumn.HeaderTemplate>
                    <DataTemplate>
                        <StackPanel>
                            <TextBlock>Column 1</TextBlock>
                            <TextBlock>xyz</TextBlock>
                        </StackPanel>
                    </DataTemplate>
                </DataGridTextColumn.HeaderTemplate>
            </DataGridTextColumn>
            <DataGridTextColumn Header="Header" />
        </DataGrid.Columns>
    </DataGrid>

我还附上了我的预期结果屏幕截图：

 <Grid Width="Auto">
                    <Grid.RowDefinitions>
                        <RowDefinition />
                        <RowDefinition />
                    </Grid.RowDefinitions>
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition />
                        <ColumnDefinition />
                        <ColumnDefinition />
                    </Grid.ColumnDefinitions>
                    <toolkit:DataGrid x:Name="problemsList"

                    </toolkit:DataGrid>
                    <CmcControls:WaitingControl x:Name="waitingControlOnGrid"

试试这个; - ＆gt;

如果您想要ScreenShot描绘的方式，您只需要使用2行和3列。在第一行中，使用Grid.ColumnsSpan =“3”定义TextBlock，这将占用3列的空间，而在第二行定义每个不同列中的每个TextBlock：

     <DataGrid ItemsSource="{Binding  FisapCorrections,RelativeSource={RelativeSource AncestorType=Window},UpdateSourceTrigger=PropertyChanged,Mode=TwoWay}">
        <DataGrid.Columns>
        <DataGridTemplateColumn Width="200">
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <Grid>
                        <Grid.RowDefinitions>
                            <RowDefinition Height="150"/>
                            <RowDefinition Height="150"/>
                        </Grid.RowDefinitions>
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width="70" />
