dataGrid 上的 SharedSizeGroup

Question

我的 WPF 应用程序上有一个 DataGrid 和一个网格，我希望它们所尊重的列具有相同的大小。我想也许我使用 SharedSizeGroup 但似乎 DataGrid 列没有此属性（我错了吗？）。 我该怎么做？

Update1

我更改了 xaml，如下所示：

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="20" MaxHeight="20" MinHeight="20" />
        <RowDefinition />
    </Grid.RowDefinitions>
    <Grid >
        <Grid.ColumnDefinitions >
            <ColumnDefinition   Width="{Binding ElementName=titleDataGridColumn, Path=ActualWidth}" />
            <ColumnDefinition   Width="{Binding ElementName=forenameDataGridColumn, Path=ActualWidth}"/>
            <ColumnDefinition   Width="{Binding ElementName=surnameDataGridColumn, Path=ActualWidth}" />
            <ColumnDefinition   Width="{Binding ElementName=dobDataGridColumn, Path=ActualWidth}" />
            </Grid.ColumnDefinitions>
        <Button Content="Clear" HorizontalAlignment="Stretch" Name="searchClearButton" VerticalAlignment="Stretch"   Grid.Column="0" Click="searchClearButton_Click" />
        <TextBox HorizontalAlignment="Stretch"  Name="forenameTextBox" VerticalAlignment="Stretch" Grid.Column="1" />
        <TextBox HorizontalAlignment="Stretch"  Name="surnameTextBox" VerticalAlignment="Stretch" Grid.Column="2" />
        <TextBox HorizontalAlignment="Stretch"  Name="dobTextBox" VerticalAlignment="Stretch" Grid.Column="3" />

    </Grid>

    <DataGrid Grid.Row="1" x:Name="DataDataGrid" HorizontalAlignment="Stretch" AutoGenerateColumns="False" VerticalAlignment="Stretch"  ItemsSource="{Binding}" AlternationCount="1"  IsReadOnly="True" SelectionMode="Single" >
        <DataGrid.Columns>
            <DataGridTextColumn x:Name="titleDataGridColumn" Binding="{Binding Path='Title'}" Header="Title" Width="35*"    />
            <DataGridTextColumn x:Name="forenameDataGridColumn" Binding="{Binding Path='Forename'}" Header="Forename" Width="65*" />
            <DataGridTextColumn x:Name="surenameDataGridColumn" Binding="{Binding Path='Surname'}" Header="Surname" Width="65*"/>
            <DataGridTextColumn x:Name="dobDataGridColumn" Binding="{Binding DOB,StringFormat={}\{0:dd/MM/yyyy\}}"  Header="DOB" Width="70*"/>
        </DataGrid.Columns>
    </DataGrid>

</Grid>

但现在网格中的姓氏列比数据网格中的相应列大，并且按钮有点偏左（可以通过在网格列上设置边距来修复），但我无法理解为什么姓氏列是尺寸不一样？

这是工作（问题是surenameDataGridColumn 不正确（拼写））

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="20" MaxHeight="20" MinHeight="20" />
        <RowDefinition />
    </Grid.RowDefinitions>
    <Grid >
        <Grid.ColumnDefinitions >
            <ColumnDefinition Width="6px"/>
            <ColumnDefinition   Width="{Binding ElementName=titleDataGridColumn, Path=ActualWidth}" />
            <ColumnDefinition   Width="{Binding ElementName=forenameDataGridColumn, Path=ActualWidth}"/>
            <ColumnDefinition   Width="{Binding ElementName=surnameDataGridColumn, Path=ActualWidth}" />
            <ColumnDefinition   Width="{Binding ElementName=dobDataGridColumn, Path=ActualWidth}" />
        </Grid.ColumnDefinitions>
        <Button Content="Clear" HorizontalAlignment="Stretch" Name="searchClearButton" VerticalAlignment="Stretch"   Grid.Column="1" Click="searchClearButton_Click" />
        <TextBox HorizontalAlignment="Stretch"  Name="forenameTextBox" VerticalAlignment="Stretch" Grid.Column="2" />
        <TextBox HorizontalAlignment="Stretch"  Name="surnameTextBox" VerticalAlignment="Stretch" Grid.Column="3" />
        <TextBox HorizontalAlignment="Stretch"  Name="dobTextBox" VerticalAlignment="Stretch" Grid.Column="4" />
       </Grid>

    <DataGrid Grid.Row="1" x:Name="DataGrid" HorizontalAlignment="Stretch" AutoGenerateColumns="False" VerticalAlignment="Stretch"  ItemsSource="{Binding}" AlternationCount="1"  IsReadOnly="True" >
        <DataGrid.Columns>
            <DataGridTextColumn x:Name="titleDataGridColumn" Binding="{Binding Path='Title'}" Header="Title" Width="35*"    />
            <DataGridTextColumn x:Name="forenameDataGridColumn" Binding="{Binding Path='Forename'}" Header="Forename" Width="65*" />
            <DataGridTextColumn x:Name="surnameDataGridColumn" Binding="{Binding Path='Surname'}" Header="Surname" Width="65*"/>
            <DataGridTextColumn x:Name="dobDataGridColumn" Binding="{Binding DOB,StringFormat={}\{0:dd/MM/yyyy\}}"  Header="DOB" Width="70*"/>
       </DataGrid.Columns>
    </DataGrid>
</Grid>

通过添加新列，我将按钮的左侧与DataGrid 中标题列的左侧对齐。

使用绑定将 Grid 列宽绑定到 DataGrid 中的列大小。例如：

<dg:DataGridTextColumn x:Name="FirstColumn" Header="Text"/>

<ColumnDefinition Width="{Binding ElementName=FirstColumn, Path=ActualWidth}"/>
