推荐答案

您可能想做这样的事情

You probably want to do something like this

<sdk:DataGrid AutoGenerateColumns="False" Height="312" HorizontalAlignment="Left" Name="dataGrid1" VerticalAlignment="Top" Width="388" DataContext="{Binding Source={StaticResource ViewModel}}" ItemsSource="{Binding Path=Items}">
    <sdk:DataGrid.Columns>
        <sdk:DataGridTemplateColumn CanUserReorder="True" CanUserResize="True" CanUserSort="True" Width="Auto" Header="Name">
            <sdk:DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Path=Name}"/>
                </DataTemplate>
            </sdk:DataGridTemplateColumn.CellTemplate>
            <sdk:DataGridTemplateColumn.CellEditingTemplate>
                <DataTemplate>
                    <Button Content="{Binding Path=Name}"/>
                </DataTemplate>
            </sdk:DataGridTemplateColumn.CellEditingTemplate>
        </sdk:DataGridTemplateColumn>
        <sdk:DataGridTemplateColumn CanUserReorder="True" CanUserResize="True" CanUserSort="True" Width="Auto" Header="Active">
            <sdk:DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Path=Active}"/>
                </DataTemplate>
            </sdk:DataGridTemplateColumn.CellTemplate>
            <sdk:DataGridTemplateColumn.CellEditingTemplate>
                <DataTemplate>
                    <CheckBox IsChecked="{Binding Path=Active}"/>
                </DataTemplate>
            </sdk:DataGridTemplateColumn.CellEditingTemplate>
        </sdk:DataGridTemplateColumn>
        <sdk:DataGridTemplateColumn CanUserReorder="True" CanUserResize="True" CanUserSort="True" Width="Auto" Header="ID">
            <sdk:DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <ProgressBar Height="20" Maximum="10" Value="{Binding Path=ID}"/>
                </DataTemplate>
            </sdk:DataGridTemplateColumn.CellTemplate>
            <sdk:DataGridTemplateColumn.CellEditingTemplate>
                <DataTemplate>
                    <TextBox Text="{Binding Path=ID}"/>
                </DataTemplate>
            </sdk:DataGridTemplateColumn.CellEditingTemplate>
        </sdk:DataGridTemplateColumn>
    </sdk:DataGrid.Columns>
</sdk:DataGrid>

同样，也可以通过c#代码实现.让我知道您是否需要.

Same can be achieved by c# code as well. Let me know if you require that.
