WPF中DataGrid解析

效果如图：

代码如下：

<DataGrid Grid.Row="1" x:Name="dataGrid" ItemsSource="{Binding DataList}" AutoGenerateColumns="False"
   SelectedItem="{Binding SelectedItem,UpdateSourceTrigger=PropertyChanged}" IsReadOnly="True"
   ColumnHeaderStyle="{StaticResource UnitColumnHeader}" RowHeaderWidth="0" 
   ScrollViewer.HorizontalScrollBarVisibility="Hidden" >
    <DataGrid.Columns>
        <DataGridTextColumn Width="1.5*"  Header="CoilId"  Binding="{Binding COIL_ID}"  ElementStyle="{StaticResource MyDataGridCellStyle}"/>
        <DataGridTextColumn Width="1.2*"  Header="AlloyId" Binding="{Binding ALLOY_ID}"  ElementStyle="{StaticResource MyDataGridCellStyle}"/>
        <DataGridTextColumn Width="1*"    Header="Entry Thickness&#x0a;[mm]" Binding="{Binding ENTRY_THICKNESS}"  ElementStyle="{StaticResource MyDataGridCellStyle}"/>
        <DataGridTextColumn Width="1*"    Header="Exit Thickness&#x0a;[mm]" Binding="{Binding EXIT_THICKNESS}"  ElementStyle="{StaticResource MyDataGridCellStyle}"/>
        <DataGridTextColumn Width="1*"    Header="Exit Diam&#x0a;[mm]" Binding="{Binding COIL_DIAM}"  ElementStyle="{StaticResource MyDataGridCellStyle}"/>
        <DataGridTextColumn Width="1*"    Header="Exit Length&#x0a;[mm]" Binding="{Binding COIL_LENGTH}"  ElementStyle="{StaticResource MyDataGridCellStyle}"/>
        <DataGridTextColumn Width="1.2*"  Header="StartTime" Binding="{Binding START_TIME}"  ElementStyle="{StaticResource MyDataGridCellStyle}"/>
        <DataGridTextColumn Width="1.2*"  Header="EndTime" Binding="{Binding STOP_TIME}"  ElementStyle="{StaticResource MyDataGridCellStyle}"/>
        <DataGridTextColumn Width="1.2*"  Header="TotalTime" Binding="{Binding DURATIONTIME}"  ElementStyle="{StaticResource MyDataGridCellStyle}"/>
        <DataGridTemplateColumn Width="1.2*"  Header="PDF" >
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <Button Content="{Binding COIL_ID}" Width="196"  Style="{StaticResource BasicButtonStyle}"  Command="{Binding DataContext.MakePDFReport,RelativeSource={RelativeSource AncestorType={x:Type DataGrid}}}" />
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
        </DataGridTemplateColumn>
    </DataGrid.Columns>
</DataGrid>

1、给单个的列设置新的组件：在DataTemplate里设置

2、点击按钮 获取到相应数据

在DataGrid的属性SelectedItem绑定单个数据源

3、DataGrid里的事件绑定特殊：
