如何动态的为“DataGrid”添加“列”？？？
如何动态的为“DataGrid”添加“列”？？？ 也就是通过后台代码添加列。。。“DataGrid”定义如下：
<sdk:DataGrid Grid.Row="1" Name="dg_EnergyCustom" AutoGenerateColumns="False" >
<sdk:DataGrid.Columns>
<sdk:DataGridTemplateColumn DisplayIndex="-1" Header="年份" IsReadOnly="True" Width="30*" >
<sdk:DataGridTemplateColumn.CellTemplate >
<DataTemplate>
<TextBlock FontSize="13" HorizontalAlignment="Center" VerticalAlignment="Center" Text="{Binding EnergyYear}"></TextBlock>
</DataTemplate>
</sdk:DataGridTemplateColumn.CellTemplate>
</sdk:DataGridTemplateColumn>
<sdk:DataGridTemplateColumn Header="项目" Width="30*">
<sdk:DataGridTemplateColumn.CellTemplate >
<DataTemplate>
<Grid ShowGridLines="True" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" >
<Grid.RowDefinitions>
<RowDefinition Height="20" />
<RowDefinition Height="20"/>
<RowDefinition Height="20"/>
</Grid.RowDefinitions>
<TextBlock Text="能耗量合计" Grid.Row="0" ></TextBlock>
<TextBlock Text="单位面积能耗" Grid.Row="1"></TextBlock>
<TextBlock Text="生均能耗" Grid.Row="2"></TextBlock>
</Grid>
</DataTemplate>
</sdk:DataGridTemplateColumn.CellTemplate>
</sdk:DataGridTemplateColumn>
<sdk:DataGridTemplateColumn Header="全校" Width="40*">
<sdk:DataGridTemplateColumn.CellTemplate >
<DataTemplate>
<Grid ShowGridLines="True" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<Grid.RowDefinitions>
<RowDefinition Height="20" />
<RowDefinition Height="20"/>
<RowDefinition Height="20"/>
</Grid.RowDefinitions>
<TextBlock Grid.Row="0" Text="{Binding EnergySum}" ></TextBlock>
<TextBlock Grid.Row="1" Text="{Binding EnergyUnitArea}" ></TextBlock>
<TextBlock Grid.Row="2" Text="{Binding EnergyEveryOne}"></TextBlock>
</Grid>
</DataTemplate>
</sdk:DataGridTemplateColumn.CellTemplate>
</sdk:DataGridTemplateColumn>
</sdk:DataGrid.Columns>
</sdk:DataGrid>
问题：
如何通过后台代码为“DataGrid”添加一列？？？列的静态XAML定义如下：
<sdk:DataGridTemplateColumn Header="电信学院" Width="40*">
<sdk:DataGridTemplateColumn.CellTemplate >
<DataTemplate>
<Grid ShowGridLines="True" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<Grid.RowDefinitions>
<RowDefinition Height="20" />
<RowDefinition Height="20"/>
<RowDefinition Height="20"/>
</Grid.RowDefinitions>
<TextBlock Grid.Row="0" Text="{Binding EnergySum1}" ></TextBlock>
<TextBlock Grid.Row="1" Text="{Binding EnergyUnitArea1}" ></TextBlock>
<TextBlock Grid.Row="2" Text="{Binding EnergyEveryOne1}"></TextBlock>
</Grid>
</DataTemplate>
</sdk:DataGridTemplateColumn.CellTemplate>
</sdk:DataGridTemplateColumn>
</sdk:DataGrid.Columns>
个人思路：
实例化“DataGridTemplateColumn”对象“DataGridTemplateColumn dgtc = new DataGridTemplateColumn();”，然后将“dgtc”添加到“DataGrid”中。
但是自己不知道，“CellTemplate”、“DataTemplate”这些元素怎样实例化，然后添加进入“ DataGridTemplateColumn”对象中。这样的功能应该怎么写？？？ --------------------编程问答-------------------- 不知C#代码改怎么写？？？ --------------------编程问答-------------------- dg.Columns.Clear();
BoundColumn colList = new BoundColumn();
colList = new BoundColumn();
colList.DataField="ID";
colList.SortExpression="ID";
colList.HeaderText="序号↓";
dg.Columns.Add(colList);

易做图，我这是基于Silverlight的啊。 --------------------编程问答--------------------
补充：.NET技术 , C#
