                                                              Tag="{Binding ID}" 
                                                              Height="20" Width="50"
                                                              />
                                         </DataTemplate>
                                     </telerik:GridViewColumn.CellTemplate>
                                 </telerik:GridViewColumn>
                             </telerik:RadGridView.Columns>
                         </telerik:RadGridView>

在GridViewColumn中添加GridViewColumn.CellTemplate，并在其子节点添加DataTemplate，在其中添加你想要的控件。可以在不同的控件中设置数据源绑定。

我在给RadGridView赋值的时候是通过赋值LIST集合赋值。

例如，this.activitiesGrid.ItemsSource = e.Result.ToList();---此处指的是从服务引用中返回的数据源（大家都懂得）

若你想你的控件在展示的时候默认显示第一行，请添加如下代码：

 if (this.activitiesGrid.Items.Count>0)
 {
 this.activitiesGrid.SelectedItem = activitiesGrid.Items[0];
 }   

在后台控制控件中某一列的显示和隐藏
声明GridViewColumn 对象，取得对象之后控制显示和隐藏

GridViewColumn column = this.activitiesGrid.Columns[第几行];

column.IsVisible = true;//显示这一列

在后台取得某一行的数据源

（在这里我用了一个技巧，在给RadGridView绑定数据源的同时，我给每一个行的数据源绑定了一个ID，是为了取得每一个行的数据源）

在RadGridView控件中，每一行我定义一个控件，例如是RadButton控件，在他的Tag属性中我绑定了这一行数据源的ID，点击事件后我将这行的ID取出，然后可以得到其数据源，前后台代码如下：

前台代码：

View Code
 <telerik:GridViewColumn Header="删除" Width="*"     HeaderCellStyle="{StaticResource SalesInfoGridViewHeaderCellStyleFirst}"
                                                         CellStyle="{StaticResource SalesInfoGridViewCellStyle}">
                                 <telerik:GridViewColumn.CellTemplate>
                                     <DataTemplate>
                                         <telerik:RadButton   Style="{StaticResource RadButtonStyle}" Content="删除"
                                                              FontSize="12" Foreground="White" 
                                                              Tag="{Binding ID}" 
                                                              Height="20" Width="50"
                                                              Click="RadButton_Click_2" />
                                     </DataTemplate>
                                 </telerik:GridViewColumn.CellTemplate>
                             </telerik:GridViewColumn>

后台代码：

View Code 
  private void btDeny_Click(object sender, RoutedEventArgs e)
         {
             RadButton btn = sender as RadButton;
             int num = Convert.ToInt32(btn.TabIndex.ToString());
             GridViewRow row=new GridViewRow();
             var item = this.BackUserDetailes.Items[num];//绑定数据源的同时，给从库中返回的数据源制定了ID
              row=this.BackUserDetailes.ItemContainerGenerator.ContainerFromItem(item) as GridViewRow;
 //得到Row对象后可以将其的数据源转换成你想要的类型
 想要的类型=row.DataContext as 想要的类型;
          }

也可以用另外一种简单的方式获得这一行的数据源
想要的类型=btn.DataContext as 想要的类型。

 在后台获取行中有不同控件值的方法

取得了GridViewRow对象之后，可以取得这一行的每个单元格，即可把单元格中的控件取出。代码如下：

例如，你在这一单元格中放置的是RadComboBox控件，可以通过：RadComboBox box=row.Cells[第几个单元格].Content as RadComboBox;将RadComboBox对象取出，并进行你想要的操作。

在RadGridView中对某一列的特殊的控件赋值，通过这一列的控件中声明其Loaded事件，为这一行的特殊的控件赋值。

例如下例：

View Code
  <telerik:GridViewColumn Header="给特殊列绑定单个数据" Width="*"     HeaderCellStyle="{StaticResource SalesInfoGridViewHeaderCellStyleFirst}"
                                                         CellStyle="{StaticResource SalesInfoGridViewCellStyle}" >
                                 <telerik:GridViewColumn.CellTemplate>
                                     <DataTemplate>
                                         <telerik:RadComboBox EmptyText="{Binding 绑定的数据源中字段名称}"  Text="{Binding 绑定的数据源中字段名称}"
                                                              FontSize="14" Width="200" HorizontalAlignment="Left"
                                                              Style="{StaticResource RadComboBoxStyle1}"   
                                                              Loaded="RadComboBox_Loaded">
                                             <telerik:RadComboBoxItem Content="{Binding 绑定的数据源中字段名称}" Tag="{Binding CHNL_ID}" Style="{StaticResource RadComboBoxItemStyle1}" />
                                         </telerik:RadComboBox>
                                     </DataTemplate>
                                 </telerik:GridViewColumn.CellTemplate>
                             </telerik:GridViewColumn>

其中，EmptyText="{Binding 绑定的数据源的名称}"指的是其RadComboBox在没有 默认显示第一个值时的赋予该控件的值。
后台代码如下：

View Code
  private void RadComboBox_Loaded(object sender, RoutedEventArgs e)
         {
             RadComboBox box = sender as RadComboBox;
             box.Items.Clear();
             (sender as RadComboBox).DisplayMemberPath = "ROOM_NAME";
             (sender as RadComboBox).Tag = this.chnlList[0].ROOM_ID;
             (sender as RadComboBox).ItemsSource = 数据源名称;          
             box.ItemsSource = chnlList;
         }
