XML代码

 <sdk:DataGrid   AutoGenerateColumns="False" Height="144"  Name="dataGrid1" VerticalAlignment="Top" Margin="12,171,153,0" CurrentCellChanged="dataGrid1_CurrentCellChanged">
                        <sdk:DataGrid.Columns>
                            <sdk:DataGridTemplateColumn>
                                <sdk:DataGridTemplateColumn.CellTemplate>
                                    <DataTemplate>
                                        <CheckBox  x:Name="myCheckbox" Checked="myCheckbox_Checked" Unchecked="myCheckbox_Unchecked" />
                                    </DataTemplate>
                                </sdk:DataGridTemplateColumn.CellTemplate>
                            </sdk:DataGridTemplateColumn>
                            <sdk:DataGridTextColumn Header="传感器" Binding="{Binding number}" FontFamily="Arial" />

                        </sdk:DataGrid.Columns>
                    </sdk:DataGrid>

后台CS代码
我在外部定义了个变量来记录选中项，虽然能用但是在实际使用过程中有BUG。请教大家如何获取所有选中的项

  List<ServiceReference1.DropDownListDataItems> dataGridlist = new List<ServiceReference1.DropDownListDataItems>();
        private void myCheckbox_Checked(object sender, RoutedEventArgs e)
        {

            CheckBox cb = sender as CheckBox;
            if (dataGrid1.SelectedItem != null)
            {
                ServiceReference1.DropDownListDataItems dr = dataGrid1.SelectedItem as ServiceReference1.DropDownListDataItems;
                dataGridlist.Add(dr);
                //MessageBox.Show("+");



            }
        }

        private void myCheckbox_Unchecked(object sender, RoutedEventArgs e)
        {
            CheckBox cb = sender as CheckBox;
            if (dataGrid1.SelectedItem != null)
            {
                ServiceReference1.DropDownListDataItems dr = dataGrid1.SelectedItem as ServiceReference1.DropDownListDataItems;
                dataGridlist.Remove(dr);
                //MessageBox.Show("-");

            }
        }

 <CheckBox x:Name="ck" Tag="{Binding CID}" ></CheckBox>

<CheckBox x:Name="CBAll" Content="全选/反选" Grid.Column="0" HorizontalContentAlignment="Center"   Height="23" Click="CheckBox_Click" Margin="4,5,0,0"></CheckBox>

 <Button Content="删除选中项"  Width="60" Height="23" Click="Button_Click"  ></Button>

 private void CheckBox_Click(object sender, RoutedEventArgs e)
        {
            if (grid.ItemsSource != null)
            {
                if (this.CBAll.IsChecked.Value)//全选
                {
                    foreach (object ovj in grid.ItemsSource)
                    {
                        CheckBox cb1 = grid.Columns[0].GetCellContent(ovj).FindName("ck") as CheckBox; //cb为

                        cb1.IsChecked = true;
                    }
                }
                else//取消
                {
                    foreach (object obj in grid.ItemsSource)
                    {
                        CheckBox cb2 = grid.Columns[0].GetCellContent(obj).FindName("ck") as CheckBox;

                        cb2.IsChecked = false;
                    }
                }
            }
        }


  private void Button_Click(object sender, RoutedEventArgs e)
        {
  
            string strID = "";
            foreach (object ovj in grid.ItemsSource)
            {
                CheckBox cb1 = grid.Columns[0].GetCellContent(ovj).FindName("ck") as CheckBox;

                if (cb1.IsChecked.Value)
                {
                    strID = strID + cb1.Tag + ",";
                }
            }
           ｝

我是这样写的 已经实现了
