运行界面：

前台代码：

     <Grid>
        <DataGrid AutoGenerateColumns="True" Height="211" HorizontalAlignment="Left" Margin="27,34,0,0" Name="dataGrid1" VerticalAlignment="Top" Width="334" IsReadOnly="True">
            <DataGrid.Columns>
                <DataGridTemplateColumn Header="选择">
                    <DataGridTemplateColumn.CellEditingTemplate>
                        <DataTemplate />
                    </DataGridTemplateColumn.CellEditingTemplate>
                    <DataGridTemplateColumn.CellTemplate>
                        <DataTemplate >
                            <CheckBox Tag="{Binding Path=uid}" Checked="CheckBox_Checked" Name="check1" />
                        </DataTemplate >
                    </DataGridTemplateColumn.CellTemplate>
                </DataGridTemplateColumn>
            </DataGrid.Columns>
        </DataGrid>
        <Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="388,126,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" />
    </Grid>

 

后台代码：

private void button1_Click(object sender, RoutedEventArgs e)
{

    foreach (stu item in dataGrid1.Items)
    {
        DataGridTemplateColumn templeColumn = dataGrid1.Columns[0] as DataGridTemplateColumn;

        FrameworkElement s = dataGrid1.Columns[0].GetCellContent(item);

        CheckBox cb = templeColumn.CellTemplate.FindName("check1", s) as CheckBox;

        if (cb.IsChecked == true)
            MessageBox.Show(Convert.ToString(cb.Tag));
    }
}
