稳扎稳打Silverlight(17) - 2.0数据之详解DataGrid, 详解ListBox


作者：webabcd


介绍
Silverlight 2.0 详解DataGrid, 绑定数据到ListBox：
    AutoGenerateColumns - 是否根据数据源自动生成列
    RowDetailsVisibilityMode - 显示相应的行的详细数据时所使用的显示模式
    DataGrid.Columns - 手工定义DataGrid的列
    DataGrid.RowDetailsTemplate - 用于显示相应的行的详细数据的模板
    AreRowDetailsFrozen - 是否冻结 RowDetailsTemplate
    GridLinesVisibility - 表格分隔线的显示方式
    RowBackground - 奇数数据行背景
    AlternatingRowBackground - 偶数数据行背景
    IsReadOnly - 单元格是否只读
    FrozenColumnCount - 表格所冻结的列的总数（从左边开始数）
    SelectionMode - 行的选中模式
    CanUserReorderColumns - 是否允许拖动列
    CanUserResizeColumns - 是否允许改变列的宽度
    CanUserSortColumns - 是否允许列的排序
    VerticalGridLinesBrush - 改变表格的垂直分隔线的 Brush
    HorizontalGridLinesBrush - 改变表格的水平分隔线的 Brush
    HeadersVisibility - 表头（包括列头和行头）的显示方式
