• Developer Express XtraGrid使用技巧


    1.基本grid的用法

    1.1 gridControl-->view-->gridView

    绑定到grid上的字段可以拖动删除,在任意字段上右键点column chooser 可以将删除的字段添加进来

    字段上右键选择实现选定需要的信息和排序

    字段上右键选择分组(group by   column),也可以直接将字段拖到上面实现分组

    字段上右键选择group by box后可以取消分组栏,(不能实现拖动分组,但可以选择分组)

    字段上右键选择best fit可以实现该字段最佳宽度(便于查看)

    1.2 gridControl-->view-->cardView

    以卡片形式存放数据

    可以自己设定过滤选项

    1.3 gridControl-->view-->banderGridView

    将字段分段显示,前提是给gridControl先绑定一个dataset

    动态绑定的时候不能分段,也不能分行

    1.3 gridControl-->view-->advBanderGridView

    高级分段显示,动态绑定的字段可以在前台向下拖动后分段,但效果不好,相当于分行显示的样子

    1.4 else

    可以通过create ner view增加一个view ,但程序只显示你选定的view

    zoom的使用   快速上升,也就是选择子项后单独显示(上到最高显示)

    1.5 feature browser

    -->priview   可以指定在每行中预览的字段

    -->filtering 可以自动过滤(optingview.showAutoFiterRow)

    1.7 Master-Detail 绑定的问题
    首先在gridControl1中指定dataSource 的绑定是主表
    然后在level设计器中添加层(retrieve details)
    最后用代码绑定:
    using (SqlConnection con = new SqlConnection(SqlHepler.CONN_STRING))
                 {
                     //SqlDataAdapter sda1 = new SqlDataAdapter("select * from Orders",con);
                     //sda1.Fill(this.northwindDataSet.Orders);

                     SqlDataAdapter sda2 = new SqlDataAdapter("select * from [Order Details]",con);
                     sda2.Fill(this.northwindDataSet.Order_Details);
                 }

    1.8 summary的用法

                 //If the GridOptionsView.ShowFooter option is set,
                 //the summary(of course some else can ) can be displayed within the footer cell.
                 gridView1.OptionsView.ShowFooter = true;

                 //初始化,也可以不用指定
                 colOrderID.SummaryItem.FieldName = "OrderID";
                 colOrderID.SummaryItem.SummaryType = DevExpress.Data.SummaryItemType.Count;

    2.XtraGrid的打印

    借用别人写的一个类

    class DevPrint
         {

             //*********************字段*********************
             private string pageHeaderName="";
             private string pageFooterName="";

             private DevExpress.XtraPrinting.PageHeaderArea PHA = new DevExpress.XtraPrinting.PageHeaderArea();
             private DevExpress.XtraPrinting.PageFooterArea PFA = new DevExpress.XtraPrinting.PageFooterArea();
             //*********************字段*********************
