NetTiers学习笔记09---RADGrid + EntityDataSource设置默认排序, 及表格自动排序,分页的方法

前段时间虽然解决了排序和分页的问题,但始终没有解决默认排序的问题,
起初一直把焦点放在EntityDataSource的排序默认值上,但始终搞不定,
今天又花了不少时间Google和研究,终于通过设置RADGrid的默认排序,
把此问题解决了

 1       < rad:RadGrid  ID ="grid"  runat ="server"  AllowPaging ="True"  AllowSorting ="true"  GridLines ="None"

74               < asp:Parameter  Name ="RecordCount"  Direction ="Output"  Type ="Int32"   />
75           </ Parameters >
76       </ data:FmInvoicesDataSource >

关键部分
   <SortExpressions>
        <rad:GridSortExpression FieldName="F_No" SortOrder="Descending" />
   </SortExpressions>
设定RADGrid的默认排序

   <data:CustomParameter Name="OrderBy" ConvertEmptyStringToNull="true" />
可有可无,但不能在CustomParameter  的DefaultValue或Value 设值,要不然会无法自动排序
