//2.用sql中的case Gender when 1 then '男' else '女' end显示
//3.在后台写方法,前台调用显示,如Format(object item,string type)

2.cs代码

public class GridFormat : System.Web.UI.Page
    {
        protected System.Web.UI.WebControls.DataGrid DataGrid1;

        private void Page_Load(object sender, System.EventArgs e)
        {
            //1.用<%# DataBinder.Eval(Container.DataItem,"MaritalStatus").ToString()=="1"?"已婚":"未婚" %>方式显示
            //2.用sql中的case Gender when 1 then '男' else '女' end显示
            //3.在后台写方法,前台调用显示,如Format(object item,string type)
            //4.DataGrid1_ItemDataBound
            DataBind();
for(int i=0; i < DataGrid1.Items.Count; i++)
   {
    if(DataGrid1.Items[i].Cells[2].Text=="男")
    {
     DataGrid1.Items[i].Cells[2].ForeColor = System.Drawing.Color.Red;
    }
   }

        }

        GetDataSet

        DataBind

        Format

        Web Form Designer generated code

      DataGrid1_ItemDataBound
    }
3.数据库教本

if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[FormatGrid]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[FormatGrid]
GO

CREATE TABLE [dbo].[FormatGrid] (
    [UserID] [int] NULL ,
    [Degree] [int] NULL ,
    [Gender] [int] NULL ,
    [MaritalStatus] [int] NULL ,
    [Description] [nvarchar] (500) COLLATE Chinese_PRC_CI_AS NULL
) ON [PRIMARY]
GO

--测试数据
insert into FormatGrid(UserID,Degree,Gender,MaritalStatus,Description) values(1,1,1,0,'可以读取流。读取是从流到数据结构（如字节数组）的数据传输。')
insert into FormatGrid(UserID,Degree,Gender,MaritalStatus,Description) values(2,2,0,1,'可以写入流。写入是从数据结构到流的数据传输。')
insert into FormatGrid(UserID,Degree,Gender,MaritalStatus,Description) values(3,3,1,0,'流可以支持查找。查找是对流内的当前位置进行查询和修改。查找功能取决于流具有的后备存储区类型。例如，网络流没有当前位置的统一概念，因此一般不支持查找。')
insert into FormatGrid(UserID,Degree,Gender,MaritalStatus,Description) values(4,4,0,1,'小山哥')
insert into FormatGrid(UserID,Degree,Gender,MaritalStatus,Description) values(5,5,1,0,'山哥')
