ADO.NET,你的极限是什么?--ADO.NET之另类绑定

        在.NET应用中，数据库的成分不仅是整个.NET框架重要的部分,也是设计页面和后台的关键.

        ADO.NET你的极限是什么?

1. 页面文件有两个TEXTBOX控件用来设置查找范围。下面一个DATAGRID，用来绑定数据库的数据。

2.后台代码片段:

public partial class FinanceReport : PageBase
{
     public static String CONN = System.Configuration.ConfigurationManager.AppSettings.Get( "ConnectionString");

     protected void Page_Load( object sender, EventArgs e)
    {
        PageBegin( true, false);

         if (IsPostBack)
             return;

        FromDate.Text = DateTime.Now.Year.ToString() + "-1-1";
        ToDate.Text = (DateTime.Now.Year + 1).ToString() + "-1-1";

        PageFill();
    }
     protected void QueryButton_Click( object sender, EventArgs e)
    {
         if (DateUtil.IsDateTime(FromDate.Text) == false || DateUtil.IsDateTime(FromDate.Text) == false)
        {
            Session[ "CM_report_FromDate"] = "";
            Session[ "CM_report_ToDate"] = "";
        }
         else
        {
            Session[ "CM_report_FromDate"] = FromDate.Text;
            Session[ "CM_report_ToDate"] = ToDate.Text;
        }

        BuildTable();

    }
     protected void PageFill()
    {
         if (Session[ "CM_Year"] != null)
        {
            FromDate.Text = Session[ "CM_Year"] + "-1-1";
            ToDate.Text = int.Parse(Session[ "CM_Year"].ToString()) + 1 + "-1-1";
        }

         if (Session[ "CM_report_FromDate"] != null)
            FromDate.Text = Session[ "CM_report_FromDate"].ToString();
         if (Session[ "CM_report_ToDate"] != null)
            ToDate.Text = Session[ "CM_report_ToDate"].ToString();

        BuildTable();
    }
     protected void BuildTable()
    {
        SqlConnection conn = new SqlConnection();
        conn.ConnectionString = CONN;
        SqlCommand command = new SqlCommand();

        command.CommandText = "CM_Test";
        command.CommandType = CommandType.StoredProcedure;
        command.Connection = conn;

        SqlParameter param = new SqlParameter( "@FromDate", SqlDbType.DateTime);
         if (DateUtil.IsDateTime(FromDate.Text) == false)
        {
            param.Value = DateTime.Parse(DateTime.Now.Year.ToString() + "-1-1");
        }
         else
        {
            param.Value = DateTime.Parse(FromDate.Text);
        }
        command.Parameters.Add(param);
        param = new SqlParameter( "@ToDate", SqlDbType.DateTime);
         if (DateUtil.IsDateTime(ToDate.Text) == false)
        {
            param.Value = DateTime.Parse((DateTime.Now.Year + 1).ToString() + "-1-1");
        }
         else
        {
            param.Value = DateTime.Parse(ToDate.Text);
        }
        command.Parameters.Add(param);

        DataSet ds = new DataSet();
        SqlDataAdapter da = new SqlDataAdapter();
        da.SelectCommand = command;
        da.Fill(ds);
        DG.DataSource = ds;
        DG.DataBind();
    }
}

说明：后台代码中设计时间范围的小技巧很好用，借助JS，点击TEXTBOX控件的时候就会激发封装好的日历，然后选择日期，就可以自动完成填充了。下面就是绑定了。调用了“CM_Test”

3.数据库存储过程，精彩的来了：

说明：。。。这个存储过程直接搞定这个页面，数据库也可以这样完成，我也是第一次接触这样的存储过程。里面带"Money"的变量都是数据库存储金额的类型，这个页面的功能是统计功能。红字的就直接显示在表里面了--即“统计项”；ic--即集成合同；asb--即ASB合同；Sales--即销售合同。
