Vs2005新开始

昨天msdn发布Announcing the Release of Visual Studio 2005 Beta 1 ,下载回来试用.
在还在测试着GridView和Data Source Controls等等处理数据的组件.11:40:28
就正如 More Load, Less Code with the Data Enhancements of ASP.NET 2.0说的:
The advent of data source controls do not make ADO.NET objects unnecessary; they are still essential pieces of the .NET Framework, but they have been removed from prime time and pushed to the back-end infrastructure of most common data binding operations.

                          Figure 2 Data Source Controls, GridView, and Data Sources     

         Ado. net已经没有以前那么重要了,以后我们用得更多将会是DataSource. DataSource共有六种类型, 这六种类型分两类:
  Tabular Controls:         AccessDataSource,  DataSetDataSource,  ObjectDataSource,  SqlDataSource
  Hierarchical Controls:  SiteMapDataSource, XmlDataSource
         DataSource在Vs2005里面设置DataSource是一件非常容易的事情

<asp:TextBox runat="server" ID="EmpID" Text="3" />
<asp:SqlDataSource runat="server" 
  ID
="MySource" 
  ConnectionString
="SERVER=(local);
  DATABASE=northwind;Integrated Security=SSPI;"

  SelectCommand
="SELECT * FROM employees WHERE employeeid > @MinID">
  
<SelectParameters>
     
<asp:ControlParameter Name="MinID" 
          ControlId
="EmpID" 
          PropertyName
="Text" />
  
</SelectParameters>
</asp:SqlDataSource>

设置好DataSource, 主要是ConnectionString,  SelectCommand.(除了Select,还有select, insert, update, and delete)
DridView设置DataSourceId="MySource" .就可以把绑定数据,显示出来.
