gridView和sqlDataSource的使用
我使用了以下两种不同的方式来实现对数据的编辑和删除
第一种方式：把主要的代码写在aspx页面内[实现了编辑和删除].cs文件内不需要添加任何代码
注：
1、 <add name="myTest" connectionString="Data source=.;Database=myTest;Integrated Security=True" providerName="System.Data.SqlClient" />
2、DataKeyNames="userid"这句如果少掉话会提示你缺少userid参数

DeleteCommand="Delete From users where userid=@userid"
SelectCommand="Select userid,username,sex from users"
InsertCommand="insert into users values(@username,@sex,@)"
UpdateCommand="Update users set username=@username,sex=@sex where userid=@userid">
<DeleteParameters>
<asp:Parameter Name="userid" Type="int32" />
</DeleteParameters>
<UpdateParameters>
<asp:Parameter Name="userid" Type="int32" />
<asp:Parameter Name="username" Type="String" />
<asp:Parameter Name="sex" Type="String" />
</UpdateParameters>
</asp:SqlDataSource>
<asp:GridView ID="gdTest" DataSourceID="userSource" DataKeyNames="userid" runat="server" AutoGenerateColumns="false" AllowPaging="true" AllowSorting="true" PageSize="3">
<Columns>
<asp:CommandField ShowDeleteButton="true" ShowEditButton="true" />
<asp:BoundField HeaderText="ID" DataField="userid" InsertVisible="false" ReadOnly="true" SortExpression="userid" />
<asp:BoundField HeaderText="Name" DataField="username" SortExpression="username" />
<asp:BoundField HeaderText="Sex" DataField="sex" SortExpression="sex" />
</Columns>
</asp:GridView>
