/// <summary>

private void InitializeComponent()
{
this.dgrdBuild.PageIndexChanged += new System.Web.UI.WebControls.DataGridPageChangedEventHandler(this.dgrdBuild_PageIndexChanged);
this.btnSee.ServerClick += new System.EventHandler(this.btnSee_ServerClick);
this.Load += new System.EventHandler(this.Page_Load); }
private void btnSee_ServerClick(object sender, System.EventArgs e)
{
this.Response.Redirect("Default.aspx?id=" + this.iCoum);
}

你直接在VS.net的设计状态下添加按钮的click事件很容易(双击按钮)。
新增加窗体后，form是自动添加的。

1、
this.btnSee.ServerClick += new System.EventHandler(this.btnSee_ServerClick);这个是什么意思?直接双地击时里面就是没有任何代码啊!!!,就是说按钮的click与过程QR在什么时候联系上呢?2、新增加窗体后，form是自动添加的。？？？
那为什么我增加时都没有看到呢？table又是如何增加呢？糊涂中。

不知道你们有没下载先锋论坛试例。。打开reg.aspx单元就明白我的意思哎。。刚学，什么都不懂。

1 事件委托（相当于事件通知）
2 vs.net里，新增页面，webform自动生成
3 建议代码和页面分离

代码都在这里：（aspx.cs)

protected void qr(object sender, EventArgs e)OnClick="qr"正常的应该是页面：<asp:Button id="Button1" style="Z-INDEX: 101; LEFT: 123px; POSITION: absolute; TOP: 122px" runat="server" Text="确定" Width="218px" Height="40px"></asp:Button>后台代码：private void Button1_Click(object sender, System.EventArgs e)
{

}

调试易

看例子:在设计及代码中什么找不到呢????
