看例子:在设计及代码中什么找不到呢????

[noall]

1、在看先锋论坛例子时reg.aspx时

按钮中的click事件在哪设计呢?

在html中看到是这样的:
<asp:button text="确定" OnClick="qr" runat="server" class="buttonface" ID="Button1" style="BORDER-RIGHT: #000000 1px solid; BORDER-TOP: #000000 1px solid; BORDER-LEFT: #000000 1px solid; BORDER-BOTTOM: #000000 1px solid; BACKGROUND-COLOR: #fffffd" />

在设计写了一个qr的过程.可在什么地方将qr设置为按钮的click呢?

2、新增加的web窗体是属于document，那form从哪增加？

[dongbeiren]

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)
{

}

[dongbeiren]

没明白你的意思

[树猫]

如果是 服务器端 button，在设计页面上 双击那个按钮 就可以进入其事件过程(视图与代码分离)

[树猫]

/// <summary>
/// 设计器支持所需的方法 - 不要使用代码编辑器修改
/// 此方法的内容。
/// </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);
}

[gshope]

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。。。。。。。。。。

[noall]

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。

[树猫]

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

在aspx.cs中就看不出那个确定按钮什么时候跟过程qr连在一起了呢？？？？？

代码跟页面是分离的吧。
