ASP：RUNAT =服务器进行动态控制 [英] ASP: runat=server for dynamic control

问题描述

在Page_Load方法创建一些控件，根据各种条件。我想与这些控件注册服务器端code。然而，在过去的一部分，我需要声明我的控件服务器控件。这通常是由RUNAT =服务器完成的，但我不知道如何设置在C＃code此属性。 myControl.Attributes.Add（RUNAT，服务器）不会做的伎俩。这一件作品，这意味着，当我点击它的测试方​​法被调用：

In the Page_Load method I create a couple of controls, based on various conditions. I would like to register server side code with those controls. However, for the last part I need to declare my controls as server controls. This is normally done by runat=server, but I don't know how to set this attribute in the C# code. myControl.Attributes.Add("runat", "server") does not do the trick. This one works, meaning that the "test" method is called when I click on it:

<asp:LinkButton ID="LinkButton1" runat="server" OnClick="test">testtext</asp:LinkButton>

这一个不工作：

            LinkButton lb = new LinkButton();
            lb.ID = "LinkButton1";
            lb.OnClientClick = "test";
            lb.Text = "testtext";
            lb.Attributes.Add("runat", "server");

我可以点击它，并在页面加载，但试验方法不被调用。

I can click on it, and the page is loaded, but the test-method is not called.

任何提示？

推荐答案

您几乎得到了它的权利。只是一对夫妇的事情：

You almost got it right. Just a couple things:

• 当你手动实例化服务器控件，没有必要添加 =服务器属性。这是唯一使用的ASP.NET页面分析程序从其他标记区分服务器控件一个特殊的属性。


• 标记中的的OnClick 属性对应于点击服务器端事件，您挂钩使用 + = 运营商。 （另外，在标记中的的OnClientClick 属性对应于的onclick 的客户端属性，它通常包含的JavaScript code片段。事实上，的OnClick 不符合的onclick 是不可否认有点混乱。）

• When you manually instantiate a server control, there's no need to add the runat="server" attribute. This is a special attribute that's used only by the ASP.NET page parser to distinguish server controls from other markup.
• The OnClick attribute in markup corresponds to the Click server-side event, which you hook up using the += operator. (On the other hand, the OnClientClick attribute in markup corresponds to the onclick client-side attribute, which typically contains a snippet of JavaScript code. The fact that OnClick doesn't correspond to onclick is admittedly a bit confusing.)

因此​​：

LinkButton lb = new LinkButton();
lb.ID = "LinkButton1";
lb.Click += test;
lb.Text = "testtext";

和事件处理函数（你甚至可以使私人如果有，将其从标记的引用）：

And your event handler (which you can even make private if there are no references to it from markup):

protected void test(object sender, EventArgs e)
{
}
