超链接点击识别！ [英] Hyperlink click recognition !

问题描述

Visual Studio，ASP.NET

朋友，
我使用PlaceHolder控件，并通过以下代码在Page_load中添加了两个HyperLink控件:

visual studio, ASP.NET

hi friends,
I use PlaceHolder control and add two HyperLink controls in Page_load by this code:

System.Web.UI.WebControls.HyperLink hl = new HyperLink();
PlaceHolder1.Controls.Add(hl);

hl = new HyperLink();
PlaceHolder1.Controls.Add(hl);

现在的问题是我应该如何确认用户单击了哪个超链接！ 例如，使用某种方式在超链接单击后更改请求的查询或更改会话！
对不起，我的英语解释不好.
我将不胜感激.

Now the problem is how should i recongnize which hyperlink did user clicked !!??
for example use some way to change requesting query or changing session after hyperlink click !

Sorry for bad explanation and my bad english.
i''ll appreciate any help.
thanks in advanced.

推荐答案

使用HyperLink 的ID 或Text 属性，您可以了解实际单击了哪个HyperLink.试试这个:

With the ID or Text property of HyperLink you can come to know which HyperLink is clicked actually. Try this:

HyperLink hl = new HyperLink();
hl.ID = "HyperLnk1";
hl.Text = "HyperLnkText1";
PlaceHolder1.Controls.Add(hl);

hl = new HyperLink();
hl.ID = "HyperLnk2";
hl.Text = "HyperLnkText2";
PlaceHolder1.Controls.Add(hl);

现在，您可以使用Text 或ID 属性识别超链接.

Now you can recognize the hyperlinks using Text or ID property.

如果要订阅单击事件，我宁愿使用ASP LinkBut​​ton控件，也不愿使用常规的超链接.示例:

If you want to subscribe to a click event I would rather use the ASP LinkButton control than a regular hyperlink. Example:

protected void Page_Load(object sender, EventArgs e)
{
    LinkButton linkButton = new LinkButton();
    linkButton.Text       = "LinkButton";
    linkButton.Click     += new EventHandler(linkButton_Click);

    PlaceHolder1.Controls.Add(linkButton);
}

void linkButton_Click(object sender, EventArgs e)
{
    LinkButton linkButton = sender as LinkButton;

    if (linkButton.Text == "LinkButton")
    {
        // Open a different page
        Response.Redirect("WebForm2.aspx");
    }
}
