四个链接按钮的唯一ID [英] unique id's for four link button

问题描述

您好，我正在制作一个asp.net Web应用程序

我只需单击一个按钮，即可在运行时动态创建四个链接按钮.
现在，我想使用所有四个链接按钮来做不同的工作..
如何确定我要单击哪个链接按钮?如何生成四个链接按钮的不同ID，以便可以进行点击事件
所有四个链接按钮中的一个.

我在运行时为动态创建的链接按钮编写的代码是

Hello to all i making an asp.net web application

I have created four link button dynamically at run time on a single click of a button.
Now I want to do different works with all four link button..
How do I identify which link button I am clicking? How can I generate different IDs of four link buttons so that I can make click event
of all four link button.

My coding for dynamically created link buttons at run time is this

protected void btnacces_Click(object sender, EventArgs e)
   {
       //take oledb command
       OleDbCommand cmd = conn.CreateCommand();
       cmd.CommandText = "select * from subcategory where cateid=2";
       //take oledb datareadreader
       OleDbDataReader dr;
       dr = cmd.ExecuteReader();
       while(dr.Read())
       {
           LinkButton lk=new LinkButton();
           lk.Text=dr.GetString(2);
           Panel1.Controls.Add(lk);
           Panel1.Controls.Add(new LiteralControl("<br>"));
       }
   }

推荐答案

int i=1;
while(dr.Read())
{
  LinkButton lk=new LinkButton();

  lk.ID = "lkbtn"+i.ToString();

  lk.Text=dr.GetString(2);
  Panel1.Controls.Add(lk);
  Panel1.Controls.Add(new LiteralControl(""));
  i++;
}

对所有链接按钮使用comman事件处理程序，并根据其ID进行区分.
谢谢.

Use comman event handler for all link button and differentiate it over its IDs.
BY thanks.

int i=1;
while(dr.Read())
{
LinkButton lk=new LinkButton();
lk.ID = "lkbtn"+i.ToString();
lk.Text=dr.GetString(2);
Panel1.Controls.Add(lk);
Panel1.Controls.Add(new LiteralControl("<br>"));
i++;
}
Use comman event handler for all link button and differencate it over its IDs.
