我的sql数据库中有10个问题。我得到它们并使用LinkButton以链接形式打印它们。现在我想分别生成每个问题的点击事件。
如何在ListView中生成LinkButton的OnClick事件。请轻松帮忙。

代码背后：
protected void ListView1_ItemCommand(object sender, ListViewCommandEventArgs e)
{
string userid = e.CommandArgument.ToString();
Response.Write("U:" + userid);
if (userid == "USER_3730")
{
Response.Redirect("bnbnbnbnbn.aspx");
}
if (userid == "USER_b163")
{
Response.Redirect("home.aspx");
}
}
