} 

    protected void lbView_Click(object sender, EventArgs e)
    {

    }

问题是当求职者单击“查找作业”按钮时，作业被列出， 但是“申请此作业”根本没有触发。

请帮忙。

你可以试试看

   LinkButton lnkButton = new LinkButton();
   lnkButton.ID = "lnkdynamicbutton"; 
   lnkButton.Text = "Apply for this job";
   lnkButton.Click += new System.EventHandler(lnkButton_Click);

protected void lnkButton_Click(object sender, EventArgs e)
{
    Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "script", "<script>alert('You Clicked me!!!')</script>");
}
