asp.net GridView中超链接的使用（带参数）

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
　　if (e.Row.RowType == DataControlRowType.DataRow)
{
　　 HyperLink btnlink = (HyperLink)e.Row.Cells[3].FindControl("hyperLink");
HiddenField hidderid = (HiddenField)e.Row.Cells[3].FindControl("log_id");//通过隐藏域获取要传递的参数
string url = string.Empty;
if (hidderid != null)
{
url = "~/ImageManage/LogPicDetails.aspx?id=" + hidderid.Value;
btnlink.NavigateUrl = url;
}
}
}

protected void LB_Ori_Click(object sender, EventArgs e)
{
LinkButton lbtn = (LinkButton)sender;
int imgID = int.Parse(lbtn.CommandArgument.ToString());
string url = "OrigImageShow.aspx?image_id=" + imgID;
url = Page.ResolveUrl(url);
Page.ClientScript.RegisterStartupScript(Page.GetType(), "messid", "");
}
