C# GridView 怎样在前台绑定ID

不用，GridView的DataKey 可以办到

#region 删除
protected void LinkDel_Click(object sender, EventArgs e)
{
for (int i = 0; i < girdNews.Rows.Count; i++)
{
CheckBox chkNewsId = (CheckBox)girdNews.Rows[i].FindControl("chkNewsId");
int newsId=Convert.ToInt32(chkNewsId.Text);
if (chkNewsId.Checked)
{
newsBll.Delete(newsId);
}
}
GvDataBind();
}
#endregion

可以用GridView的DataKey

用隐藏控件绑定,然后遍历就可以了
