gridview 怎样获取所选记录的关键字?
在删除记录的时候,我需要获取所选记录的关键字,用以前dataGrid的方法行不通,请问怎么解决?
[解决办法]
protected void gvNewsList_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
GridView gv = (GridView)sender;
int id = int.Parse(gv.DataKeys[e.RowIndex].Value.ToString());
News news = new News();
news.DeleteNewsByNewsID(id);
BindNewsList();
}
gridview 里加DataKeyNames= "newsid "

楼上正解

单个关键字：

多个关键字：
GridView1.DataKeys[nRowIndex].values[i]
