法一：最常用最变通的方法在为其绑定数据的时候，设置DataKeyNames 属性，如下： string[] id = { "ID" }; gridview .DataKeyNames = id;在其行事件里操作数据需要ID时，直接读取gridview 中的数据键值，如下： int id = Convert.ToInt32((gridview .DataKeys[e.RowIndex]).Value);法二：在显示数据的时候将ID放在隐藏域里，如下： ' />在其行事件里操作数据需要ID时，用FindControl，如下： int id = Convert.ToInt32((HiddenField)e.Row.FindControl("hfldID")).Value);
