先来张效果图

gridview 中嵌套gridview的原理是这样的，在父gridview中建一个摸板列，然后再模版列当中在放入子gridview，然后再父gridview的OnRowDataBound事件中在对子gridview进行数据绑定，首先要获取子gridview的控制权，然后进行数据绑定

 protected void gvList_RowDataBound(object sender, GridViewRowEventArgs e){utils util=new utils();HiddenField hf_year=(HiddenField)e.Row.FindControl("hf_year");if (hf_year != null){string path = hf_year.Value.ToString();if (e.Row.RowType == DataControlRowType.DataRow){GridView gvMajor = (GridView)e.Row.FindControl("gvMajor");gvMajor.DataSource = util.GetMajorName(path);gvMajor.DataBind();}}
