cs   //GridView1_RowDataBound
        protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow && e.Row.RowType != DataControlRowType.Header && e.Row.RowType != DataControlRowType.Footer)
            {
                GridView gv = (GridView)e.Row.FindControl("gv_company_list");
                string kw = DataBinder.Eval(e.Row.DataItem, "companyName").ToString();
               gv.DataSource = rbiB.listCompany();
               gv.DataBind();
                            }
        }
        protected void gv_company_list_RowDataBound(object sender, GridViewRowEventArgs e)
        {             if (e.Row.RowType == DataControlRowType.DataRow && e.Row.RowType != DataControlRowType.Header && e.Row.RowType != DataControlRowType.Footer)
            {
                GridView gv = (GridView)e.Row.FindControl("gv_job_list");
                string userNo = DataBinder.Eval(e.Row.DataItem, "userNo").ToString();
                 gv.DataSource = rjB.FindRecruitJobByUserNoTitle(userNo, jobTitle);
                 gv.DataBind();            }
        }
 怎样在 gv_company_list_RowDataBound 里得到第一层jobTitle的值啊？

Answer 2

try:        protected void gv_company_list_RowDataBound(object sender, GridViewRowEventArgs e)
        {
             if (e.Row.RowType == DataControlRowType.DataRow)
            {
                GridView gv_company = e.Row.NamingContainer as GridView;
                if(gv_company != null)
                {
                    GridViewRow gvr = gv_company.NamingContainer as GridViewRow;
                    if(gvr != null)
                    {
                         string jobTitle = gvr.Cells[1].Text;
                         // to do...
                    }
                }
                GridView gv = (GridView)e.Row.FindControl("gv_job_list");
                string userNo = DataBinder.Eval(e.Row.DataItem, "userNo").ToString();
                 gv.DataSource = rjB.FindRecruitJobByUserNoTitle(userNo, jobTitle);
                 gv.DataBind();            }
        }

Answer 3

 protected void gv_company_list_RowDataBound(object sender, GridViewRowEventArgs e)
        {             if (e.Row.RowType == DataControlRowType.DataRow && e.Row.RowType != DataControlRowType.Header && e.Row.RowType != DataControlRowType.Footer)
            {               GridViewRow parentRow = (sender as GridView).Parent as GridViewRow;
               // ...            }
        }思路是这样,代码我没试过..

    protected void   gv_company_list_RowDataBound(object sender, GridViewRowEventArgs e)
    {
            GridView gv_company_list;   
            if (e.Row.RowType == DataControlRowType.DataRow)   
            {   
                gv_company_list = e.Row.FindControl("gv_company_list") as GridView;   
                if (gv_company_list != null)   
                {   
                    string jobTitle= DataBinder.Eval((gv_company_list.NamingContainer as GridViewRow).DataItem, "jobTitle").ToString();
                    //你的代码                    
                }   
            }
