我想选择后期类型后自动加载相应的值到gridview中去，不知道具体怎么弄了，有哪位大侠知道，先做添加功能，然后当我修改的时候，在一列中有checklist的集合，我怎么去判断后显示出来;gridview datatable 

解决方案 »

  1.   


    DataTable dt= new DataTable();
    DataRow dr=dt.NewRow();
    dr["typename"]= "值";
    dt.Rows.Add(dr);
    dt.AcceptChanges();
    gvw.DataSource=dt;
    gvw.DataBind();
      

  2.   


    不行，dr[“typename”]不属于表，这个周期类型就是复选框的值 ，但它修改的时候是从数据库中获取的，怎么弄呢
      

  3.   

    dr["typeName"] 是代表数据绑定到控件上对应你的代码给出的名字
          <asp:Label ID="typename" runat="server"></asp:Label>你是绑定到这个上面 所以我才写的TypeName至于绑定的Eval("typeName") 你自己应该知道些吧?
