Question

Hai Pupils，

     I am a beginner in Dot net Domain.Presently Im creating a web portal for one of our client.In my portal i have displayed the News headline and a button for details in a Grid view. when i click on the button it has to show the detailed news from DB in another grid view. I have done a code on it.,but it shows some error.I have displayed the code below.Please help me to overcome this problem.

我的代码是

protected void GridView1_RowDataBound（object sender，GridViewRowEventArgs e） { if（e.Row.RowType！= DataControlRowType.Header＆amp;＆amp; e.Row.RowType！= DataControlRowType.Footer＆amp;＆amp; e.Row.RowType！= DataControlRowType.Pager） { 按钮btn =（按钮）e.Row.FindControl（“Button12”）; btn.CommandArgument = e.Row.RowIndex.ToString（）; } } protected void GridView1_RowCommand（object sender，GridViewCommandEventArgs e） { if（e.CommandName ==“newsbtn”） { int index = int.Parse（e.CommandArgument.ToString（））; string key = GridView2.DataKeys [index] .Value.ToString（）;

        SqlDataAdapter da = new SqlDataAdapter("select **img,news,detail** from News where news=@n", connect.con());
        da.SelectCommand.Parameters.AddWithValue("@n", key);
        da.Fill(ds, "more");

        //if (!IsPostBack)
        //{
            GridView1.DataSource = ds;
            GridView1.DataBind();
        //}
    }
}

它显示的错误是：

DataBinding：'System.Data.DataRowView'不包含名称为'detail'的属性。

可能这些将有助于 1. Master/Detail Using a Selectable Master GridView with a Details DetailView使用Gridview而不是DetailsView来显示子记录
2.或者你可以尝试更高级的方法GridView control to show master-child or master-slave data, written in c#, asp.net, and javascript

干杯

如何根据我在Gridview控件中选择的值从数据库检索数据到Gridview？
