关于gridview

Question

gridview中autogeneratecolumns设置为false,在编辑列中写下列名在用手写语句绑定为什么只显示列名无内容?
gridview中OnDataBound属性有什么用?

Answer 1

<asp:GridView runat=server ID="gvEditData" AutoGenerateColumns="False" >
        <Columns>
           
            <asp:BoundField DataField="stuId" HeaderText="stuId" InsertVisible="False" ReadOnly="True"
                 />
            <asp:BoundField DataField="stuName" HeaderText="stuName"  />
            <asp:BoundField DataField="stuNo" HeaderText="stuNo" Sort/>
            <asp:CheckBoxField DataField="stuSex" HeaderText="stuSex"  />
            <asp:BoundField DataField="stuAge" HeaderText="stuAge"  />
            <asp:BoundField DataField="stuSeat" HeaderText="stuSeat"  />
            <asp:BoundField DataField="stuAddress" HeaderText="stuAddress"/>
        </Columns>
    </asp:GridView>aspx.csprotected void Page_Load(object sender, EventArgs e)
 {
   if(!IsPostback)
   {
     DataTable dt = DbQuery.getDataTable("select *  from student");
     gvTest.DataSource = dt;
     gvTest.DataBind()
   }
}DbQuery.cs
 public static DataTable getDataTable(string sql)
    {
        DataTable table = new DataTable();
        using (DbConnection conn = DbFactory.getConnection())
        {
            conn.Open();
            DbCommand cmd = DbFactory.getCommand();
            DbDataAdapter adp = DbFactory.getDataAdpter();
            cmd.Connection = conn;
            cmd.CommandText = sql;
            adp.SelectCommand = cmd;
            adp.Fill(table);
        }
        return table;
    }按上边的例子··如果还绑不上··那就是数据库里没数据。。
