嵌套的repeater，怎么每行求和，放在每行最后一个单元格
- HTML code
<table border="1" align="left" cellspacing="0" bordercolor="#196ce3" rules="all" style="border: 1px solid #196ce3; border-collapse: collapse; height:237px; width: 1001px;"> <tr> <td colspan="5" align="center" height="60"><strong>成绩表</strong></td> </tr> <tr> <td rowspan="2" align="center" width="150"> <strong> 得分情况 </strong> </td> <td colspan="4" align="center"><strong> c程序设计 </strong></td> </tr> <tr > <td align="center" style="cursor:hand;"> <strong>简单题</strong></td> <td align="center" style="cursor:hand;"> <strong>中等题</strong></td> <td align="center" style="cursor:hand;"> <strong>难题</strong></td> <td align="center" style="cursor:hand;"> <strong>总分</strong></td> </tr> <asp:Repeater ID="Repeater4" runat="server" onitemdatabound="Repeater4_ItemDataBound" > <ItemTemplate> <tr> <td width="150" align="center" height="30"><%# Eval("chapter").ToString() %></td> <asp:Repeater ID="Repeater3" runat="server" > <ItemTemplate> <td width="50" align="center"><strong> <%# Eval("e_score").ToString() %></strong></td> <td width="50" align="center"><strong> <%# Eval("m_score").ToString()%></strong></td> <td width="50" align="center"><strong> <%# Eval("d_score").ToString()%></strong></td> <td width="50" align="center"><strong> <% # [color=#FF0000]这里是要绑定的总分[/color] %></strong></td> </ItemTemplate> </asp:Repeater> </tr> </ItemTemplate> </asp:Repeater> </table>这是前台代码。 红色字体就是要绑定的，就是e_score + m_score + d_score 放在那里
- C# code
protected void Page_Load(object sender, EventArgs e) { if(!IsPostBack) { Repeater4Bind(); } } protected void Repeater4Bind() { string sql = "select distinct chapter from student_score where sid='" + Session["uid"].ToString() + "' order by chapter"; Common comm = new Common(); DataSet ds = comm.GetDataSet(sql); Repeater4.DataSource = ds.Tables[0].DefaultView; Repeater4.DataBind(); } protected void Repeater4_ItemDataBound(object sender, RepeaterItemEventArgs e) { if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) { Repeater rep = e.Item.FindControl("Repeater3") as Repeater; // 找到里层的repeater对象 string sql = "select * from student_score where chapter = '" + DataBinder.Eval(e.Item.DataItem, "chapter") + "' and sid='" + Session["uid"].ToString() + "' "; Common comm = new Common(); DataSet ds = comm.GetDataSet(sql); rep.DataSource = ds.Tables[0].DefaultView; rep.DataBind(); } }
这是后台代码、、求高手指点迷津 希望步骤详细点 本人刚学.NET不久 有点小白 谢谢！

<td width="50" align="center"><strong> <%# Eval("e_score").ToString() %></strong></td>
<td width="50" align="center"><strong> <%# Eval("m_score").ToString()%></strong></td>
<td width="50" align="center"><strong> <%# Eval("d_score").ToString()%></strong></td>
<td width="50" align="center"><strong> <% # 这里是要绑定的总分 %></strong></td>
你绑定的这里，一种方法是用label控件来显示。比如<%# Eval("e_score").ToString() %>
改成<asp:Label ID="Label1" runat="server"
Text='<%# Eval("e_score").ToString() %>'></asp:Label>
这样，在前体显示的效果没有区别，后台可以在ItemDataBind（）事件中，用findControl方法找到控件，然后取值，计算，给最后个总分显示的赋值。
还有就是可以在sql查询的视乎就计算，根据查询的结果直接绑定也可以。
前台绑定查询的Id值，后台方法计算返回等等都是可以的.

1<%# (int.Parse(Eval("d_score").ToString()) +int.Parse( Eval("d_score").ToString()) + int.Parse(Eval("d_score").ToString()).ToString())%>
2
sql ='select d_score+e_score+m_score as sum_score from student_score where chapter ='
<%# Eval("sum_score").ToString()%>
