repeater嵌套的问题

Question

<asp:Repeater ID="rptTransmit_zx6b" runat="server" OnItemDataBound="rptTransmit_zx6b_ItemDataBound"
EnableViewState="False">
<ItemTemplate>
<div class="pan_link">
<ul>
<h1>
<a href='Transmit.aspx?id=<%# Eval("TRANSMIT_ID")%>'>
<%# Eval("NAME")%>
</a>
</h1>
<li class="line_pan01">
<ol>
<asp:Repeater ID="rptTask_zx6b" runat="server">
<ItemTemplate>
<li><a href='topology.aspx?id=<%# Eval("TASK_ID")%>' title='<%#Eval("NAME") %>
<%# CutString(Convert.ToString(Eval("NAME")), 3)%>
</a>
<p id='task<%# Eval("TASK_ID")%>'>
<%#FormatString(Eval("UP_FREQUENCY"))%>
</p>
</li>
</ItemTemplate>
</asp:Repeater>
</ol>
<div id="div_zx6b" runat="server" />
<asp:PlaceHolder ID="ph_zx6b" runat="server"></asp:PlaceHolder>
</li>
</ul>
</div>
</ItemTemplate>
</asp:Repeater>我怎么样把CutString(Convert.ToString(Eval("NAME")), 3)%>中的3改成rptTask_zx6b的当前绑定的记录数。记录数不固定

Answer 1

也就是，子repeater中的CutString需要子repeater的记录数。

Answer 2

建议你把 <a href='topology.aspx?id= <%# Eval("TASK_ID")%>' title=' <%#Eval("NAME") %> 
<%# CutString(Convert.ToString(Eval("NAME")), 3)%>这句换成个literal控件在CS代码里生成HTML
或者 修改一下绑定rptTask_zx6b的sql，那个sql加多一列用来计算这个sql的记录数子查询，
<%# CutString(Convert.ToString(Eval("NAME")), Eval("count"))%>

Answer 3

<%# CutString(Convert.ToString(Eval("NAME")), Eval("rptTask_zx6b"))%>在后台rptTask_zx6b设为共有的,
在将绑定的总数赋给rptTask_zx6b

Answer 5

<%# this.rptTask_zx6b.Items.Count + 1%> 

Answer 6

<%# CutString(Convert.ToString(Eval("NAME")), "this.rptTask_zx6b.Items.Count + 1")%>试试 

Answer 7

 把3换成一个方法：GetCount();
public int GetCount(){
     string sql = "select count(*) from 表  ";
     //查询记录数，条件要和你绑定repeater的条件一样     return Convert.ToInt32(查询到的结果);
}             

Answer 8

3  用变量就可以了，变量的修饰符 至少是 protected然后 在Repeater  绑定的时候 对数据源求 记录数，然后赋值给变量即可
 

Answer 9

CutString(Convert.ToString(Eval("NAME")), 后台方法返回记录数）

Answer 10

<%# CutString(Convert.ToString(Eval("NAME")), rptTask_zx6b.Items.Count + 1)%> 

Answer 11

可以现在后台得到值
在绑定到前台啊~~
CutString(Convert.ToString(Eval("NAME")), <%= intcount%>)%>public int intcount=0;
intcount=条数~~

Answer 12

<%# CutString(Convert.ToString(Eval("NAME")), 3)%> 换成  <%# CutString(Convert.ToString(Eval("NAME")), GetCount())%> 在后台写：Public int GetCount(){
         string sql = "select count(*) from table where "+//有条件就加;
          SqlConnection con = new SqlConnection();
          SqlCommend cmd = new SqlCommend();
          ......//自己写
            //最后得到查询的结果，就是你要的记录数
           //返回给页面
          return Convert.ToInt32(cmd.ExecuteScalar());
