推荐答案

yep
使用gridview RowDataBound

yep
use gridview RowDataBound

protected void grv_RowDataBound(object sender, GridViewRowEventArgs e)
{
    switch (e.Row.RowState)
    {
        case DataControlRowState.Normal:
        case DataControlRowState.Alternate:
        case DataControlRowState.Edit:
            int idField = Convert.ToInt16(DataBinder.Eval(e.Row.DataItem, "idField"));
            Repeater rep= (Repeater )e.Row.FindControl("idRepeater");
            rep.DataSource = yourdatasource;
            rep.DataBind();
            break;
    }
}

我不知道您是否总是需要绑定或仅在编辑模式下需要绑定.

使用不同的情况来更改行为

i don''t know if u need the bind always or only in edit mode.

use different cases to change that behaviour

<asp:gridview id="GrdJobSht" runat="server" autogeneratecolumns="False" datasourceid="GetJobSheetDATA" xmlns:asp="#unknown">
 <columns>
  <asp:templatefield>
    <itemtemplate>  
      <table>
      <tr>
      <td rowspan="5" class="style4">
       <asp:image id="ProdImage" runat="server" height="152px" imageurl="<%# String.Format(ResolveUrl("ProductImage.ashx")+"{0}{1}","?id=",Eval("propImageId"))%>" style="margin-left: 0px" width="172px" bordercolor="Silver" borderstyle="Double" borderwidth="10pt" /> 
</td>                                              
</tr>
<tr>
<td class="style5">
<asp:label id="Label1" runat="server" text="Product ID:" font-italic="True">
 Font-Names="Times New Roman" Font-Size="Medium"></asp:label>
 </td>
 <td>
  <asp:label id="lblProdid" runat="server" text="<%# Eval("propProdId") %>"></asp:label>
 </td>
 </tr>
 <tr>
 <td class="style5">
 <asp:label id="Label2" runat="server" text="Description:" font-italic="True">
 Font-Names="Times New Roman" Font-Size="Medium"></asp:label>
 </td>
 <td>
   <asp:label id="lblDesc" runat="server" text="<%# Eval("propProdDesc") %>"></asp:label>
 </td>
 </tr>
 <tr>
 <td class="style5">
 <asp:label id="Label3" runat="server" text="Quantity:" font-italic="True">
 Font-Names="Times New Roman" Font-Size="Medium"></asp:label>
 </td>
 <td>
  <asp:label id="lblQty" runat="server" text="<%# Eval("propProdQty") %>"></asp:label>
 </td>
 </tr>
 <tr>
 <td class="style5">
 <asp:label id="Label4" runat="server" text="Colour:" font-italic="True">
 Font-Names="Times New Roman" Font-Size="Medium"></asp:label>
 </td>
 <td>
   <asp:label id="lblColor" runat="server" text="<%# Eval("propColour") %>"></asp:label>
 </td>
 </tr>
 <tr>
 <td class="style5">
  <asp:label id="Label5" runat="server" text="Def Design:" font-italic="True">
  Font-Names="Times New Roman" Font-Size="Medium"></asp:label>
  </td>
  <td>
   <asp:label id="lblDefDes" runat="server" text="<%# Eval("propDeflectionDesign") %>"></asp:label>
 </td>
 </tr></table>
 </itemtemplate>
</asp:templatefield>
</columns>
</asp:gridview>
<asp:objectdatasource id="GetJobSheetDATA" runat="server" selectmethod="GetJobSheet" typename="BusinessLogicLayer.QuoteProduct" xmlns:asp="#unknown">
  <selectparameters>
   <asp:controlparameter controlid="DDlQno" defaultvalue="129126" name="Qno" propertyname="SelectedValue" type="Int32" />
  </selectparameters>
  </asp:objectdatasource>

我想添加一个中继器，该中继器将在检索其自己的数据时使用"propProdId"和"DDlQno"作为参数

I want to add a repeater that will use "propProdId" and "DDlQno" as parameters in retrieving its own data
