            {
                code = " <td><asp:Image runat='server' Width='100' alt='Picture Not Found' Height='100' ID=ctl00_rptowner_ctl0" + (num + 1) + "_imgcat' ImageUrl='OwnerPictures/" + path + "' /></td>";
                code += "</tr>";
            }

        return code;
    }

hello

我想用，如果转发器中的条件

hello
I want to use if-else condition in repeater

<%# (Container.ItemIndex + 9) % 9 == 0 ? "<tr>" : string.Empty %>
               <td>
                <asp:Image runat="server" Width="100" Height="100" ID="imgcat" AlternateText="Picture Not Found" ImageUrl='<%# "OwnerPictures/" +  DataBinder.Eval(Container.DataItem, "imgSelf")%>' />
                </td>
           <%# (Container.ItemIndex + 9) % 9 == 8 ? "</tr>" : string.Empty %>

它将连续显示9张图片

现在在第二行/备用行中我想显示两个图像（左边1个，右边1个），中间有一个文本，所以我需要在转发器中使用if-else

任何人都可以帮助

如果项目在multitime中重复并且调用函数项重复为值

if item repeated in multitime and call function item repeated as the values

<asp:Repeater ID="Repeater5" runat="server" OnItemCommand="rpt_ItemsallerCommand">
                  <ItemTemplate

<％＃FunctionName（Convert.ToString（DataBinder.Eval（Container.DataItem，discPrice）））％>





in html

<%# FunctionName(Convert.ToString(DataBinder.Eval(Container.DataItem, "discPrice")))%>


in html

<script runat="server">

 protected  string FunctionName (string theValue) {
       if(theValue == "SAVED") {
     return "theValue";
        } else {
return "theValue"
       }
    }

</script>
