ADO.Net前端页面调用后台方法使用

1、前台页面定义GetSource方法，传入列表显示字段；

cs 复制代码

<asp:Repeater ID="rptList" runat="server">
    <ItemTemplate>
        <tr class="lsi-t">
            <td>
                <%# Container.ItemIndex+1 %>
            </td>
            <td>
                  <%# GetSource(Eval("source").ToString())%>
             </td>
        </tr>
    </ItemTemplate>
</asp:Repeater>

2、后台页面定义Public公共类型的方法GetSource；

cs 复制代码

public string GetSource(string source)
{
    string sourcename = "";
    if(source=="1")//1 = 网页;
    {
        sourcename = "<img title=\"" + Resources.lang.WebPage+ "\" src=\"../img/wangye.png\" style=\"width:20px;height:22px;margin-top:2px;\" />";
    }
    if (source == "2")//2 = APP;
    {
        sourcename = "<img title=\"" + Resources.lang.APP + "\" src=\"../img/APP.png\" style=\"width:20px;height:22px;margin-top:2px;\" />";
    }
    if (source == "3")//3 = 微信小程序;
    {
        sourcename = "<img title=\"" + Resources.lang.WeChatMini + "\" src=\"../img/xiaochengxu.png\" style=\"width:20px;height:22px;margin-top:2px;\" />";
    }
    if (source == "4")//4 = 公众号;
    {
        sourcename = "<img title=\"" + Resources.lang.OfficialAccounts + "\" src=\"../img/gongzhonghao.png\" style=\"width:20px;height:22px;margin-top:2px;\" />";
    }
    if (source == "5")//5 = 对外接口;
    {
        sourcename = "<img title=\"" + Resources.lang.ExternalInterface + "\" src=\"../img/duiwaijiekou.png\" style=\"width:20px;height:22px;margin-top:4px;\" />";
    }
    return sourcename;
}

3、后台可以根据字段值判断列中需要显示的图标、数值；
