问题描述
我想添加一些额外的文本在现有的.aspx页面中运行。但没有找到任何合适的方式来做到这一点。

推荐答案
动态...
..aspx
dynamically... ..aspx
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="xx.ascx.cs" Inherits="xx.layouts.xxSublayout" %>
<%@ Register Assembly="System.Web" Namespace="System.Web.UI" TagPrefix="asp" %>
<asp:LiteralControl runat="server" ID="openingTag" />
<asp:PlaceHolder runat="server" id="contentPanel" />
<asp:LiteralControl runat="server" ID="closingTag" />
code behind..add与文本的div来比的Page_Load ...
code behind..add a div with text to some method other than PAGE_LOAD...
var inputWrapper = new HtmlGenericControl("div"){ID = "d1"};
inputWrapper.Attributes.Add("class", "yourcssclass");
inputWrapper.InnerText = "hghjggjg";
contentPanel.Controls.Add(inputWrapper);
要坚持标签回发...
to persist tag postback...
//add div ID to list, add list to session so it can be recreated on the page_INIT, this must be done or btn will NOT exist when "Get vCard" is clicked.
PostbackIDs.Add(inputWrapper.ID);
Session["pb"] = PostbackIDs;
在INIT ...
//Must recreate controls from session, so label is existing
if (Session["pb"] != null)
{
var pblist = (List<string>)Session["pb"];
foreach (var id in pblist)
{
// label
var inputWrapper= new HtmlGenericControl("div") { ID = id };
inputWrapper.Attributes.Add("class", "yourcssclass");
contentPanel.Controls.Add(inputWrapper);
}
}
由于init方法页面加载之前命中，控件的ID将到位文本添加到它。
Since the INIT method is hit before page load, the ID of the control will be in place to add text to it..
