渲染控制，无需页面 [英] Render Control Without Page
问题描述
我目前正在与一个内部框架的工作。这一切都很大，但框架不使用aspx页面，它呈现使用的Response.Write页面。我遇到的问题是，我需要在页面上使用RAD的控制，因此，所有我需要做的是产生弧度控制，以获得HTML code，所以我可以转储到页面上。这可能吗？我试图创建一个Page对象得到它的工作，但它不工作。看来，当一个页面被调用时，它做一些其他的初始化。我也试过铸造HttpContext.Current.Handler到一个页面，而是因为他们使用的是其他类，而不是System.Web.UI.Page来处理请求，没有工作。
在这一点上，我也不太清楚什么尝试。如果我能MIMC页面创建类，那将是美好的。有谁知道确切的步骤正确创建和初始化一个Page对象？
希望这是有道理的......如果没有，我会尽量使其更容易理解。
谢谢！

只是想给你的code，我摆弄。希望这会告诉你什么是我想要做的：
这是工作：
的HtmlForm F =新的HtmlForm（）;
RadEditor重新=新RadEditor（）;
f.ID =form1的;
this.Page.Controls.Add（F）; re.ID =rdControl; StringBuilder的SB =新的StringBuilder（）;
StringWriter的TW =新的StringWriter（某人）;
HtmlTextWriter的HW =新的HtmlTextWriter（TW）; //页P =新的页面（）; //（页）HttpContext.Current.Handler; //的HtmlForm F =新的HtmlForm（）; //p.Controls.Add(f）; f.Controls.Add（重）;
这是行不通的：
的HtmlForm F =新的HtmlForm（）;
RadEditor重新=新RadEditor（）;
f.ID =form1的;
网页P =新的页面（）; p.Controls.Add（F）; re.ID =rdControl; StringBuilder的SB =新的StringBuilder（）;
StringWriter的TW =新的StringWriter（某人）;
HtmlTextWriter的HW =新的HtmlTextWriter（TW）; //页P =新的页面（）; //（页）HttpContext.Current.Handler; //的HtmlForm F =新的HtmlForm（）; //p.Controls.Add(f）; f.Controls.Add（重）;
最好我想获得第二个工作在一定程度上，所以我可以生成code。很抱歉的混乱。这是我的测试code。

所以，我想过这个问题，我想我知道那里的问题。控制正试图访问一堆未包含在DLL中的文件，如语言文件，样式，js文件等，我认为这个问题可能是，当我创建页面的新实例，它不知道其中，该页面是在参考的所有资源。有没有一种方法，我可以在页面设置为一个虚拟的网址是什么？现在我玩这个code：
HttpContext的背景下=新的HttpContext（新的Htt prequest（的String.Empty，HTTP：//本地主机：2090 / Default.aspx的的String.Empty），新的Htt presponse（NULL））;
在大量的研究，我设法找出我错过生成页面。显然，有一个功能，p.DesignerInitialize（），它初始化页面。一旦被调用，它生成的页面和控件可以呈现关闭它。下面是我用我的新功能：
公共字符串RenderRad（）
{
StringBuilder的SB =新的StringBuilder（）;
StringWriter的TW =新的StringWriter（某人）;
HtmlTextWriter的HW =新的HtmlTextWriter（TW）; 我的页面P =新我的页面（）;
p.DesignerInitialize（）; 的HtmlForm F =新的HtmlForm（）; p.Controls.Add（F）; f.Controls.Add（重）; re.RenderControl（HW）; 返回sb.ToString（）;
}
我也有一个类，从页面继承时将禁止检查所有控件是在形式：
公共部分类我的页面：System.Web.UI.Page
{
公共覆盖无效VerifyRenderingInServerForm（控制控制）
{ 返回;
}
}
I am currently working with an internal framework. It's all great, but the framework doesn't use aspx pages, it renders pages using Response.Write. The issue I am having is that I need to use a rad control on the page, so all I need to do is generate the rad control to get the HTML code so I can dump it onto the page. Is this possible? I've tried creating a Page object to get it working, but it doesn't work. It seems that when a page is called, it's doing some other initializing. I also tried casting the HttpContext.Current.Handler to a page, but that didn't work because they are using another class, not System.Web.UI.Page to handle requests.
At this point I'm not too sure what else to try. If I can mimc the Page creation class, that would be wonderful. Does anyone know the exact steps to create and initialize a Page object properly?
Hopefully this makes sense... if not, I'll try to make it more understandable.
Thanks!
Update
Just wanted to give you the code that I am playing with. Hopefully this will show you what I am trying to do:
this is working:
HtmlForm f = new HtmlForm();
RadEditor re = new RadEditor();
f.ID = "form1";
this.Page.Controls.Add(f);
re.ID = "rdControl";
StringBuilder sb = new StringBuilder();
StringWriter tw = new StringWriter(sb);
HtmlTextWriter hw = new HtmlTextWriter(tw);
//Page p = new Page();//(Page)HttpContext.Current.Handler;
//HtmlForm f = new HtmlForm();
//p.Controls.Add(f);
f.Controls.Add(re);
This is not working:
HtmlForm f = new HtmlForm();
RadEditor re = new RadEditor();
f.ID = "form1";
Page p = new Page();
p.Controls.Add(f);
re.ID = "rdControl";
StringBuilder sb = new StringBuilder();
StringWriter tw = new StringWriter(sb);
HtmlTextWriter hw = new HtmlTextWriter(tw);
//Page p = new Page();//(Page)HttpContext.Current.Handler;
//HtmlForm f = new HtmlForm();
//p.Controls.Add(f);
f.Controls.Add(re);
ideally I'd like to get the second one working to some degree so I can generate the code. Sorry about the mess. It was my test code.
Update
So I thought about it, and I think I know where the issue is. The control is trying to access a bunch of files that are not included within the dll, like language files, styles, js files, etc. I think the issue might be that when I create a new instance of Page, it doesn't know where that page is in reference to all the resources. Is there a way i can set the page to a "virtual" URL? Right now I am playing with this code:
HttpContext context = new HttpContext(new HttpRequest(string.Empty, "http://localhost:2090/default.aspx", string.Empty), new HttpResponse(null));
After lots of research, I managed to find out what I was missing to generate the page. Apparently there is a function, p.DesignerInitialize(), that initializes the page. Once this is called, it generates the page, and controls can be rendered off of it. Here is my new function that I am using:
public string RenderRad()
{
StringBuilder sb = new StringBuilder();
StringWriter tw = new StringWriter(sb);
HtmlTextWriter hw = new HtmlTextWriter(tw);
MyPage p = new MyPage();
p.DesignerInitialize();
HtmlForm f = new HtmlForm();
p.Controls.Add(f);
f.Controls.Add(re);
re.RenderControl(hw);
return sb.ToString();
}
I also have a class that inherits from Page that will disable the check for all controls to be in the form:
public partial class MyPage : System.Web.UI.Page
{
public override void VerifyRenderingInServerForm(Control control)
{
return;
}
}
这篇关于渲染控制，无需页面的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
