I have the following code:
Model:
[Code]....
Controller:
[Code]....
and the View:
[Code]....
The thing is that the HtmlContent string is getting "auto decoded" so the paragraph-elemnts gets renderd as <p>(sry might mix up decoding and encodeing..Im always getting confused by those)
anyway..I want the string to render as proper Html...how can this be achieved?
I would like to get the html code a view would generate in a string, modify it in my controller, then add it to my JsonResult.
I found code that would do what i'm talking about from a partial. I would like to do it from an aspx View though.
Extra explanation:
Let's say I have a page Frame.aspx that /Controller/Frame will return I would like to get my hand on the response before it out so I can to wrap it with jsonp. I do not wish to edit the return result in code every time, this is why I want to load the view programmatically.
/Controller/Frame currently returns Frame.aspx's content: <html><body>hello</body></html>
Let's say there's a function that renders a view in a string builder
StringBuilder sb = new StringBuilder();
RenderView(sb, "Frame");
now take sb and wrap it with jsonp:
[code]....
Let's say I have a string that I retrieve from a DB like: "Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et {{Hyperlink|navigateurl='/foo.aspx'}} dolore magna aliquyam."
This string may now get assigned to the Text-property of a label. What I want is to parse {{Hyperlink|navigateurl='/foo.aspx'}} and replace it with
<asp:HyperLink ID="IDLink" runat="server" Text="foo" NavigateUrl="/foo.aspx"/>
and assign the whole text including the HyperLink-Control to the Label.
Is that even possible? I think I could use reflection to create the control and set the properties. (the HyperLink-Control was just an example) But can I manage to insert the asp.net control back into the string to ensure the hyperlinks rendering as server contorl?
I hope you understand what I want. If not, feel free to post comments.
Edit1:
what do you mean by "assign the whole text including the HyperLink-Control to the Label."? can you xplain a bit, the reason for doing so ?
I think it won't work to assign the control into the string, because a asp.net control cannot be fit into a string.
After some thinking I found a way to achieve my goal. That would be to create a placeholder (I name it A). Therein some Literal control will be added. In addition I would create a placeholder (I name it B), add my Hyperlink into B, and add A into B. But I think is way to overkill.
The reason why I started thinking about this, was to gain access to Server.MapPath without replacing occurences in the string. I want to be able to use relative paths in my CMS, that get rendered like the NavigateUrl property from a hyperlink. Nevertheless I think my question with the dynamically creation is worth thinking about
Iam getting the below string in a variable"result" after xslt tranformation. if i do Page.ParseControl(result) iam able to render controls to the page. But the requirement is different. I have 4 place holders in that aspx page.I need to bind div id="Section1" to placeholder1, div id="Section2" to placeholder2 and similar the other two sections also to the corresponding place holder. how can i loop and add controls to corresponding place holder.
<div id="Section1" xmlns:asp="remove">
<asp:Label id="lblSection1" runat="server" text="section1" />
<asp:RequiredFieldValidator ErrorMessage="Mandatory Field-1" runat="server" ControlToValidate="txtNameSection1" />

I need to dynamically modify the contents of a column in a GridView1 before it is displayed. Basically, I need to convert every 'Environment.NewLine' in a field to a so it displays as a new line on an ASP.NET page. How do I do this?
View 2 RepliesI am trying to render a hyperlink to html. ( etc)
When the page loads it works fine. (and lots 10 links) on the update panel it hits the same function and tries to get another 10 links. I set the navigationURL to something like
"../Folder/Mypage.aspx?498592ghjgfosdfgo"
It is set identically both times(load and updatepanel postback) but when i try to render it to html the second time (on the update panel) it adds "../" to the front so i end up with
"../../Folder/Mypage.aspx?498592ghjgfosdfgo"
The function where it changes here
Public Shared Function RenderControl(ByVal c As Control) As String
Dim sw As New IO.StringWriter
Dim htmlw As New HtmlTextWriter(sw)
c.RenderControl(htmlw)
Return sw.ToString
End Function
c is the hyperlink which has the propertry navigationurl (this never gets changed) but the sw which ends up looking like this on load
<a id="lnkView" href="../Folder/mypage.aspx?AnTfh0ZsFP9NCxiBpM+Zd11cI+AUOF93HZQtumPgzMKky0PejGrda9I6kCFn070dOsIfq0M2AgI=">View</a>}
and this on panel update
<a id="lnkView" href="../../Folder/mypage.aspx?AnTfh0ZsFP9NCxiBpM+Zd11cI+AUOF93HZQtumPgzMKky0PejGrda9I6kCFn070dOsIfq0M2AgI=">View</a>}

Is there a way that I can create a page and master page and have some of the values dynamicly loaded thru selecting items in the querystring parameters.....
then is there a way that I can render that page only to a text string? by calling it with some querystring parameters and have it render to a string?
I guess my question is only the second part as I already know how to create a page with masterpage etc...
I also know how to create an email and snd it. I just dont know how to render the page to a string
I guess what I mean is that I want to render the page on the server in code behind and then have a text string which would be the rendered HTML in a string variable of some sort... I dont want to render the page to a users browser... in fact there would be no user at all connected (there is no need to be)What I want to do is (in a code module) load up a page created and stored in my wed app directory. I want to be able to load it from a code module and to bhe able to load it with some parametsrs and just get the rendered HTML.
I am trying to write a module which will send a HTML email to registered users and I want that HTML to be dynamicly created depending on some values in the recipient user,s profile.
i'm just new in ASP.Net.
I want to render a Web User Control (has many server controls inside of it) as a HTML string, is there anyway to do it?
I've got a page that I'm using as an e-mail template. I'd like to spin off a new thread, take the rendered page, and put it into an e-mail. Is this possible? If so, how? I haven't had luck so far.
View 3 RepliesI have some code that is used to replace certain page output with other text. The way I accomplish this is by setting the Response.Filter to a Stream, Flushing the Response, and then reading that Stream back into a string. From there I can manipulate the string and output the resulting code. You can see the basic code for this over at [URL] However, I noticed that Page Caching no longer works after the first Response.Flush call.
I put together a simple ASP.NET WebApp as an example. I have a Default.aspx with an @OutputCache set for 30 seconds. All this does is output DateTime.Now.ToLongTimeString(). I override Render. If I do a Response.Flush (even after the base.Render) the page does not get cached. This is regardless of any programmatic cacheability that I set. So it seems that Response.Flush completely undermines any page caching in use. Why is this?
extra credit: is there a way to accomplish what I want (render output to a string) that will not result in Page Cache getting bypassed?
ASPX Page:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="TestCacheVsFlush._Default" %>
<%@ OutputCache Duration="30" VaryByParam="none" %>
<%= DateTime.Now.ToLongTimeString() %>
Code-behind (Page is Cached):
protected override void Render(HtmlTextWriter writer)
{
base.Render(writer);
}
Code-behind (Page is not cached):
protected override void Render(HtmlTextWriter writer)
{
base.Render(writer);
Response.Flush();
}
Code-behind (Page still is not cached):
protected override void Render(HtmlTextWriter writer)
{
base.Render(writer);
Response.Cache.SetCacheability(HttpCacheability.Server);
Response.Cache.SetExpires(DateTime.Now.AddSeconds(30));
Response.Flush();
}
I am trying to use aspx pages as an email templates. There will likely be a bunch of objects on the page which will be used as replacements in the html. Because it's an aspx page I'll be able to use databinding, repeaters, etc. At run time, I want to be able to instantiate the aspx page from its path, pass in a bunch of properties, and then get the rendered result of the page and email it. This seems pretty straightforward from a asp.net website (maybe using BuildManager or Server.Execute.) However, I want to be able to use the same templates via a console application by just loading up a page object from its filepath. Is this possible?
View 1 RepliesI've been watching a video on Scott Hanselmnn teaching MVC 2 tricks/tips. He mentions how MVC 2 by default uses ASP.NET Web Forms view engine to render the output of the views; he mentions that the web forms view engine is a little slower than it could be for MVC 2 since it generates a control tree and then outputs the HTML to the page (I hope I said that right).
I was wondering what he meant by web forms generating a code tree before outputting the HTML to the page. Does anyone have insight on the view engine of Web forms and the steps of the rendering process works for ASP.NET and MVC2?
I would really like to disable the rendering for the form tag. Basically asp.net will be providing read only pages which should be very clean. i.e, no form tags required

Here is what I have in my .ASPX.CS code behind file and I cannot get the debugger to stop on the breakpoint on the .DataBind method:

using System.Web.UI.WebControls;
namespace zList

CategoryList.DataBind(); // breakpoint set here but debugger won't stop here
}
}

By the way, I fired up SQL Profiler and it appears the SQL select is not even being fired against
the server. As I said, the page is empty - just this junk when I scrape it via View Page Source:
