I need both show the cshtml page,and persist it to a file for next visit.
first I found Response.OutputStream, but it was unreadable.
then I found in asp.net we could override Page's Render method to achieve it,but I don't know in webmatrix how to do it.
and in MVC we could use ActionFilter, but I really don't find how to achieve it in webmatrix.
I know we can use the HTML helpers, but how about the strongly typed one's?
Html.LabelFor()
I have searched endlessly for an answer but found nothing useful! I'm writing a simple blog application using Web Matrix and its going pretty well, but I have run in to a problem. I am storing the content of each blog post in a ntext field in a table with the intention of entering HTML in to the database and then have my application pull it out and insert it in to a few different view pages. The problem is that all of the '<' and '>' characters are getting converted in to '<' and '>' when my application pulls the HTML from the database and displays it. I understand that this is for security (preventing code injection?), but only trusted users will ever be able to write posts using my application. Here is a screen shot of what gets displayed by my application:
Is there a way to disable this behaviour or work around it somehow?
I am working with a pretty complicated .aspx page that is full of controls (Telerik, Ajax, etc.) that all expand, collapse, show, hide, etc. when the page is loaded. Since this rendering happens on the client-side and can take different lengths of time based on the users machine specs, is there a way to detect when all (or some) rendering has taken place (jQuery?) so I can then act on specific elements, knowing they are fully rendered?
View 5 RepliesI want to make it so that by pressing a button on the homepage a user will be able to create a new html page on the server of the website (e.g. www.example.com/0002.html) I need this page to be always there and accessible by everyone. How can one create a html page programmably using asp.net?
View 5 RepliesI have an application I am trying to write that generates a text file conforming to a file specification, and the file could contain thousands of lines. This part is easy. The more challenging part for me is the user interface. It needs to be a web interface with various options to affect what data gets on the file; this part is no problem. The process for generating the file, though, could take a little time depending on the amount of data , and I would think the web page would time out.
What options do I have for the UI? Could I create some sort of service that the page calls and runs in the background? When the process errors or is finished, I'm thinking there could be an email sent out, or even messages displayed on the page.
can generate server control to html befor load page?
wanna replace HTML code to my content.
i need generate html code of server control .
I have sucessfully published a couple of WebMatrix sites withour a problem but this time I'm stumped. When I try to visit the new site all I get is a directory listing of my files and folders. The home page does not show.
View 4 Repliesdo you think it would be difficult to write a framework where mvc compares last html it output to the current html we want to output, and instead of sending the entire html, figure out what has changed and generate js code that will do the updating as compared to previous html? (presuming nothing was manually changed on the client using js).
View 2 Repliesi have genarated a xml file through the asp.net code as

how to generate HTML code from the code behind?
I would like to build a form that generate an html code inside a for loop.
I will let the user enter the photo name and No. of photos
Then I will generate an HTML code like this:
<a href="http://www.mzinj.org/images/gallery/Photo%20(1).jpg" target="_blank"> <img src="http://www.mzinj.org/images/gallery/Photo%20(1).jpg" alt="" width="345" height="247" /> </a> <br /> <a href="http://www.mzinj.org/images/gallery/Photo%20(2).jpg" target="_blank">
<img src="http://www.mzinj.org/images/gallery/Photo%20(2).jpg" alt="" width="345" height="247" /> </a> <br /> <a href="http://www.mzinj.org/images/gallery/Photo%20(3).jpg" target="_blank"> <img src="http://www.mzinj.org/images/gallery/Photo%20(3).jpg" alt=""
width="345" height="247" /> </a> <br />
depending on the No. of the photos the code will be duplicated in the loop
Then I will display the result of the loop in label or in a textarea to let the user copy it any where
The problem is that while compiling my code it considers the HTML code as a part of the behind file and gives errors on the single quote, the double quote and on the parentheses
this is my setup.I get some HTML from an OData service. When I try to HtmlDecode the HTML it won't! It simply outputs stuff like:
<p style="font-size:11px;"><br>
<br>
Vivek W. (ESB): No!......That's
Why can't I Decode this HTML and render it properly ?
I stored in a database a ntext "<b>Hello</b>";
But when I read it from the database I see <b>Hello</b> instead of Hello.
In the html source I see this: <b>Hello</b>]
I have the following line of code in an MVC2 project but I cant get it to render the HTML from the database, all I that is displayed is the HTML.
<%: (Model.Blog.BlogDetail)%>
I cannot seem to get over this problem. Im sure it is just a simple newbie question but I just cannot find the right answer on my own.
Im using MVC 2 and ASP. NET 4.0 to biuld simple CMS. Im storing encoded HTML in XML file which then i am passing to front page controller for display.
I understand that before inserting HTML from XML into the page, it should be decoded using HttpUtility.Decode() function.
[Code]....
I expected that this sould result in inserting decoded HTML into my index.aspx page. Then browser could render my decoded content for example in bold face.
What happens is quite awkward. In page source I have encoded HTML but it renders HTML with tags. For example I see "<strong> Lorem ipsum </stong>", instead of Lorem Ipsum.
I find it hard when using asp.net controls, to make proper css files because I don't know what the html output for the different controls end up as. For example, if I want to add a div tag using a asp.net control, it's not easy to know what kind of control I can use.
Are there any documentation that shows for each asp.net control, what the rendered html for that control will be? I understand that some controls will probably change it's output due to how it's configured, but most controls will at least follow a pattern here.
The best would of course be a service on the web where you can put in the asp.net control definition and get the rendered html out. Currently I have to put a control into my webform, run it and check the source in the browser, and if it's not the correct html tag, try another control and repeat. That get's tedious quite fast.
I was wondering if it's possible to render an Html Helper in a View inside a codeblock. So instead of:
[code]....
And have this render. Of course as it is, it wont render, so is there a way to programically decide if a textbox can be added without having to have a million delimiters in the page to accomplish this?
I am using HTML file control and HTML image control in .aspx page (for uploading image and showing on web page). It is working fine. But I am unable to get that uploaded image file path and file name in .aspx.cs page. And also tell me how to save selected image in MS ACCESS database.
I'm returning some preformtatted data from the server as a string. this is passed to the ajax results. For some reason the html is just displayed as a string rather than links etc.
this is what I want
<a href='#'>test</a>
this is what i get
<a href='#'>test</a>
This is my code
[code]....
What I am dealing with is a collection of data from 3rd party sites, some xml, some thumbnail images already.I essentially have an asp page that uses vb to collected the data and display it with some minor formating in a <div>, I use a literal control and a stringBuilder to put together the html and output it to the literal.
Here is my asp.net code
<form id="form1" runat="server">
<asp:Literal ID="Info_literal" runat="server"></asp:Literal>
</form>[code]...
So what I've been trying to do without any luck is have the output dump into a stream, then render the html into an image from that stream.I have looked at most of the links that have been posted in simular threads, and none of those are simular to exactly what I am looking for.
I'm trying to use the ListBox html helper in a simple form.
verhuurPrijzenLst is a simple list that gets put into the ListBox, I think I need "MultiSelectList", but I cannot use it (MVC framework needed)?
I don't know exactly how to do that ( bin folder and @inherits ? )
So it's nice to have a helper at hand, but if you cannot use it properly without using the MVC framework, that is a pity.

I am writing an application that renders a list of "Job" objects from an AJAX JSON response.
What is the best way to Render the markup from the returned data. Now I'm pretty convinced that its a bad idea to generate HTML markup on the server side and return that from the AJAX call. From experience it makes the HTML hard to maintain and re factoring the content is a nightmare, so I am returning a collection of Job objects as JSON.
The question, then, is how to render the HTML based on user input? I've seen some examples of having your markup template on the page then use JQuery to clone it and populate with the relevant data the insert it into the DOM.
The problem with this is that the template contains visible content (images and suchlike) and the application needs to degrade, so I have a repeater on the page that the severside code and populate on page load if JS is not available.
Objective:take string from "code-behind" writen in C# language and display it in html <p> element using ASP.NET MVC.
Code:
string xyz = "message1" + some line break character(s) + "message2";
ViewData["Messages"] = xyz;[code]..
I am working in an environment with many teams who are responsible for specific content on pages. Each team is sharing specific information (common class libraries, and master pages) that each are going deliver different types of content.Is it possible for an MVC application to do something similar to RenderPartial and pass a model to another MVC application Controller/Action to return content?
So the code for this might look like:
(http://www.mydomain.com/Home/Index)
<% Html.RenderAction("ads.mydomain.com", "Home", "Index", AdModel) %>
Maybe this is not a good idea as another thread has to spin up to server a partial view?
It doesn't seem that the Html.CheckBoxFor helper adds the correct "checked" attribute when rendering the HTML. I have a bool property rendered like so:
<%= Html.CheckBoxFor(m => m.Visible) %>
And the outputted HTML is this:
<input type="checkbox" value="true" name="Visible" id="Visible">
Is there some particular reason it does not add the "checked" attribute when the value is true?
