MVC :: Rendering Encoded Html?

Aug 13, 2010

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.

Html - Rendering Of .net Controls?

Mar 10, 2011

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.

MVC Html Helper Rendering?

Jan 20, 2010

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?

Web Forms :: Rendering HTML As An Image?

Aug 10, 2010

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.

C# - Rendering HTML Content From AJAX Result?

Jan 12, 2010

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.

MVC :: Rendering Blank Or Empty Lines In Html

Nov 21, 2009

I've been begining to learn asp.net mvc and noticed one of the first examples from wrox begining mvc is an unordered list, and it renders very clean compared to a list from listview in asp.net web forms. I notice that the is alot of blank or empty spaces in the rendered html.

I suppose that a blank html line is better than alot of additional code in the html lines (view state, server ids , etc) but sooner or later as the code approaches 100 lines than you could easily have a 300 line html souce code with 100 blank lines (if you had nothing but unordered lists).

Does anyone see that this is ok because mvc is still in version 1 (beta 2) or that a web browser will easily skip a line of blank html and it just a developer preference to see on blank lines in html code?Any feedback on MVC rendering blank lines in html for unordered lists with regards to SEO, web browser performance, html best practices, or just developer perference is welcome

MVC Rendering (RenderPartial, RenderAction) Html From Another MVC Application

Sep 9, 2010

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?

Add Correct Checked Attribute When Rendering Html

May 3, 2010

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?

HyperLink's NavigateUrl Changes After Rendering In To HTML Anchor

Nov 17, 2010

I have a Master.aspx and a Page1.aspx and Page2.aspx, all in the same directory.

Master:

<asp:HyperLink NavigateUrl="Page1.aspx" runat="server" Text="Page 1" />
<asp:HyperLink NavigateUrl="Page2.aspx" runat="server" Text="Page 2" />

both the Page1 and Page2 gets rendered from above master page.

all three are in a vertual directory which is mapped as a subdomain here are the details:

Virtual Drectory: dirvir
Domain: dirvir.example.com

now when I open any of the page say:

http://dirvir.example.com/Page1.aspx

the Hyperlinks are rendered containing

href="../virdir/Page1.aspx"
href="../virdir/Page2.aspx"

respectively.

On click of them it takes me to

http://dirvir.example.com/dirvir/Page1.aspx
http://dirvir.example.com/dirvir/Page2.aspx

where as I wanted it to be

http://dirvir.example.com/Page1.aspx
http://dirvir.example.com/Page2.aspx

I can achive the same by using <a> but i need them on the code behind too so thats not desired.

Note: using <a> with runat server also behaves in the same way HyperLink does.

Detect When All HTML Page Rendering Has Taken Place?

Jan 11, 2010

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?

Web Forms :: How To Redirect A Page After Running All VB Code And Then Rendering The HTML

Aug 31, 2009

I have an ASP.NET Form (aspx). It uses VB as the codebehind. I want ALL of the VB to run and then the page to render BEFORE redirecting to the specified form. The problem is, is that I have Response.Redirect calls in the middle of the VB code (aspx.vb) and it seems to redirect before rendering the page. Is there any way around this? I need to have the page render so that some JavaScript on the client side (aspx) can run (it is for Google Analytics).

HTML Partial Rendering Based On Multiple Dropdown Values?

Mar 29, 2010

I have a View that renders something like this:

"Item 1" and "Item 2" are <tr> elements from a table.

After the user change "Value 1" or "Value 2" I would like to call a Controller and put the result (some HTML snippet) in the div marked as "Result of...".

I have some vague notions of JQuery. I know how to bind to the onchange event of the Select element, and call the $.ajax() function, for example.

But I wonder if this can be achieved in a more efficient way in ASP.NET MVC2.

Web Forms :: Rendering Web Form To Html For Email And Keeping Styles Throws An Error

Mar 27, 2007

Basically I'm trying to output my web form to HTML so that I can send the result via email. I want to keep my styles so I have a user control called EmailTemplate which has the styles in it.

I keep getting an exception whenever I run the following code:

BasePage tempPage = new
BasePage();
Control ctl = tempPage.LoadControl("~/UserControls/EmailTemplate.ascx");
tempPage.Controls.Add(ctl);
PlaceHolder plh = (PlaceHolder)ctl.FindControl("plhEmailContent");
plh.Controls.Add(myForm);
StringBuilder sb =
new StringBuilder();
StringWriter sw =
new StringWriter(sb);
HtmlTextWriter htmlTW =
new HtmlTextWriter(sw);
tempPage.DesignerInitialize();
tempPage.RenderControl(htmlTW);
tempPage = null;
EmailHelper hlpr =
new EmailHelper(sb.ToString());
hlpr.SendEmail();

The exception occurs at tempPage.RenderControl(htmlTW); and says "Request is not available in this context".

Web Forms :: Rendering Page From Root To A Subdirectory Messes Up The Links On The Generated Html Page?.

Dec 28, 2009

I am having an understandable problem but have no solution for it.

Every time that a user updates their profile, I render the "ViewProfile.aspx?uid=userid" for an html file and save it in a subdirectory and thus all the links on the page get messed up and have wrong link because the links are relative in the code, ~\AppData2\userimages\userXX\profile\image1.jpeg
turns into

SubDirectory1\AppData2\userimages\userXX\profile\image1.jpeg which is wrong. meaning when I am in subdirectory, ~\ means the root of that subdirectory and therefore screws up all the link URLs defined on the page.

What is the solution to be able to render a page from root directory to a subdirectory and still have the links work?

Here is how I do it:(Partially)
protected void RenderPage()
{
try [code]....

Here is the problem ....

What is the best method to push large amount data(HTML Code) from c# into aspx web page?

PS: I used DIV innerHtml and also Literal Control but both are very slow if the size of the table increases.
