I have been working in a few MVC HTML Helpers. For example:
[Code]....
If account or url are null should I trhow an exception? Or render an empty string? Or render an Html comment in the view?
i'm using some components. When page render, components generate html comment tags. if i'm using this component 10 times on one page, html comments inserted 10 times.
How to remove html comment tag before render page?
The following dummy code in a view file works fine:
[Code]....
It simply displays "iFoo = 3". Commenting out the if block as following does not work:
[Code]....
What is the correct way to comment out a mixture of C# and html code in a view file?
I would like to be able to render a view in ASP.NET MVC so that all css classes in the elements are rendered inline in the tags. The sole purpose of this is to have email clients recognise html, as I believe that style must be inline for it to be recognised in email messages.
Is there any facility in ASP.NET MVC (or ASP.NET) that allows this?
way to write a comment at particular place in HTML from C#? For example, after a particular label? I can write a comment as follows:
protected void Page_Load(object sender, EventArgs e)
{
Response.Write("<!-- " + ... " -->");
}
but this appears before the DOCTYPE. I'd like to write it at a particular place, or at least in the "body".Thinking about it, I guess I could create a comment label at the beginning of the body and write it there:
Label1.Text = "<!-- " + ... " -->";
Is there a way to make sure it is in the body if I do not have a Label already defined for the purpose.
We have an ASP.NET 2.0 WebForms app that uses MS Ajax 1.0. It's working fine on all our environments (dev, test, IE6 VMs etc.). However, at the customer site the client side validation is not happening.We're currently trying to eliminate all the various factors and along the way we asked them to get their page source and send it to us, and we found something interesting.In our environment, our page has ASP.NET javascript in CDATA blocks:
<script type="text/javascript">
//<![CDATA[
. . .
//]]>
[code]....
This may be a red herring, but I'd like to eliminate it as the cause of the validation issues. whether specific configurations/patches/versions of ASP.NET will make it do this?
I have 3 servers where 1 of them serves as a load balancing server. In my ASPX page, I want to add a HTML comment to show the IP address or even host name of the server selected by the load balancer. I tried looking through IIS Server variables and tried using SERVER_NAME but that just returns the domain URL.
View 2 RepliesI am totally a new bee in asp.net mvc. Let me now explain my issue. I have a strongly typed view which inherits from a view model Document. I want to have a partial view in that view itself. My code for this purpose is :
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<HexsolveMVC.Models.Document>" %>
<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
DetailsDocumentTemplate
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<div>
<div>
<div>
2.4</div>
<div>
Published</div>
<h1>
Document Title: <span>
<%=Model.DocTitle %></span><span><a href="#">[ Edit ]</a></span></h1>
<ul>
<li>
<label>
<span>*</span>Created Date:</label>

I just upgraded my mvc 1.0 project to 2.0 using the wizard. My project builds fine however, my html helpers that I have used, does not render the input's ID tag. For some reason, only some controls render and some do not. For example:
[code]....
I thought it had to do with the fact that the value is empty, but from the two examples, they are nearly identical. Is this a bug? All was working before I upgraded.
I try to generate this HTML code with Razor:

Is it possible to render partial view as a model form in asp.net MVC?
View 5 RepliesI 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]....
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 ?
For some reason, i have to make a aspx page to let iphone/android to Post form. After the data processing of request.form , i have response a JSON string in plain text. However *.aspx will enforce to render html,head,body tag,so how can i disable it?
I cannot use ashx, because the mobile have to post image via form, as i search the answer by google ,ashx cannot handle the http post files.
Edit: As SLaks said, ashx can handle POST file using "context.Request.Files" and it works.
I have an application that renders HTML code to allow users to preview an email that the app sends out. The HTML is held in a string that is then put into the text property of a label. This is working fine, but now I need to also add XML to the HTML string for an email listener when the user clicks the Send button. The problem is that the XML tags are being ignored by the browser.
Here's the HTML string with the XML (at bottom):
MyHTMLString = @"
<HTML>
<head>
...
</head>
<Body>
...
<SomeXMLTag>TagContent</SomeXMLTag>
</Body>"
This string is then assigned to a label for previewing:
lblPreview.Text = MyHTMLString
But only "TagContent" appears and not the XML tags! Obviously, the HTML is ignoring tags it doesn't understand. How can I get the tags to also appear?
I'm trying to figure out if there's a good way to remove the duplication in this scenario. Here's the model ... a Person that contains two Addresses:
[Code]....
And here's the view:
[Code]....
The entire Address block is duplicated ... one for the Home address, one for the Work address. To remove duplication, I tried factoring out the Address block into a partial view, and doing this in place of the two divs above:
[Code]....
And the page renders fine, but when it gets posted back on form submit, the model binding doesn't work. (Of course it doesn't work ... the <input> tags for the address blocks both have name="Street", so there's no way for the model binder to know whether to shove that into HomeAddress or WorkAddress.)
I read this post:
[URL] but that answer seems most unsatisfactory. Is there a better solution?
I'm rendering a gridview from a controller by adding data logic. On the same page I would like to render another grid by binding it to anoither data source / linq query.
When I do it for one, I do the following

How do I render another data source to the same page ?? I havent done it before, and would like to know if it can be done and if so how!
I have a Partial View inside my Home view.
The Partial View submit a form calling an Action Method inside the HomeController.
It works fine with server validation, the problem is that after the post only the Partial View is rendered.
How can I render the entire Home view after post?
[code]....
At this time, after the post, the ascx shows the server validation erros but only the PartialView ascx code is rendered. The Url looks like this after the post:
[URL]
What I want is showing the entire Home view with the ascx inside showing server validation errors.
I got a problem that is I want to render some controls dynamically but I don't know how!
I want to add some controls like this inside of view:
<%ModalPopupExtender mpe = new ModalPopupExtender();%>
<%mpe.ID="m"+Model.Serial.ToString();
mpe.TargetControlID = "l" + Model.Serial.ToString();
mpe.PopupControlID = "div1";
mpe.BackgroundCssClass = "modalBackground";
mpe.DropShadow = true;
mpe.OkControlID = "OkButton;";
%>
This is ok but my question is How can I render this control?
I am trying to implement something like Ruby on Rail's ActionDispatch::Flash to pass messages to the next page request. The approach that I want to take is to store a pair of (partial view name, model object) in the session context and render it in the master page when rendering the request to display the flash message.
Inside my HttpApplication subclass I now have:
[Code]....
to render the partial view that was specified by name when Global#Flash was called.
I want to use a view for the flash message instead of saving the message as a string in the session context because I want to include the URL in the message:
<%-- BookmarkAddedFlash.ascx --%>
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<MyApp.Web.Models.Bookmark_AddModel>" %>
<%: Html.DisplayTextFor(m => m.Url) %> was successfully bookmarked.
And I only want to render the view when the subsequent request is made; i.e. one request sets the flash message and the subsequent request renders it.
I know that view model can be used for rendering a view, but if a page needs different models, how can I pass them to the view? And how do I use them?
