MVC :: Extend The HtmlHelper By Using Metadata / Access Metadata In HtmlHelper Extension Method?
Jan 9, 2010I would like to extend the HtmlHelper by using metadata (similar to DataAnnotaions metadata). Specifically I want to be able to add a 'Title' attribute to html controls that will then appear as a tooltip on the control. I would like to keep the tooltip text with my model, for example by adding 'Tiltle' metadata to the model as follows:
[DisplayName("User Id")]
[Title("Enter your 10 digit user id")]
property UserId { get; set; }
So the questions are:
1. How do I add metadata (such as 'Title') to my model?
2. How do I access this metadata in my HtmlHelper extension method?

Setting Page Title From An HtmlHelper Class?
Sep 23, 2010I have an HTML Helper that essentially renders static content read from HTML files (inside of a vdir). There are cases when the HTML file has a title element defined and in such cases, the current page should use the given title. The content inside of the body should be rendered where the Helper class is referenced in the View.
This is how I call the helper.
<%=Html.StaticContent("staticcontent.htm",
new List<StaticContentTag>()
{
new StaticContentTag()
{TagKey=ReplaceTags.MarketName,
TagValue = "Austin"}
}, Model, true) %>
I'm passing in the ViewModel so that I can set the title and the last parameter is a flag that says whether to force the title or not.
The head has the title defined like this.
<title><%=Model.Title%></title>
I know what I'm doing wrong here by referencing the Model.Title element before even calling the helper. Any ideas on how I can work around this?

MVC :: Can't Use HtmlHelper In A Class That Extends ViewUserControl
Aug 24, 2010I'm trying to override all the Html.TextBoxFor etc. methods. I want to make them non-static methods in a class that extends ViewUserControl. But, according to intellisense, Html does have access to these methods; they simply don't appear. So basically I want to do something like:
[Code]....
But I'm not getting the syntax right.
Basically just trying to wrap the TextBoxFor call so that my ViewUserControl can drop in a unique id each time.

MVC :: 3 HtmlHelper.BeginForm - Return View?
Feb 11, 2011I am having some trouble with returning a View in response to an ActionResult method being invoked. In my view I have a ViewData which holds a value which is being read. Current process.. user selects 1 of three radio buttons, and clicks a button to apply the selection, which in turn triggers method which sets the form ..

Web Forms :: Create User Control Class That Extend Panel?
Aug 31, 2010I'm trying to create a user control class that extends Panel. Essentially, what I want to do is to have a panel that fires off an event whenever it's clicked upon.
So, I create something like this:
[Code]....
And then, in the ClickPanel.ascx.cs file:
[Code]....
I'm not exactly sure whether this would work as I haven't had the opportunity to test it yet.
The problem is that I can't have a class inherit from Panel. Creating a user control class requires that my class extend User Control - at least that's what the error messages have been saying up until now. The problem is that if I do extend it from the base class of UserControl then I lose all the functionality of the Panel itself and the entire thing is rendered pointless.

MVC :: HtmlHelper Extension Method V Partial View?
Jan 18, 2011I would like to know what the pros and cons are of creating an extension method v a partial view. From my understanding, htmlHelper extension methods are better as they enable one to unit test the view.
e.g. Assert.AreEqual(Html.Price(), "<td><tr><td>Price</td><td>4.50</td></tr>");
where the Price() method contains the presentation logic.
Since both the extension method and partial view are reusable, what then is the point / benefit of a partial view?

View 4 RepliesC# - How To Inherit A Page Class From A Class Library
Mar 16, 2011I might be asking a dumb question, but I have a client for whom I need to build many websites (10+) (asp.net 3.5) which will all the pages on each site will have the same codebehind, but the sites will launching in different regions and whilst following the same template, will have different content.I have built and launched site 1, and sites 2, 3 & 4 is nearly live, but it occurs to me that as all the sites are basically the same, the code is going to get more complicated to update as it will be duplicated, so if I need to do a bug fix on one site, I'll need to do the fix on all websites (and this is going to get complicated.)
I was wondering if it possible to somehow create a class library of all the current aspx.cs files, reference this dll in each website and then inherit these classes into the .aspx.cs files. So default.aspx in each site would still have a CodeFile of "Default.aspx.cs", but Default.aspx.cs would inherit the corresponing class from the dll:
using WebPagesClass;
public partial class _Default : WebPagesClass._Default
{ }
The reason for doing it like this is that if I need to change any code on a specific website (for minor changes in languages for instance), I can override the page functions and change the parts required. For all other pages which have not cha, I can just copy from a single website.Is this vaguely possible? If not anyone one got any killer suggestions of how to manage so many websites from a single codebase?
