MVC :: Arbitrary Input Fields On Page

Oct 23, 2010

I am looking for some adivce about the possbility of doing the following while working whith MVC. Firstly sorry if the subject line is not very descriptive. I have put something together in ASP WebForms where by I can put a few core fields on my page that identify an object, e.g. a Name and ID... and then I can add arbritrary fields to the aspx page that are now saved and retrieved with the "owning object". These extra fields are stored in a seperate table on the database to the primary object fields. A short explanation of how this works:

1. I have my own version of TextBox (and other input controls) called r3d:TextBox (etc.) and this text box has XmlParent and XmlElement tags, this is done by way of an interface.

2. I have a r3dBase page that all my forms inherit from and this page check for the existstance of any r3d:TextBox (and other input controls) that have the XmlParen and XmlElement tag defiened.

3. When an iheriting form is saved the controls with the Xml tags defined are also saved, but I don't have to change any code in the code behind pages. The framework I have put in place takes care of this for me. The data is saved

4. When an inheriting page is loaded all controls with the XmlParent and XmlElement tags are populated with any data that has previously been saved for them that belong to the main object being displayed on the page.

This provides for a nice easy way for me to extend my forms with non core data when clients request new fields. It also means that different clients can request different new fields and I don't have to make any modifications to the core objects. I have another mechanism that determins what fields are seen by which clients.

Anyway I am completely new to MVC (not written a single line of code) so I have no idea as to whether this paradigm will lend itself to the above described mechanisms or not. Does any one have anythoughts about this, approaches I might try to achive the above to of functionality or perhaps completely different suggestions that would achive a similar end that might work well with MVC

Set The Inherits Attribute Of An ASPX Page Directive To A Class In An Arbitrary Assembly?

Feb 24, 2011

Is it possible to set the Inherits attribute of an ASPX Page directive to a class in an arbitrary assembly?

I need to modify an ASP.NET (1.1) application for which the source code was lost. In a new assembly (foo2.dll) I've created a replacement code-behind class that derives from the original class in the site's code-behind assembly (foo.dll). It seems easy enough to set the Inherits attribute of the Page directive to the new class name, but when I do that the web server gives me Could not load type 'Foo2.checkout2'. I am referencing the new assembly in the <assemblies> section of Web.config.

I don't see anything in the documentation to indicate that this scenario is unsupported, but I'm not certain that it is, either.

Original

<%@ Page Inherits="Foo.checkout" language="c#" Codebehind="checkout.aspx.cs" AutoEventWireup="false" %>

New

<%@ Page Inherits="Foo2.checkout2" CodeFile="checkout2.aspx.cs" CodeFileBaseClass="Foo.checkout" language="c#" Codebehind="checkout.aspx.cs" AutoEventWireup="false" %>

Hide Password Input Fields?

Aug 27, 2010

We have some error reporting code that, when an unhandled exception occurs, we send everything over in an email to our groups. This is great except if an unhandled exception occurs on a page with a password field then it's sent over as plain text.

Is there a way to iterate through Request.Form and figure out which item(s) are passwords? This is done at a low level so we can't look for specific controls.

Naturally, we could check to see what type the input box is but I'm not sure if that's the cleanest way. Advice?

The problem is after the user has entered all their data then then goto add stock and they are taken to a stock listing page, when they return to their form all the data the previously entered (name, department etc) has gone and they have to re enter it. How can I ensure that onces the user has entered this data, it stays there until the form is submitted or reset?

Set Background Color Of All Textboxes (input Fields) To Transparent?

Sep 22, 2010

I am upgrading part of a very old website. One of the pages that I own uses controls and dlls that I do not. There is one dll that puts a textbox (input field) on the page. This field is concepually a label but the person chose to use a textbox. Anyways, I can't change the dll.

Is there a way in my asp.net page that uses the dll to say all the textboxes on this page should have a transparent background?

This is the code I have access to. Any changes I make have to be made here.

C# - Adding Additional Input Fields Dynamically (similar To SO Careers)?

Similar to the "add more experience" functionality in [URL], I want to provide a "Add another location" link which should display an additional row of a set of 4 dropdowns (country, state, city, region). I'm actually using the CascadingDropDown jQuery Plugin for ASP.NET MVC [URL] for my location dropdown functionality, but I need to give the user the ability to add multiple locations. What would be the easiest way to handle this in ASP.NET MVC and jQuery?

Access :: Data Transfers / EU Can Make Selections And Input Text Into Fields?

Nov 11, 2010

I'm new to ASP but not programming in general. What I'm trying to accomplish is to have an ASP page where an EU can make some selections and input some text into fields and, upon clicking a submit button, have that input transferred to an access (.Mdb) database's table. I'm not sure how to go about this though. I don't know if it would be an SQL line or a dump to a different file type and then to Access (.Mdb) or something I don't know about.

MVC 3 Adding Arbitrary Text To The End Of An ActionLink?

Feb 14, 2011

I have a question about Html.ActionLink.

Imagine:

@Html.ActionLink(item.title, "Singlet", new { id = item.blog_id })
produces http://[url]/[controller]/Singlet/[id]

But what if I want to suffix some more arbitrary data at the end? For example:

http://[url]/[controller]/Singlet/[id]/#comments

To jump to the comments div. I know I can just make the string myself with something like:

@( new HtmlString(String.Format("<a href="Blog/Singlet/{0}/#comments">link to comments</a>", item.blog_id)) )

But I am hoping there is a cleaner way, perhaps with ActionLink?

How To Add IIS Virtual Directories And Arbitrary Files In TFS Solution

Feb 11, 2010

We have a web portal product from which we customize portals from customers. We use the precompiled web app and create a virtual directory (vd) where the customization resides. In addition to this we do some changes web.config in the web app folder. We would obviously like to keep these customizations under TFS source control.

When I try to add the precompiled web app (which I don't want to add to source control), a warning tells me that the vds cannot be added. If I only add the folder that is referenced to by the vd, I lose the references to assemblies in the precompiled web app.

My questions are:

How do I structure a solution for adding IIS (sub application level) virtual directories and still retain the references to assemblies? Is it possible to add other directories/files from the web application level (like App_Theme, web.config etc.) to the solution?

Since we already use Visual Source Safe, we have established a tree structure for each customization project:

Project Root
|
|-Custom Sql
|
|-Custom Portal Files (which is added as a virtual directory)
|
|-Other Customizations

I could probably do a lot of this manually through the source control explorer, but I'd like to have everything done through a solution.

I've followed the instructions using this article: [URL], but this doesn't address the exact problem that I have. Oh, and we are currently using Visual Source Safe for portal customizaton, but are eager to make the move to TFS.

C# - Manually Instantiate Controller Instance From Arbitrary URL?

Jan 14, 2010

My skills are failing me, and I know I've seen the code around for this but I can't find it. What's the quickest way to take any arbitrary URL, run it through your asp.net mvc routing system, and come out with a reference to a controller instance on the other end?For example, code execution is inside some arbitrary controller method. I want to do something like this:

...
string myURL = "[URL]";
RouteData fakeRouteData = new RouteData(Route???, IRouteHandler???)
RequestContext ctxt = new RequestContext(this.ControllerContext.HttpContext,
fakeRouteData);
ControllerFactory factory = ControllerBuilder.Current.GetControllerFactory();
Controller result = factory.CreateController(ctxt, controllername???)

I'm trying to get an instance of a controller just like the routing system does, regardless of where the code is executing. I'm unclear as to how to fit the pieces together at this point.

I ask, because I notice that the HtmlHelper BeginForm implements IDisposible.

C# - Adding Arbitrary Properties To A Strongly Typed List?

Jun 4, 2010

I'm looking for a good way to add arbitrary properties to the objects in a strongly typed list, based on the principle that I shouldn't pass a DataTable from my business layer to my presentation layer.For example, I might have a Category class with the properties CategoryId and Title. On one page I would like to fetch a list of all categories (ie. List<Category>) together with the most expensive product in each category.A while ago, I would have just returned a DataTable with some additional columns in it with the product data in, but I'm trying not to do that -- it would be trivial to set up it's not good practice. One option is to add a MostExpensiveProduct property to my Category class, but I might want to display the most recently added product in another case, or the cheapest product, so I'd end up adding a lot of properties to cover all the options. This just doesn't feel right to me.Am I missing a trick here? What is the best way of doing this? Or should I just be returning a DataTable to which I can add as many columns as I need and not worry about it?
