View 2 RepliesInjecting A Web User Control With Ninject In WebForms
Dec 16, 2010I have an aspx page that I would like to have injected a reference to a user control. The user control is stored in a seperate assembly and loaded at runtime. After injected the user control it should then be loaded into the control collection of the page.
Everything seems to be working fine expect the point of adding the control to the page. There is no error but the UI for the control doesn't show.
global.asax.cs
protected override Ninject.IKernel CreateKernel()
{
var modules = new INinjectModule[] { new MyDefaultModule() };
var kernel = new StandardKernel(modules);
// Loads the module from an assembly in the Bin
kernel.Load("ExternalAssembly.dll");
return kernel;
}
and here is how the external module is defined in the other assembly:
public class ExternalModule : NinjectModule
{
public ExternalModule() { }
public override void Load()
{
Bind<IView>().To<controls_MyCustomUserControlView>();
}
}
The debugger shows that when the app is run, the Load on the external module is being called, and the dependency gets injected into the page.
public partial class admin_MainPage : PageBase
{
[Inject]
public IView Views { get; set; }
At this point when trying to add the view (here a user control) to the page, nothing is shown. Is this something to do with the way the user control is created by Ninject? The loaded control seems to have an empty control collection.
inside aspx page
var c = (UserControl)Views;
// this won't show anything. even the Control collection of the loaded control (c.Controls) is empty
var view = MultiView1.GetActiveView().Controls.Add(c);
// but this works fine
MultiView1.GetActiveView().Controls.Add(new Label() { Text = "Nice view you got here..." });
and finally the view/user control:
public partial class controls_MyCustomUserControlView : UserControl, IView
{
}
It contains just one label:
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="MyCustomUserControlView.ascx.cs" Inherits="controls_MyCustomUserControlView" %>
<asp:Label Text="Wow, what a view!" runat="server" />
Can The Repository Pattern Work Well With Webforms
Mar 8, 2011I've been using MVC for the last year and unfortunately I am stuck adding features to an existing web forms site. The site makes heavy use of inline SQL and it is kind of all over the place. Using an ORM is not going to happen either and wouldn't address the problem of keeping queries all in one place.
Can the Repository Pattern and Service layers also work well with classic asp.net web forms?

HTML Codes In Strongly Typed HTML Helpers
Jan 20, 2011So, I am having a hard time getting this to work. I am trying to add some typographic HTML codes to some labels I have strongly typed to my model.
<%: Html.LabelFor(m => m.Name) %>
I am using data annotations to customize the DisplayName of the property:
[DisplayName("Your friend’s name")]
public string Name { get; set; }
However the actual code is being displayed for the label:
Your friend’s name
I have also tried just using the old write method:
<%= Html.LabelFor(m => m.Name) %>

View 2 RepliesWeb Forms :: Is Possible To Use The Mvc HTML Helpers
Jan 14, 2010I have been using web forms and I have been let down by them. I hate the way it mangles my element id's and names. I want to have full control over my html and have the ability to have multiple forms on one page.
I do not use view state or post backs. All my server communication is done using JQuery ajax and sometimes page methods.
My pages do not make use of any runat=server controls other than occasionally using the repeater.
For now I have been using inline code like the following but I like the mvc html helpers.
EXAMPLE:
[Code]....
At the moment, using the asp.net mvc framework is not an option but I would like to use the HTML helpers in my asp.net application.
Is this possible to use the mvc html helpers or do I have to create my ow helpers?
MVC :: HTML Helpers Does Not Render ID?
Mar 19, 2010I 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.
MVC :: HTML Helpers - Passing Id And Name To Views?
Feb 21, 2011I´m learning mvc and I found a problem. I have a product table that stores currencies in integers. On the other hand I have a table name currency that stores each int id with the currency name.
On html.dropdownlist I followed the pattern:
The name of the form field (ArtistId) The list of values for the dropdown, passed as a SelectList The Data Value field which should be posted back with the form The Data Text field which should be displayed in the dropdown list The Selected Value which is used to set the dropdown list value when the form is displayed
This was great for Forms in order to display selections. Right know I´m finishing my details views and I need to use the int id on product table but display the name on currency table associated to that int id.
Does anyone knows if it exist an html helper that renders the Data Text Field that should be dsiplayed on the View taking into consideration the int number?
Something like @html.display("Name", model.product.currencyid) where name is pulled from db.currency?.

MVC :: Razor: Referencing Declarative Html Helpers?
Dec 15, 2010I'm trying to write a simple declarative html helper: [Code]....
The helper works fine if I embed it into the page I want to use it on. But if I move it to a separate .cshtml file and place that file in the ~/Views/Helpers directory, my view can't be compiled anymore because the helper is not found.According to Scott Gu's blog article on Razor it should work.
The only workaround I have found so far is placing the Html helper in App_Code and Referencing it as @[MYHTMLHELPERFILENAME].Echo(...) . This works but is a bit messy since I don't want to repeat the name of my extension method (Echo.Echo("inputstring"), nor do I want to put all of my html helpers into one single file (something like MyHtmlHelpers.cshtml).It certainly isn't what Scott announced either, so I guess I must be doing something wrong.

View 3 RepliesMVC :: Html Helpers / User Controls Dependency Injection?
May 12, 2010I've just started wokring with Asp.Net mvc and i relay love it. One thing I don't know how to do it yet is:
If I want to develope a new user control (e. g. PeoplePicker) how I get the data? I don't want to use allways ajax requests, some controls should be initialized when the page is loaded. So I could use the Html Helpers and create own extension. So far this is exactly what i want and it's working. But now to the real problem. I can't use dependency injection in extension methods (I'm using spring.net, but the problem should be in all di frameworks).
So which approche is the most common to use this problem? Must I realy pass in the data from my controller? But then the controller must know how my user controls works, I don't want that!
