Sitefinity (version 6.3.5) has a feature to allow users to subscribe to comments to be notified when there are new comments added via email. Is there anyway to do the same thing for blog posts themselves?
I am thinking similar to the functionality in WordPress to sign up to be notified when a new blog post is added to a blog. I've seen the RSS feed but looking for a way to allow the users to be notified via email.
It looks like this is possible, but not without some custom coding.

Create a .class file in your Sitefinity project solution then we must find out how to inherit one widget. For this example I will be inheriting Sitefinity login control.
To find the needed path that should be inherited (Telerik.Sitefinity.Web.UI.PublicControls.LoginControl) go to Administration->Settings->Advanced->Toolboxes->PageControls->Sections->Login->Tools->Login and find textbox: Control CLR Type or Virtual Path. In it you can take the path Telerik.Sitefinity.Web.UI.PublicControls.LoginControl as well as other properties that will not be needed from this example.
In the .class file created in step 1 inherit from Login Control.
Save the file and build Sitefinity project (if the project is website project build will not be needed).
Now register new widget that will be the modified login control.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace SitefinityWebApp.Custom
{
public class Class1 : Telerik.Sitefinity.Web.UI.PublicControls.LoginControl
{
protected override void LoginForm_Authenticate(object sender, System.Web.UI.WebControls.AuthenticateEventArgs e)
{
// Do Custom Stuff Here Before Base Call
// call base login class when done
base.LoginForm_Authenticate(sender, e);
// Do Custom Stuff Here After Base Call
}
}
}

We have a content page that runs a boolean check in our controller and we are moving that page to DNN. Is there a way to keep running that check using the Razor Host module?
I would basically show or hide button based on the status of a registration process.
My manager found the solution:
It turns out if you create a static file and save it in the Components folder (remember this is for DNN modules), you can just make a call to that class and its methods from within the Razor Host module as such:
#using MYNAMESPACE.Modules.Myproject.MyModule.Components
Some html
#{ var isRegistrationOpen = MyStaticClass.IsRegistrationOpen(); }
Registration Status: #isRegistrationOpen
I have some data specific to each razor view and and i do not want to hard-code it to each view. So, i want to add view related compile-time data to each view.
Custom attributes do not work for me because we cannot add custom attributes to razor views.
I do not want to re-fetch/populate this data from the data source(dictionary etc.) for each request or when view reached.
So, is there any way to attach data to each view at once throughout the life time of asp.net application?
Note
Actually i want to add scripts/styles generated by webpack for each view statically. Their links include hash values so they change when source scripts/styles change. So, i just want to get them added to each view only once(equivalent to typing them into view) through out the asp.net application, not every time a view loads.
I created a demo application for you here.
You will want to use your appsettings.json file, and inject your settings into your view.
In my appsettings.json I added a section called "ViewConfiguration":
"ViewConfiguration": {
"ExampleKey": "ExampleValue"
}
Your various values will need to go into your ViewConfiguration section.
For example where I have ExampleKey, you will use a generic name like "IndexPageStyleSheet", and where I have ExampleValue, you will need to update each release with the new stylesheet path. This will only need to be updated when the filename changes.
I then created a ViewConfiguration class which stores all of the values from the appsettings.json file.
You will need to create one property per configuration line, and ensure that the name of the property matches the name of the key in your appsettings.json.
For example where my appsettings.json has ExampleKey, my ViewConfiguration class also has an ExampleKey.
public class ViewConfiguration {
public string ExampleKey { get; set; }
}
In your Startup.cs you will need to tell your IOC container to load your configuration values into your configuration object.
In my Startup.cs, my ConfigureServices method loads my "ExampleValue" into ViewConfiguration.ExampleKey automatically.
public void ConfigureServices(IServiceCollection services) {
// This line is the magic that loads the values from appsettings.json into a ViewConfiguration object.
services.Configure<ViewConfiguration>(Configuration.GetSection("ViewConfiguration"));
services.AddMvc();
}
Now, in my _ViewImports.cshtml I inject my ViewConfiguration object so that I don't need to inject it into every single page. This can be anywhere in the _ViewImports.cshtml file. If you only want to inject specific configuration per folder, you can create a new _ViewImports.cshtml file per folder and inject different configuration objects into each one. It's flexible.
#using Microsoft.Extensions.Options;
#* Please rename this variable to something more appropriate to your application: *#
#inject IOptions<ViewConfiguration> InjectedViewConfig
Now, in any page, you can simply reference the property in your ViewConfiguration object.
For example in my Index.cshtml, I reference the ViewConfiguration.ExampleKey property by referencing the strongly typed property on InjectedViewConfig.Value, and it outputs "ExampleValue" on the page.
This value could just as easily be injected into a script or css link tag as the name of a file. It's very flexible.
<h1>Value: #InjectedViewConfig.Value.ExampleKey</h1>
With further research, you will be able to inject these values from any configuration source, such as Azure application settings or Azure Key Vault. Please see this article for more details.
If you are using mvc, you can create models and add it into the views. Since you don't want to recreate for each view, you can create readonly variables.
static readonly MyModel ModelData = new MyModel { PropName = "Hello" };
public IActionResult Index () => View(ModelData);
In your view you can now strongly type the value. If you are looking to use MVVM, you can refer to ViewModel concept still exists in ASP.NET MVC Core?
Implementing IFileProvider and IFileInfo provides changing the contents of view at compile-time. So, we could replace and provide static data in views with a template engine(i.e. http://dotliquidmarkup.org/).

I have one Windows Handheld device application which has the requirement of accessing a REST API. The REST API gives me JSON output which I am going to handle via Newton.JSON. Now to achieve modular structure I want to have the communication to the REST API be handled via a different module altogether something like a Class Library. But unfortunately it seems that it is not possible to do so via a class library(or maybe possible). So my question is what is the best alternative to do so?
Please note that I don't want to include those connectivity operations in my front end application project. And I am using .Net framework 3.5 & Windows Mobile SDK 6.0
Thanks in advance
Pseudo class library code:
public function void startQuery() //starts a thread that does the JSON query
//inside thread on query result use OnDone() delegate
private delegate void OnDone(string dateTimeString);
//In main GUI code add a reference to the class lib and init a new object then add an event handler to the OnDone delegate of the class lib
JSONClassLib myJson=new JSONClassLib();
...
myJson.OnDone+=new EventHandler(myEventHandler);
void myEventHandler(sender this, objext o){
//will be called when query is done
}
//you need to use Control.Invoke if you want to update the GUI from myEventHandler
//to start a query use something like this from your class lib
myJson.doQuery(string);
If you add your existing code we may help with creating a class lib and async code
Now I got my answer. Sorry I did a mistake while selecting the project type. I selected "Windows Form Class Library" project instead of "Smart Device Class Library" project. Now that I have selected the right one it is working fine for me.
BTW thanks for those responses.
Cheers
I'm doing an Windows Phone app where I have a WebApi running in Azure.
I'm using the new "Portable Class Library" (http://msdn.microsoft.com/en-us/library/gg597391.aspx) for my "Models" project which is of cause shared between my WebApi project (this is a normale ASp.NET MVC 4 project) and my Windows Phone project.
This works great and the model (POCO) classes are serialized and deserialized just as I want.
Now I want to start storing some of my Models/POCO objects and would like to use EF Code-first for that, but that's kind of a problem as I can't add the EntityFramework assembly to my "Portable Class Library" project, and really I would not like to either as I only need a small part (the attributes) in my Models project.
So, any suggestions to how a approach this the best way?
UPDATE:
Well, it seems like I can actually add the EntityFramework assembly to the project, but that doesn't really help me, as the attributes I need to use lives in System.ComponentModel.DataAnnotations which can't be used on Windows Phone.
Any suggestions still?
Don't use attributes. Use fluent API instead and create separate assembly for persistence (EF) which will reference your model assembly. Persistence assembly will be use used by your WebAPI layer.
I use a modified approach than Mikkel Hempel's, without the need to use pre processing directives.
Create a standard .NET class library, call it Models
Create a partial class representing what you want to be shared
public partial class Person
{
public int Id { get; set; }
public string Name { get; set; }
}
For non-portable code (like DataAnnotations), create another partial class and use Metadata
[MetadataTypeAttribute(typeof(Person.Metadata))]
public partial class Person
{
internal sealed class Metadata
{
private Metadata() { } // Metadata classes shouldn't be instantiated
// Add metadata attributes to perform validation
[Required]
[StringLength(60)]
public string Name;
}
}
Create a Portable Class Library, and add the class from step 2 "As Link"
When I need my domain-project across multiple platforms, I usually:
Create the standard .NET-class library project for the domain code
For each platform I create a platform specific class library
For each platform specific class library I add the files from the standard .NET-class library as links (Add existing files -> As link) and hence they're updated automatically when you edit either the linked file or the original file.
When I add a new file to the .NET-class library, I add it as links to the platform specific class libraries.
Platform specific attributes (i.e. Table and ForeignKey which is a part of the DataAnnotations-assembly) can be opted out using the pre-processor tags. Lets say I have a .NET-class library with a class and a Silverlight-project with the linked file, then I can include the .NET-specific attributes by doing:
#if !SILVERLIGHT
[Table("MyEntityFrameworkTable")]
#endif
public class MyCrossPlatformClass
{
// Blah blah blah
}
and only include the DataAnnotations-assembly in the .NET-class library.
I know it's more work than using the Portable Class Library, but you can't opt out attributes in a PCL like in the example above, since you're only allowed to reference shared assemblies (which again DataAnnotations is not).
I implemented the exception filter like here: http://www.asp.net/web-api/overview/web-api-routing-and-actions/exception-handling
And registered it globally, like microsoft or stackoverflow-users ( How to add global ASP.Net Web Api Filters? ) explained.
public static void RegisterWebApiFilters(System.Web.Http.Filters.GlobalFilterCollection filters)
{
//other filters
filters.Add(new MyExceptionFilter());
}
But if I throw an exception, my method is not called.
My exception-handling method is called only if I add the attribute [MyExceptionFilter] to the controller-method, but I hoped I can avoid that for all methods by registering the filter globally.
I tried to set a order for the filters, but this had no effect.
Edit: I have noticed, that in the new Wep Api RC the method is called "RegisterGlobalFilters" and this seems to be the MVC filter collection.
If I call
GlobalConfiguration.Configuration.Filters.Add(new MyExceptionFilter());
it works. This is the collection for the Web Api.
Looks like I have to build my own "FilterConfig" class for the web api...
Like I mentioned in my question: There are different filter collections. One for MVC and one for the web api.
If you want to add the filter to the web api, add this line of code to the global.asax
GlobalConfiguration.Configuration.Filters.Add(new MyExceptionFilter());
