I found datetimepicker class in one project . i.e C# project , in this project he/she created one class named as datetimeextensions.cs.
so then he/she imported in to one view and used like this .
[Code]....
i added this class in to my project and i tried to import but it doesn't appear in extensions?
Why are Razor views not generated as partial classes? Making them partial classes gives us the option to have a code behind where we can do some of the stuff we're forced to do in the template itself in the code behind file.
Yes, I know the standard "go-to" thing is Html helper but I don't want to use Html helpers for these things as they are too specific to the view in question and besides, having a clutter of extension methods is just not the way to go.
I'd like to see Razor views generated as partial classes.
I have written a t4 template that basically replaces the work done by StronglyTypedResourceBuilder to give design time access to string resources as properties of classes, one class per resource file. Why? Well I needed to add some customer code that handles string token substitution and a few other customizations. Anyway, the template is working out really well and I may blog on it soon.
In the mean time though, following a common pattern, I have one .resx file for each view, master page, controller, etc. I would really like my t4 template to add a property to each such entity that gives quick access the custom resource class associated with it. For controllers this is easy. T4MVC is ensuring that they are a all declared partial. All I need to do is create the appropriate partial class in my output that declares a readonly property that returns an instance of the appropriate generated resource class.
The Problem:
I would like to do the same thing, inject generated code, into my views. Were this traditional ASP.Net, each .aspx page would have a .aspx.cs page and possibly an .aspx.designer.cs page that are all partial classes extending in the aspx page's class definition. There is no such thing by default in MVC and for good reason. However, I think for my purposes, if there is a way to do this, it would be the way to go.
I could subclass ViewPage and add a generic type parameter and a property that returns the class of that type but that has certain complications. I think adding auto generated code to each view via partial class (that is what partials are for after all) is the way to go.
I have made a basic attempt. I have created a .aspx.cs file for a view and placed a code behind attribute in the page declaration but the class generated from the view seems to reside in a different assembly any my "partial class" ends up as its own class in the same assembly as all my other code.
I am new to LINQ. when we drag tables we get a dbml file and designer file.
For example DataClasses1.dbml and DataClasses1.designer.cs.
Once we have them then we can start using our LINQ Queries.
In my company project I do not see this designer files and instead there are .tt files which were used as templates to greate ABC.generated.cs files. Is this same as designer class?
I am following the Nerd Dinner tutorial as I'm learning ASP.NET MVC, and I am currently on Step 3: Building the Model. One part of this section discusses how to integrate validation and business rule logic with the model classes. All this makes perfect sense. However, in the case of this source code, the author only validates one class: Dinner.
What I am wondering is, say I have multiple classes that need validation (Dinner, Guest, etc). It doesn't seem smart to me to repeatedly write these two methods in the partial class:
[code]....
This doesn't "feel" right, but I wanted to check with SO to get opinions of individuals smarter than me on this. I also tested it out, and it seems that the partial keyword on the OnValidate method is causing problems (understandably so). This doesn't seem possible to fix (but I could very well be wrong).
I don't know if this has to do with how FindControl works or how scope works. But my base class is having a hard time seeing the fields of child classes. Currently I'm planning have the derived class set a property in the base class, but there are a lot of derived classes, so that isn't a very attractive solution.

View 15 RepliesI'm curious as to what people consider better practice, between duplicating model structure in the view model and using a mapping tool to move data between the two, or aggregate the model inside the view model, i.e. have a property on the view model class that is a reference to the actual model. Which is considered a better approach in general?
View 1 RepliesI have an MVC view that contains a number of partial views. These partial views are populated using partial requests so the controller for the view itself doesn't pass any data to them. Is it possible to reload the data in one of those partial views if an action was triggered in another? For example, one partial view has a jqGrid and I want to refresh the data in another partial view when a user selects a new row in this grid. Is there a code example for this scenario (in C#) that I can look at to see what am I doing wrong? I am using ajax calls to trigger a new request but non of the partial views are refreshed so I am not sure if the issue is with the routing, the controller,

I have done partial views in ASP.NET MVC but now I want to convert it to ASP.NET. I have used AJAX and JavaScript. How can I convert the following:
<a href="#" onclick="LoadPartialView('#MainContentDiv', '<%=Url.Action("AdminHome", "Admin")%>')">Home</a> ,
<input type="button" value="Submit" onclick="LoadPartialViewPost('#MainContentDiv', '<%=Url.Action("ViewPage", "Controller")%>', $('form').serialize())" />
to ASP.NET, or in other words, how can I load a partial view in ASP.NET?

How do you change the URL of views for example if I have the following:
/Views/Home/Details.aspx will produce the following URL: /Home/Details/1
I would like to rename it to say News. I remember it being something along the lines of ActionResult but can't remember exactly.
1) I'd like to make use of the built in membership system. Easy enough by itself. However, I wonder if I should still be building an entity around the User and Role classes since they aren't part of the custom database. As such, they aren't part of the domain's aggregate chains either.2) My entities contain the better part of my business logic. For example, my Category entity has the following method: AddForum(User user, Forum forum). All logic tests are performed there and applied, or not, to the private forums collection. What I am wondering about here is the appriateness of service classes. In the traditional mvc style, a service class operates between the controller and repository to perform business logic. With domain design, we do it in the entities. Should I still be using these, now superfluous service classes? Or should I save them for when something is really needed that isn't part of the domain itself, such as an EmailService

I want to instantiate an object where its class is declared in a separate file and is part of a separate namespace.

Do you think it is possible to bypass VisualStudio and code all the projects by hand? I believe this is quite possible with pure C# code but what about the problem I've described above? Can somebody please write the minimum directive(s) to include an external class or file. (I know about VS 'Add class...', etc. )
In ASP.NET I have a form that has a Textbox named txtOutput and a button. In the main file.aspx.vb I can call a function from the button handler and in that function I can have
txtOutput.Text = "Some Message"
with no problem. I have a bunch of functions in several other classes. For instance I have a class named AbleCommerce that does some database functions. These functions are called from my main class. In those functions, however, I have no visibility of txtOutput. All of my classes are, unfortunately, in the default namespace which I understand is not optimal but didn't seem to impact this issue.
I know this is an easy one I've just not understood properly but it has me stumped. My gut says that I probably need to pass the Textbox object to my "other class" but can't for the life of me figure how.

I feel like the class design works well for modeling the data and our business rules, but it does create a few limitations like the above situation. I liked the separation of the PolicyTerm and Billing for the ability to allow that code to be modified and tested independently. Also, I feel like it keeps each section smaller and simpler.

View 4 RepliesI am changing my ASP.NET app to use a web farm. To do this, I need to change the session state from in-proc to a State Server. To do this, it is my understanding that the classes that are used must be marked as serializable. How can you tell if that is possible with a class? Will you get an error at compile time if it is not possible?
