MVC :: How To Inject Auto-generated Code Into Views Via Partial Classes
Sep 16, 2010
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.

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 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,

Maybe this question is quite simple because I'm new to MVC2. I have a simple demo MVC project.
(1) A weak-typed view: Index.aspx
<% Html.RenderPartial("ArticalList", ViewData["AllArticals"] as List<Artical>); %>
(2) A strong-typed partial view: ArticalList.ascx
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<List<Artical>>" %>
<% foreach (Artical a in Model) { %>
<%= Html.ActionLink(a.Title, "About", new { id = a.ID })%><br />
<%} %>
(3) Here is the HomeController.cs
public ActionResult Index()
{
ViewData["AllArticals"] = Artical.GetArticals();
return View();
}
public ActionResult ArticalList()
{
return PartialView(Artical.GetArticals());
}
Sorry I'm using a Web-Form "angle", because if I'm using a Web-Form, when I visit Index.aspx, rendering ArticalList.ascx will call public ActionResult ArticalList(). But here I need to write Artical.GetArticals() twice in two actions. How can I put them in one?

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 have a "database explorer" page that is desgined to be pointed to an unknown database and allow users to browse the data, so it basically uses the SQL system tables to develop its queries and pull in data to tables using auto-generate columns.The problem that I have is that I would like certain types of columns to have certain formats and I'm wondering the best way to go about it. I could format the column in code in the RowDataBound event I assume, but I'm wondering if there some better standard way to do this? Is there a setting of any kind that I can use? For example I want all of the datetime fields to be formated for short date, like {0:d}, I want decimal fields to have 4 decimal places, etc.

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?

I have an MVC project setup, and I've brought the subsonic Active Record templates into my project, and they generated successfully and I can use the subsonic classes to access my database. However, how do I create a strongly typed view using the subsonic generated classes? When I select "add View" and I check the checkbox to create a strongly-typed view, none of the generated classes from subsonic for my data are available.

In one of my mvc application's view I have an AJAX form:
<% using (Ajax.BeginForm("HandleAddForm", "Home", new AjaxOptions { UpdateTargetId = "ContentDiv", InsertionMode = InsertionMode.Replace, OnBegin = "beginFormLoadEffect", OnSuccess = "successFormLoadEffect" }, new { id = "AddForm" }))
{ %>
...
<% } %>
When user lefts the computer after five minutes he is beign automatiacally logged out . And when I submit form by clicking submit button the ContentDiv is beign filled with full site with login panel. I.e. I want to show the full site with login panel NOT in the ContentDiv. Is there any way to avoid this behaviour?

Technically I have the Data Annoations working with Linq to SQL classes - the problem is when validation
passes. When UpdateModel() tries to do its thing i can an error:The model of type 'MyProject.Models.Employee' could not be updated.What i did was i created a partial class for Employee (that is generated by linq to sql), then stuck a Meta Data class on top of it for the validation
[Code]....
And in my master page i include
<script type="text/javascript" src="/Scripts/jquery.validate.min.js"></script>

Is there any way to avoid having unwanted fields generated into MVC views by the default VS wizard? It would be nice if a ScaffoldColumn=false annotation could achieve this, but it doesn't.
Of course I have a mile long wish-list regarding generated views, e.g. I would prefer EditorFor as a default for all generated fields. I suppose this is T4 and T$MVC territory only, or are there other tools?

I am wondering if Java Spring MVC has some sort of implementation that relates to returning partial views like ASP.NET MVC? Basically I want to return HTML, that is bound to an object and return it to a javascript callback to append to the dom, stead of building the html with Jquery (which is tedious). If not I may go with Jquery templates.

I want a view that contains 2 partialviews. 1 partial view should be a create or edit view (of items) and in the second partial view there should be a list with the items that are created (and which can be edited). When an item in the list is selected for editing the 1st partial view should show the edit view with the item to be edited.
After saving the data, the create view should be shown in the 1st partial view again. When the view comes up for the first time the 1st partialview should contain the create view. In normal ASP.net I would do this with a formview (with insert and edit mode based on the itemselected in the gridview) and a gridview (and of course everything in an AJAX update panel).

I've got a section of code that is common to a whole load of pages, so it makes sense to put it in a partial view. However, part of it's function is declaring and assigning a set of variable that will be used throughout the main page. However, if I move that code off to a partial view and use renderpartial to include it, I get a compiler error saying the variable isn't defined - "The name '<variable name>' does not exist in the current context". Am I missing something basic/silly?

I have an "Instruction" view, which have partial views for entering instruction details, different attributes for the instruction, different input values etc for the instruction. Each of which is seperate partial view. The main view have a save button which save all these details. "InstructionDetails" partial view have instruction name, description and its model is "Instruction". "Attribute" partial view have dropdown to select attribute and a textbox to enter its value. It also has an button "Add to list" which is intended to add attribute details to a table which is in the same partial view for attribute, its model is "Attribute". Same is the senario with input values. I have few problems where i am struck up with.When the "Add to list" is clicked in Attribute partial view, the values from the dropdown and textbx need to be listed to the table.When "Save" button is clicked the entire view need to be saved.
