C# - Using The Same Code In Different (partial) Views
Jun 1, 2010
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 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 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 m working in asp.net and i want to implement partial views. i want to load .ascx page without refreshing the current page and not even url changed. can i implement it in asp.net.
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?
And the the partial view "Person" has an other model:[Code].... If I press the "Submit-Button" on the first view I get to the follwing controler: [Code]....
I have 2 partial views and models for them. I want to show both views on page and i assume i need one model to pass to the page. Do i have to create all the properties again for both partial views into one model?
I want to load the partial views when I click on the hyperlink, in my case I am loading both the partial views and then I am showing or hiding depending the parital views.
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.
Using the Razor engine how do I create Partial Views. Do I create a normal View and calling the PartialView() in the controller will only output the body content and when calling View() in the controller will output the full page with layout. If not, do I need to create specific Partial Views and then use RenderPartial in the View.
I am trying to get JQuery events to work with partial views in ASP.NET MVC. However, after you load a partial view through Ajax, JQuery seems not able to fire events for any of the elements in the partial view. I suspect that this issue will also happen if you are using other frameworks or JavaScript libraries to load partial html code with Ajax.
For instance, consider the following example:
Controller:
[Code]....
Once the page loads for the first time, you can click on the "Click here to display a Javascript message" and you will get a Javascript alert message that says "button clicked". However, once you click on the "Click here to load partial view", clicking on the button that is supposed to bring the Javascript alert message doesn't have any effect. It seems that the 'click' event is not being fired anymore.
why this issue occurs with JQuery and how to fix? This issue also occurs with other JQuery plugins that use events.
What is the best place for javascript that is specific to a partial view? For example, if I have a partial view (loaded via ajax call) with some divs and I want to turn those divs into an accordian, would it be better put the $("#section").accordion() in script tags inside of the partial view, or in a .js file in the function that retrieves that partial view and inserts it into the DOM?
Obviously, common methods I will be keeping in a .js file, however I am more talking about javascript very specific to the partial view itself. Most things I find on the net seem to say to put all javascript into a separate .js but nothing addresses the idea of partial views.
Scenario: Loading partial views into jquery tabs(Ajax Mode) using MVC3 &Razor . Works fine in FF but not in IE8 or IE7. I can trace the ajax request & responses in firebug fine and see partial views returned from the server (containing JqGrid Html Helper methods).This loads up fine within the tab conatiners in firefox.But in IE nothing happens and i cant see any ajax requests getting fired from changing tabs when i use Fiddler.Ive tried playing around with the ajaxOptions when i initialize jq Tabs to no avail.
Ive had this problem on MVC2 and i resorted to laying the tabs contents out statically ,which i dont want this time, as i need lazy loading. Below is a full page source dump from IE8, renedered using the razor view engine. (Links to all Csss and JS libs)
<script type="text/javascript"> $(document).ready(function () { $("#tabs").tabs(); }); </script> </head> <body> <h2>Index</h2> <div id="tabs"> <ul> <li><a href="/"><span>Home</span></a> </li> <li><a href="/ServicesMonitored/GetServicesMonitoredTab"><span>Monitored Services</span></a> </li> <li><a href="/ServicesMonitored/GetServicesFullTab"><span>Full Services</span></a></li> </ul> </div> </body> </html> From Controller: public class ServicesMonitoredController : Controller { IServicesMonitoredRepository<ServiceHeaderInfo,InfoDataItem> Services; public ServicesMonitoredController() { Services = new ServicesMonitoredRepository(); } public ActionResult GetServicesMonitoredTab() { return PartialView("ServicesMonitoredTab"); } public ActionResult GetServicesFullTab() { return PartialView("ServicesFullTab"); } #region Return Services [HttpPost] public JsonResult ReturnServices(string sidx, string sord, int page, int rows) { }
I am new to ASP.NET MVC, how to load partial page data again when calling different views?. I have divided my site.master page into two divs: Left Menu, and Right. When the first page load. Home/Index, it get the GetSourceList() from the Home Contoller and display the item as menu on left. The issue i'm having when I click on the item on the left, it display the data on the right but doesn't show the menu. I have a site.master reference in my list page.
I have a Controller set up for a certain View. This View contains 2 partial Views (ascx files). Each partial View has a Controller method that yields its DataModel. The containing View doesn't currently display any data, but just serves as a container for the 2 partial Views.
Here's the problem: The Index action of the containing View runs, but the Controller methods for the partial Views don't, so I get a null exception when the Model tries to render out the data that should be available. I'm using MVC 1.0, which is something of a bummer, since it seems that the next version is supposed to have something other than "RenderPartial" that will assist with this very issue. However, since I'm stuck for the moment with 1.0, can anyone give some advice on getting the Controller methods to run for the partial Views?
I am using PartialView(.ascx) to show a Popup on my .Aspx. Partail View is PopUp.ascx and i have written a Jquery fun where i call Action Mehod of PopUp. If i use 1 id in my Route then it works fine the PopUp dialog appears fine but if i include 2 ids in my route. Then it doesnt appears as a popup. Action Method of Partial View executes fine but the PopUp appears as a plain HTML in my dialog div.
I am nto sure what am I doing wrong here. I have a controller called Main and I have a action method called Navigation Bar inside it. i created a partial view from NavigationBar action method and called that partial view from my master page. when i call this partial view from a regular aspx page. i can see the menu, but when I call the same partial view from my master page, I don't see anything. below is my code
Controller Code
[Code]....
partial View code
[Code]....
and my master page code
[Code]....
I tried both renderView and renderPartial, they both don't work. However, if I out this staement on a regular aspx page and not the master page, it works.
I've recently began learning ASP.NET MVC.I created my first project, and added a model via Linq TO SQL. The first model handled a database table that held a list of menu items.I then created a view and the view would loop through all of the menu items returned by the controller and build a custom menu for me.
I then created a Model via Linq TO SQL to point to a table that hold's my site articles.I created a view that would itereate through all of the site articles returned by the controller and list them in the view.
Now I've taken the logic from the menu view and created a partial usercontrol view to build my menu. I've done the same thing with the SiteArticles.
How do I make the data from both of these modles availble in one view?I basically want to HTML.RenderPartial("MenuControl") in my master page and RenderPartial("ArticleControl") in the conent of the view.
I'm using the original view that i created to show articles..
So If i remove the rendering of the menucontrol user control from the master page and i call the view to show the articles, the articles will render because the controller knows to load the articles and return them to the view..
If i add the menu user control to the masterpage, I get an error because the view recieves data from the site article model/controller but not from the menu model/controller.
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.
