I am new to MVC coding, and currently try to migrate a legacy ASP.NET Web Form application into MVC. In Web Form I have several user controls, for example one control will be responsible to display a tree structure and user can select category from tree and do next step. In Web Form implemenation user control just raises the event to hosting web form, from there web form takes data to do whatever it needs to do.
While in MVC, I created correspodning partial view to display category data in a tree structure, I can display it, select node of tree without problem. But how can I let the hosting page/view know that some event is raisen from the partial view? What shall be the correct concept to handle this type of requirement?
There are different pages to reuse the same partial view, for example I may have following scenarios:
A category selection partial view in a user input page to trigger the input fields (quatity, date/time) to display and submit order. A category selection partial view in an admin page to trigger the display of invoice price, listing price and so on.
I have a master page with a partial view. I want the partial view to display only when viewing a specific page/action. Is there any conditional I can wrap around the partial view that checks for the page/action I'm viewing?
I am developing an application in asp.net mvc 2.0.In my view page i am rendering five partial views.While loading view page it very slow with partial views.if i remove the partial pages it loading very fast.How to improve the performace of partail pages while rendering.
What is the best way to build a progress page? In short, I want a user to complete a series of "setup steps" and hit a "Start" button. I would like them to be immediately redirected to a "Progress" page that will show them the progress of each step. In my case these would be: Shutdown device, copy file, Start device.
My approach so far is to build a Progress View page and use partial views. Here is what I have so far. I would like the Progress page to show up right away even if the ShutdownStatus View has not finished rendering. At some point, I plan on including a progress bar but right now I'm just curious as to how I can show the Progress page immediately then show each partial View as it completes.
I am trying to implement something like Ruby on Rail's ActionDispatch::Flash to pass messages to the next page request. The approach that I want to take is to store a pair of (partial view name, model object) in the session context and render it in the master page when rendering the request to display the flash message.
Inside my HttpApplication subclass I now have:
to render the partial view that was specified by name when Global#Flash was called.
I want to use a view for the flash message instead of saving the message as a string in the session context because I want to include the URL in the message:
<%-- BookmarkAddedFlash.ascx --%> <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<MyApp.Web.Models.Bookmark_AddModel>" %> <%: Html.DisplayTextFor(m => m.Url) %> was successfully bookmarked.
And I only want to render the view when the subsequent request is made; i.e. one request sets the flash message and the subsequent request renders it.
I have a list of items that loads when I call the page controller and I have an Ajax.BeginForm that calls the same (Index) Action. If the Action sees that it's an Ajax request (Request.IsAjaxRequest()) then it returns a partial view. I even have a div that contains a message about the results loading. That all works fine, but my results can sometimes take awhile and I'd like to hit the page first and then make the Ajax request so the user sees the page quickly and sees the "loading" message. I know I could click my filter button (triggering the ajax call) using jquery on document.ready, but is there a more MVC way to do this?
Members view (index) that lists members that users can select to show a partial view in the same view with details for the selected memberUses jquery (Ajax.ActionLink) to call a partial view method in the members controller to then load the members detail sectionWorks fine up to here....but I'd like to load the partial view with "member" details for a default or random member on initial load -- ie not through the Actionlink selectionHow do I invoke the partial view method on the initial load?
Let's say there is a textbox and a dropdownlist in mainview page, these two values are used by three partial views as well. when I use Html.RenderAction to post action to those three partial views, how to pass these two values to those partial views and in those views how to get these two values as a part of a object to send to database.
've created a Search partial view and it works, except for my view model. What i mean is, the partial view sends a string to my ActionResult Method, but only a string, that is not related to the view model that the partial view is built in. If i tell my ActionResult method to receive the view model in which the partial view is built in, it always tells me that i have null values. Here's my code This is my partial view:
Now here is my Model in my MoviesSearch view model:
I have added a jquery datepicker on my MVC view. This view has a partial view. I need to filter my partial view based on the datepicker's selected date. I need to show buttons on partial view based on the date.
I have added partial view like this:
div id="dvGames" class="cornerdate1"> % Html.RenderPartial("Partial3"); %> /div>
making my first steps with asp.net mvc and I actually create a (very) small website.I have 1 controller : TasksController1 view : Tasks/Index.aspx1 Partial View : Tasks/AvailableSorting.ascx In my controller I have 2 methods :
In my Tasks/Index.aspx, I add my partial view (<% Html.RenderPartial("AvaliableSorting"); %>)
That sounds simple. But, It just doesn't work : the Index return a list of Task and the parial view (should) return a list of string.The index.aspx works perfectly, but the partial view doesn't get the right model ! he gets the model of the Index page (list of Task).
"When a partial view is instantiated, it gets its own copy of the ViewDataDictionary object that is available to the parent view. The partial view therefore has access to the data of the parent view. However, if the partial view updates the data, those updates affect only the partial view's ViewData object. The parent view's data is not changed."Is there a common way around this? For instance I have a View containing two Partial Views (User Controls) that source the same data from the Parents ViewData. The first Partial View is able to update (add/delete) certain data from the Parents View Data, however the second Partial View sources the same data but obviously isn't reflecting the changes owing to the above MSDN statement.
I have a view that displays all the records of my Roles table. I want to be able to click a Role record and have a list of users that pertain to that role displayed to the right of the Roles list. I'm sure I need to use a view model for this so I can get two sets of models in one view, but I'm not sure how to set up the view model.
Repository (userRep) code:
I can just as easily get the full user list with return db.Users;
So what method needs added to my repository and how should my view model look?
