I'm really new to MVC (just started a few weeks ago) and new to Ajax (never looked at it before today). I need some design / technical advice concerning Ajax, MVC, loading partial views, and posting / getting from a view. What I'd like to do it load a partial view that takes in a list of objects that have been queried from my db into an details-type view. The details view already has some other content that has been handeled and loaded from information pulled from my database and setup through some actions. It is strongly types to a model.
Below is the partial view I've created thus far:
And here's a portion of the Details page:
I'm not sure what to do for the Ajax.ActionLink. I'd like for a use to be able to type into the text box on it's left and hit "Add" (the Ajax link) and have the application add the content in the text box to the database. Should it be something else? An <input>? The Controller code piece is below:
So it should be adding the member into the repo / db and then reload the contents of the partialview. Instead, it's reloading the whole page and not just the partial view. (the url is changing from /project/details/5 to /project/membersection/).
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?
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?
I need to pass a list of Entity Objects from Controller to View but not put it in the Model context. It is the users homepage, but I am putting a list of alerts on the users home page(somewhat like facebook). So I need the User Context as the Model I pass but need to pass the Alert model as well so I can show the list of alerts.. How would I do that? The code below is what I have so far..
I have a form that I don't want to post back so I need to get the form values into my controller via jquery's ajax method.Here is my test controller method:
When I debug the controller method and look at the lineItems parameter, it always contains 0 items. I've tried various formats for the javascipt lineItems parameter but still 0 items. I'm also open to some other way of getting these values in like the jquery form serialze method or something else.
i can query to get my parent list and pass that into the partial view. Im running into problems when i try and make a recurisve call to the view. i cant figure out how to pass the second group back in.
have some Objects, lets say Employee and Role defined as below and I have defined relationships in my database that gives me a list of objects say employees and thanks to my framework each employee object also has a Role object linked via the RoleIDID, UserName, Password, Email, RoleIDRoleID, RoleNameSo in code I can do something like this
I know how to bind a simple objects to a dropdown list. However I am having problems binding my objects which contains sub objects to the control.i.e. with simple object i just do ddl.DataValueField = "myproperty" with my objects they contains sub objects which i want to bind. I have tried ddl.DataValueField = "sub-object.myproperty" which doesnt work.
I have a view which takes two objects: booking and list of reasons for canceling that booking.I have two classes: clsBooking, clsBookingCancelationReason I can read both objects in my view - no problems there. After I read the objects, I display the booking details and I generate a list of cancelation reasons in the following way:
The code above generates a list of cancelation reasons.How do I pick up the selected ReasonId from the list? I need to generate a link that will contain the bookingId and the selected reason for canceling the booking.I can get the bookingId out easily since it's stored in the Model...but how do I go about the selected ReasonId?
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?
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 partial view that has only a dropdown, i have called this partial view from a view. I can able to pass the model to this partial view and it renders successfully. However when some user selects a particular text from the dropdown, the corresponding value should be passed to view and it should be displayed in the label in view.
