tempdata variables works like a session variables?
basically i want to do is to when the form loads for the first time the variables should be empty. but the variable should be persisted until i am on that form.
the form contains searching with a submit button as well as the paging . basically my ques is to use what approach should i use?
What happens in Asp.Net MVC 2.0, when next request does not come ever to retrieve value from TempData. Is it stored permanently or expires?
View 1 Repliesi am using TempData to store the referrer for a website and via jquery i am issueing ajax calls to send emails ... I use tempdata to recover the original referrer URL.
It works great on the first read but then the second its empty.... I think this is by design... so i decided to try viewdata but this is stored but when read via the controller on an ajax call it is empty..
Does anyone know what my options are?
Here is the syntax of both lines
TempData["referrer"] = referrer; // WORKS great on first read and then is NULL
ViewData["referrer"] = referrer; // IS STORED but on first read is NULL
I have a method, which fill TempData:
[Code]....
so, I redirected to referrerUrl ([URL] then I even go to page: [URl] (Ideas method does not have any actions with TempData) and then go to [URL]
[Code]....
and it goes to selected by "GO TO HERE!!!" with value [URL]
So TempData works on my local machine in chrome, but not out on the server. It works fine in IE and firefox. I'm using the default Session State as InProc. I can see the cookie in chrome by looking at the developer tools.
View 4 RepliesI am working with ASP.net MVC 2 framework, for multiple sites. We have a base site and then sub sites that inherit from a "Core" site that contains 90% of the functionality that the sub sites will use.
In one of the controllers, I am saving some data, adding a UI message to the tempData and then using Response.Redirect.
The redirect works, but the tempdata is empty after the redirect.
I have tried returning "RedirectToAction" and "RedirectToRoute" with the same routing location and while it populates the TempData, the redirect doesn't happen lol..
So I guess in short, is there a way to get tempdata working when using a standard Response.Redirect?
I was under the impression that TempData was only persisted across one action but I am seem to be seeing the behaviour that it is persisted across one action only on the same controller.For example in a single controller if I do the following in my Event Controller,
TempData("test") = "Moo"
And then after displaying a view I then move to a new action (either by a GET or POST or redirect) I can read back the data,
TempData("test") = "Moo"
If I then move on to another action (either by a GET or POST or redirect) and check for TempData("test") I should get Nothing.However I have just tried this with two controllers and I get a very bizarre problem.For example on my first Controller, called Event Controller I set the TempData("test") = "Moo".I then move to an action on a second controller called Main Controller. I read back TempData("test") and find "Moo" as the result which is to be expected. I then perform some sort of task and a new GET, POST or Redirect request is made back to the Event Controller.
At this point I am expecting TempData("test") to be nothing, since I have already passed it to an action once already. However when I test this I am actually getting TempData("test") = "Moo" which I thought was not the expected behaviour, since in effect it would be like using Session("test) instead.
Some of my controller actions look for data in TempData. How can I insert data into TempData from my unit tests?
View 1 RepliesWe used MVC TempData to store smallish view state prior to redirects. This works worked great on our single Win2008 development server. Unforunately, the use of TempData no longer works in our load balanced production server farm. What steps are required to make MVC TempData durable across web servers?
View 4 RepliesThe WebFarm we are using doesn't supports Session. We are in a requirement to pass Data during redirects. How to do this without TempData dictionary since TempData uses Session inside.
View 2 RepliesI'm learning about storing state in 'TempData' when performing the PRG (Post-Redirect-Get) pattern. It says TempData stores session state on the server. I'm wondering if this is safe or unsafe in a load-balanced server farm?
Are there precautions to be taken with TempData? Or can we happily program against it with abandon. Just wanting to avoid the frights we all got with the Session back in the day with ASP.NET of old.
Working through Steven Sanderson's excellent Pro ASP.Net MVC Framework book.I am trying to reference the TempData collection to display a message after an item has been successfully updated and so have placed a reference to this on my Master Page.[Code]....
This is giving me the following compile time errors:
Error 1 The name 'TempData' does not exist in the current context <programme location>
Error 2 The name 'TempData' does not exist in the current context <programme location>
If I reference TempData on a content page it compiles (and works) fine.
I have a filter on my MVC web site. I display some records in a few different controller actions but when moving from one action to another I want to apply those filter values.
How can I persist values from controller to controller?
Should I use Session? TempData?
I am using Structure Map for IOC.
Maybe I could have a class that contains a Property for each Session Value that I use in my application and inject it on the controllers that need session?
<%#ViewData["id"] %>

I have a little MVC 3 challenge that I am trying to overcome.Here is my scenario:I have a controller called PersonController.cs with 5 methods:Add Add (post) Edit Edit (post) PopulateName(string EmailAddress) - POST
I have a viewdata class called PersonViewData.cs with 3 pieces of data:
Email FirstName LastName
I have 2 PageViews (Edit.aspx and Add.aspx)I have 1 PartialView (Details.ascx) - with 3 textboxes (Name, Email, Phone)I want to reuse this partial view in both the Edit.aspx and Add.aspx Views.
The user should NOT enter the First Name/Last Name - rather, once the user has entered the email address (OnChange of Email textbox), the First Name/ Last Name of person should be populated. This is done using the PopulateName(string EmailAddress) controller method. Meaning, I have an AJAX Form inside the partial view
Then once all 3 fields are populated. The user should be able to submit either the Add or Edit HtmlForm.
Code of Edit.aspx:
[Code]....
Code of Add.aspx:
[Code]....
The main issue is as follows:I have an AJAX Form inside the partial view. Since now we have a PageView Form and nested PartialView AjaxForm - Form within a Form - the Browser has a hard time with this concept. In fact, when a person enters an email address, the frmEdit/frmAdd gets submitted.
i need to show project information by value of dropdownlist.by using this code i get a list of data to drop down list.now how can i access the first data in ViewData(or record)
[Code]....
Does anyone have any idea why the code below doesn't give me any value but instead gives me "System.Web.Mvc.SelectListItem"? If I don't do a foreach but instead substitute the ViewData with this
<%= Html.DropDownList("PersonOnCallCheckBoxList") %>, I get the correct value.
foreach (var person in ViewData["Person"] as IEnumerable)
{
%>
<input type="checkbox" value="<%= person %>" /><%= person %><br />
<%
}
I'm new to .Net development, and now are following NerdDinner tutorial. Just wondering if any of you would be able to tell me What is the differences between ViewData and ViewModel(all I know is they are used to pass some form of data from controller to view) and perhaps tell me on what situation should I use ViewData instead of ViewModel and vice versa
View 1 RepliesI have one ActionResult method
[Code]....
This ActionResult is executed multiple time accoording the number user selected from previous page..each and every student id and StudentType is passed by that view to this ActionResult. my question is there any way that in ViewData we can store all these id's and studentType's so that I can use these id' and StudentType's in other ActionResult? bec I need only these two things in other ActionResult? I can implement this using cache but I dont want to do with that.
I have the following code in my post action method for Edit.
JobCardService.Update(viewData.JobCard);
var js = new JavaScriptSerializer();
ViewData["Notifications"] = js.Serialize(new {NoteificationType = "Success", Message = "The installtion was successfully updated"});
return RedirectToAction("Index");
However, on the client, ViewData is null/empty, i.e. this client code
var notifications = eval("<%= ViewData["Notifications"]%>");
renders as
var notifications = eval("");
I'm sure I'm doing something small wrong.
My doubt is i have two tables with Id as (Primary key) in one table and in the next table i have a Category Id field as Foreign key relationship with the 1st tabl Id field...
I have created a create view for the 1st table.My question is i have created a partial view for the 2nd table,but i need to pass the Id value to the second tables category Id field...So is there any way to do it by using Viewdata?

[Code]....
The functionality I'm looking for is really simple. I'd like to increment a an integer called
index. Each time I click a button, I post a form to an action method, which increment index and redisplay the view with the new value of the index.
So, I've 2 action methods called Increment (Get and Post versions ):
Increment (GET) action method displays the View, supplying also an initial value of index through the ViewData.
[Code]....
When I click to the button "increment" on the view, I post a form to Increment (POST). The value from the ViewData is sent back to the Controller through an "Hidden field" [Code].... Increment (POST) action method pulls the the value of the index, increments the value, and sends back the new value of index through ViewData when it re-displays the view.[Code]....
Unfortunately, all I can get is ONE increment. in the case above, I get 2. after that, I keep getting 2. If I change the value to 2, I get 3 and nothing else, etc... I suspect that ViewData, once it has gotten a value, keeps it forever.
I would like to know the limit of viewdata items.
I mean how many (no. of records) can be stored in one viewdata instance.
