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?
I have an several controllers where I want every ActionResult to return the same viewdata. In this case, I know I will always need basic product and employee information.
Right now I've been doing something like this:
[code]....
This is just pseudo-code so forgive any obvious errors, is there a better way to be doing this? I thought of having my controller inherit a class that pretty much does the same thing you see here, but I didn't see any great advantages to that. It feels like what I'm doing is wrong and unmaintable, what's the best way to go about this?

If you have a global navigation tree, Countries --> States --> Cities for example, how do you correctly implement this in MVC2? In my example, the view model for States does not contain Countries and the tree would break as it needs the Countries list to build the tree. It sounds like this should be easy, but it doesn't sound right to include the entire model for a single State or City view.

View 15 RepliesI know there is a couple answered questions on here regarding "request scoped" globals, but I want to nit-pick on something specifically and maybe squeeze some extra enlightenment out of one or two of you.I have an ASP.NET C# Website and a static Dictionary of objects (loaded from DB once on Application start). Each page request will need to do a lookup in the Dictionary (based on a key derived from the request url/etc) and get the appropriate object.The issue is I'm trying to maximize efficiency by reducing the lookups to the Dictionary per Request. Doing just a single lookup within a Page itself is easy enough and I can pass the object to sub controls, etc too.. but global.asax is separate from the Page and it also needs to use the object (in Application_BeginRequest and Session_Start).
So is doing a Dictionary lookup once in Application_BeginRequest, once (when necessary) in Session_Start and once in the Page negligible speed wise, even if there are many requests coming in every second?I would like it if I could just have a Request scoped global variable that I can easily call upon.. the only one I see available though is HttpContext.Current.Items and that is a Dictionary itself.Am I beingridiculously nit-picky with my concern over efficiency? or will these milliseconds (nanoseconds?) get me in the long run when more and more requests are being made?
PS. I currently only have around 100 objects in the Dictionary although this may increase in the future.
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 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.
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?

View 16 Repliesi return data to view by viewdata. and allways checking the viewdata for null but the viewdata is defiant null
this is my code for return data from database
[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.
I am new to MVC3 razor and facing one issue as described below. I have one strongly typed view to display list of items and user can edit the view. When user click on a print button a popup should open to print the list . So I have to pass the current view to the popup page.
We can pass a single value as like to popup screen as "window.open('@Url.Action("ViewName", "ContollerName",new {id="ParameterValue"})'.
Is it possible to pass the current view to to popup window as a parameter like new {id="Parameter"}) ?
I've run into a wall with the ViewData construct, but not sure exactly where the limitation lies or the best way to get around it. I have a complicated View that needs to contain many dropdown listboxes. I am loading up ViewData objects in the controller for the view. Apparently, I have hit some limit and cannot add another ViewData object for another dropdown. I'm not sure if the limit is the number of distinct objects in ViewData, the amount of memory in my test server, or the overall amount of data I am trying to load into the ViewData collection.

I have a View loading a PartialView via jQuery. The PartialView has ViewData that the jQuery needs to access, but I can't seem to get to it from the jQuery. The code below uses the HighChart jQuery plugin (and it is just test code taken from the HighChart example page):

This jQuery is in the main view, because I don't know how I could put it in the PartialView with the document ready function. But by putting the call to the HighChart function in the callback of the get() function it works in the partial view. But accessing the ViewData doesn't...
How can I achieve this? I need to get the data from the PartialView action method in order to populate the HighChart data...
