MVC :: Binding Drop Down List From ViewData?
Mar 11, 2010I keep getting this error and i just can't figure it out:
The ViewData item that has the key 'CampaignId' is of type 'System.Int32' but must be of type 'IEnumerable<SelectListItem>'.
My Controller:
//show empty form
[AcceptVerbs(HttpVerbs.Get)]
public ViewResult Index(int? CampaignId)
[Code]....
I do need to have "CampaignId" in there because I'm populating some "partial views' based on this "CampaignId" that is selected (drop down)
MVC :: Binding Controller & View Without ViewData?
Feb 13, 2010I like ASP.NET MVC, because I like to have direct access to my web site's structure. However there's 1 thing that I don't like.
In Ruby on Rails to send data from Controller to View is really easy:
# Get a user in controller
@user = User.first(:id => 1)
# Display him in a view
<%= @user.id %>
In ASP.NET MVC it's much harder
// Controller
User user = new User(1);
ViewData["user"] = user;
// View
<% User user = (MyNamespace.User)ViewData["user"]; %>
<%= user.Id %>
With this ViewData thing all benefits of static languages go away, and we waste time boxing/unboxing objects.
P.S. Don't tell me to use Model object, because this is also true for other variables like integer.
And another question:
I'm trying to implement a comfrtable access to data. Since I can't use LINQ to SQL as I use Postrgresql, I have to do it on my own. I'm tired of direct SQL queries, so I'm trying to implement something like this:
User user = User.Find("first_name" => "Bob");

C# - What's The Difference Between Binding Data To The Repeater In The Mark-up Or Binding It Programatically
Mar 4, 2011What's the difference between binding for example a column called ("Name") in both cases ? and is there's any performance difference ?1- Assigning the data in the mark-up
<asp:Label ID="Name_Lbl" runat="server" Text='<%# Eval("Name") %>' ></asp:Label>
2- defining a control object for every control inside the repeater ItemTemplate and find it and then assign the data in the column "Name" to ite.Item.FindControl("Name_Lbl")
MVC :: PartialView Outside Of Form - ViewData
Mar 16, 2011I 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.

Creating Dropdownlist From ViewData
Jul 22, 2010Does 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 />
<%
}

MVC ViewData Not Rendering In View
Jul 16, 2010I 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.

MVC :: Unable To Increment A Value While Using ViewData?
Apr 7, 2010The 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.

MVC :: Sending Viewdata To Another Controller?
Mar 18, 2011I 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.

MVC :: Size Limitations Of ViewData?
Jul 26, 2010I'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.

How To Access ViewData In A PartialView From JQuery In MVC?
Dec 29, 2010I 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):
<script type="text/javascript">
var chart1; // globally available [Code]....
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...
