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...
Access Viewdata From JQuery Without Using Hidden Field?
Nov 20, 2010I am saving "Instruction" in CreateInstruction view. This view has partial view "CreateInstnAttribute" which saves "Attributes" related to this Instruction. It requires the InstnID as foreign key. The Instruction is saved using JQuery to avoid postback. So how can I get the InstnID to save the InstnAttribute? I tried HiddenField to save InstnId but I am not able to receive the value there. Can we use viewdata directly in JQuery?

How To Display The Image On MVC Page By Using Data From The ViewData
Jul 7, 2010I'm doing kind of wizard application that captures information on Contacts. The process of collecting information involves 4 pages. On one of the pages, the user is invited to upload is picture. The last page is called "preview before saving" where the user has 2 choices: (i) Go back to previous pages to make corrections or (ii) click save button to save data to DB. To be able to keep the same data all along those steps, I'm using tricks, such as serialization/deserialization, and TempData[]. On the preview page, I'd like to display all the information entered by the user, including the picture he uploaded.
Here's the basic structure of the image tag.
[Code]....
the src attribute takes values such as, src="../../Content/myPicture.gif or
src = "<"%=Url.Action("Action", "Controller", "RouteValue")%>"/>
In my case, None of the above is applicable because the data needed to display the picture are in the model.My object model has 2 properties called ImageData and ImageMimeType.
My question: How to display the image on an ASP.NET MVC page by using data from the ViewData.model [as opposed to getting data from remote location using for instance Url.Action()]

Finding New Data Access Best Practices / How To Handle Data Access, And Data Manipulation And Display
Dec 15, 2010I've been out of the ASP.Net arena since 1.1, and I'm starting to get back into it after a hiatus.
In the past, I would generally create SqlDataReaders, wire them up to pull from tables in a database via direct sql or accessing database views (mostly in MSSQL), grab the data, and display it in some datatable, or datalist.
Modifying data would usually be calling a stored procedure in the database to add/modify data, and then retrieve it afterward.
Now that I read up, I see there are alot of new things in ADO.Net world; strongly typed datasets, auto-generated adapters, etc.
My question is, does anyone have a good reference on best practices (or a book recommendation) on how to handle data access, and data manipulation and display now? I'm assuming that there are more automatic ways to show and manipulate data than before, but the new details are quite vast (which is good), but slightly overwhelming for me.
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 :: 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.

This is just pseudo-code so forgive any obvious errors, is there a better way to be doing this?
