I have a byte array of an image on the server side.
I have an img tag on my View page.
I'm wondering how to be able to use the byte array as the image source of the img tag.
I'm retrieving the byte array in my model, passing it back to my controller method and then I'd like to store it in ViewData somehow.
Then in the $(document).ready jQuery function of the View page somehow set that byte array as the source for my IMG tag.
Is this possible?
Is there any simple method to pass viewdata to masterpage. For example, I create a viewdata["test"] in the testing controller. I pass it to masterpage so the masterpage can show this value.Is there any simple method to do it? Can I use session to do it and how?
View 6 Repliesmaking 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 :
[Code]....
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.
View 4 RepliesI am new to MVC, i tried to pass the viewdata value from Index action of homecontroller to the textbox i have on Index.aspx.
I am getting the view with the label and the textbox but i am not able to get the value that passed on from the controller
The below is the .aspx file
<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %>
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.
I created a base Controller for the other Controllers to derrive from, and in that controller I overrode the OnActionExecuting method so that each time any Controller executes a method, I can run some code. In that code I added a value to ViewData, and in the Master View I want to either display certain items or not based on the value of the ViewData item set. The problem is, once I get to the Master View, the ViewData doesn't have anything in it. I am not sure what I'm doing wrong.
View 1 RepliesI 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");
I want to pass a message from the controller to a view using Viewdata. Here is my code:
public ActionResult Create(FormCollection createPage)
{
try
{
......................
ViewData["Message"] = "Success - rec added!!!!" ;
return RedirectToAction("Index");
}
catch (Exception e)
{
ViewData["Message"] = "Exception: " + e.ToString();
return RedirectToAction("Index");
}
On my View I have:
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<h2>::><%: ViewData["Message"] %><::</h2>
<h3>==><%= ViewData["Message"] %><==</h3>
<p>
This is Index.aspx page in Controller folder
</p>
</asp:Content>
I am getting result with empty ViewData["Message"]
ViewData["Title"] is accessible only the current view? or it is possible to access other views also?
View 4 RepliesWe are trying to fill JqGrid in ASP.NET MVC3 application where datatype is set to 'jsonstring' and in it's action controller, we set the json data string in ViewData and retrieve the same in javascript function where we used it to fill the Jqgrid.
// Action code
[Code]....
// Javascript code to fill Jqgrid
[Code]....
[Code]....
There is an error while filling grid and when i alert the data it shows " in place of " in data, as below.
{{"total":2,"page":1,"records":2,"rows":[{"RequestID":"1","cell":["CPU","DELL OptiPlex 745","DELL","OptiPlex 745","5"]},{"RequestID":"2","cell":["CPU","TOSHIBA Tablet Portege 3500","TOSHIBA","Tablet Portege 3500","10"]}]}
[data displays fine on this post :) ]
The decodeURI function do not work on strData and it always show " in place of " in the data. We do not want to replace the " with " in a loop as it slow the page with large data.

I need to pass many records with number of fields(i.e 5rows and 5 columns) in either array or table form to oracle for processing. Is it possible to pass array/table from asp.net pages? If no, any solutions for this? I have been thinking of passing it as string concatenated with delimiter and split it. Seems like it is not appropriate as i have to pass 5 strings(5rows)
