Passing Messages To The User In MVC2?

Jun 29, 2010

I am using ASP.NET MVC2 for my project. I want to send the user confirmation messages after actions.

Ideally: User clicks on a link with a query string (i.e. a link to delete an entry) The controller does what the link says, creates the success message, and uses RedirectToAction to get rid of the query string from the URL. The new action displays the success message.

Display And Update Data In MVC2?

Mar 7, 2010

Table Product
Product Id
Product Name
Table ProductSupplier
ProductSupplierId
ProductId
SupplierId
Table Supplier
SupplierId
SupplierName

I have the above 3 tables in my database, ProductSupplier is the lookup table. Each Product can have many suppliers. I am using Entity Framework. Using Web Forms it was fairly easy to display a Product on a web page and bind a repeater with the suppliers information. Also, with Web Forms it was easy to Add new Product and suppliers, the linkage seemed easy.

How do you do this sort of functionality in MVC? In the Create View below, I want to be able to Add the Supplier as well. Is there a better approach that I might be missing here? This is how I did it with Web Forms. Beyond the code below I am totally lost. I can show data in a list and also display the Suppliers for each Product, but how do I Add and Edit. Should I break it into different views? With Web Forms I could do it all in one page.

namespace MyProject.Mvc.Models
{
[MetadataType(typeof(ProductMetaData))]
public partial class Product
{
public Product()
{
// Initialize Product
this.CreateDate = System.DateTime.Now;
}
}
public class ProductMetaData
{
[Required(ErrorMessage = "Product name is required")]
[StringLength(50, ErrorMessage = "Product name must be under 50 characters")]
public object ProductName { get; set; }
[Required(ErrorMessage = "Description is required")]
public object Description { get; set; }
}
public class ProductFormViewModel
{
public Product Product { get; private set; }
public IEnumerable<ProductSupplier> ProductSupplier { get; private set; }
public ProductFormViewModel()
{
Product = new Product();
}
public ProductFormViewModel(Product product)
{
Product = product;
ProductSupplier = product.ProductSupplier;
}
}
}
ProductRepository
public Product GetProduct(int id)
{
var p = db.Product.FirstOrDefault(por => por.ProductId == id);
p.ProductSupplier.Attach(p.ProductSupplier.CreateSourceQuery().Include("Product").ToList());
return p;
}
Product Create View
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master"
Inherits="System.Web.Mvc.ViewPage<MyProject.Mvc.Models.ProductFormViewModel>" %>
<%= Html.ValidationSummary("Please correct the errors and try again.") %>
<% using (Html.BeginForm()) {%>
<fieldset>
<legend>Fields</legend>
<div class="editor-label">
<%= Html.LabelFor(model => model.Product.ProductId) %>
</div>
<div class="editor-field">
<%= Html.TextBoxFor(model => model.Product.ProductId) %>
<%= Html.ValidationMessageFor(model => model.Product.ProductId) %>
</div>
<div class="editor-label">
<%= Html.LabelFor(model => model.Product.ProductName) %>
</div>
<div class="editor-field">
<%= Html.TextBoxFor(model => model.Product.ProductName) %>
<%= Html.ValidationMessageFor(model => model.Product.ProductName) %>
</div>
<div class="editor-label">
<%= Html.LabelFor(model => model.Product.Description) %>
</div>
<div class="editor-field">
<%= Html.TextBoxFor(model => model.Product.Description) %>
<%= Html.ValidationMessageFor(model => model.Product.Description) %>
</div>
<p>
<input type="submit" value="Create" />
</p>
</fieldset>

JQuery Validation With Data Annotations In MVC2?

Apr 8, 2010

I am trying to make some sense of this validation stuff in MVC2. I followed various walkthroughs, all them for betas/rcs... and I cant' get anythign to happen. Note: THIS JQUERY - NOT THE MS AJAX STUFF!I have referenced MicrosoftMvcJQueryValidation.js which i got got the mvc2 futures lib.

My model is:

[Code]....

The form bit of my ViewPage<User>:

[Code]....

As far as I can see the only additional thing that is being rendered is this:

[Code]....

Which is interesting/annoying for a few reasons. Firstly all of my annotations appear to have been ignored.Secondly FormId isn't even marked as required, and as this rendered text was taken from a page loaded with a null Model (add mode) the FormId field isn't in the form. Finally, this doesn't even result in any actual validation occuring (on the client side). All the server side validation is working fine.See I am using PasswordFor instead of EditorFor. Because someone at MS testing dropped the ball there. Yes EditorFor renders a password field, but it behaves differently to PasswordFor.. the value of the Password field is sent to the client (set in the value
attribute of the field). Fail.

MVC2 View Model For Multiple View Forms And Data

Aug 26, 2010

one thing that has been puzzling me since learning MVC2 is the following case scenario: I have a view which contains two latest news lists, a login form and a signup form. Every example I found on Views and View Models so far has a one-to-one example such as a simple login form etc. But how do I create a model that provides the properties and validation for a login and signup form and manages the data for the news lists. can I pass multiple models in the strongly typed view? When I created one model the form validation would fail as it expects all fields - login and signup to be filled. I am missing some advanced examples or information.

Forms Data Controls :: Syntax For Passing ListView Data To SQL Input Parameters?

Dec 11, 2010

I have a ListView displaying data from Table A using a SqlDataSource.

I want to take the displayed data (and these are just the standard columns representing fields in Table A) and store them in Table B using a Stored Procedure

(The scenario is much more complex but I've left out anything not relating to this exact problem).

I've added a Button to the ListViews ItemTemplate and I'm using OnItemCommand to create a Sub for its "Click" in the Code Behind.

This is a simplified chunk of the SQL I'm using to insert the ListView's fields into Table B using the Stored Procedure "InsertCart":

[Code]....

Where I've highlighted "Description" in the last line. In a GridView, this would be enough. Description is a Column name in Table A and B and iy's an Item in the ListView. But I'm realising that, with ListView's, the data binding is not as "automatic" as a GridView. Just using the columnname is not enough.

What do I use instead of the word Description to reference this column in the Parameter?

Forms Data Controls :: Gridview Not Passing Parameters To SQL Data Source?

Feb 13, 2011

I have a gridview and I have an edit template for one control. I have a drop down box in this edit template so that you can select a value from it and then when you hit 'Update' the value from the drop down box is committed to the updated record. Unfortunately when I do hit the update button I get a fault that the "Status" field cannot be null.

Here is the code that picks the value from the drop down value and assigns it to the new values list:

Forms Data Controls :: Passing The Underlying Data Of The Databound Control?

Mar 30, 2010

In my asp.net web page i have a dropdown box. Say like i have to bind EmployeeName to this dropdown box to show up as items.

I am using a dataTable to bind to this grid by having two columns in DataTable (EmployeeId and EmployeeName). But i am only binding the EmployeeName to the dropdown list box.

In the UI, after the user selects an Employee, I need to pass that employee's id to a function. Is there any way, i can directly pass the underlying data (EmployeeID in the DataTable attached to this dropdown), when the user selects the EmployeeName from the dropdown. Or i will have to make a roundtrip to the database and get the selected Employee's Id and then pass it to the function.

Web Forms :: Passing Data Between 2 Web Applications?

Jan 31, 2011

I would like to implement the following functionality between 2 web applications:

a) Web application one contains a button, which, when pressed launches another web application.


b) The second application contains a form that is filled in by the customer.

c) After filling in the form, the second application validates the information and returns a 5 digit code to indicate whether validation was successful.

d) Web application one then displays the status and asks the user to continue with other steps.

Is the above scenario possible? Is it possible to transfer data between 2 seperate web applications? I have considered using a query string, database and flat file to trasnfer the data from one application to another. Which of these (if any) would be the best choice?

App B - http://MachineB/default.aspx

I tried encrypting the data using AESCryptoServiceProvider and it returns a byte[]. Now how would I transfer it over to another application? Via query strings?

Query strings does not take a byte[] parameter. So I am clueless now.
