View 2 RepliesMVC :: Model Binding Values In HTML Table Back To Controller
Aug 25, 2010Currently, I am working with ASP.NET MVC1 and am still learning about Model Binding and how values from a View are passed back to the Controller / Model. Specifically, I want take an existing Model, create a Table and populate the Rows of the Table, allow the user to edit some fields and pass it back.

ADO.NET :: Unable To Connect To DB2 Database From Visual Studio 2010 Express - Entity Data Model
Nov 16, 2010In Visual Web Developer-2010, I have been trying to connect to IBM DB2 Database after installing the DB2 9.7 client (both supports VS2010/.Net4) so that I can use "ADO.NET Entity Data Model", but while clicking "New Connection" I can only see the list of Data Sources and Data Provider only related to MS SQL server. This is totally blocking my work, I am not able to work further since I cannot even establish the connection to my db2 database using this new editor so that I can create the edmx files in the solution for non MSSQL databases. Kindly provide me the solution ASAP, since my further work is blocking due to this.

Entity Framework 4 - Update Database Schema From Model. Without Wiping The Table Data?
Jun 29, 2010I'm working on a new project where I have the luxury of working from a Model to Database approach using Entity Framework 4.
The project I'm working on is taking an agile approach where different phases will be rolled out over time.
Will the Model First approach work in my case? I noticed when you "Generate Database from Model" it recreates the entire schema from scratch which will obviously wipe all the data that is in the db. I was hoping for a more "Update Database from Model" approach where the db would just be altered to reflect the changes rather than recreated

MVC :: Save Changes To A Model In A Controller?
Apr 22, 2010i need to implement edit functionality for my model. among other fields my model contains record id in the database. when my controller is called i need to update the database record with the same id as the model using the fields in the model.
here is my controller:
[HttpPost]
public ActionResult Edit(MyModel m)
{
var r = my_datacontext.MyTable.SelectSingleOrDefault(x => x.id == m.id);
if (r != null)
{
r = m;
my_datacontext.SubmitChanges();
}
}
this does not work because m does not get added to the datacontext's ChangeSet. why? i fixed this by changing the signature of my controller action to receive FormCollection instead of the model, and by invoking UpdateModel manually. i think this is not the right way to do it.

MVC :: Really An Implementation Of Model - View-Controller?
Feb 8, 2010In MVCs with which I have worked, the Controller has the job of co-ordinating a number of views, consequent to some user action against the model.
However in ASP MVC, there never appears to be more than 1 view resulting from an http request (please correct me if I am wrong). Instead the "Controller" in ASP MVC appears to be a URL Routing Target.
Also, in my (admittedly limited) experience, the Model in MVC is intended to be a model of the problem domain of the application. However in ASP MVC, the "Model" appears to be a model of the
data binding of the corresponding view.
