ADO.NET :: Return A Single Row From A Database As A Strongly Typed Object?
Nov 10, 2010
I have a products table whereby I want to return a single row via a product id and use it as a data object.
I have used a .xsd dataset and a product class where I return a dataset and add the values into the product object that I created but I don't like having to write code like
"Product[0].ProductDescription" to get the product description. Is there a way of returning is straight as an object rather than a dataset?

I am having a trouble while trying to create an entity with a custom view modeled create form. Below is my custom view model for Category Creation form.
[code]....
When i click on save button, it doesnt bind the category for me because of i am using custom view model and strongly typed html helpers like that
<%=Html.TextBoxFor(model => Model.Category.OrderNo) %>
My html source looks like this
[code]....
How can i fix this?

Just a quick question really but with the strongly typed views where MVC can autobind form fields to the propertys of an object I define, how does this work when supporting multiple forms on the same view?Is it possible to have two objects with different properties,
Object1 { Name, Age }
Object2 { StartDate, EndDate }
Then on the view have two seperate forms, one for each object and the controller can work out which object it is to post back because of the form which eventually gets posted back?

Okay, here's something that I could easily do the hard way and manually wire up each form element and save it to a datatable in memory, but there has to be a more efficient way to do it.
Here's what I have:
1. A strongly typed datatable and tableadapter in a XSD name Orders
2. A formview control which currently is connected to an ODS connected to the Orders tableadapter, this makes it easy to wire up the databindings for each form field in design view
I would like to:
- bind the the formview to an instance of the strongly typed datatable, and then save the dt to a session object without interacting with the actual database
- load forms on subsequent pages from the dt in session
- ultimately save the dt info to an actual database table on the third page
I've read some solutions where a custom class is created, but to me this seems like almost as much work as wiring up the form field to the table columns manually in code.

So my question is more in relation to what people consider to be the best practice and why:
I've been dropping literals into pages and repeaters and binding them in code behind for a while. Is this considered bad practice?
ie:
ASPX Page:
<asp: Literal id="litTextToInsert" runat="Server" />
Code Behind:
litTextToInsert.Text = objData.MyText;
OR (repeater):
[code]....
I personally dont like doing this as i find it makes it harder for me to know if someone changed the field name, or mis typed it during development - the other way you won't know until the page loads.
With the strongly typed version if something changes in your DAL etc the build will break - letting me know I've messed up.
Why do so many people appear to use weakly typed code in ASP.Net (in examples, MVC, etc)?
Am i missing something?

Given the benefits of using strongly typed views to eliminate typed errors and the use of lambda expressions why would one use a dynamically typed view? When I use them I don't feel as safe as with strongly typed views. Am I missing something? Is there a special use for them?

I have an application that is going to allow a user to create records of type Customer and Seller that have one section in common, but other fields that are unique to their types.
Both of these types will have an address block for their create view.
If I have a strongly typed Customer or Seller view, how can I use the view partial (containing the address block) that I've created? I've tried creating a view model, but I don't know how to have the create page inherit the Customer model and the addressBlock partial inherit the addressBlockForm partial model...

Long story short, I'm trying to add a few extra items to ViewData to make my life easier, and its an edge case that doesn't really justify its own model just for this one case. Keep reading for more specific details.
So I have a strongly typed edit view for one of my objects, everything works great until I try to put a dropdownlist on the view with an ID that does not match a property of my class.
I have this
[code]....
My expectation is that in the controller action that accepts the POST, I will manually use the FormCollection[] to read out that ID and populate MyOtherModel with the correct ID.

How much time is spent compiling a view in ASP.NET?Of course I don't expect anyone to give me a number, but I think it's interesting to have an idea of how much time this takes because it could influence the way we implement things.For example, if the time is significant , then I might try to put every result that I need to display in the view in a model class instance (created just to hold the values in such a way that I don't even have to test for objects with null value) and then minimize to the maximum (uh?) the amount of C# code in the view thus decreasing the amount of time necessary to compile the view.Question Does this make sense? Give some thoughts on this one.

I'm currently working on a 3-tier ASP.NET application (UI, BLL & DAL). The DAL uses a strongly typed dataset that I've created with the VS Dataset Wizard. My question is, what is the best way to handle exceptions originating from the BLL and DAL classes. I googled a bit and it seems that the most commonly used practice is to create DALException and BLLException classes and throw your own message. Is this the way forward? how this can be done for an automatically generated DAL? What are the best practices?

Can my strongly typed view use a generic with a constraint? The type I want to pass to the view is
RoleGrantedToPerson<T> where T: Aggregate I don't know what T is at design time, only that it is a child of the base class 'Aggregate' I have tried using
System.Web.Mvc.ViewUserControl<RoleGrantedToPerson<Aggregate>>
but at runtime I get an error that the type of the view model supplied does not match the type required.
Is there some syntax/method to accomplish this?
