Dear All,
I have two web applications one behind ISA and the other is accessible directly
How can I send the credentials to ISA login page and go directlty to the first web application?
I can connect using HttpWebRequest with the credetials and get the response but when I redirect to the web application I'm asked for the credentials again.

Best Regards

Design using MVP pattern

Hi,
I am trying to implement a site(Read/Update/Delete operations site) using MVP pattern. Also trying to keep the presentation layer UI agnostic(i.e. Presentation layer should work with a Web Client/Windows Client).
Now I have a domain object with around 30 fields/attributes and all of these fields are editable in the UI(View).

I want to propogate the change in any field to the Presentation layer. The only solution I can think of is to define 30 events!!! in the View and 30 handlers in the Presentation layer or define 30 setter methods in the presentation layer for the 30 event handlers in the view.

Am not comfortable with this design.
Can any one provide me a solution or a direction on this?

Regards,
Cybernate

First, why should the presentation layer work in two different presentation models?

You mean the controller?

I can see this:

Model <shared>
Controller <shared>
View - one instance for web, one instance for web form

That makes more sense to me.

I'm also assuming your changes are to "something" not just random fields, but fields that belong to an object.

So why not maintain the original object state in the controller:

Controller<T> where T: class

T _state;

Have a typed args, something like:

public class TypedArgs<T> : EventArgs where T: class
{
public T Value { get; set; }
}

Create an interface for your views:

public interface IView<T> where T: class
{
event EventHandler<TypedArgs<T>> Changed;
}

then you can raise Changed with the new entity in the view, and have the controller register. Just pass in IView to the controller so it doesn't care if it's a user control or a web form, and when Changed is raised, it can compare e.Value to the stored state and decide what to do.

Thanks Jeremy.
I tried to provide my question with an example.

I have a scenario where I have to display a view with around 30 fields(some are textboxes and some are Dropdowns) and the Business Object to represent the entity would be something like:
[CODE]
Parent
{
PField1
PField2
.
.
.
.
PField19
PField20

List<Son> Sons;
List<Daughters> Daughters;
}

Son
{
SField1
SField2
SField3
}

Daughter
{
DField1
DField2
DField3
DField4
DField5
}
[/CODE]

Am capturing/displaying the whole business entity in a single view.

Now the user can change the base fields of a parent or change the fields of a son/daughter.

Now how should I handle the change events for each field in the view, should I delegate the change events to the Presenter and then let presenter update the view. This requires to define 22 events in the View and then 22 delegate events in view and 22 event handlers in the presentation layer.

Somehow am not having a good feeling about this design.

Can you please advise?

Regards,
Cybernate

AFAIK, MVP is not well suited for web-applications. It works well with stand-alone applications. You may try the MVC model. ASP.NET has a MVC framework available. Give it a try.

That is ugly. You can have only one method in the presentation layer which takes an aggregate data structure and does the UI binding. Read this[^] MSDN article which takes MVP pattern in detail.

Thanks for your inputs.
I am not sure if I agree with you on MVP not suited for Web Apps.
Regarding the 30 Events statement I was being sarcastic.
Thanks for trying though.

Make sure that the Updatepanel updatemode is "Conditional" and set your textbox autopostback to "true"

I think the javascript function that you are calling doesnt exists which is fired when Radiobutton is clicked.
Or it must be thrown from the javascript function itself. Frown | :(
