View 1 RepliesOur site is expected to allow the user to do whatever they want from a number of different places. Except, that doing whatever they want really means firing off mini sequences of pages they must vist (or possibly abort from to go off to another task) before returning to their starting point. So, at any given time, the user has a list of pages they are allowed to go to, a list of pages they must go to in order to complete their task, and some end point they must eventually return to, all of which are constantly changing.
As an example, a user may choose to edit an order they placed, at which point they must step through a series of pages to edit the order. These pages to edit an order may be different based on the type of order they are editing, and they must return to whatever place they were at when they decided to start editing the order. They may also have certain options of other pages to visit during their order editing process.
I really need a good way to handle this for a large number of different scenarios, and allow it to be easily changed. Right now we are doing things like setting session variables when a user chooses an action and checking them within the page on button handlers to see what they are allowed to do or where they are allowed to go. I'd love to be able to abstract this out into something that can be easily examined in one place, or even data driven, and have some sort of navigation controller pointing them to the pages they can or must go.
I know this is not the right place to post this question but I dont know where to go. My question is this.I have a statemachine workflow, this workflow works fine until a new requirement is came. The new requirement is to add a new state and event driven but this event driven is fired if the document library item is updated where the workfow is embedded. Is this posible? if so what event activity should I place?
View 7 RepliesThe client wants to see a graphical representation of the workflow. In addition (let's say it is a workflow for processing orders), the client wants to see at what point in the workflow any given order is, indicated on the graphical workflow representation by a highlighted node or some visual queue.
All of this must be available via a web interface.
Was hoping somebody had some bright ideas for how to achieve this without writing extensive custom controls.
Does Workflow Foundation 4 offer anything itself that would assist toward this end?
I am new to workflow and just know some of its features. I want to do a project in WF. It will be a web based intranet application where user will be able to define workflow dynamically through web interface.Duration for completing a task can be many days.With these requirments I am not sure will use of WF helpful in quick development or it will increase work ?Please advice me should I try to learn WF for this project or should do it with C# and asp.net
View 1 RepliesWhen a button/link is clicked, I want this URL to be called followed by the execution of the following statements. The ASP.Net page is in C# btw.
Function A
statement A
call abc.apsx
statement B
abc.aspx is a silent page, doesn't display anything on the page but creates an output.txt file. So when abc.aspx is called, output.txt file is created and Statement B is executed seamlessly.
where i can get the entire flow of a web page request?I really want to know what erally happens inside (HTTP + IIS + page load)
View 6 Repliesthis question should be fairly basic. I want to control the flow of an ASP.NET page -- if a certain condition is met, I want to write out an error message and stop drawing the page. However, I also want ASP.NET to output correct HTML (i.e. not cut off in the middle). Right now I am doing this:
if (condition != what-i-want) {
Label_Error.Text = "Sorry, you messed up";
return;
}
And the problem with that snippet is that ASP.NET draws the rest of the defined page without cutting off after the error. I really don't want to make the whole page Visible = False and then undo it when someone is authenticated. Is there some good way to do this? I have tried Response.End() but that doesn't output clean HTML (or anything actually, since I'm checking in Page_Load). I've had similar experiences with Response.Close(), et al.
My basic question is how can we show a sequential workflow diagram on asp.net web page dynamically. using WWF can we do this?. i have gone throgh the some of forums/articles but i could not find right information anywhere. please suggest me the right path to achieve this.

I'm integrating a number of e-comm sites into different banks and decided the easiest method was to add in the dotnetcharge (www.dotnetcharge.com) library.It works well and means I can keep much of my code the same for each bank type and transaction.However, their support is a bit sucky (4 emails sent, 1 reply) and I'm utterly baffled on the 3D Secure issue.Does anyone have experience with dotnetcharge and 3D Secure?I have set the MerchantURL and the actual 3D Secure screen comes up - but I'm unsure how to get the system to 'flow' properly.Does anyone have any code examples or even pointers in the right direction?Failing that.This particular integration is with SagePay,which also has God-awful documentation and support.
Code for reference is as follows;

ASP.NET, web form model.Is there any sample code/site that demonstrate a couple samples for regular website patterns/ templates? Like if I want to use tab to switch between different pages, should I put the code in a single page or in different page, and treat each tab as a page.Or if in a search page (just a single search bar and button), should I display my result panel in same page using dynamically enable the result panel, or just to another page? I want to find a general design pattern/ template.

I most of the examples in web says Go to Visual studio 2005 or more, then slect Workflow Project type in new project dialog box. but in express edition i cannot see workflow as a project type, is this because of express edition or do i need to run any thing to get this project types in to VS express.
View 4 RepliesAll too often I find myself being required to design pages that flow through a series of steps. 1) Select from a set of options. Submit.2) Populate a page with results. Make changes. Submit.3) Do something based on the previous results. Submit.4) Confirm previous actions. Submit.5) Goto 1.An ecommerce site with shopping cart would be a textbook example of this.Now, there are any number of ways to deal with this. My question is, what is the recommended way to do it in asp.net? In PHP or ISAPI I would just use standard html controls, get the post data and do stuff with it, each on a different page

I have been doing Windows programming in .Net since last two years. Now I am shifting to web programming so I just stuck in understanding the fundamentals of web programming, after googling I came to StackOverflow to learn from all of you great guys.
My confusion is about how messages flow between systems in distributed enviornment ? I mean suppose I want to send a message "Hello" to a system connected to LAN or Internet, then what will be the steps taken to send the message.
Second thing is suppose my system is "A" and I wana send message to system "B" which is connected via a wire, so how the message flows on wire and how system "B" reads it from the wire ?
I've started using ASP.NET MVC on a project and have gotten a few working pages, but I recently ran into a problem where data I was carrying through a hidden field didn't carry for some reason. I can think of a couple of possible reasons and I could try things until something works but I prefer to work on observable empirical data. Thus the point of this inquiry.
I've got a controller (several), a model (several), a view (several), and data in the browser for the JavaScript to chew on. I can unit test my JavaScript code. The browser / view interactions go over the wire, and I can capture that either with Firebug or (if I want to punish myself) Ethereal. I can write unit tests for the controller and for components of the model. The thing that appears to happen in a pure "black box" is the mapping between the model objects and the view form fields. Somewhere in that process, it tries to map data from form fields into model objects before it hands a request to the controller and it tries to map data from the model objects to form fields when it processes the response. Even with the helpers in play, this is a source of bugs. There can be spelling disconnects, or a page might be inadvertently missing one of the fields of a model object because it didn't use it. It would be nice to know if a field didn't map and why.
Since it is happening on the server, this seems like the handoffs should be unit testable or at least loggable. The problem seems pretty bounded. I can't be the first person to have run into this question. Are there any hooks I can use for this? What are the best observation points in the framework to tap the process, both incoming and outgoing?
how to put what i am looking for. The best i can describe it is a flowchart type of layout that shows your all your ASP.NET pages and how they are linked to one another.
Example:
----------- -----------
|main page| |error.asp|
----------- /----------
-----------/ ------------
| login.asp| |footer.asp|
------------ /-----------
---------/ ------------
|Home.asp|---|Header.asp|
---------- ------------
/ ------------
--/----------- |Nav bar.asp|
|Products.asp| -------------
--------------
etc etc..
Is there any built-in things like that or 3rd party software that does what i am looking to do above?

View 1 RepliesI am building a medium to large application with ASP.NET MVC 1.0 (we'll upgrade to the latest after we meet some schedule commitments). The application contains a number of workflows, with a separate controller for each workflow, and the home controller owning the main page of the application. So, I end up with the home page, on which the user makes selections and then clicks one of a number of action buttons to proceed down a given workflow. For a given workflow, I seem to have the following flow between controllers:
homeController (home view) --> action-button --> workflowController --> homeController (completion view)
I figure the action-button does a post to the home controller, which the selections the user made are saved to session state in the appropriate model. The workflowController will handle things as the user moves through one or more views specific to the workflow, but then things end on a common completion page.My question(s):1 - Is this a reasonable way to break up responsibilities amoung multiple controllers?2 - How do I actual accomplish the hand-off to the workflow specific controller? I'd really like to avoid a redirect and the attendent round trip to the browser since controller structure is really an internal implementation issue and shouldn't impose a performance penalty on the user.3 - Is it possible to pass a model from the originating controller to the destination controller, or do I have to exclusively depend on persistent state to pass things to the "next" controller?
By "how does" I mean "by what mechanism" not "to what effect". Control doesn't return to the calling method after you call Server.Transfer("...");. At the language runtime level, how does this happen? Does it throw an exception or trigger something that aborts the thread? I'm just curious. What are other examples of this pattern (calling a method to terminate execution)?
