Vista - Sequence of steps using workflow foundation in ASP.NET

Hi,

I started to know about WF when I looked into
http://www.masteringbiztalk.com/atlasworkflowdesigner

I have a similar requirement. My objective is that I need to have
similar UI. But I need to have an execute button which will do some
processing based on the workflow generated using drag and drop. How
can I do that ? I mean, is the workflow saved somewhere where from I
can parse it and fire different tasks based on the activity sequence ?

Is it necessary to use database to save the workflow ? Can't I use an
xml file ?

Workflows are persisted to either XAML (used to be XOML) which is just
XML or to VB.Net/C# using CodeDom.

I always try to persist to XAML. This means that some of the activities
(like the Code activity) will not work.

You could write your own activity though that exposes a string property
that the person designing the workflow would populate and the activity
would compile and execute using CodeDom.

Bryan,
Thanks for replying.
I saw that the workflow activities are pre-defined (like delay, ifelse etc.)
What if I don't want to use any of these and I just want to use my own couple of activities like ActivityA, ActivityB and so on....
I am sure WWF must be having this kind of functionality but I am just not able to find it.
Where can I read about all this ?
Thanks in advance

This functionality does exist and it is easy to implement.

The best place to read about this is http://wf.netfx3.com/
