Body
The basic idea is that I have a website and a workflow. I need to capture button clicks from aspx pages in my workflow. I have a solution with a worflow project and a website project, and the web.config and global.asax have been set up to work with WF. Persistence services are also set up. I have created a StateMachine workflow. There are several states (StateActivity) containing EventDrivenActivity instances, inside of which are HandleExternalEventActivity instances. To set up the latter correctly so the application could compile, I created an interface decorated with the ExternalDataExchange attribute, and exposing the necessary events. I then created a class that implemented this interface. That's as far as I got. Now I need to connect the class to my aspx page; events on the page need to trigger the events in the class. My code looks something like this: <pre><code><ExternalDataExchange()> _ Public Interface ICatWorkflow Property RequestId() As Guid ... Sub requestInfoEmail() ... Event onReception(ByVal sender As Object, ByVal e As ExternalDataEventArgs) End Interface Class MyObject Implements ICatWorkflow Public Property RequestId() As Guid Implements ICatWorkflow.RequestId ... End Property Public Sub requestInfoEmail() Implements ICatWorkflow.onReception ... End Sub Event onReception(ByVal sender As Object, ByVal e As ExternalDataEventArgs) end class </code></pre> On my form.aspx âge, there is a button, and on form.aspx.vb page, there is a corresponding event handler: <pre><code>Protected Sub btnReception_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnReception.Click ... End Sub </code></pre> Where to go from here?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
