CslaActionExtender sample?

Hi Rocky,

I am just exploring the new CslaActionExtender for Windows Forms applications.
Can you provide any examples on how to use this?

Just played with it, add it to a form and set its datasource, change some properties if you will. The buttons on the form gets new properties, named ActionType, CommandType, DisableWhenClean, PostSaveAction, RebindSaveAction. I think these can make RebindUI method in forms obselete.

I cannot make it work, though. It seems at some point public method ResetActionBehaviors should be called, but even called manually returns error.

Well, I had set it up like you mentioned, but then remembered that Rocky mentioned (I think it was in the last DNR show),
that we have to add the control and set all properties in code, using the designer would not work.

If you do so, it works to some extent (still beta).

Issues I found:
The WarnOnCancelMessage should not appear when the object is plain New without any property changes yet.
Cancelling should always disable the controls. It does not disable the buttons after a save (see below).
The cancel action only works till the first save! Try to cancel a modification on a previously saved object,
and you will be forced to restart the application as the form does not respond anymore!
[EDIT]
Well, after adding a BindingSourceRefresh control to the form it works better, but still not on a reliable basis.

But after all, this is the control all WinForm-developers have been waiting for! Smile [:)]

Miguel Castro wrote the control and contributed it to CSLA, and he just provided a sample:

Hopefully that helps.
