Built in Post function to CALL my own IExternalCommand in my own WPF window

[jlpgy]

Hi:

I want to trig some Revit transactions from my own WPF window or page.

But I as well want to take advantage of the Revit built-in External Command function. Because I can return success, failed or canceled signal back to Revit main process, and Revit can handle it by popping out a built-in dialog conaining error message and highlighting the error elements.

For example:

I click a button in my own WPF dialog. In the Click event handler, I'd like to call some method like "PostExternalCommand( IExternalCommand myOwnClassInstance) ". And inside this ExternalCommand.Execute(), I can do lots of different tasks as my wish.

The point is that I only have to wrap some codes in the same class, and reuse it both in my own WPF dialog, and in Revit RibbonTab.

Is there any idea?

thanks a lot!

You want to investigate the IExternalEvent framework.  The idea is that you will (from your WPF click handler) tell Revit that you want it to run a function.  myExternalEventHander.Raise().   See the ModelessDialog sample in the SDK for an example of how this is done.

in terms of wanting to use task dialogs and return Autodesk.Revit.DB.Result, you can always return a "Result" enum from any of your own functions.  In the event handler, you are in a valid Revit execution context so you have access to Revit from there.
