Window WPF with work in Revit

1

Good evening! Please tell me if it is possible to create a script based on using Dynamo+IronPython with WPF, in which I give the output a list of elements, according to which the selection box is created, while the wpf window does not close and i can work with a 3d view, and then select the next selection box in the script window and again we work with it until the whole list ends. I ran into a problem, I don’t understand if there is any command so that window wpf does not close and there is an opportunity to work in Revit.

I think you’ll need to make an addin to achieve such an outcome. Dynamo tries to run the script completely, and whilst you can use packages like data shapes to generate forms, they typically dont allow you to continue working. Some inputs let you switch to revit to select model elements, but not keep working generally.

Many thanks! And tell me on what such an add-on can be made?

Visual studio and c#, typically.

I have a sample available here for WPF window creation with C# and Visual Studio. However, you cannot (currently) leave a window open in Dynamo while other things are happening. Dynamo is very sequential in its behavior.
See @c.poupin’s reply below.

You can use a non-modal form

an example with IronPython
test Wpf no modal form

import clr	
import sys
import System
sys.path.append(r'C:\Program Files (x86)\IronPython 2.7\Lib')
sys.path.append(r'C:\Program Files (x86)\IronPython 2.7\DLLs')

#import Revit API
clr.AddReference('RevitAPI')
import Autodesk
from Autodesk.Revit.DB import *
import Autodesk.Revit.DB as DB

#import net library
from System.Collections.Generic import List

#import transactionManager and DocumentManager (RevitServices is specific to Dynamo)
clr.AddReference('RevitServices')
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

doc = DocumentManager.Instance.CurrentDBDocument
uiapp = DocumentManager.Instance.CurrentUIApplication
uidoc = uiapp.ActiveUIDocument
app = uiapp.Application
sdkNumber = int(app.VersionNumber)

try:
	clr.AddReference("IronPython.Wpf")
	clr.AddReference('System.Core')
	clr.AddReference('System.Xml')
	clr.AddReference('PresentationCore')
	clr.AddReference('PresentationFramework')

class MyForm(Window):

But unfortunally you cant run Transaction in Modeless form

For transaction, it’s necessary to use Event (idling-event or ExternalEvent)
