# Main function

def main():
    modeless_form = Areatool_ModelessForm()

# Run the main function if this script is executed
if __name__ == "__main__":
    main()
2

the way to run this is

if __name__ == '__main__':
    main()
3

Script is running issue is it is not updating the Parameter Comment or somewhat it is not calling the populate_comments_parameter function

Hi @saurabhsjha,
Remember to wrap your code in triple backticks (```) for better readability.

I see that the sent_Revit method is not indented properly, you need to be consistent with tab and/ or spaces since python is picky about it!

Also: in the Areatool_ModelessForm.__init__ method you have 2 duplicate lines, and thus you are calling self.Swoh() twice. I don’t know if this could lead to problems, but it surely not necessary.
I prefer to call the show method outside of the init, to let the code that calls the class to be in control of the window.

Random suggestion: move all those lists inside dictionaries with the possible selected area values as keys, so that you just access the dictionary instead of having to do all that if/elifs…

Thank you for your recommendation. I have just started experimenting with WPF, as I was using forms for a simple function before. I apologize for my mistake. Now that I have resolved the Sent_revit function and will try to make the dictionary load all the data (in fact, I will create the data in Excel and read from there), I am facing a new issue that was not there before. The issue is that if I select another dropdown item from Area type 01, then the function Area01_selector_SelectionChanged says that MarketRental_Names are not defined, but they are global parameters.

Hi, I would suggest to switch right away to a dictionary of dictionaries, like so:

# reverse the order of the list, putting the lowesl level at the top...
MarketResidential_Services_Names = [...]
# ... so that higher levels can use them...
MarketResidential_Names = {
    "Unit": MarketResidential_Unit_Names,
    "Common": MarketResidential_Common_Names,
    "Services": MarketResidential_Services_Names,
}
# ... and so on until the top level
Area01_Names = {
    "Market Residential": MarketResidential_Names,
    "Market Rental": MarketRental_Names,
    "Affordable Rental": MarketRental_Names,
    "Social Housing": SocialHousing_Names,
    "Hotel": Hotel_Names,
    "Office": Office_Names,
    "Commercial": Commercial_Names,
}

You then have only one variable that can be passed to the class in the __init__ method, instead of using globals (with the added benefit that you can reuse the for with different data).
The selection changed methods greatly simplifies to a level that they can call the same function with different arguments:

class Areatool_ModelessForm(WPFWindow):
    def pre_actions(self):
        self.simple_event_handler = area_text_SimpleEventHandler(mark_area_parameter)
        self.ext_event = ExternalEvent.Create(self.simple_event_handler)

    def __init__(self, area01_names):
        self.pre_actions()

        xaml_file_name = "Areatool_ModelessForm.xaml"
        WPFWindow.__init__(self, xaml_file_name)

        self.title_text.Text = "CDA Area Tool"
        self.sub_text.Text = "Define the Area Parameter for CDA Standard making Scheduling Standardize and Easy"
        self.set_image_source(self.logo_img, "CDA.bmp")
        # Add an event handler for the Area01_selector
        self.Area01_selector.SelectionChanged += self.Area01_selector_SelectionChanged
        self.Area02_selector.SelectionChanged += self.Area02_selector_SelectionChanged
        self.Area03_selector.SelectionChanged += self.Area03_selector_SelectionChanged

        # here we store the input data and prepare the attribute to store the chosen levels names
        self.area01_names = area01_names
        self.area02_names = {}
        self.area03_names = {}
        self.area04_names = []
        self._refresh_selector(self.Area01_selector, self.area01_names)

    @staticmethod
    def _refresh_selector(selector, names):
        selector.Items.Clear()
        for name in names:
            selector.Items.Add(name)

    def Area01_selector_SelectionChanged(self, sender, e):
        # storing the area02 names of the selected area01, then calling the refresh
        self.area02_names = self.area01_names[self.Area01_selector.SelectedItem]
        self._refresh_selector(self.Area02_selector, self.area02_names)

    def Area02_selector_SelectionChanged(self, sender, e):
        # Handle the selection changed event for Area02_selector
        self.area03_names = self.area02_names[self.Area02_selector.SelectedItem]
        self._refresh_selector(self.Area03_selector, self.area03_names)

    def Area03_selector_SelectionChanged(self, sender, e):
        # Handle the selection changed event for Area02_selector
        self.area04_names = self.area03_names[self.Area03_selector.SelectedItem]
        self._refresh_selector(self.Area04_selector, self.area04_names)

# ...

def main():
    areas_form = Areatool_ModelessForm(Area01_Names)
    areas_form.Show()

# ...

I left off some things, such as when you select a different name in the Area01 selector, the Area03 and Area04 lists (and the related area0X_names attributes) should be emptied.

Thank you so Much @sanzoghenzo i was struck on it from last week dictionary made it simpler
