I have an xaml file with several tabs in it$.$ Render Groups, Views, Materials, and Design Options.

$1.$ I want to make it so that when I start up the XAML file and load up the window which contains all the tabs$,$ the tabs for Views, Materials, and Design Options are hidden.

$2.$ When I select an item in a listbox in the Render Groups tab and click a button called Modify, the changes the title of the window to $$Modifying $\{$selected item$\},$ hides the Render Groups tab, and shows the $3$ tabs: Views, Materials, and Design Options

$3.$ When I click a button called $$OK$$ it hides the $3$ tabs: Views, Materials, and Design Options, and shows the Render Groups tab again.

To help integrate this with my code, I have provided some of my current code:

Main class:

class ViewModel$($my$\_$WPF$)$:

context$\_$mode $=$ 'show'

view$\_$mode $=$ 'singular'

context$\_$transp $=0$

context$\_$color $=$ Color$(255,255,255)$

warning$\_$color $=$ Color$(255,0,0)$

count$\_$views$\_$total $=1$

count$\_$view$\_$current $=1$

def $\_\_$init$\_\_($self$)$:

path$\_$xaml$\_$file $=$ xaml$\_$path

wpf$.$LoadComponent$($self$,$ path$\_$xaml$\_$file$)$

self.UI$\_$ListBox$\_$DesignOptions.ItemsSource $=$ new$\_$design$\_$option$\_$names

self.UI$\_$ListBox$\_$FamilyGroups.ItemsSource $=$ new$\_$family$\_$group$\_$names

self.UI$\_$ListBox$\_$MaterialGroups.ItemsSource $=$ my$\_$material$\_$groups$\_$list

self.UI$\_$ListBox$\_$Views.ItemsSource $=$ wrapped$\_$views

self.UI$\_$ListBox$\_$RenderJobs.ItemsSource $=$ self.render$\_$jobs$\_$list

self.UI$\_$ListBox$\_$RenderGroups.ItemsSource $=$ my$\_$render$\_$groups$\_$list

self.set$\_$owner$($uiapp$)$

def set$\_$owner$($self$,$ uiapp$)$:

# Obtain the Revit main window handle

revit$\_$window$\_$handle $=$ uiapp.MainWindowHandle

window$\_$interop$\_$helper $=$ WindowInteropHelper$($self$)$

window$\_$interop$\_$helper.Owner $=$ revit$\_$window$\_$handle

def show$\_$window$($self$)$:

self.ShowDialog$()$

if $\_\_$name$\_\_==\text{'}\_\_$main$\_\_\text{'}$:

x $=$ ViewModel$()$

x$.$show$\_$window$()$
