Hi All, @sanzoghenzo
I’m implementing a UI using WPF to create grids in Revit. To allow users to switch between numeric values (‘1, 2, 3, …’) and alphabetic values (‘A, B, C, …’) for grid names as shown below:
I used a ComboBox to display symbol types in a dropdown list; however, I’m struggling to set up event handlers to manage the selection for each grid orientation (X and Y) and to prevent the user from selecting the same symbols for both.
Note: As shown in the image above, I want to retain the content describing numeric and alphabetic symbols as they are in the dropdown, while using the actual symbol values in the code-behind.
Pls check my code below:
