How to make it possible to enter data in a field that receives the calculated data,
Explanation in the picture

Hello Kriss,

you can't as well as you can't enter data in results in the worksheet (or in result's cells in excel, f.e.); what are you trying to do exactly?

Hello Davide Carpi,

For example,
the data retrieved from the database or a calculation
and the User can change this value or accept the given value.
(In other words - the default value)
as a variable a, as shown in the picture above, because we initially set the value that the user can change it

I understand the point, as for now the only way is to change the logic of your script (f.e. creating a tab with database-driven inputs, another with user-driven inputs) or to use controls (checkbox, combobox...) to drive the behavior

Thank you, Davide Carpi!

Yes, I also thought about this solution.
If there are no other suggestions, I will use your proposed solution.

Thought about it and would like to offer few solutions to this problem.
The message to the respected Davide Carpi, the developer controls.

Numeric up-down - control

1. To add to - Canvas setting - Tag - value

2. In settings add a property to - Hide the sliders - (increase/decrease)
get visually similar to control - TextBox


ComboBoxList - control

1. In settings add a property - IsEditable
like in standard controls (WPF, WinForms)
- for manual input of values

2. In settings add a property to - Hide the sliders


With respect
