Hello!
I understood, that locking entire screen is not great idea in most cases.
For example, i have frame and region with items and search bar (simple edit field).
When user fills edit field, i need update region. To demonstrate that something happening i want lock region with items.
To see what i mean, you can follow this link.
I created new lock indicator item and connected it to corresponding async event of edit control.
Now, new lock indicator opens when required, but overlay locks all screen.
How to lock only one region?
