Block operation having Select operations with corresponding Controls on Form
This topic describes how the conversion of Block operations that include Select operations, with corresponding Controls on Form, is executed.
In this case, the Block's condition determines the parking on the controls within the Block.
The conversion process takes Block's condition and implements it into AllowParking property on controls, and to condition of Control Verification handlers, if needed.
RM Compatible logic:
Converted to event-driven mechanism:
Change of behavior:
In RM Compatible logic, once the Block's condition allows us to park on first control in the block, we can park on all the controls in the block, even if the condition changes meanwhile.
After conversion, the Block's condition is attached to AllowParking property on the controls. And if the condition changes meanwhile, then this could affect parking on the controls.
