Here is a situation that you might find useful while working with repeat grids.
Scenario: How do I display a row in the repeat grid so that it appears as readonly or editable based on some condition?
Solution: To make an entire row editable or readonly based on a condition, you can use a section in the grid cell and configure it to evaluate based on a condition (when rule/expression).
You can check the pyPreGridUpdate activity to see the list of actions such as EDITROW, SUBMITROW and so on which will be set on Param.gridAction variable while performing actions on a grid. Based on the Param.gridAction value a condition on the section can also be configured.
