Show info dialog based on value of selected grid line

Question

In the prospects form (smmBusinessRelationsListPage) i want to make a modification for the following:

If a grid line is selected and CheckboxA of that line is checked, then show a dialog: "Checkbox is checked!"

My first thought is to build this check in the active() method of the form smmBusinessRelationsListPage

What is the best way to accomplish this? Do i need a specific function to check the line?

Or would:

if (checkboxA == true) {
info ("Checkbox checked!");
}

be enough to check the selected line?

smmBusinessRelationsListPage is (as the name says) a list page, which uses a query as its data source. That means that you can't overwrite the active method of the tables in the data source. Instead take a look at the interaction class of the list page, smmBusinessRelationsListPageInteraction (which is defined in the InteractionClass property of the root node of the form). This class already overwrites the selectionChanged method of its parent and this is the place where you would check for the state of the checkbox field.
