In Modify Selected Toolbar Action, Column? when Source is not ID, what does entering a display column do?

• A. The row will be exported to a file.
• B. The column's value will be sent to the activity this button calls.
• C. The column's name will be used as the activity endpoint.
• D. The results will be exported to a file.

Answer: (B)

This tests how a value from the grid row is passed into the action that the button triggers. When the Source isn’t an ID and you enter a display column, the value shown in that column for the current row becomes the parameter sent to the activity the button calls. In other words, each row provides its own value for that parameter, and that value is handed off to the backend action. The other options describe exporting data or using a column name as an endpoint, which isn’t what happens here—the display column simply feeds the activity with the row’s column value.
