VALIDATION_MESSAGE
= optional for each custom button
A custom button can be defined to first show a confirmation dialog before the actual custom button function is executed.
To include a confirmation message when a user clicks the Custom button from the ribbon, add a message in the Confirmation Message field in the Add New or Edit Custom Button dialog, shown below:
When the right panel is collapsed, the information added in the above dialog will be automatically written to the SCRIPTS worksheet, and the VALIDATION_MESSAGE property for the specific button will be updated.
A dialog will first appear, prompting the user to confirm the action. The confirmation message text specified in template design is shown as text in the dialog.
If user clicks Yes, then the function linked to the button will be executed. If user clicks No, no action will be executed.
