The Events tab page, allows you to assign a macro to certain events which occur in a form.
To link an event with a macro, first write a macro that contains all the commands to be executed when the event happens. Then assign this macro to the respective event by clicking the ... button beside the corresponding event. The Assign Macro dialog opens, where you can select the macro.
The following actions can be configured individually, meaning that you can use your own dialogs to depict an action:
Displaying an error message,
Confirming a delete process (for data records),
Checking input when saving a data record.
For example, you can issue a "confirm deletion" request such as "Really delete customer xyz?" when deleting a data record.
The events that are shown in the Events dialog cannot be edited directly. You can delete an event from the list by pressing the Del key.
The following lists and describes all events in a form that can be linked to a macro:
The Before update event occurs before the control content changed by the user is written into the data source. The linked macro can, for example, prevent this action by returning "FALSE".
The After update event occurs after the control content changed by the user has been written into the data source.
ફરી સુયાેજિત કરવાને પ્રાધાન્ય આપો
The Prior to reset event occurs before a form is reset. The linked macro can, for example, prevent this action by returning "FALSE".
A form is reset if one of the following conditions is met:
The user presses an (HTML) button that is defined as a reset button.
A new and empty record is created in a form that is linked to a data source. For example, in the last record, the Next Record button may be pressed.
The After resetting event occurs after a form has been reset.
જ્યારે ફરી લાવી રહ્યા છે ત્યારે
The When reloading event occurs directly after the form has been reloaded. The data content has already been refreshed.
જ્યારે લાવી રહ્યા છે ત્યારે
The When loading event occurs directly after the form has been loaded.
જ્યારે લાવ્યા ન હોય ત્યારે
The When unloading event occurs directly after the form has been unloaded; that is, separated from its data source.
દૂર કરવાની ખાતરી
The Confirm deletion event occurs as soon as data has been deleted from the form. For example, the linked macro can request confirmation in a dialog.
The Fill parameters event occurs when the form to be loaded has parameters that must be filled out. For example, the data source of the form can be the following SQL command:
SELECT * FROM address WHERE name=:name
Here :name is a parameter that must be filled out when loading. The parameter is automatically filled out from the parent form if possible. If the parameter cannot be filled out, this event is called and a linked macro can fill out the parameter.
The Error occurred event is activated if an error occurs when accessing the data source. This applies to forms, list boxes and combo boxes.

The After record change event occurs directly after the current record pointer has been changed.
