SUMMARY

You can create default events for your User Controls. A default event is the event selected when you double-click on the control in Design Mode. For example, when you double-click on a CommandButton, the code window creates a Sub-procedure for Command_Click. Therefore, click is the default event for the CommandButton. This article will explain how to create a default event for a User Control that you create.

MORE INFORMATION

To create a default event, first you must create the event by doing the following:

  1. From the Tools menu, select "Add Procedure."

  2. In the "Add Procedure" dialog box, enter the Event name, and check the Event option in the Type frame.

  3. Click the OK button.

NOTE: You must use the RaiseEvent command to actually trigger your event while the User Control is in use. Creating an event simply creates an event: it does not add any code that causes the event to occur.

After the event is created, follow these steps to make the event the default event:

  1. From the Tools menu, select "Procedure Attributes."

  2. In the "Procedure Attributes" dialog box, select the event name you previously entered.

  3. Add a Description, if desired, and select the "Advanced>>" button.

  4. Select the "User Interface Default" checkbox in the Attributes frame.

When using the User Control in a Visual Basic form, double-clicking on the Control will create a procedure for the Event you specified.

You can only have one default Event for each Control. Therefore, you can only select the "User Interface Default" checkbox for one event. If you select this checkbox for another event, it will ask you if you want to make the newly-selected event the Default event.
