TextBox.OnKeyDown property (Access)
Sets or returns the value of the On Key Down box in the Properties window. Read/write String.
expression A variable that represents a TextBox object.
This property is helpful for programmatically changing the action that Microsoft Access takes when an event is triggered. For example, between event calls you may want to change an expression's parameters, or switch from an event procedure to an expression or macro, depending on the circumstances under which the event was triggered.
The KeyDown event occurs when a user presses a key while a form or control has the focus. This event also occurs if you send a keystroke to a form or control by using the SendKeys action in a macro or the SendKeys statement in Visual Basic.
The OnKeyDown value will be one of the following, depending on the selection chosen in the Choose Builder window (accessed by choosing the Build button next to the On Key Down box in the object's Properties window):
If you choose Expression Builder, the value will be =expression, where expression is the expression from the Expression Builder window.
If you choose Macro Builder, the value is the name of the macro.
If you choose Code Builder, the value will be [Event Procedure].
If the On Key Down box is blank, the property value is an empty string.
The following example prints the value of the OnKeyDown property in the Immediate window for the button named OK on the Order Entry form.
Debug.Print Forms("Order Entry").Controls("OK").OnKeyDown
