Form.SubdatasheetExpanded Property (Access)
You can use the SubdatasheetExpanded property to specify or determine the saved state of all subdatasheets within a table or query. Read/write Boolean.
Syntax
expression .SubdatasheetExpanded
expression A variable that represents a Form object.
Remarks
The default value is False.
To set the SubdatasheetExpanded property by using Visual Basic, you must first create the property by using the DAO CreateProperty method.
The SubdatasheetExpanded and SubdatasheetHeight properties take effect on the subform control when the form is in datasheet view.
Example
The following example turns subdatasheet expansion on or off for the "Purchase Orders" form.
To try this example yourself, open a form (containing a subform) in Design view, click the Builder button next to the On Load property box in the form's property window, paste this code into the form's Form_Load event (removing the reference to the "Purchase Orders" form), and then open the form in Datasheet view.
Dim strExpand As String
With Forms("Purchase Orders")
strExpand = InputBox("Expand subdatasheets? Y/N")
Select Case strExpand
Case "Y"
.SubdatasheetExpanded = True
Case "N"
.SubdatasheetExpanded = False
Case Else
MsgBox "Can't determine subdatasheet expansion state."
End Select
End With
