AllowEdits Property

Applies to

Form Object

You can use the AllowEdits property to specify whether a user can edit saved records when using a form (form: An Access database object on which you place controls for taking actions or for entering, displaying, and editing data in fields.). Read/write Boolean.

expression.AllowEdits

expression Required. An expression that returns one of the objects in the Applies To list.

Setting

The AllowEdits property uses the following settings.

Setting Visual Basic Description
Yes True (Default) The user can edit saved records.
No False The user can't edit saved records.

You can set the AllowEdits property by using the form's property sheet (property sheet: A pane that is used to view or modify the properties of various objects such as tables, queries, fields, forms, reports, data access pages, and controls.), a macro (macro: An action or set of actions that you can use to automate tasks.), or Visual Basic for Applications (VBA) (Visual Basic for Applications (VBA): A macro-language version of Microsoft Visual Basic that is used to program Microsoft Windows-based applications and is included with several Microsoft programs.) code.

Remarks

You can use the AllowEdits property to prevent changes to existing data displayed by a form. If you want to prevent changes to data in a specific control, use the Enabled or Locked property.

If you want to prevent changes to existing records (make a form read-only), set the AllowAdditions, AllowDeletions, and AllowEdits properties to No. You can also make records read-only by setting the RecordsetType property to Snapshot.

Changing a field value programmatically causes the current record to be editable, regardless of the AllowEdits property setting. If you want to prevent the user from making changes to a record (AllowEdits is No) that you need to edit programmatically, save the record after any programmatic changes; the AllowEdits property setting will be honored once again after any unsaved changes to the current record are saved.

 Note   When the Data Mode argument of the OpenForm action is set, Microsoft Office Access 2007 will override a number of form property settings. If the Data Mode argument of the OpenForm action is set to Edit, Access will open the form with the following property settings:

  • AllowEdits — Yes
  • AllowDeletions — Yes
  • AllowAdditions — Yes
  • DataEntry — No

To prevent the OpenForm action from overriding any of these existing property settings, omit the Data Mode argument setting so that Access will use the property settings defined by the form.

Example

The following example examines the ControlType property for all controls on a form. For each label and text box control, the procedure toggles the SpecialEffect property for those controls. When the label controls' SpecialEffect property is set to Shadowed and the text box controls' SpecialEffect property is set to Normal and the AllowAdditions, AllowDeletions, and AllowEdits properties are all set to True, the intCanEdit variable is toggled to allow editing of the underlying data.
Sub ToggleControl(frm As Form)
    Dim ctl As Control
    Dim intI As Integer, intCanEdit As Integer
    Const conTransparent = 0
    Const conWhite = 16777215
    For Each ctl in frm.Controls
        With ctl
            Select Case .ControlType
                Case acLabel
                    If .SpecialEffect = acEffectShadow Then
                        .SpecialEffect = acEffectNormal
                        .BorderStyle = conTransparent
                        intCanEdit = True
                    Else
                        .SpecialEffect = acEffectShadow
                        intCanEdit = False
                    End If
                Case acTextBox
                    If .SpecialEffect = acEffectNormal Then
                        .SpecialEffect = acEffectSunken
                        .BackColor = conWhite
                    Else
                        .SpecialEffect = acEffectNormal
                        .BackColor = frm.Detail.BackColor
                    End If
            End Select
        End With
    Next ctl
    If intCanEdit = IFalse Then
        With frm
            .AllowAdditions = False
            .AllowDeletions = False
            . = False
        End With
    Else
        With frm
            .AllowAdditions = True
            .AllowDeletions = True
            . = True
        End With
    End If
End Sub
