2 |
No tables or the controls bound to their fields can be edited. |
Note: If you don't want data in bound controls to be edited when a form is in Form view or Datasheet view, you can set the RecordsetType property to Snapshot.
The RecordsetType property uses the following settings in a Microsoft Access project (.adp).

(Default) All tables and controls bound to their fields can be edited. |
Note: You can set this property by using a form's property sheet, a macro, or Visual Basic for Applications (VBA) code.
Note: Changing the RecordsetType property of an open form or report causes an automatic recreation of the recordset.
You can create forms based on multiple underlying tables with fields bound to controls on the forms. Depending on the RecordsetType property setting, you can limit which of these bound controls can be edited.
In addition to the editing control provided by RecordsetType, each control on a form has a Locked property that you can set to specify whether the control and its underlying data can be edited. If the Locked property is set to Yes, you can't edit the data.
Example
In the following example, only if the user ID is ADMIN can records be updated. This code sample sets the RecordsetType property to Snapshot if the public variable gstrUserID value is not ADMIN.
Sub Form_Open(Cancel As Integer) Const conSnapshot = 2 If gstrUserID <> "ADMIN" Then Forms!Employees.RecordsetType = conSnapshot End IfEnd Sub
