You would not normally need to "refresh" a form after updating a single control, that control would normally display the value you entered.

However, if you are dealing with some form of cascading controls (where one list or combo box depends on the value of another), then you might try something like:

Private Sub cboOne_AfterUpdate

    me.cbo_Two.Requery

    'if you have more than one other control that is dependent, or cbo_Three 
    'is dependent upon cbo_Two then you would also need to requery that control
    me.cbo_Three.Requery

End Sub

Open in new window

Then you would requery cbo_Three in the AfterUpdate of cbo_Two.

IF ... you attempt to do this in the AU of a Control ... and the Form is Dirty (in edit mode) ... Access will at that moment attempt to Save your record - which is likely NOT desired at that moment.

Instead ... if necessary ... use the Form AfterUpdate event to do this ...
either
Me.Requery
or
Me.Refresh

depending on what you are trying to accomplish.

Hi Dale,,,

That is to say: there is nothing like "Refresh Form".   Correct Me Pls.
There are two options:

Me.Refresh  ' Refreshes the current existing dataset - but no new records other may have added

Me.Requery ' Refreshes entire recordsource, including any new records that may have been added.

That's it :-)
As Joe indicates, you could use me.Refresh  but all that would refresh the recordset and overwrite your changes.

If you want to write that changed value to the table, then you need:

Me.Dirty = False

The Dirty property of the form gets set to True when the value of any control on the current record changes.  To actually write that data to the table, you must save the record  which can be done in a variety of ways:

1.  move off the record
2.  Docmd.RunCommand acCmdSave
3.  Me.Dirty = false

#1 occurs automatically if you move off the current record or click on a control that is in a parent or subform.

HTH

"but all that would refresh the recordset and overwrite your changes."
Not after the record has been saved ...
Joe,

The OP didn't say the record was saved.  the question was (emphasis mine):
