I have a problem with a bound textbox. The field is required and don’t allow Null in the database.

This gives me a problem when I want to clear the textbox. For example if I entered something and deleted it then the validation rule kicks in and don’t allow me to leave the field. I can only leave the field if I hit ESC so reset it to its original (unaltered) state.

I tried setting the field to Nothing and DefaultValue in an _After-/_BeforeUpdate() event but that doesn’t work.

Thank you for your help.

    The way I ended up solving this, thanks to the comments, was using an unbound textbox and then copying the validation rule from the database in the form On Load procedure.

    Private Sub Form_Load()
    Me.MyTextbox.ValidationRule = CurrentDb.TableDefs("SomeTable").Fields("SomeColumn").ValidationRule & " Or Is Null"
    Me.MyTextbox.ValidationText = CurrentDb.TableDefs("SomeTable").Fields("SomeColumn").ValidationText
End Sub

    Note I added “Or Is Null” to the rule else I would be stuck in the textbox if I deleted my input.
    The validation rule in the database is: >=1 And <=10

    Hope this helps someone 🙂
