Solution

This can be achieved using the CustomDrawEventHandler as shown below

Private Sub CustomDrawEventHandler(. ByVal .. As )

        If IsError(...) Then

            e.EditViewInfo.ErrorIconText = "IsNull"

            e.EditViewInfo.ShowErrorIcon = True

            e.EditViewInfo.FillBackground = True

            e.EditViewInfo.ErrorIcon = DXErrorProvider.GetErrorIconInternal(ErrorType.Critical)

            e.EditViewInfo.CalcViewInfo(e.Graphics)

        End If

End Sub
