title: How to generate new number when you generate new record?
body: <p>I have a task. Task where I need to generate number when load new loading list. I did a formular in which is field called "LoadingListNumber". What I need is generate this number in format: 04/0001/19 (Month/LoadingListNumber/Year). The number 0001 is loaded when its new record. So if you have new record it will be 0001, another record 0002,0010 etc. I know how to generate the month and year, but not this number :/ </p>
  
  <p>I have already generated month in this sentence and year.</p>
  
  <pre><code>NumberOfLoadingList = string.Format(DateTime.Now.ToString("MM") + "/" + DateTime.Now.Year.ToString("YY"));
  </code></pre>
  
  <p>I really need a tip or advice, how to generate the number. Thank you.</p>
