title: How to set WPF Datagrid RowHeaderWidth to Auto?
body: <p>I have a datagrid in my application (WPF environment) to load data into it. 
  Row header in my app have row number in it (just like excel).
  Now my problem is when I have 99 rows, the width of row header is correct but when it is more than that rowheader width is too small and cuts the number (see the picture). I want to set rowheaderwidth to auto but there is no in-built command for that.any ideas? thanks for the help</p>
