title: How to count Number of Rows devexpress xtragrid
body: <p>I am using Devexpress XtraGrid Control, Here I can count the number of rows in footer of grid. but for this I need to set count property of SummeryItem in grid for at least one column. I dont want to do like this.</p>
  
  <p>I want count number of rows in xtraGrid without referring any one column in grid. I just want to show number of rows count. when user will filter that rows, at that time count also need to be changed.</p>
  
  <p>Is there any option to show this number in Group header panel?</p>
