title: How to count the records in a RadGrid? (Client-side, AJAX)
body: <p>I have a grid declaratively bound to a SQL data source. I then filter this grid and filtered results are displayed. I also have a label which displays a message like "17 records with current filters.".</p>
  
  <p>What RadGrid event would I handle to update my label to display this message with an up-to-date count of the number of records displayed in the RadGrid?a</p>
  
  <p>My grid uses Ajax to update the records based on filters.</p>
