title: Update multiple rows in datatable without loop
body: <p>I have two datatable with conditions in application and want some processing for multiple rows to update column value.</p>
  
  <p>For example:</p>
  
  <p>I have datatable1 with 10000 rows. I want to filter rows by datatable.select("condition") and as per condition, I want to update row values.</p>
  
  <p>If for any condition, I found 20 rows from datatable. I want to update those 20 records in one shot. Not in any loop. I have datarow array for those values to update in datable.</p>
