title: Radgrid stop editing but allow paging
body: <p>I need a way to stop all editing (insert, update, delete) on a Radgrid but still allow the paging to work.</p>
  
  <p>Ive tried disabling the MasterTableView but this also stops my users from viewing the data.</p>
  
  <p>The only way I can see to do it, is to check if they are allowed to edit in the various handlers for the insert, update and delete commands and take action in there.</p>
  
  <p>It would be nicer to somehow disable the command columns if the user does not have access.</p>
