  Hi,

  I can not decide, use DisableServerRead good idea or not.

  For example, I have table with 1000 000 items.
  
  In FlexGrid I used many client-side operations: save states, quick search…
  
  http://demos.componentone.com/aspnet/ASPNetMVCCollectionView101

  If DisableServerRead = true, then table loaded about 1,5 minutes.

  If DisableServerRead = false, then my table loaded about 15 seconds.
  
  But some client-side operations require DisableServerRead = true,
  
  and also when i restore grid state with

  
  collectionView.sortDescriptions 
  itemsSource.pageSize
  filter.filterDefinition
  
  

  each of them initiate request on server.

  That will be more correct?

  The problem is that there is a choice between long loading if DisableServerRead = true, or multiple requests to the server when restoring the saved state and refusing some functionality.
  
  Both choices are not very good

  Hi Alex,

  I get it. There are some unavoidable drawbacks of using multiple requests. For your case, I would suggest you use client side virtualization.

  See example here:

  I compete my task by next solution.
  
  I use DisableServerRead = false.
  
  Grid state save in localStorage as before. But use special block

  
  
  flex.collectionView._disableServerRead = true; 
  
  ... // restore state
  
  flex.collectionView._disableServerRead = false;
  flex.collectionView.refresh();
  
  

  In this way, when you restore a state, there will be only one request to the server.
