  Hello,

  I am using FlexGrid and Selector (wijmo.grid.selector).
  
  I met a problem in grid client-side paging.
  
  For instance, I have 10 records in the first page and 3 records are selected.
  
  When I move to the second page and then go back to the first page, the 3 records in the first page are not selected any more.

  Are there any methods to keep rows selected after paging?

  Thanks in advance!

  Hi Wang,

  I apologize for the delay in response. Unfortunately, there is no method in-built into the grid to save the selectedItems. Instead, you will need to use the Map object to save the selected items. You can use the pageChanging/pageChanged events of CollectionView class to save/restore the items.
  
  Please refer to the sample link below for reference:
