title: Gridx: How to keep selections over multiple pages?
body: <p>I am currently encountering the following problem:</p>
  
  <p>I have a paged grid that consists of 5 pages. The user needs to select certain rows within that grid, while navigating through all of the 5 pages (some selections on page 1, some on page 2, etc.).</p>
  
  <p>How can I ensure that the user´s selection from page 1 won´t "disappear", once the user navigated on to another page?
  The way I currently have it set up, once the user clicks on page 2, the selections from page 1 are gone.</p>
  
  <p>Any help on this is highly appreciated. Thanks for your time.</p>
