title: How to set pageSizes after kendo grid is initialized?
body: <p>I am basicly trying to set an "All Items"-Pagesize to kendo grid. I know I can get the total items this way:</p>
  
  <pre><code>var grid = $("#CardGrid").data("kendoGrid");
  var dataSource = grid.dataSource;
  dataSource.fetch(function () {
      alert(dataSource.total());
  });
  </code></pre>
  
  <p>This is the reason I am trying to set the pagesize after the grid is initialized:</p>
  
  <pre><code>var grid = $("#CardGrid").data("kendoGrid");
  console.debug(grid.options);
  grid.options.pageable.pageSizes = [10, 25, 50, 100]; //This does not affect the combobox for the pagesizes
  </code></pre>
  
  <p>So how can I set the pagesizes?</p>
