title: Telerik RadGrid getDataItems() not working when paging is enabled
body: <p>I am trying to delete all rows on telerik radgrid  from the client-side. I can get this delete function to work but only when paging is disabled, otherwise when paging is enabled it just deletes the first page every time.</p>
  
  <p>Is there a way that I can get this to work or there is a different approach?</p>
  
  <p>Here is my callback when a button to delete all rows is pressed:</p>
  
  <pre><code>function DeleteDialogCallBack(args) {
              if (args === true) {
                  var ajaxManager = $find("&lt;%= MasterUserListRadAjaxManager.ClientID %&gt;");
                  var grid = $find("&lt;%= UserMasterListRadGrid.ClientID %&gt;");
                  var masterTable = grid.get_masterTableView();
                  var selectedRows = masterTable.get_selectedItems();
  
                  var param = "Delete";
  
                  for (var i = 0; i &lt; selectedRows.length; i++) {
                      var row = selectedRows[i];
                      param += "|" + masterTable.getCellByColumnUniqueName(row, "ID").innerHTML;
                  }
  
                  ajaxManager.ajaxRequest(param);
              }
          }
  </code></pre>
  
  <p>Thank you</p>
