You used a wrong property name 'remoteFiletr', please use 'remoteFilter' instead.

Code:

$('#approvalWorkLoadGrid').datagrid({
      remoteFilter: true,
      //...
});

I also have a question.when I add the attribute 'remoteFilter'.The datagrid can hardly be filtered In front .The datagrid always send a request to server with param 'filterRules'.Then I have to filter data backstage。pagination does work well.
when I not add the attribute 'remoteFilter'.The datagrid will not send a request to server ,but the pagination doesn't work.How can I solve this problem??
