Datagrid while pagination true , disable reload button

[pratikk]

As written on subject ; In datagrid, I want to disable the reload button while pagination is set to true

[stworthy]

Please set 'showRefresh' property to false for the pagination to hide the 'refresh' button.

Code:

var pager = $('#dg').datagrid('getPager');
pager.pagination({showRefresh:false});

where do I have to put this code ?  
I am creating the datagrid in HTML.
 There is a function fires  on "body onload"   I put this code inside this function , but it is not working.
