export dhtml xgrid to an excel

could you please help me how to export from xgrid to excel…

There is no cross browser way to export data directly in excell
You can

a) serialize data into CSV, which can be imported into ms-excel
    var data=grid.serializeToCSV();
( please beware that you will need to send data to server and back to client, to allow saving it as file )

b) use MS-IE specific solution
