allowPaging: true,

allowSorting: true,

allowFiltering: true,

filterSettings:{filterType:"filterbar", filterBarMode: ej.Grid.FilterBarMode.OnEnter},

columns: [

{ field: "OrderID", headerText: "Order ID", textAlign: ej.TextAlign.Right, width: 90 },

{ field: "OrderDate",type:"date", headerText: "Order Date", width: 200, format:"{0:dd-MMM-yyyy}"},

{ field: "CustomerID", headerText: "Customer ID", width: 100 },
