    function resetRowNumber(e) {
        rowNumber = 0;
    }

    function renderNumber(data) {
        return ++rowNumber;
    }

    function renderRecordNumber(data) {
        var page = parseInt($("#Grid").data("kendoGrid").dataSource.page()) - 1;
        var pagesize = $("#Grid").data("kendoGrid").dataSource.pageSize();
        return parseInt(rowNumber + (parseInt(page) * parseInt(pagesize)));

             columns.Bound(p => p.ID); 
             columns.Bound(p => p.Name); 
             columns.Template(t => { }).Title("Row No").ClientTemplate( "#= renderNumber(data) #" ); 
             columns.Template(t => { }).Title("Record No").ClientTemplate( "#= renderRecordNumber(data) #" ); 
         }) 
.Pageable(x => x.PageSizes(new int[] { 10, 20, 30, 50 }).Refresh(true)) 
.Sortable() 
.Filterable() 
.DataSource(dataSource => dataSource.Ajax()
            .Read(read => read.Action("Grid_Read", "Home")) 
            )

        var pagesize = $("#Grid").data("kendoGrid").dataSource.pageSize();
        return parseInt(rowNumber + (parseInt(page) * parseInt(pagesize)));
    }

    $(document).ready(function () {

        $("#Grid").kendoGrid({
