[Solved] How to get the properties of applied sort

[ilker]

Hello,

My grid has a column that displays the index of rows as below. I am trying to enumerate these index numbers from 1 to n or from n to 1, according to sorting direction of column.

How can I detect the direction of applied sort, so that i can set the index on onDataBinding event and also apply ++index or --index according to sort direction? Numbers should be from 1 to n, when sorted asc; and from n to 1 when sorted desc.

<script type="text/javascript">
    var index = 0;

    function onDataBinding(){
        var grid = $("#grdInvoiceItems").data('tGrid');
        index = (grid.currentPage -1) * grid.pageSize; //Sorting  like 1,2,3,4.. (by ++index)
        index = ('@ViewBag.TotalRows');  //Sorting  like 10,9,8,7.. (by --index)
    }
</script>
@{
   ...
        columns.Bound(m => m.RecordPosition).Width(10).HtmlAttributes(new { nowrap = "nowrap" })
            .ClientTemplate(@"<#= ++index #>").Title("#").Filterable(false);
     ...
    .EnableCustomBinding(true)
    .DataBinding(dataBinding => dataBinding.Ajax().Select("_GetInvoiceItems", (string)ViewBag.Controller))
    .ClientEvents(e => e.OnDataBinding("onDataBinding"))
    .Sortable(s => s.OrderBy(sortOrder => sortOrder.Add(m => m.RecordPosition).Ascending())
                    .SortMode(GridSortMode.MultipleColumn)
)
    .Filterable();

    fl.Render();
}

Thanks,

Ilker.
