[Solved] Grid loses orderBy on rebind

[Travis]

I'm using ajax to bind my grid and I have a default sortable expressions defined like so:

.Sortable(sorting => sorting.OrderBy(sortOrder => sortOrder.Add(o => o.DateCreated).Descending()))

I'm defining filter values on "OnDataBinding" like so:

function onDataBinding(e) {
    var filter = getFilter();
    e.data = filter;
}

When a drop down value is changed i'm rebining the grid, but for some reason the grid's sorting state is whiped out, i.e. the "orderBy" property of the grid is empty after doing a rebind.  So I have to reset it when rebinding like so:

function RebindGrid() {
        var grid = $('#Grid').data('tGrid');
        var sortOrder = grid.orderBy;
        grid.rebind({ orderBy: sortOrder });
        grid.orderBy = sortOrder;
    }

Why do I have to do this?  Shouldn't the grid remember its sorting expression on rebind?

Hello Travis,

 This behavior is expected and is by design. The rebind() method resets the grid state whereas ajaxRequest() doesn't. For more information on the subject, please check the following section in the documentation:

Ah, I see.  ajaxRequest() was what I needed.  Thank you!
