Set initial filter on a boolean field column on load - kendo-grid

Question

Telerik Kendo MVC Grid - How do I set onload/initial filter equals True with checkbox columns?
I am trying to set a True/False column filter to True on initial load. My Viewmodel has a bool property called IsHoliday. I have followed the example in the link above but i don't have any records showing in the grid at startup. My read action returns a JSON of IEnumerable as suggested in the referenced link. My View is as follows:
#(Html.Kendo().Grid<HolidayVM>()
.Name("h_grid")
.Editable(editable => editable.Mode(GridEditMode.PopUp))
.DataSource(dataSource => dataSource
.Ajax()
.PageSize(15)
.ServerOperation(false)
.Events(events => events.Error("grid_error")) // Handle the "error" event
.Model(model =>
{
model.Id(m => m.Date);
model.Field(m => m.Date).Editable(false);
})
.Filter(f => f.Add(m => m.IsHoliday.Equals(true)))
.Read(read => read.Action("Holiday_Read", "Holiday"))
.Update(up => up.Action("Holiday_Update", "Holiday").Data("grid_sendAntiForgery"))
)
.Columns(columns =>
{
columns.Bound(p => p.Date).Width(30).Format("{0:dd-MMMM}");
columns.Bound(p => p.HolidayText).Width(100).Filterable(false);
columns.Bound(p => p.IsHoliday)
.ClientTemplate("<input type='checkbox' #= IsHoliday ? '' : checked='checked' # disabled='disabled' />")
.Filterable(ftb => ftb.Cell(cell => cell.Operator("Is equal to")))
.Width(30);
columns.Command(cmd =>
{
cmd.Edit().HtmlAttributes(new { title = "Edit" });
}).Title("Commands").Width(25);
})
.Pageable()
.Sortable()
)
Ideally I will like my grid to look like in attached image, on load, with IsHoliday set to True

Answer 1

I finally figured it out.
.Filter(f => f.Add(m => m.IsHoliday).IsEqualTo(true))
instead of
.Filter(f => f.Add(m => m.IsHoliday.Equals(true)))

Answer 2

use this easily:
columns.Bound(p => p.ISProperty).ClientTemplate("#= ISProperty? 'Yes' : 'No' #")
