You basically need to define a filter for your DataSource and then invoke filter method.
This is done as follows:
// Get from date in this case we read it from an input DatePicker
var from = $("#from").data("kendoDatePicker").value()
// Get to date in this case we read it from an input DatePicker
var to = $("#to").data("kendoDatePicker").value()
// Create a filters condition. By default, the conditions are "and" but they might also
// be "or"
var filters = [
{field: "BirthDate", operator: "gte", value: from},
{field: "BirthDate", operator: "lte", value: to}
];
// Set the filtering condition to our grid dataSource
grid.dataSource.filter(filter);

You can also do it defining the input fields for dates in the Grid toolbar if you want to display them permanently.
Defining the template:
<script id="dates-template" type="text/kendo-tmpl">
From: <input id="from" style="width: 120px"/>
To: <input id="to" style="width: 120px"/>
<button id="filter" class="k-button">Filter</button>
</script>
And adding to your grid initialization the toolbar template defined above:
var grid = $("#grid").kendoGrid({
toolbar : [
{ template: kendo.template($("#dates-template").html()) }
],
dataSource: ds,
