This widget represents a scale (numeric or date-time) and two sliders. A user selects the required range by moving the sliders.

RangeSelector

You can create the widget using one of the following approaches.

  • jQuery

    HTML
    <div id="rangeSelector"></div>
    JavaScript
    $(function() {
        $("#rangeSelector").dxRangeSelector({
            scale: {
                startValue: new Date(2011, 0, 1),
                endValue: new Date(2011, 5, 1),
                tickInterval: { days: 7 }
            }
        });
    });
  • AngularJS

    HTML
    <div ng-controller="DemoController">
        <div dx-range-selector="{
            scale: {
                startValue: startDate,
                endValue: endDate,
                tickInterval: { days: 7 }
            }
        }"></div>
    </div>
    JavaScript
    angular.module('DemoApp', ['dx'])
        .controller("DemoController", function ($scope) {
            $scope.startDate = new Date(2011, 0, 1);
            $scope.endDate = new Date(2011, 5, 1);
        });
  • Knockout

    HTML
    <div data-bind="dxRangeSelector: {
        scale: {
            startValue: new Date(2011, 0, 1),
            endValue: new Date(2011, 5, 1),
            tickInterval: { days: 7 }
        }
    }"></div>
  • ASP.NET MVC Wrappers

    Razor C#
    Razor VB
    @(Html.DevExtreme().RangeSelector()
        .ID("rangeSelector")
        .Scale(scale => scale
            .StartValue(new DateTime(2011, 1, 1))
            .EndValue(new DateTime(2011, 6, 1))
            .TickInterval(ti => ti.Days(7))
        )
    )
    @(Html.DevExtreme().RangeSelector() _
        .ID("rangeSelector") _
        .Scale(Sub(scale)
            scale.StartValue(New DateTime(2011, 1, 1)) _
                 .EndValue(New DateTime(2011, 6, 1)) _
                 .TickInterval(Sub(ti) ti.Days(7))
        End Sub)
    )

Note that DevExtreme widgets require you to link the jQuery library to your application. If you use the Knockout or AngularJS approach, the Knockout or AngularJS library is also required. For detailed information on linking these libraries to your project, refer to the topics in the Installation section.

A chart can be displayed in the background of the RangeSelector widget. This allows end users to select the required range in a chart series. You can also integrate the RangeSelector widget with a stand-alone Chart widget to emulate chart zooming and scrolling.

Configuration

An object that defines configuration options for the RangeSelector widget.

Show Example:
jQuery

This example shows how to display the RangeSelector widget. The only option which is specifically set is the dataSource. The other option - the dataSourceField - thought required, does not have to be specified because it is set to 'arg' (a required data source field) by default.
