Remarks

A Bootstrap Range Selector control is displayed as a one-dimensional scale with two sliders. An end-user selects the required range by moving the sliders.

You can configure the following control settings.

• BootstrapRangeSelector.SettingsScale - Specifies the scale options.
• BootstrapRangeSelector.Chart - Specifies the options required to display a chart as the range selector’s background.
• BootstrapRangeSelector.SettingsSliderMarker - Defines the slider markers’ settings.
• BootstrapRangeSelector.SettingsBehavior - Specifies the control’s behavior options.
• BootstrapRangeSelector.SettingsBackground - Defines the range selector’s background settings.
• BootstrapRangeSelector.Value - Specifies the control’s current value. The client-side alternative is the BootstrapClientRangeSelector.GetValue method. To run the required code once the control’s value is changed, handle the BootstrapRangeSelector.ValueChanged event.

Note

The Bootstrap Range Selector control provides you with a comprehensive client-side functionality implemented using JavaScript code:

• The control’s client-side equivalent is represented by the BootstrapClientRangeSelector object.
• On the client side, the client object can be accessed directly by the name specified via the BootstrapRangeSelector.ClientInstanceName property.
• The available client events can be accessed by using the BootstrapRangeSelector.ClientSideEvents property.

Example

The following example demonstrates the Bootstrap Range Selector control’s functionality with a chart in the background. Follow the steps below to bind the control to the required data source and set up the control appearance.

1. Set the data source using either the BootstrapWebClientUIWidget.DataSourceUrl or the BootstrapWebClientUIWidget.DataSourceID property. To get more information, refer to the Binding to Data topic.
2. Assign the name of the data source field that stores scale values to the BootstrapChartCommonSeriesBase.ArgumentField property.
3. Create chart series (the BootstrapChartSplineSeries type is used in this example) and specify the data source field - BootstrapChartSeries.ValueField - for each series.

The image below shows the result.

C#

<dx:BootstrapRangeSelector runat="server" DataSourceUrl="~/Content/productweight.json" TitleText="Select a Product Weight" >
    <Chart>
        <SettingsCommonSeries ArgumentField="weight" />
        <SeriesCollection>
            <dx:BootstrapChartSplineSeries ValueField="appleCost" >
            </dx:BootstrapChartSplineSeries>
            <dx:BootstrapChartSplineSeries ValueField="orangeCost" >
            </dx:BootstrapChartSplineSeries>
        </SeriesCollection>
    </Chart>
</dx:BootstrapRangeSelector>
