Navigator appearance

The navigator can be customized using the NavigatorStyleSettings property. The SelectedRegionColor property is used to specify the color for selected region whereas the UnSelectedRegionColor property is used to specify the color for unselected region.

@using Syncfusion.EJ2.Blazor.Charts

<EjsRangeNavigator Value="@Value">
    <RangeNavigatorRangeTooltipSettings Enable="true"></RangeNavigatorRangeTooltipSettings>

    <RangeNavigatorStyleSettings UnselectedRegionColor="skyblue" SelectedRegionColor="pink"></RangeNavigatorStyleSettings>

    <RangeNavigatorSeriesCollection>
        <RangeNavigatorSeries DataSource="@StockDetails" XName="Date" Type="RangeNavigatorType.Area" 
                              YName="Close" ></RangeNavigatorSeries>
    </RangeNavigatorSeriesCollection>
</EjsRangeNavigator>

@code{

    int[] Value = new int[] { 45, 78 };

    public class Data
    {
        public double Date;
        public double Close;
    }

    public List<Data> StockDetails = new List<Data>
    {
        new Data {  Date = 12, Close = 28 },
        new Data {  Date = 34, Close = 44 },
        new Data {  Date = 45, Close = 48 },
        new Data {  Date = 56, Close = 50 },
        new Data {  Date = 67, Close = 66 },
        new Data {  Date = 78, Close = 78 },

Deferred update

If the EnableDeferredUpdate property is set to true, then the changed event will be fired after dragging the slider. If the EnableDeferredUpdate is false, then the changed event will be fired when dragging the slider. By default, the EnableDeferredUpdate is set to false.

Allow snapping

The AllowSnapping property toggles the placement of the slider exactly to the left or on the nearest interval.

snap.razor

@using Syncfusion.EJ2.Blazor.Charts

<EjsRangeNavigator Value="@Value" AllowSnapping="true">
    <RangeNavigatorRangeTooltipSettings Enable="true"></RangeNavigatorRangeTooltipSettings>

    <RangeNavigatorSeriesCollection>
        <RangeNavigatorSeries DataSource="@StockDetails" XName="Date" Type="RangeNavigatorType.Area" 
                              YName="Close"></RangeNavigatorSeries>
    </RangeNavigatorSeriesCollection>
</EjsRangeNavigator>

@code{

    int[] Value = new int[] { 45, 78 };

    public class Data
    {
        public double Date;
        public double Close;
    }

    public List<Data> StockDetails = new List<Data>
    {
        new Data {  Date = 12, Close = 28 },
        new Data {  Date = 34, Close = 44 },
        new Data {  Date = 45, Close = 48 },
        new Data {  Date = 56, Close = 50 },
        new Data {  Date = 67, Close = 66 },
        new Data {  Date = 78, Close = 78 },
        new Data {  Date = 89, Close = 84 },
    };

                              YName="Close"></RangeNavigatorSeries>
    </RangeNavigatorSeriesCollection>
</EjsRangeNavigator>

@code{
