Customization in ASP.NET MVC Range Navigator control

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.

razor
appearance.cs
@(Html.EJS().RangeNavigator("container")
                    .ValueType(Syncfusion.EJ2.Charts.RangeValueType.DateTime)
                    .LabelFormat("{value}K")
                .NavigatorStyleSettings( style => {
                    style.unselectedRegionColor("Skyblue").selectedRegionColor("black")
                })
                .Series(sr =>
                {
                    sr.XName("x").YName("y").DataSource(ViewBag.dataSource).Add();
                }).Render()
                )
public IActionResult Index()
        {
            List <data> dataSource = new List<data>
            {
                new data {  y = 12, y1 = 28 },
                new data {  y = 34, y1 = 44 },
                new data {  y = 45, y1 = 48 },
                new data {  y = 56, y1 = 50 },
                new data {  y = 67, y1 = 66 },
                new data {  y = 78, y1 = 78 },
                new data {  y = 89, y1 = 84 },
            };
            ViewBag.dataSource = dataSource;
            return View();
        }
        public class data
        {
            public double y;
            public double y1;
        }

Thumb

The thumb property provides options to customize the border, fill, size, and type of thumb. The types of thumb can be “Circle” and “Rectangle”.

razor
thumb.cs
@(Html.EJS().RangeNavigator("container")
                    .ValueType(Syncfusion.EJ2.Charts.RangeValueType.DateTime)
                    .LabelFormat("{value}K")
                    .NavigatorStyleSettings( style => {
                    style.unselectedRegionColor("Skyblue").selectedRegionColor("black").Thumb("ViewBag.thumb)
                })
                .Series(sr =>
                {
                    sr.XName("x").YName("y").DataSource(ViewBag.dataSource).Add();
                }).Render()
                )
public IActionResult Index()
        {
            List <data> dataSource = new List<data>
            {
                new data {  y = 12, y1 = 28 },
                new data {  y = 34, y1 = 44 },
                new data {  y = 45, y1 = 48 },
                new data {  y = 56, y1 = 50 },
                new data {  y = 67, y1 = 66 },
                new data {  y = 78, y1 = 78 },
                new data {  y = 89, y1 = 84 },
            };
            ViewBag.dataSource = dataSource;
            return View();
        }
        public class data
        {
            public double y;
            public double y1;
        }

Border customization

Using the “navigatorBorder” property, you can customize the “width” and “color” of the range navigator.

razor
border.cs
@(Html.EJS().RangeNavigator("container")
                    .ValueType(Syncfusion.EJ2.Charts.RangeValueType.DateTime)
                    .LabelFormat("{value}K")
                    .NavigatorBorder("ViewBag.border")
                .Series(sr =>
                {
                    sr.XName("x").YName("y").DataSource(ViewBag.dataSource).Add();
                }).Render()
                )
public IActionResult Index()
        {
            List <data> dataSource = new List<data>
            {
                new data {  y = 12, y1 = 28 },
                new data {  y = 34, y1 = 44 },
                new data {  y = 45, y1 = 48 },
                new data {  y = 56, y1 = 50 },
                new data {  y = 67, y1 = 66 },
                new data {  y = 78, y1 = 78 },
                new data {  y = 89, y1 = 84 },
            };
            ViewBag.dataSource = dataSource;
            return View();
        }
        public class data
        {
            public double y;
            public double y1;
        }

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.

razor
@(Html.EJS().RangeNavigator("container")
                    .ValueType(Syncfusion.EJ2.Charts.RangeValueType.DateTime)
                    .LabelFormat("{value}K")
                    .EnableDeferredUpdate(true)
                })
                .Series(sr =>
                {
                    sr.XName("x").YName("y").DataSource(ViewBag.dataSource).Add();
                }).Render()
                )

Allow snapping

The “allowSnapping” property toggles the placement of the slider exactly to the left or on the nearest interval.

razor
snap.cs
@(Html.EJS().RangeNavigator("container")
                    .ValueType(Syncfusion.EJ2.Charts.RangeValueType.DateTime)
                    .LabelFormat("{value}K")
                    .AllowSnapping(true)
                })
                .Series(sr =>
                {
                    sr.XName("x").YName("y").DataSource(ViewBag.dataSource).Add();
                }).Render()
                )
public IActionResult Data()
        {
            List dataSource = new List
            {
                new data {  y = 12, y1 = 28 },
                new data {  y = 34, y1 = 44 },
                new data {  y = 45, y1 = 48 },
                new data {  y = 56, y1 = 50 },
                new data {  y = 67, y1 = 66 },
                new data {  y = 78, y1 = 78 },
                new data {  y = 89, y1 = 84 },
            };
            ViewBag.dataSource = chartData;
            return View();
        }
        public class data
        {            
            public double y;
            public double y1;
        }

Animation

The speed of the animation can be controlled using the “animationDuration” property. The default value of the “animationDuration” property is 500 milliseconds.

razor
animation.cs
@(Html.EJS().RangeNavigator("container")
                    .ValueType(Syncfusion.EJ2.Charts.RangeValueType.DateTime)
                    .LabelFormat("{value}K")
                    .AnimationDuration("2000")
                    .Series(sr =>
                    {
                    sr.XName("x").YName("y").DataSource(ViewBag.dataSource).Add();
                    }).Render()
                    )
public IActionResult Index()
        {
            List <data> dataSource = new List<data>
            {
                new data {  y = 12, y1 = 28 },
                new data {  y = 34, y1 = 44 },
                new data {  y = 45, y1 = 48 },
                new data {  y = 56, y1 = 50 },
                new data {  y = 67, y1 = 66 },
                new data {  y = 78, y1 = 78 },
                new data {  y = 89, y1 = 84 },
            };
            ViewBag.dataSource = dataSource;
            return View();
        }
        public class data
        {
            public double y;
            public double y1;
        }
