Getting Started with WPF Range Selector (SfDateTimeRangeNavigator)

Visual structure

The date-time range navigator control is composed of various elements such as higher level bar, lower Level bar, content, and resizable scroll bar.

  • Higher level bar: Contains timespan format that is one level higher than date-time values of lower level bar, e.g. the higher level bar contains year format (yyyy) and the lower level bar contains month format (MMM).
  • Lower level bar: Contains timespan format that is one lever lower than date-time values of higher level bar, e.g. the lower level bar contains month format (MMM) and the higher level bar contains year format (yyyy).
  • Content: Holds any type of UI element inside the navigator.
  • Resizable scroll bar: Allows users to zoom and scroll the content and label bars.

Create SfDateTimeRangeNavigator

The following section explains how to create SfDateTimeRangeNavigator.

Add the assembly reference

  1. Open the Add Reference window in your project.
  2. Choose our assemblies by following the given steps depending upon the developing environment.

    • If you use VS 2012, choose Assemblies > Extensions > Syncfusion.SfChart.WPF.dll.
    • If you use VS 2010, choose .Net > Syncfusion.SfChart.WPF.dll.
  3. Add the following namespace in your XAML page:
  • xaml
  • xmlns:Syncfusion="clr-namespace:Syncfusion.UI.Xaml.Charts"

    Initialize the SfDateTimeRangeNavigator

    <Syncfusion:SfDateTimeRangeNavigator>
    
    </Syncfusion:SfDateTimeRangeNavigator >
    SfDateTimeRangeNavigator rangeNavigator = new SfDateTimeRangeNavigator();

    Set ItemsSource for SfDateTimeRangeNavigator

    Since the above steps are enough to create only empty date-time range navigator, you need to set the ItemsSource and XBindingPath for the SfDateTimeRangeNavigator. The ItemsSource must implement the IEnumerable interface.

    <Syncfusion:SfDateTimeRangeNavigator ItemsSource="{Binding UsersList}" XBindingPath="Date"  >
    
    </Syncfusion:SfDateTimeRangeNavigator >
    SfDateTimeRangeNavigator rangeNavigator = new SfDateTimeRangeNavigator()
    {
    
            ItemsSource = new ViewModel().UsersList,
    
            XBindingPath ="Date"
    
    };

    Add content

    Add content that needs to be displayed inside the date-time range navigator.

    Property

    Property Description

    ItemsSource

    Sets the ItemsSource for SfDateTimeRangeNavigator.

    XBindingPath

    Represents the date-time x values.

    Content

    Adds any UI content inside the date-time range navigator.
    <Syncfusion:SfDateTimeRangeNavigator ItemsSource="{Binding UsersList}" XBindingPath="Date"  >
    
    	<Syncfusion:SfDateTimeRangeNavigator.Content>
    
    		<Syncfusion:SfChart x:Name="Chart">
    
    			<Syncfusion:SfChart.PrimaryAxis>
    
    				<Syncfusion:DateTimeAxis/>
    
    			</Syncfusion:SfChart.PrimaryAxis>
    
    		<Syncfusion:SfChart.SecondaryAxis>
    
        <Syncfusion:NumericalAxis/>
    
    </Syncfusion:SfChart.SecondaryAxis>
    
    <Syncfusion:LineSeries 
    
            ItemsSource="{Binding UsersList}" 
    
            XBindingPath="Date”
    
            YBindingPath="NoOfUsers">
    
    </Syncfusion:LineSeries>
    
    </Syncfusion:SfChart>
    
    </Syncfusion:SfDateTimeRangeNavigator.Content >
    
    </Syncfusion:SfDateTimeRangeNavigator >
    SfChart chart = new SfChart();
    
    chart.PrimaryAxis = new DateTimeAxis();
    
    chart.SecondaryAxis = new NumericalAxis();
    
    LineSeries series = new LineSeries()
    {
    
            ItemsSource = new ViewModel().UsersList,
    
            XBindingPath = "Date",
    
            YBindingPath = "NoOfUsers"
    
    };
    
    chart.Series.Add(series);
    
    SfDateTimeRangeNavigator rangeNavigator = new SfDateTimeRangeNavigator()
    {
    
            ItemsSource = new ViewModel().StockPriceDetails,
    
            XBindingPath ="Date"
    
    };
    
    rangeNavigator.Content = chart;

    The following screenshot illustrates the result of the above code sample.

    Create SfDateTimeRangeNavigator from code-behind

    This section explains how to create an application using the date-time range navigator from code-behind.

    Add assembly reference

    1. Open the Add Reference window in your project.
    2. Choose Windows > Extensions > Syncfusion.SfChart.WPF.
    3. Add the following namespace in your C# file: MainPage.xaml.cs.
  • c#
  • using Syncfusion.UI.Xaml.Charts;

    Initialize the Range Navigator

  • c#
  • SfDateTimeRangNavigator rangenavigator = new SfDateTimeRangNavigator ();

    Create a Sample Data Source

  • c#
  • public class ItemsSource
     {
    
       public DateTime Date { get; set; }
    
       public double NoOfUsers { get; set; }
    
     }
    
    public class UsersViewModel
    
     {
    
     public UsersViewModel()
    
      {
    
       this.UsersList = new ObservableCollection<ItemsSource>();
    
       DateTime date = DateTime.Today;
    
       UsersList.Add(new ItemsSource { TimeStamp = date.AddHours(0.5), NoOfUsers = 3000 });
    
       UsersList.Add(new ItemsSource { TimeStamp = date.AddHours(0.5), NoOfUsers = 5000 });
    
       UsersList.Add(new ItemsSource { TimeStamp = date.AddHours(0.5), NoOfUsers = 2000 });
    
       UsersList.Add(new ItemsSource { TimeStamp = date.AddHours(0.5), NoOfUsers = 7000 });
    
       UsersList.Add(new ItemsSource { TimeStamp = date.AddHours(0.5), NoOfUsers = 6000 });
    
       UsersList.Add(new ItemsSource { TimeStamp = date.AddHours(0.5), NoOfUsers = 3000 });  }
    
     public ObservableCollection<ItemsSource> UsersList
    
      {
    
        get; set;
    
      }
    
     }

    Define ItemsSource

    Define the ItemsSource for the date-time range navigator as demonstrated in the following code sample.

    NOTE

    You can set any IEnumerable collection as ItemsSource.

  • c#
  • //Intialize the SfDateTimeRangNavigator.
    
    SfDateTimeRangNavigator rangenavigator = new SfDateTimeRangNavigator ();
    
    rangenavigator.ItemsSource = UsersList;
    
    rangenavigator.XBindingPath = "Date";

    Add content

    Add the content that needs to be displayed inside the date-time range navigator control using the Content property.

  • c#
  • //Intialize the SfChart
    
    SfChart chart = new SfChart();
    
    LineSeries series = new LineSeries();
    
    series.ItemsSource = UsersList;
    
    series.XBindingPath = "Date";
    
    series.YBindingPath = "NoOfUsers";
    
    var content = chart.Series.add(series);
    
    //Add content to navigator
    
    rangenavigator.Content = content;

    The following screenshot illustrates the result of the above code sample.

    NOTE

    The SelectedData property of the date-time range navigator control returns the collection that represents the data between the selected ranges.
