# Data Binding

You can directly bind your preferred series to your data, the currently supported data sources are:

* **IList** interface for one-dimensional arrays.

* **IListSource** interface (like DataTable and DataSet classes).

* **IBindingList** interface. For example the generic BindingList class.

* **IBindingListView** interface. For example BindingSource class.

To bind the series you need to set the **ValueMember** property. The following example demonstrates this.

#### Bind Series to a DataTable

```C#
DataTable table;
public void AddBoundSeries()
{
    table = new DataTable();
    table.Columns.Add("Value", typeof(double));

    table.Rows.Add(1);
    table.Rows.Add(-3);
    table.Rows.Add(5);
    table.Rows.Add(1);
    table.Rows.Add(6);
    table.Rows.Add(-1);
    table.Rows.Add(3);
    table.Rows.Add(-5);
    table.Rows.Add(1);
    table.Rows.Add(6);

    SparkLineSeries lineSeries = new SparkLineSeries();

    lineSeries.ValueMember = "Value";
    lineSeries.DataSource = table;

    lineSeries.ShowMarkers = true;
    lineSeries.ShowHighPointIndicator = true;
    lineSeries.ShowLowPointIndicator = true;

    radSparkline1.Series = lineSeries;
}
```

```VB.NET
Private table As DataTable
Public Sub AddBoundSeries()
    table = New DataTable()
    table.Columns.Add("Value", GetType(Double))

    table.Rows.Add(1)
    table.Rows.Add(-3)
    table.Rows.Add(5)
    table.Rows.Add(1)
    table.Rows.Add(6)
    table.Rows.Add(-1)
    table.Rows.Add(3)
    table.Rows.Add(-5)
    table.Rows.Add(1)
    table.Rows.Add(6)

    Dim lineSeries As New SparkLineSeries()

    lineSeries.ValueMember = "Value"
    lineSeries.DataSource = table

    lineSeries.ShowMarkers = True
    lineSeries.ShowHighPointIndicator = True
    lineSeries.ShowLowPointIndicator = True

    radSparkline1.Series = lineSeries
End Sub
```

The bellow image show the result from the above code.
