Binding to ASP DataSource components

RadTimeline supports binding to all ASP.NET 2.0 DataSource components, including:

To bind to a DataSource component, all you need to do is set the DataSourceID property of RadTimeline to the ID of the DataSource component. You should also set the DataTextField and DataValueField properties of RadTimeline to map the Date, Title, Subtitle, Description, Actions and Images values of the items to the respective columns / fields from the data source.

If you need to map additional columns from the data source to properties of RadTimeline items, you can use the ItemDataBound event. The event arguments passed to the event, e.Item and e.Item.DataItem, hold the instance of RadTimeline item being bound and the DataItem to which it is bound. You can map a property from the DataItem to the corresponding property of RadTimeline item. Be sure to cast the DataItem object to the proper data type first.

protected void RadTimeline1_ItemDataBound(object sender, RadTimelineItemEventArgs e)
{
    var dataItem = e.Item.DataItem as DataRowView;
    var orderID = dataItem["OrderID"].ToString();
    e.Item.Actions.Add(new TimelineItemAction()
    {
        Text = "Go to order",
        Url = "https://google.com/search?q=" + orderID
    });

    DataRow[] orderActions = OrderActionsTable().Select("OrderID = " + orderID);
    foreach (DataRow row in orderActions)
    {
        e.Item.Actions.Add(new TimelineItemAction()
        {
            Text = row["Text"].ToString(),
            Url = row["Url"].ToString()
        });
    }
}
Protected Sub RadTimeline1_ItemDataBound(ByVal sender As Object, ByVal e As RadTimelineItemEventArgs)
    Dim dataItem = TryCast(e.Item.DataItem, DataRowView)
    Dim orderID = dataItem("OrderID").ToString()
    e.Item.Actions.Add(New TimelineItemAction() With {
        .Text = "Go to order",
        .Url = "https://google.com/search?q=" & orderID
    })
    Dim orderActions As DataRow() = OrderActionsTable().[Select]("OrderID = " & orderID)

    For Each row As DataRow In orderActions
        e.Item.Actions.Add(New TimelineItemAction() With {
            .Text = row("Text").ToString(),
            .Url = row("Url").ToString()
        })
    Next
End Sub

XmlDataSource

<telerik:RadTimeline runat="server" ID="RadTimeline1" DataSourceID="XmlDataSource1"
    OnItemDataBound="RadTimeline1_ItemDataBound"
    DataMember="Appointment"
    DataDateField="FoundedDate"

</telerik:RadTimeline>

<asp:XmlDataSource runat="server" ID="XmlDataSource1" 
    DataFile="~/App_Data/XmlDataSourceExampleTemp.xml"></asp:XmlDataSource>

The data fields of the used XmlDataSource should be Attributes instead of child node elements. The XML file should have the format shown below:

<Customers>
    <Customer CustomerID="0" FoundedDate="2010-05-01T08:00Z" CompanyName="Alfreds Futterkiste" ContactName="Maria Anders">
        <Actions>

        </Actions>
    </Customer>
    <Customer CustomerID="1" FoundedDate="2010-05-02T08:00Z" CompanyName="Antonio Moreno Taqueria" ContactName="Ana Trujillo"></Customer>
    <!-- Wrong syntax: -->
    <!-- <Customer  FoundedDate="2010-05-02T08:00Z"> -->
