Binding to Array or IEnumerable
RadTimeline can be bound either to Array or IEnumerable. The following example shows how to bind RadTimeline objects to both Array and IEnumerable, at runtime.
The declaration of RadTimeline objects includes no DataSourceID property or <Items> section:
<telerik:RadTimeline runat="server" ID="RadTimeline1"></telerik:RadTimeline>
<telerik:RadTimeline runat="server" ID="RadTimeline2"></telerik:RadTimeline>
In the Page_Load event handler, create the IEnumerable collections, and bind them to the RadTimeline objects. The DataBind method must be called after setting the DataSource property.
protected void Page_Load(object sender, EventArgs e)
{
var ds = new List<MyTimelineItem>()
{
new MyTimelineItem(){
Title = "My title",
Subtitle= "My subtitle",
Date= DateTime.Now.AddDays(23),
Description="My item description",
Images = new List<MyImage>()
{
new MyImage(){ Src="https://via.placeholder.com/64" },
new MyImage(){ Src="https://via.placeholder.com/32x64" },
},
Actions = new List<MyAction>()
{
new MyAction(){ Text = "Go here", Url="https://www.google.com/search?q=here"},
new MyAction(){ Text = "Go there", Url="https://www.google.com/search?q=there"}
}
}
};
