Declarative DataSource Binding

Timeline can be bound to all ASP.NET Data Source controls:

  • AccessDataSource
  • ObjectDataSource
  • XmlDataSource

  • LinqDataSource

Databinding properties and methods used when binding Timeline to a data source:

  • DataSource property - set to an instance of the data source.
  • DataSourceID property - set to the ID of the data source.
  • DataMember property - if the data source is a DataSet and DataMember is a set, then Timeline is bound to the DataTable with the respective name in the DataSet.
  • DataDateField property - field name from the data source to bind to the Date property of the TimelineItem.
  • DataTitleField property - field name from the data source to bind to the Title property of the TimelineItem.
  • DataSubtitleField property - field name from the data source to bind to the Subtitle property of the TimelineItem.
  • DataDescriptionField property - field name from the data source to bind to the Description property of the TimelineItem.
  • DataImagesField property - field name from the data source to bind to the Images collection.
  • DataActionsField property - field name from the data source to bind to the Actions collection.
