As part of Dynamic HTML, Data Awareness is a new feature of Internet Explorer 4.0 that allows data display and manipulation on the client. The Data Awareness features are enabled by the introduction of W3C-proposed HTML extensions and including a Data Source Component on the HTML page. The HTML extensions allow the author to bind elements of a page to columns of a data set (details on these HTML extensions can be found in the HTML reference included with the Internet Explorer 4.0 SDK). One or more Data Source Components supply data to the elements on the page with the HTML extensions. Data Source Components can be ActiveX controls (written in VC or VB) or Java applets.
Two data source components ship as an integral part of Internet Explorer 4.0: the Advanced Data Connector and the Tabular Data Control. Issues with these components are explained in the following sections.

Current known issues with Data Awareness support in IE4 are:
(a) When a row is added/deleted to a data set, a bound, repeated table will not display the inserted/deleted row even though it is present/removed in/from the data set. A Refresh() method has been temporarily added to the table to refresh the data set - it will be removed for ship. You can use this to display inserted/deleted rows.
(b) Although the HTML attributes for data binding are accessible from the Dynamic-HTML object model, changes to these attributes will not cause changes to the bindings. This is a feature that will be added for ship.
Internet Explorer 4.0 exposes the ADO object model on all data providers. Script authors can obtain the ADO recordset by getting the RecordSet property from a Data Source Component.
