Important

Beginning with Windows 8 and Windows Server 2012, RDS server components are no longer included in the Windows operating system (see Windows 8 and Windows Server 2012 Compatibility Cookbook for more detail). RDS client components will be removed in a future version of Windows. Avoid using this feature in new development work, and plan to modify applications that currently use this feature. Applications that use RDS should migrate to WCF Data Service.

The following code shows how to set the RDS.DataControl Server parameter at designtime and bind it to a data-aware HTML table using a data source. Cut and paste the following code to Notepad or another text editor and save it as FilterColumnVBS.asp.
