Gets a DataSet that describes the structure of the data requested by the server.
Assembly: Microsoft.Office.Visio.Server (in Microsoft.Office.Visio.Server.dll)
The data extensibility framework sets this property before BeginGetData(HttpContext, AsyncCallback, Object) is invoked based on information from the DataBinding XML Part of the requested document. The DataSet contains one DataTable. Each DataColumn of the DataTable specifies the name of a column and the type of data on that column. The DataTable has no DataRows.
