ReadFromXMLStream


Unit:SDL_replist
Class:TReportListView
Declaration:function ReadFromXMLStream (InStream: TStream; DataID: string): boolean;

The function ReadFromXMLStream reads the data from the current position of the stream InStream. If the parameter DataID is empty, the first <replist> tag is evaluated and read into the report listview. If DataID is not empty, the entire rest of the stream is read until a <replist> tag is found whose attribute "id " matches DataID (the recognition of the "id " attribute is not case-sensitive). The property DataID is set to the identification string of the XML data source. The function ReadFromXMLStream returns TRUE if both a valid starting tag <replist> and a valid end tag </replist> has been found and the report listview has been updated. In this case the OnChange event is triggered.

Hint 1: The XML description of the listview data has to follow a certain order: number of columns and rows have to precede all other data of the control.

Hint 2: ReadFromXMLStream is by a factor of 5 slower than ReadFromOpenXMLFile. Thus you should avoid to use ReadFromXMLStream when reading large listviews with more than approx. 10000 cells.
