ReadFromOpenXMLFile |
|
Unit: | SDL_replist | Class: | TReportListView | Declaration: | function ReadFromOpenXMLFile (var InFile : TextFile; DataID: string): boolean; |
The function ReadFromOpenXMLFile reads a report listview from the current position of the file InFile. If the parameter DataID is empty, the first <replist> tag is evaluated and read into the listview control. If DataID is not empty, the entire rest of the open file InFile 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 ReadFromOpenXMLFile returns TRUE if both a valid starting tag <replist> and a valid end tag </replist> has been found and the report list view has been updated. In this case the OnChange event is triggered.
Hint 2: |
The XML description of the report listview data has to follow a certain order: number of columns and rows have to precede all other data of the control. |
Hint 3: |
ReadFromOpenXMLFile is by a factor of 5 faster than ReadFromXMLStream. Thus you should use ReadFromOpenXMLFile when reading large listviews with more than approx. 10000 cells. |
