LoadFromXMLFile


Unit:SDL_replist
Class:TReportListView
Declaration:function LoadFromXMLFile (FName: string; DataID: string): boolean;

The function LoadFromXMLFile reads a report listview from the file FName. 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 file 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 LoadFromXMLFile 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 1: For a description of the valid tags, please see WriteToOpenXMLFile.

Hint 2: The XML description of the report listview data has to obey a certain order: number of columns and rows have to precede all other data of the control.

Example: This method is used in the following example program (see http://www.lohninger.com/examples.html for downloading the code): replistv
