The init method can be overridden on a form data source. Right-click the Methods node under the data source, point to Override Method, and then click init.

Examples

The following example overrides the init method on a data source to specify the sorting order for the data source.

public void init() 
{ 
    super(); 
    this.query().dataSourceTable( 
        tablenum(SysVersionControlTmpItem)).addSortField( 
            fieldnum(SysVersionControlTmpItem, VCSDate), 
        SortOrder::Descending); 
    this.query().dataSourceTable( 
        tablenum(SysVersionControlTmpItem)).addSortField( 
            fieldnum(SysVersionControlTmpItem, VCSTime), 
        SortOrder::Descending); 
    this.query().dataSourceTable( 
        tablenum(SysVersionControlTmpItem)).addSortField( 
            fieldnum(SysVersionControlTmpItem, ChangeNumber), 
        SortOrder::Ascending); 
}
