IRdsElementsSorter.Save

Syntax

Save;

Description

The Save method saves results of dictionary elements sorting in the database.

Example

Create a form, place the following components on it: a button named Button1, the RdsDictionaryBox component named RdsDictionaryBox1 and the UiRdsDictionary component that is a data source for RdsDictionaryBox1.

Class OBJ26217Form: Form
    RdsDictionaryBox1: RdsDictionaryBox;
    UiRdsDictionary1: UiRdsDictionary;
    Button1: Button;
    dictionary: IRdsDictionaryInstance;
    sorter: IRdsElementsSorter;

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
    com: CustomComparer;
Begin
    com := New CustomComparer.Create;
    sorter := dictionary.Elements.CreateSorter(dictionary.Elements.Root);
    sorter.Comparer := com As IRdsElementComparer;
    sorter.Sort(True);
    sorter.Save;
    RdsDictionaryBox1.RefreshElements;
End Sub Button1OnClick;

Sub OBJ26217FormOnShow(Sender: Object; Args: IEventArgs);
Begin
    dictionary := RdsDictionaryBox1.Source.Instance;
End Sub OBJ26217FormOnShow;
End Class OBJ26217Form;

Class CustomComparer: Object, IRdsElementComparer
Function Less(LValue: IRdsDictionaryElement; RValue: IRdsDictionaryElement): Boolean;
Var
    comp: IComparer;
Begin
    comp := comparer.StringCaseInsensitiveComparer;
    If (Comp.Compare(LValue.Name, RValue.Name) > 0) Then Return True
        Else Return False;
    End If;
End Function Less;
End Class CustomComparer;

After executing the example, pressing the button creates a custom sorter of the MDM dictionary elements and saves the result of dictionary element sorting in the database.
