IRdsParamsControlInstance.Link

Syntax

Description

The Link property returns a link with a dictionary, which parameters are necessary to control.

Example

Executing the example requires a form with the btnPLink button, and an MDM repository with the NSI_1 identifier that contains an MDM dictionary with the MAINDICT identifier. The dictionary has an attribute with the PARAM_ATTR identifier that is used to control parameters of the linked dictionary. Add links to the Metabase, Rds and Forms system assemblies.

The example is a handler of the OnClick event for the button.

Sub btnPLinkOnClick(Sender: Object; Args: IMouseEventArgs);
Var
    Mb: IMetabase;
    Dict: IRdsDictionary;
    DictInst: IRdsDictionaryInstance;
    ElData: IRdsDictionaryElementData;
Begin
    Mb := MetabaseClass.Active;
    Dict := Mb.ItemByIdNamespace("MAINDICT", Mb.GetObjectKeyById("NSI_1")).Bind As IRdsDictionary;
    DictInst := Dict.Open(Null);
    ElData := DictInst.CreateElementData;
    ElData.Attribute(Dict.Attributes.FindById("PARAM_ATTR").Key) := 0;
    Text := DictInst.Links.Item(0).ParamsControl(ElData).Link.Id;
End Sub btnPLinkOnClick;

After executing the example, the form title displays identifier for the link to the dictionary, which parameters are controlled.
