IRdsParamsControlInstance.Data

Syntax

Description

The Data property returns data of dictionary attributes, which values are taken as values for parameters of a linked dictionary.

Example

Executing the example requires a form with the btnPData 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 btnPDataOnClick(Sender: Object; Args: IMouseEventArgs);
Var
    Mb: IMetabase;
    Dict: IRdsDictionary;
    DictInst: IRdsDictionaryInstance;
    ElData: IRdsDictionaryElementData;
    iAttrKey: Integer;
Begin
    Mb := MetabaseClass.Active;
    Dict := Mb.ItemByIdNamespace("MAINDICT", Mb.GetObjectKeyById("NSI_1")).Bind As IRdsDictionary;
    iAttrKey := Dict.Attributes.FindById("PARAM_ATTR").Key;
    DictInst := Dict.Open(Null);
    ElData := DictInst.CreateElementData;
    ElData.Attribute(iAttrKey) := 0;
    Text := DictInst.Links.Item(0).ParamsControl(ElData).Data.Attribute(iAttrKey) As String;
End Sub btnPDataOnClick;

After executing the example, the form title displays element value by attribute that controls parameter values of the linked dictionary, which key is passed using the iAttrKey parameter.
