IRdsLink.ParamsControl

Syntax

Description

The ParamsControl property returns settings of parameter binding. This property is relevant if connection with the parametric dictionary is executed.

Example

Executing the example requires the MDM repository NSI_1 that contains MDM dictionaries with the Dict_1 and Dict_2 identifiers. The second dictionary has one parameter.

Sub Main;

Var

MB: IMetabase;

MObj: IMetabaseObject;

Dict, Dict2: IRdsDictionary;

Attrs: IRdsAttributes;

LinkAttr, ParamAttr: IRdsAttribute;

Link: IRdsLink;

Param: IRdsParam;

ParamsControl: IRdsParamsControl;

Begin

MB := MetabaseClass.Active;

MObj := MB.ItemByIdNamespace("Dict_1", MB.ItemById("NSI_1").Key).Edit;

Dict := MObj As IRdsDictionary;

Dict2 := MB.ItemByIdNamespace("Dict_1", MB.ItemById("NSI_1").Key).Bind As IRdsDictionary;

//Attributes of the first dictionary

Attrs := Dict.Attributes;

//Attribute to link with the dictionary

LinkAttr := Attrs.Add;

LinkAttr.DataType := DbDataType.Integer;

LinkAttr.Id := "LinkAttr";

LinkAttr.Name := Attribute to link;

//Connection with the parameterized dictionary

Link := Dict.Links.Add;

Link.Attribute := LinkAttr;

Link.Reference := Dict2.Attributes.Key;

Link.Id := "Link";

Link.Name := Link with the dictionary Dict_2;

//Parameter necessary to control

ParamsControl := Link.ParamsControl;

Param := ParamsControl.ReferenceDictionary.Params.Item(0);

//Attribute to link with the dictionary

ParamAttr := Attrs.Add;

ParamAttr.DataType := Param.Attribute.DataType;

ParamAttr.Id := "ParamAttr";

ParamAttr.Name := Parameter control;

//Attribute binding with the parameter of the second dictionary

ParamsControl.ParamAttribute(Param) := ParamAttr;

MObj.Save;

End Sub Main;

After executing the example two attributes are created in the first dictionary: the first one is used to connect with the Dict_2 dictionary; the second one is used to control parameter values of the Dict_2 dictionary. Connection is set up between the Dict_1 and Dict_2 dictionaries by the Key attribute, the ParamAttr attribute is used to control parameter values of the linked Dict_2 dictionary.
