Link Properties

To set up link parameters between attributes, use the Links Properties dialog box.

Select the add a new or edit an old link operations on the Link tab.

Enter name and unique identifier of the link. Only English letters, numbers and underscores are allowed; spaces are not allowed.

Determine parameters in the Link Parameters group:

Linking Attribute. From drop-down list select the attribute which is the base to create a link with another dictionary.
This list contains only the attributes that have not yet been used to form links.
Linked attribute must be an integer. If linked attribute is not an integer, you will be asked to change attribute data type.
Dictionary. From the drop-down menu select the dictionary to establish a connection with this dictionary by the attribute having the KEY identifier. The following groups become available after dictionary selection: Group of Elements, Show Field as Value and View Format.
Group of Elements. This drop-down menu includes all element groups of the dictionary selected under the Dictionary field and the [All elements] option (selected by default). If the dictionary has no element groups, the list includes only the [All elements] option.
If the [All Elements] option is selected, on creating or editing an MDM dictionary element for which you create the link the value of linked attribute shows all elements of the dictionary with which the link is established.
If a group is selected, on dictionary element creation or editing the value of linked attribute shows only elements included into this group.
Show Field as Value. Select attribute of the linked dictionary, values of which are to be displayed as values for the linked attribute of the current dictionary. Values of the Name attribute are used by default.
View Format. Select view format of linking attribute value from drop-down list. The following display formats are available: Key, Value, Key(Value). The Key(Value) format is displayed by default.
Cascade Deletion of Linked Items. When this checkbox is selected, the linked items in the current dictionary are deleted if they have been deleted in the linked dictionary.

If the selected dictionary is a parameterized one, the dialog box displays the parameter tree of the linked dictionary:

This tree is used to map attributes of the current dictionary to parameters of the linked dictionary or to specify a static value.

NOTE. If a parameter identifier and its type coincide with the data of a parameter of an edited dictionary attribute, mapping will be done automatically.

Work with Binding

To create a binding:

Double-click the selected parameter with the main mouse button.
Select the Link item in the context menu of the selected parameter.

The Binding Parameters dialog box opens after executing one of the actions:

Determine binding type, by selecting corresponding radio button:

Dynamic Value. This type binds a parameter to an attribute of an edited dictionary. This type enables to change the value of the linked dictionary parameter, when the attribute value is changed. The drop-down menu includes all linkable attributes of the current dictionary.
Static Value. This type enables to set a static value. The following situations are possible:

If in the linked dictionary the parameter is linked to another dictionary, the field displays the list of elements of this dictionary.
If the parameter is not linked to another dictionary, a value corresponding to the parameter type can be set. To set a value, the expression editor can be used that opens on clicking the button.
