Link Properties

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. In the 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.
  A linked attribute must be an integer. If a linked attribute is not an integer, it will be asked to change attribute data type.

• Dictionary. In the drop-down list 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. The drop-down list includes all groups of elements of the dictionary selected in the Dictionary box and the [All elements] option (selected by default). If the dictionary has no groups of elements, 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, which values are 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 in the 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 Elements. When this checkbox is selected, the linked elements in the current dictionary are deleted if they have been deleted in the linked dictionary.

Determine a binding type by selecting the corresponding radio button:

• Dynamic Value. This type binds a parameter to an attribute of an edited dictionary. This type enables the user to change the value of the linked dictionary parameter when the attribute value is changed. The drop-down list includes all linkable attributes of the current dictionary.

• Static Value. This type enables the user 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.

To edit the selected binding:

• Double-click the binding with the main mouse button.

• Select the Edit item in the binding's context menu.

The Binding Parameters dialog box opens, the same as on creating a binding.

To delete the selected binding:
