Filtering configuration options

Compatibility

The content of this page can only be used if the following condition(s) are all met:

  • You must target the Vault Application Framework 2.0 or higher.

There are situations where configuration options should be filtered according to the values of other options.

Filtering workflow state by workflow

For the filtering to work, you must:

  1. Ensure that the configuration elements are in their own class (e.g. WorkflowTrigger, in the sample below).
  2. Add the MFWorkflow attribute to the new class. This is the type of the parent that will drive the filtering.
  3. Add the RefMember property to the MFWorkflow attribute, providing it with the name of the MFIdentifier member that identifies the parent (e.g. WorkflowTrigger.Workflow, in the sample below).
  4. Other configuration values within the class which support filtering will now be filtered by the value of the parent (e.g. State will be filtered by Workflow, in the sample below).

}

Filtering workflow states by workflow

In the MFWorkflow attribute above, the C# nameof operator is used to avoid hard-coding a string value which may change. This could be altered, instead, to: [MFWorkflow(RefMember = "Workflow")].

Filtering workflow state transitions by workflow

For the filtering to work, you must:

  1. Ensure that the configuration elements are in their own class (e.g. WorkflowTrigger, in the sample below).
  2. Add the MFWorkflow attribute to the new class. This is the type of the parent that will drive the filtering.
  3. Add the RefMember property to the MFWorkflow attribute, providing it with the name of the MFIdentifier member that identifies the parent (e.g. WorkflowTrigger.Workflow, in the sample below).
  4. Other configuration values within the class which support filtering will now be filtered by the value of the parent (e.g. Transitions will be filtered by Workflow, in the sample below).
