Whenever your .NET plugin exposes functionality to the iCDR service instance, and requires custom configuration sections, it is best practice to expose functions to allow administrators to configure your plugin on the iCDR server.
Features are located on the left hand side of the configuration tool, as shown below:
Each of these features is discovered by scanning your .NET assembly for implementations of IFeature
, an IFeature
defines the following properties:
Group -> The logical grouping where the feature should reside
Description -> A textual description of the feature which is to appear on the detailed configuration
ConfigurationType -> The type of object that the feature is expecting to appear in the configuration file
Name -> The name of the feature to appear in the feature list
The IFeature
expects implementers to provide a function called QueryState
, this method should scan the provided configuration instance and return on of the following values based on the status of the feature in the provided configuration:
NotInstalled
The feature could not be detected in the provided configuration instance
PartiallyInstalled
The feature has some attributes on the configuration file, but is incomplete for full feature startup
Installed
The feature is enabled
When a feature is enabled the CreateInstallTasks
method is called, and should return one or more IConfigurationTask
instances which perform the setup/enable function. Conversely, when the feature is disabled, the CreateUninstallTasks
method is called.
The IConfigurationTask
interface is used to control individual configuration steps to modify the provided file to perform a configuration or removal of a feature. You can see these in the confirm tasks dialog.
Each task can be enabled/disabled by an administrator to skip the specified task in their environment.
When the administrator clicks Ok
on the Confirm Tasks
dialog box, the IConfigurationTask
method VerfiyState
is called. Your task should verify that the task is required, or should run, if so the VerifyState
method should return true.
The Execute
method of the task should perform the necessary configuration tasks to alter the configuration for the administrator. The Rollback
method is called in the case of an error in applying the configuration changes.
Do not save the configuration passed to the Execute or Rollback methods. The saving of the configuration is handled by the configuration tooling. Your methods should only update the configuration variable passed to the method call.
The configuration tooling in SanteDB uses the .NET PropertyGrid
control to expose configuration options. It is recommended that you use the attributes listed below on your properties to allow for proper user experience for configuration of your plugin.
Attribute | Use | Example |
| Controls the display name of the configuration property |
|
| Provides contextual help on the property grid which describes how the setting should be used. |
|
| Use this attribute to control whether your setting should appear in the configuration tool. |
|
| When your configuration setting needs to be shown, but not edited. |
|
| When you would like to allow a user to edit the value using a complex editor (see below) | |
| The type converter used to convert input from the property grid to/from the class. |
For more information on how to use the PropertyGrid settings see https://www.codeproject.com/articles/22717/using-propertygrid
You can instruct the property grid to use a custom editor for your values. In addition to the standard .NET editors, SanteDB provides additional editors.
When you wish to expose restrictions on resource types for your plugin, you would normally use a collection of ResourceTypeReferenceConfiguration
.
You can allow users to select defined resources in this property value by using referencing the resource selector editor with:
You can allow users to select from any system type which you'd like referenced on your solution whenever a TypeReferenceConfiguation
property is needed. For example, if your plugin has configuration for more functions as:
You can annotate the class with the type editor:
Additionally, using the Binding
attribute will allow you to filter from any type to a specific type. For example, to only allow selection of a type which implements IMyPluginExtension
