IActionable是DNN框架提供给模块制作者一个简单的菜单管理接口。这里主要讨论怎么使用它。
使用方法：
在声明类的时候在类名后面声明Implements Entities.Modules.IActionable，然后在下面实现它里面的必须实现的一个属性：Entities.Modules.IActionable.ModuleActions。例如：
Public ReadOnly Property ModuleActions() As Entities.Modules.Actions.ModuleActionCollection Implements Entities.Modules.IActionable.ModuleActions
Get
Dim Actions As New Entities.Modules.Actions.ModuleActionCollection
Actions.Add(GetNextActionID, Localization.GetString(Entities.Modules.Actions.ModuleActionType.AddContent, LocalResourceFile), Entities.Modules.Actions.ModuleActionType.AddContent, "", "", EditUrl(), True, Security.SecurityAccessLevel.Edit, True, False)
Return Actions
End Get
End Property
ModuleActionCollection的add方法有两个重载，这里总结一下其中一个：
|
Property |
Value |
Sample Data |
|
|
ID As Integer [Each module action must have a unique ID. Use the GetNextActionID method to generate a unique id] |
GetNextActionID |
3 |
|
|
Title As String [Sets the text displayed on the menu] |
Localization.GetString(Entities.Modules.Actions .ModuleActionType.AddContent, LocalResourceFile) |
"Add Question" |
|
|
CmdName As String [The command name passed to the client when this action is clicked. Used for JavaScript] |
Entities.Modules.Actions.ModuleActionType.AddContent |
"AddContent.Action" |
|
|
CmdArg As String [The command argument passed to the client when this action is clicked. Used for additional parameters passed to JavaScript] |
"" |
"" |
|
|
Icon As String [The URL of the Icon to place next to this action] |
"" |
"" |
|
|
Url As String [The destination URL to redirect the client browser when this action is clicked.] |
EditUrl() |
"http://localhost/DotNetNuke/Home/tabid/36/ ctl/Edit/mid/423/Default.aspx" |
|
|
UseActionEvent As Boolean [Determines whether client will receive an event notification] |
False |
||
|
Secure As DotNetNuke.Security.SecurityAccessLevel [The security access level required for access to this action] |
SecurityAccessLevel.Edit |
1 |
|
Visible As Boolean [Whether this action will be displayed] |
True |
True |
|
NewWindow As Boolean [Whether this action will be displayed in a new window] |
False |
False |
另一个请参见ModuleActionCollection。
这里说以下URL的参数的值，它用EditUrl（）返回一个链接给它，而我们经常看见的点击设置或者编辑按钮就会跳转到相应的设置页面或者编辑页面，也是用EditUrl（）这个方法的。这个方法怎么跳转至设置控件，请参见DNN自带的文档《DotNetNuke 4.0 Module Development (Part 1)》的NavigateURL: How to make a link部分（p74）。
按照参数和格式写了实现代码後，自己的模块的下拉菜单部分就有了自己增加的菜单项了。
可是有时候我们不需要它跳转至某个设置页而是执行我们想要的动作怎么办？（比如显隐某部分）这时就需要用到它的自定义逻辑功能了。分几步实现这个功能：
首先需要告诉框架我们需要不需要自定义逻辑功能，这里是ModuleActionCollection的add方法的参数UseActionEvent设置为true就可以了。
在当前模块的后台代码中注册页面事件。这里以HTML模块为例子：
在处理load事件的方法的后面写下下面的注册语句，记住ModuleAction_Click。
' menu action handler
Dim ParentSkin As UI.Skins.Skin = UI.Skins.Skin.GetParentSkin(Me)
'We should always have a ParentSkin, but need to make sure
If Not ParentSkin Is Nothing Then
'Register our EventHandler as a listener on the ParentSkin so that it may tell us when a menu has been clicked.
ParentSkin.RegisterModuleActionEvent(Me.ModuleId, AddressOf ModuleAction_Click)
End If
定义处理事件函数ModuleAction_Click。
Public Sub ModuleAction_Click(ByVal sender As Object, ByVal e As Entities.Modules.Actions.ActionEventArgs)注意这里的e是ActionEventArgs类，它有两个属性可以使用: Action和ModuleConfiguration，分别是ModuleAction和ModuleInfo类型。这两个类型包含了很多信息，比如刚才点击的是什么菜单项的信息，那么用select case判断以后就可以分别处理各个菜单项的点击後所要发生的事情了。最后如果是跳转的话仍要给予它跳转：
If e.Action.Url.Length > 0 Then
Response.Redirect(e.Action.Url, True)
End If
这里总结一下ModuleAction和ModuleInfo类型有的属性，具体请分别参见两个类。
ModuleAction：
ID
Title
CmdName
CmdArg
Icon
Url
ClientScript
UseActionEvent
Secure
Visible
NewWindow
ModuleInfo：（写的虽然是私有方法，是为了拷贝方便才考这些，有相应的公共属性的）
