portal學習--模板及模塊的製作
1.所有的模板都繼承自PortalModuleControl(移動設備則繼承自MobileModuleControl),為了網站速度,還定義一個類CachedPortalModuleControl(繼承自Control),它們一並放在Components/DesktopControls.cs文件裡.其中PortalModuleControl的源代碼如下,至於CachedPortalModuleControl的代碼就不列出來了:
/// <summary>
/// 門戶站點用戶控件基類
/// </summary>
public class PortalModuleControl : UserControl
{
// 私有變量
private ModuleSettings _moduleConfiguration; //模塊設置信息
private int _isEditable = 0; //
private int _portalId = 0; //所屬門戶站點Id
private Hashtable _settings; //
#region 公共屬性
// Public property accessors
/// <summary>
/// 模塊Id
/// </summary>
[Browsable(false),DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
public int ModuleId
{
get
{
return (int) _moduleConfiguration.ModuleId;
}
}
/// <summary>
/// 所屬門戶站點Id
/// </summary>
[Browsable(false),DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
public int PortalId
{
get
{
return _portalId;
}
set
{
_portalId = value;
}
}
/// <summary>

[Browsable(false),DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
public bool IsEditable
{
get
{
// Perform tri-state switch check to avoid having to perform a security
// role lookup on every property access (instead caching the result)
if (_isEditable == 0)
{
// Obtain PortalSettings from Current Context
PortalSettings portalSettings = (PortalSettings)
HttpContext.Current.Items["PortalSettings"];
if (portalSettings.AlwaysShowEditButton == true ||
PortalSecurity.IsInRoles(_moduleConfiguration.AuthorizedEditRoles))
{
_isEditable = 1;
}
else
{
_isEditable = 2;
}
}
return (_isEditable == 1);
}
}
/// <summary>

[Browsable(false),DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
public ModuleSettings ModuleConfiguration
{
get
{
return _moduleConfiguration;
}

}
}
/// <summary>

public Hashtable Settings
{
get
{
if (_settings == null)
{
_settings = Configuration.GetModuleSettings(ModuleId);
}
return _settings;
}
}
#endregion
}

public class PortalModuleControl : UserControl
{
// 私有變量

}
}
/// <summary>

2.下面以Announcements.ascx為例,講一下模板的實現.
通告模板使用了一個表,用來存儲通告的內容,該表的結構如下:
名稱 型別 長度 空 ItemID int 4 ModuleID int 4 CreatedByUser nvarchar 100 null CreatedDate datetime 8 null Title nvarchar 150 null MoreLink nvarchar 150 null MobileMoreLink nvarchar 150 null ExpireDate datetime 8 null Description nvarchar 2000 null
3.為了操作這個表,我們定義了一類,它用於查找全部的通告,查找單個通告,以及添加,刪除,更新通告,它們分別調用了相應的存儲過程.
public class AnnouncementsDB
{
public DataSet GetAnnouncements(int moduleId)
{
// Create Instance of Connection and Command Object
SqlConnection myConnection = new
SqlConnection(ConfigurationSettings.AppSettings["connectionString"]);
SqlDataAdapter myCommand = new SqlDataAdapter("Portal_GetAnnouncements", myConnection);
// Mark the Command as a SPROC
myCommand.SelectCommand.CommandType = CommandType.StoredProcedure;
// Add Parameters to SPROC
SqlParameter parameterModuleId = new SqlParameter("@ModuleID", SqlDbType.Int, 4);
parameterModuleId.Value = moduleId;
myCommand.SelectCommand.Parameters.Add(parameterModuleId);
// Create and Fill the DataSet
DataSet myDataSet = new DataSet();
myCommand.Fill(myDataSet);
// Return the DataSet
return myDataSet;
}
public SqlDataReader GetSingleAnnouncement(int itemId)
{
// Create Instance of Connection and Command Object
SqlConnection myConnection = new
SqlConnection(ConfigurationSettings.AppSettings["connectionString"]);
SqlCommand myCommand = new SqlCommand("Portal_GetSingleAnnouncement", myConnection);
// Mark the Command as a SPROC
myCommand.CommandType = CommandType.StoredProcedure;
// Add Parameters to SPROC
SqlParameter parameterItemId = new SqlParameter("@ItemID", SqlDbType.Int, 4);
parameterItemId.Value = itemId;
myCommand.Parameters.Add(parameterItemId);
// Execute the command
myConnection.Open();
SqlDataReader result = myCommand.ExecuteReader(CommandBehavior.CloseConnection);
// Return the datareader
return result;

4.開始編輯這個模板的頁面了,通告模板使用一個DataList來顯示數據,新增和修改都是通過其它頁面,這裡只給了每個功能一個鏈接.別急,每個模塊都得有個標題,為了通用,所以也做成了一個用戶控件DesktopModuleTitle.ascx.標題還有模塊的其它一些屬性(如可編輯角色等)也可能要修改,所以在控件裡還放了個LinkButton用來鏈接到修改頁面Admin/ModuleSettings.aspx.
其網頁的全部代碼如下,是全部代碼嗎?對,沒錯:
<%@ Register TagPrefix="ASPNETPortal" TagName="Title" Src="~/DesktopModuleTitle.ascx"%>
<%@ Control Language="c#" AutoEventWireup="false" Codebehind="Announcements.ascx.cs" Inherits="Portal.Web.Announcements" TargetSchema="http://schemas.microsoft.com/intellisense/ie5"%>
<!--新增公告鏈接,在這裡改鏈接的名稱和地址,還有是否開新窗口-->
<ASPNETPortal:title EditText="添加新公告" EditUrl="~/DesktopModules/EditAnnouncements.aspx" runat="server"
id="Title1" />
<asp:DataList id="myDataList" CellPadding="4" Width="98%" EnableViewState="false" runat="server">
<ItemTemplate>
<!--修改公告鏈接-->
<asp:HyperLink id="editLink" runat="server" Visible="<%# IsEditable %>" NavigateUrl='<%# "~/DesktopModules/EditAnnouncements.aspx?ItemID=" + DataBinder.Eval(Container.DataItem,"ItemID") + "&mid=" + ModuleId %>' ImageUrl="~/images/edit.gif">
</asp:HyperLink>
<!--公告標題-->
<SPAN class="ItemTitle"><%# DataBinder.Eval(Container.DataItem,"Title") %></SPAN><BR>
<!--公告內容,這裡給了一個"更多"鏈接,用於查看詳細內容-->
<SPAN class="Normal">
<%# DataBinder.Eval(Container.DataItem,"Description") %>
<asp:HyperLink id="moreLink" runat="server" Visible='<%# DataBinder.Eval(Container.DataItem,"MoreLink") != String.Empty %>' NavigateUrl='<%# DataBinder.Eval(Container.DataItem,"MoreLink") %>'>更多...</asp:HyperLink></SPAN><BR>
</ItemTemplate>
</asp:DataList>
<%@ Control Language="c#" AutoEventWireup="false" Codebehind="Announcements.ascx.cs" Inherits="Portal.Web.Announcements" TargetSchema="http://schemas.microsoft.com/intellisense/ie5"%>
<!--新增公告鏈接,在這裡改鏈接的名稱和地址,還有是否開新窗口-->
<ASPNETPortal:title EditText="添加新公告" EditUrl="~/DesktopModules/EditAnnouncements.aspx" runat="server"
id="Title1" />
<asp:DataList id="myDataList" CellPadding="4" Width="98%" EnableViewState="false" runat="server">
<ItemTemplate>
<!--修改公告鏈接-->
<asp:HyperLink id="editLink" runat="server" Visible="<%# IsEditable %>" NavigateUrl='<%# "~/DesktopModules/EditAnnouncements.aspx?ItemID=" + DataBinder.Eval(Container.DataItem,"ItemID") + "&mid=" + ModuleId %>' ImageUrl="~/images/edit.gif">
</asp:HyperLink>
<!--公告標題-->
<SPAN class="ItemTitle"><%# DataBinder.Eval(Container.DataItem,"Title") %></SPAN><BR>
<!--公告內容,這裡給了一個"更多"鏈接,用於查看詳細內容-->
<SPAN class="Normal">
<%# DataBinder.Eval(Container.DataItem,"Description") %>
<asp:HyperLink id="moreLink" runat="server" Visible='<%# DataBinder.Eval(Container.DataItem,"MoreLink") != String.Empty %>' NavigateUrl='<%# DataBinder.Eval(Container.DataItem,"MoreLink") %>'>更多...</asp:HyperLink></SPAN><BR>
</ItemTemplate>
</asp:DataList>
後台代碼其實沒什麼說的,太簡單了:
protected System.Web.UI.WebControls.DataList myDataList;
private void Page_Load(object sender, System.EventArgs e)
{
// Obtain announcement information from Announcements table
// and bind to the datalist control
AnnouncementsDB announcements = new AnnouncementsDB();
// DataBind Announcements to DataList Control
//通過ModuleId獲取數據,所以相同模板的模塊,它們的數據會不同.
myDataList.DataSource = announcements.GetAnnouncements(ModuleId);
myDataList.DataBind();
}
private void Page_Load(object sender, System.EventArgs e)
{
// Obtain announcement information from Announcements table
// and bind to the datalist control
AnnouncementsDB announcements = new AnnouncementsDB();
// DataBind Announcements to DataList Control
//通過ModuleId獲取數據,所以相同模板的模塊,它們的數據會不同.
myDataList.DataSource = announcements.GetAnnouncements(ModuleId);
myDataList.DataBind();
}
好了,接下來再看看編輯單條通告的頁面是什麼樣的吧,煩,不說了.
5.前期工作終於做完了,開始調用這個模板啦,首先總要告訴系統這個模板的文件位置吧,在系統中用了一個頁面ModuleDefinitions.aspx來做維護,但其實原理還是在PortalCfg.xml中加上一條記錄,ModuleDefId是自動產生的(這裡ModuleDefId="1"),其它幾個都要自已定義.
<ModuleDefinition FriendlyName="公告" MobileSourceFile="MobileModules/Announcements.ascx" DesktopSourceFile="DesktopModules/Announcements.ascx" ModuleDefId="1" />
接下來就要根據這個模板新增模塊了,也做了一個維護頁面TabLayout.aspx,其實也還是在操作這個PortalCfg.xml文件,看到ModuleDefId的定義了嗎?如果ModuleDefId="1",那麼它就是用我們剛才建立的那個通告模板生成的,"新闻和特点" 就是了.想刪除嗎?也在這個頁面了.什麼,還想修改?前面說了,在Admin/ModuleSettings.aspx頁面修改吧.
<Tab TabId="1" TabName="主页" AccessRoles="All Users;" TabOrder="1" ShowMobile="true" MobileTabName="Home">
<Module ModuleId="1" ModuleTitle="快速链接" EditRoles="Admins;" ModuleDefId="8" PaneName="LeftPane" CacheTimeout="0" ModuleOrder="1" ShowMobile="false" />
<Module ModuleId="2" ModuleTitle="欢迎来到 Portal Starter Kit" EditRoles="Admins;" ModuleDefId="5" PaneName="ContentPane" CacheTimeout="0" ModuleOrder="1" ShowMobile="true" />
<Module ModuleId="3" ModuleTitle="新闻和特点" EditRoles="Admins;" ModuleDefId="1" PaneName="ContentPane" CacheTimeout="0" ModuleOrder="2" ShowMobile="true" />
<Module ModuleId="4" ModuleTitle="近期事件" EditRoles="Admins;" ModuleDefId="4" PaneName="ContentPane" CacheTimeout="0" ModuleOrder="3" ShowMobile="true" />
