一步一步webpart-如何利用.net制作第一个webpart?(3)

首先,你已经装好了sharepoint 2003 ,有关sharepoint 2003 安装问题请见我博客的另一篇文章:sharepoint 安装宝典
         另,有很多网友想下载 sharepoint 2003,我用的是公司的.若有知道下载地址的朋友,不妨提供给广大需要者.
开始制作第一个webpart!
用VS.net创建两个项目:
一. 创建"  空Web项目":WebProject1
      添加一个“Web用户控件":WebUserControl1.ascx,去掉 WebUserControl1.ascx的"CodeBehind”和“Inherited”等属性代码如下:

<%@ Control Language="c#" AutoEventWireup="false" TargetSchema="http://schemas.microsoft.com/intellisense/ie5"%>

<asp:Calendar id="Calendar1" runat="server">

</asp:Calendar>

二. 创建 "Web Part Library”项目:WebPartLibrary1
在装好webpart后,打开.net即可看到web part Library如图所示:

WebPart1.cs的代码如下:

using System;

using System.ComponentModel;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Xml.Serialization;

using Microsoft.SharePoint;

using Microsoft.SharePoint.Utilities;

using Microsoft.SharePoint.WebPartPages;

namespace WebPartLibrary1

{

/// <summary>

/// Description for WebPart1.

/// </summary>

[DefaultProperty("Text"),

ToolboxData("<{0}:WebPart1 runat=server></{0}:WebPart1>"),

XmlRoot(Namespace="WebPartLibrary1")]

public class WebPart1 : Microsoft.SharePoint.WebPartPages.WebPart

{

一.在WebPart1类中定义一个用来保存第一步中创建的UserControl的对象

private const string defaultText = "";

private string text = defaultText;

[Browsable(true),

Category("Miscellaneous"),

DefaultValue(defaultText),

WebPartStorage(Storage.Personal),

FriendlyName("Text"),

Description("Text Property")]

public string Text

{

get

{

return text;

}

set

{

text = value;

}

/// <summary>

/// This method gets the custom tool parts for this Web Part by overriding the

/// GetToolParts method of the WebPart base class. You must implement

/// custom tool parts in a separate class that derives from

/// Microsoft.SharePoint.WebPartPages.ToolPart.

/// </summary>

///<returns>An array of references to ToolPart objects.</returns>

// public override ToolPart[] GetToolParts()

// {

// ToolPart[] toolparts = new ToolPart[2];

// WebPartToolPart wptp = new WebPartToolPart();

// CustomPropertyToolPart custom = new CustomPropertyToolPart();

// toolparts[0] = wptp;

// toolparts[1] = custom;

// return toolparts;

// }

二.重载WebPart1的父类的CreateChildControls()方法，在其中载入第一步创建的UserControl：

三.在RenderWebPart()方法中输出载入的UserControl：

}

配置WebPart,即修改 WebPart1.dwp 代码如下:

<?xml version="1.0" encoding="utf-8"?>

<Title>李燕平的WebPart1</Title>

<Description>第一个webpart</Description>

<Assembly>WebPartLibrary1</Assembly>

<TypeName>WebPartLibrary1.WebPart1</TypeName>

</WebPart>

说明:

Title : 显示在SPS页面上的标题

Description : 显示在SPS页面上的提示文字

Assembly : 编译出来的dll文件的文件名（勿加“.dll”）

TypeName : 完整的WebPart的类名称（包含Namespace）

三.打开承载SPS站点的虚拟主机的根目录，编辑web.config文件
可能有的朋友不知道这个目录在那,请见图示:

web.config文件原码:

</sectionGroup>

</configSections>

<!--

SafeControl Attributes:

Assembly="[Assembly]" - The .NET assembly in which the control is contained. This attribute can also contain version, culture, and public key token information.

Namespace="[Namespace]" - The .NET namespace in which the control is defined.

TypeName="[Typename]" - The .NET class name of the control. You can type an asterisk (*) wildcard character to indicate all TypeNames in a Namespace.

Safe="[True|False]" - Specifies whether a Web Part or Web Form Control is safe and can be displayed on a Web Parts Page. This attribute is True by default.

-->

</SafeControls>

</SharePoint>

<system.web>

</securityPolicy>

</httpHandlers>

</authorization>

</httpModules>

</system.web>

</configuration>

说明:
      1.<safecontrol...>中的信息要和WebPart1.dwp 一致
       2.<SafeControl Assembly="WebPartLibrary1" Namespace="WebPartLibrary1" TypeName="*" Safe="True" />不要写成
         <SafeControl Assembly="WebPartLibrary1" Namespace="WebPartLibrary1.WebPart1" TypeName="*" Safe="True" />
四.导入创建的webPart到SPS中
导入之前需要将刚才创建的“WebUserControl1.ascx”和“WebPartLibrary1.dll”拷贝到承载SPS站点的虚拟主机的根目录下的“bin”目录下;
导入过程:
1.点击门户网站上的"网站设置";
2.点击"常规设置"下的"管理安全性和附加设置";
3.点击"模板和 Web 部件"下的"管理 Web 部件库";
4.点击"上载 Web 部件";
5.浏览到"WebPart1.dwp",选择"默认web部件"组,保存!OK了,本节结束!!
