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#region 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 System.Web.UI.Control _innerUserControl;
        #endregion
        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：#region 二.重载WebPart1的父类的CreateChildControls()方法，在其中载入第一步创建的UserControl：
        protected override void CreateChildControls()
        {
            _innerUserControl = this.Page.LoadControl("/bin/WebUserControl1.ascx");
            this.Controls.Add(_innerUserControl);
        }
        #endregion
        三.在RenderWebPart()方法中输出载入的UserControl：#region 三.在RenderWebPart()方法中输出载入的UserControl：
        /**//// <summary>
        /// Render this Web Part to the output parameter specified.
        /// </summary>
        /// <param name="output"> The HTML writer to write out to </param>
        protected override void RenderWebPart(HtmlTextWriter output)
        {
//            output.Write(SPEncode.HtmlEncode(Text));
            this.EnsureChildControls();
            _innerUserControl.RenderControl(output);
        }
        #endregion
    }
}

  配置WebPart,即修改 WebPart1.dwp 代码如下:

<?xml version="1.0" encoding="utf-8"?>
<WebPart xmlns="http://schemas.microsoft.com/WebPart/v2" >
    <Title>李燕平的WebPart1</Title>
    <Description>第一个webpart</Description>
    <Assembly>WebPartLibrary1</Assembly>
    <TypeName>WebPartLibrary1.WebPart1</TypeName>
    <!-- Specify initial values for any additional base class or custom properties here. -->
</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:

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!!
