用vs2005为sharepoint开发webpart步骤(最简单、自定义、通讯)

最简单的webpart

1，在vs2005中新建类库 class library

2，添加引用 .net 的System.Web

3,在cs文件中添加using

using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;

4,让类继承 System.Web.UI.WebControls.WebParts.WebPart

5,重写方法

        protected override void RenderContents(HtmlTextWriter writer)
        {
            //base.RenderContents(writer);
            writer.Write("<font color=\"red\" >hello</font>");
        }

6，生成项目

7，把DLL文件复制到 sharepoint 网站的bin目录下

8，修改sharepoint 网站的web.config文件，针对DLL文件增加safecontrol节点，保存web.config文件

9，SharePoint网站设置－库－Ｗeb 部件－新建－选择我们的webpart－导入库

10，在web页面上添加该webpart控件

具有自定义属性的webpart

要使普通属性成为自定义属性，需要给每个属性添加上相应的Attribute修饰

[Personalizable]
        [WebBrowsable]
        [WebDisplayName("输出文本")]
        [WebDescription("要输出的文本")]

sharepoint会自动检测自定义属性的数据类型，来自动显示出不同的web控件。，例如：字符串、整数、浮点数－文本框；枚举－列表框；bool-复选框

webpart之间传递数据

根据要传递的数据类型，定义一个数据接口，并在一个类中实现这个接口

创建provider web part ，在其中创建一个方法来返回要提供的数据，该方法用[ConnectionProvider("")]标记

创建consumer web part ，在其中创建一个方法来接收数据，该方法用[ConnectionConsumer("")]标记

在放置webpart的页面上设置连接

TextMessage.cs

using System;
using System.Collections.Generic;
using System.Text;

namespace beta2webparts
{
    public interface ITextMessage
    {
        string MessageContent { get;set;}
    }
    class TextMessage:ITextMessage
    {
        private string _sMessageContent = default(string);

        public string MessageContent
        {
            get
            {
                return _sMessageContent;
            }
            set
            {
                _sMessageContent = value;
            }
        }
    }
}

TextInputWP.cs

using System;
using System.Collections.Generic;
using System.Text;
using System.Web;

using System.Web.UI.WebControls.WebParts;

{
    public class TextInputWP:System.Web.UI.WebControls.WebParts.WebPart
    {
        private TextBox _txtMessage = null;

        protected override void CreateChildControls()
        {

            _txtMessage = new TextBox();
            Button btn = new Button();
            btn.Text = "submit";

            this.Controls.Add(_txtMessage);
            this.Controls.Add(btn);
            base.CreateChildControls();
        }

        [ConnectionProvider("return the text message")]
        public ITextMessage ReturnTextMessage()
        {
            this.EnsureChildControls();
            ITextMessage result = new TextMessage();
            result.MessageContent = _txtMessage.Text;
            return result;
        }
    }
}
