步步为营 SharePoint 开发学习笔记系列 四、Web Part开发

 

概要

 

    现在有两种不同的Web部件。老的WSS风格的WebPart依赖于Microsoft.SharePoint.dll,必须继承自WSS 2.0所定义的WebPart基类,其命名空间为Microsoft.SharePoint.WebPartPages。新的ASP风格WebPart依赖于System.Web.dll,必须继承自不同的一个由ASP.NET 2.0定义的WebPart基类,其命名空间为System.Web.UI.WebControls.WebParts。

 

 

 

我们将从简单的hello Word web part 开始:

 

代码设计:

 

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

 

using System.Web.UI.WebControls.WebParts;

using System.Xml.Serialization;

using System.Web.UI;

 

namespace LearnWriteWebPart.Webpart

{

    [ToolboxData("<{0}:SampleWebPart runat=server></{0}:SampleWebPart>")]

    [XmlRoot(Namespace = "LearnWriteWebPart.Webpart")]

    public class SampleWebPart : WebPart

    {

        private string _Text = "Hello World!";

 

        [WebBrowsable(true), Personalizable(true)]

        public string Text

        {

            get { return _Text; }

            set { _Text = value; }

        }

 

        protected override void Render(System.Web.UI.HtmlTextWriter writer)

        {

            writer.Write(_Text);

        }

 

    }

}在我们建好的spring blog中作如下操作把webpart加入站点中:

 

1、首先把自己写的webpart激活。如下点击populate gallery.

2、在spring blog加载web part,首先点击edit page.

3、再点击add web a part 后,选择我们的samplewebpart.

4、结果如我们所想的一样

接着我们做一个复杂点的,用户登陆web part.要做这样一个web part,我们先要加一个user control,名字命名为LoginUserControl.ascx,

 

代码设计如下:

 

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="LoginUserControl.ascx.cs" Inherits="WebUserControl_LoginUserControl" %>

<style type="text/css">

    .style1

    {

        width: 32%;

        height: 28px;

    }

    .style2

    {

        width: 128px;

    }

</style>

<table class="style1">

    <tr>

        <td class="style2">

            <asp:Label ID="lblUserAccount" runat="server" Text="UserAccount:"></asp:Label>

        </td>

        <td>

            <asp:TextBox ID="txtUserAccount" runat="server" TabIndex = "1"></asp:TextBox>

            <asp:RequiredFieldValidator ID="rfvUserAccount" runat="server"

                ControlToValidate="txtUserAccount" ErrorMessage="用户名不能为空"></asp:RequiredFieldValidator>

        </td>

    </tr>

    <tr>

        <td class="style2">

            <asp:Label ID="lblPassword" runat="server" Text="Password:"></asp:Label>

        </td>

        <td>

            <asp:TextBox ID="txtPassword" runat="server" TextMode="Password" TabIndex="2"></asp:TextBox>

            <asp:RequiredFieldValidator ID="rfvPassword" runat="server"

                ControlToValidate="txtPassWord" ErrorMessage="密码不能为空"></asp:RequiredFieldValidator>

        </td>

    </tr>

    <tr>

        <td class="style2">

             </td>

        <td>

            <asp:Button ID="btnLogin" runat="server" TabIndex="3" onclick="btnLogin_Click"

                Text="Login" />

            <asp:Label ID="lblResult" runat="server" BorderColor="Red" ForeColor="Red"></asp:Label>

        </td>
