SQL 2005自己提供的报表查看web part功能比较简单，不太适合中国人对报表界面的复杂要求。

这个WebPart的主要功能是提供新的参数录入方式，如日期型改用日历来选择。

第一步：建立一个新的web part

新建一个的dll工程BARreportWebPart

将class1.cs重命名为BARreportWebPart。

增加对System.web的引用，并将类BARreportWebPart从webpart派生。重写Render方法，控制自己的输出。
using System;
using System.Collections.Generic;
using System.Text;
using System.Web.UI;
using System.Web.UI.WebControls.WebParts;

namespace BARreportWebPart
{
public class BARreportWebPart : WebPart
{

        protected override void Render(System.Web.UI.HtmlTextWriter writer)
        {
            writer.Write("This web part is a report view for SQL 2005 reporting services :)");
        }
     }
}

web part需要强名来注册到GAC中，用命令行 sn -k BARreportWebPart.snk 生成强名文件，在工程属性的签名页指定使用该文件作强名。

web part注册还需要两个注册信息文件,后缀为webpart和dwp。
新建一个xml文件，重命名为BARreportWebPart.webpart，内容为
<?xml version="1.0" encoding="utf-8"?>
<webParts>
<webPart xmlns="http://schemas.microsoft.com/WebPart/v3">
    <metaData>
      <type name="BARreportWebPart.BARreportWebPart, BARreportWebPart, Version=1.0.0.0, Culture=neutral, PublicKeyToken=6b51eec99acee804" />
      <importErrorMessage>Cannot import this Web Part.</importErrorMessage>
    </metaData>
    <data>
      <properties>
        <property name="Title" type="string">BARreportWebPart</property>
      </properties>
    </data>
</webPart>
</webParts>
新建一个xml,重命名为BARreportWebPart.dwp，内容为
<?xml version="1.0" encoding="utf-8"?>
<WebPart xmlns="http://schemas.microsoft.com/WebPart/v2" >
<Title>BAR reports Web Part</Title>
<Description>The BAR report viewer web part</Description>
<Assembly>BARreportWebPart, Version=1.0.0.0, Culture=neutral, PublicKeyToken=6b51eec99acee804</Assembly>
<TypeName>BARreportWebPart.BARreportWebPart</TypeName>

</WebPart>

到现在，一个没有功能的web part已经完成了。下一步，我们需要把它配置到sharepoint站点上。

第二步配置sharepoint，注册这个web part

编译工程，将文件拷贝到sharepoint服务器的GAC中。

修改sharepoint根站点的web.config（C:/Inetpub/wwwroot/wss/VirtualDirectories/80/web.config）,将BARreportWebPart的dll添加到SafeControls中
<SafeControls>
.......
<SafeControl Assembly="BARreportWebPart, Version=1.0.0.0, Culture=neutral, PublicKeyToken=6b51eec99acee804" Namespace="BARreportWebPart" TypeName="*" Safe="True" />
</SafeControls>

打开sharepoint站点，进入根站点的Site Settings，在Galleries中选择web part进入Web Part Gallery。
选择upload document,上传BARreportWebPart.webpart文件。一个新的web part被注册了。

需要重新启动IIS让这些设置生效

开发自己的SQL2005报表查看SharePoint WebPart（二）

在（一）中，已经完成了一个sharepoint Web part的开发和部署。但是我们的web part还没有任何功能。现在，我们要开始将SQL reporting的报表显示功能加进来了。
访问SQL reporting报表有很多方法，这里我们选用的是调用Web service的方式。
在工程中增加对SQL reporting service的引用, http://ctc-bar:81/ReportServer/reportservice.asmx(ctc-bar:81是报表服务器名称和段口号)
为了简化对报表服务器的调用，我们新建一个ReportAdapter类负责对web service的调用。
using System;
using System.Collections.Generic;
using System.Text;

namespace BARreportWebPart
{
    public class ReportAdapter
    {
        ReportingServer.ReportingService ReportSvr = null;
        string reportServerURL = null;
        string reportPath = null;
        string format = "HTML4.0";
        string zoom = "100";
        string deviceInfo = "<DeviceInfo></DeviceInfo>";
        string encoding = null;
        string mimeType = null;
        ReportingServer.ParameterValue[] outParameters = null;
        ReportingServer.Warning[] warnings = null;
        string[] streamIDs = null;

        public ReportAdapter(string serverURL,string path)
        {
            reportServerURL = serverURL;
            reportPath = path;
            ReportSvr = new ReportingServer.ReportingService();
            ReportSvr.Url = reportServerURL;
            ReportSvr.Credentials = System.Net.CredentialCache.DefaultCredentials;
        }

        public ReportingServer.ReportParameter[] GetParameters()
        {
            return ReportSvr.GetReportParameters(reportPath, null, false, null, null);
        }

        public byte[] RenderReport(ReportingServer.ParameterValue[] parameterValues)
        {
            return ReportSvr.Render(reportPath, format, null, deviceInfo, parameterValues, null, null, out encoding, out mimeType, out outParameters, out warnings, out streamIDs);
        }
    }
}

这个类的构造函数用来指定要访问的报表serverURL是服务器的地址,path是报表的路径
GetParameters()可以返回报表的参数，我们可以自己构造参数输入的UI控件。
RenderReport用来返回查询报表的结果。

然后，我们在web part的render方法中调用ReportAdapter来查询报表
using System;
using System.Collections.Generic;
using System.Text;
using System.Web.UI;
using System.Web.UI.WebControls.WebParts;

namespace BARreportWebPart
{
    public class BARreportWebPart : WebPart
    {
        public BARreportWebPart()
        {
        }

        protected override void Render(System.Web.UI.HtmlTextWriter writer)
        {
            string reportServerURL = "http://ctc-bar:81/ReportServer/ReportService.asmx";
            string reportPath = "/BARreports/EBCdetailList";

            ReportAdapter rsAdapter = new ReportAdapter(reportServerURL, reportPath);
            ReportingServer.ReportParameter[] parameters = rsAdapter.GetParameters();
            ReportingServer.ParameterValue[] parameterValues = null;
            if (parameters.Length > 0)
            {
                parameterValues = new ReportingServer.ParameterValue[parameters.Length];
                for (int i = 0; i < parameters.Length; i++)
                {
                    parameterValues[i] = new ReportingServer.ParameterValue();
                    parameterValues[i].Name = parameters[i].Name;
                    parameterValues[i].Label = parameters[i].Prompt;
                }
                parameterValues[0].Value = "2007-1-1";
                parameterValues[1].Value = "2007-3-1";
            }
            System.Text.Encoding enc = System.Text.Encoding.UTF8;
            byte[] result = rsAdapter.RenderReport(parameterValues);
            string htmlResult = enc.GetString(result);
            //htmlResult = htmlResult.Replace(reportServerURL.Replace("/ReportService.asmx", "?"), "http://" & Request("SERVER_NAME") & Request("SCRIPT_NAME") & "?Report=");
            writer.Write(htmlResult);
        }
     }
}

开发自己的SQL2005报表查看SharePoint WebPart（三）

我们在（一）里完成了web part的实现
在（二）里完成了通过调用SQL2005 reporting services的web service，查询并显示报表
现在，我们要给Web part增加属性来设置报表服务器的地址和报表路径
首先，为了能够在SharePoint中设置属性，需要增加对Microsoft.SharePoint的引用，原来我们的 BARreportWebPart是从System.Web.UI.WebControls.WebParts.WebPart继承的，现在要改为从 Microsoft.SharePoint.WebPartPages.WebPart继承。否则你在Sharepoint web part属性设置里面看不到你的自定义属性
然后，增加两个字符类型的属性：ReportServerURL，ReportPath。具体的attribute设置请参考
如何给Web part增加自定义属性Creating a Web Part with Custom Properties(http://msdn2.microsoft.com/en-us/library/ms948927.aspx)
这是最后的代码

            set {
                _reportPath = value;
            }

开发自己的SQL2005报表查看SharePoint WebPart（四）

这一节，我们给Web part增加报表查询参数。为了演示，这里只增加两个查询参数：开始时间和结束时间。这两个参数都是日期型的数据，为了方便用户操作，我使用了client端的日历脚本来实现日期输入。

与上一节相比，我们需要增加两部分工作

第一步：构造日期输入控件

我的页面布局大概是这样的：

From [_txtStartDate] [_btnStartDate]	To [_txtStartDate] [_btnEndDate]
[_cmdOK]

参数输入区

报表显示区

状态来栏

为了加入参数，我在构造函数里创建了一组table，将控件分别加入到各单元格中。

下面为代码

protected string _reportServerURL = "" ; // = "http://ctc-bar:81/ReportServer/ReportService.asmx";

protected string _reportPath = "" ; // = "/BARreports/EBCdetailList";

// UI controls

protected HtmlInputText _txtStartDate = BuildTextBox( "txtStartDate" ); protected HtmlButton _btnStartDate = new HtmlButton (); protected HtmlInputText _txtEndDate = BuildTextBox( "txtEndDate" ); protected HtmlButton _btnEndDate = new HtmlButton (); protected Button _cmdOK = new Button (); protected HtmlGenericControl ReportView = new HtmlGenericControl (); protected Label _lblStatus = new Label (); protected Label _lblError = new Label (); protected HtmlInputHidden ctrlPrefix = new HtmlInputHidden (); protected string canlander_JSP = "" ;

#region

{

canlander_JSP = BARreportWebPart.Properties.

initailize the web controls public BARreportWebPartClass() Resources .Canlander_JSP; //<input type=hidden id="ctrlPrefix" name="ctrlPrefix" value='<asp:Literal Runat=server ID=ctrlPrefix></asp:Literal>'>

}

/// <returns> A TextBox </returns>

{

t.ID = id;

}

private static HtmlInputText BuildTextBox( string id) HtmlInputText t = new HtmlInputText (); return t;

#endregion

第二步：注册javascript脚本来实现日历输入。

为了更加友好的用户操作，需要利用javascript来实现日期输入。javascript脚本很长，所以我把脚本保存在资源文件中，这样，对脚本的修改大大方便了。具体原理参见我的另一篇文章http://blog.youkuaiyun.com/yanwei100/archive/2007/03/15/1530528.aspx

由于脚本是运行在一个自定义web控件中，所以需要解决ClientID的问题，具体方法参考我的另外一篇文章。

下面是代码

#region

{

RegisterJSP();

regist Java script protected override void OnLoad( EventArgs e) // set ctrlPrefix's value

string name = this .ClientID; string [] elm = ctrlPrefix.ClientID.Split( '_' ); //get an array of values

ctrlPrefix.Value = ctrlPrefix.ClientID.Replace(elm[elm.Length - 1],

"" ); //get the last element and replace from the id

}

{

base .OnLoad(e); void RegisterJSP() //read jsp file from resource

String csname1 = "CalendarScript" ; Type cstype = this .GetType(); // Get a ClientScriptManager reference from the Page class.

ClientScriptManager cs = Page.ClientScript; // Check to see if the client script is already registered.

{

cs.RegisterClientScriptBlock(cstype, csname1, canlander_JSP,

}

if (!cs.IsClientScriptBlockRegistered(cstype, csname1)) false ); //add the getprefix function

strbld.Append(

{

cs.RegisterClientScriptBlock(cstype, csname2, strbld.ToString(),

}

{

ClientID_txtStartDate = ctrl.ClientID;

}

{

_btnStartDate = (

}

{

_btnStartDate.Attributes.Add(

}

StringBuilder strbld = new StringBuilder (); "<script language ='javascript' type='text/javascript' >" ); "function getCrtlPrefix() {" ); "var prefix; " ); "var objCrtlPrefix = document.getElementById('" + ctrlPrefix.ClientID + "');" ); "if (objCrtlPrefix)" ); "prefix = objCrtlPrefix.value;" ); "return prefix;}" ); "function GetObject(ctrlName) {" ); "var prefix = getCrtlPrefix();" ); "var objCrtl = document.getElementById(prefix + ctrlName);" ); "if (objCrtl)" ); "return objCrtl;" ); " else " ); " alert('not found!');} " ); "</script>" ); string csname2 = "getCrtlPrefixScript" ; if (!cs.IsClientScriptBlockRegistered(cstype, csname2)) false ); protected override void OnPreRender( EventArgs e) string ClientID_txtStartDate= "" ; HtmlButton _btnStartDate = null ; foreach ( Control ctrl in Controls[0].Controls[0].Controls[0].Controls[0].Controls[0].Controls[0].Controls) if ( "txtStartDate" == ctrl.ID) if ( "btnStartDate" == ctrl.ID) HtmlButton )ctrl; if ( null != _btnStartDate) "onclick" , "show_cele_date(this,'','',document.getElementById('" + ClientID_txtStartDate + "'))" ); base .OnPreRender(e);

#endregion

最后，将用户输入的日期加入到web service的查询参数中：

{

writer.Write(

{
