Simple webpart Creation

• Create a C#-> Sharepoint->Webpart project in vs2008(sharepoint developer tool 9.0 need to be preinstalled)
• Select deploy option: to GAC or to Bin
• Put deployment path on debug property of project
• Deploy to server
• At this point, the web part component should be shown up in web page dialog of server.

 

 

SP Webpart

• Can use quickpart tool to deploy ascx control to sp as webpart (issue: can not be used if want to call other controls in pages like webpartmanager because in ascx can not get instance of webpartmanager)
  • deploy quickpart.dsp to projecct
  • copy .ascx to wprecourse folder
  • copy .dll to bin folder

Webpart Debug

• Debug –>Attach to process (wcwp.exe : process of sp)

Two Webparts Sample:

 

Need to put IPostBackEventHandler to cause post back event by script.

      • 下载StsAdm.AjaxifyMoss.zip并解压，执行deploy.cmd后执行upgrade.cmd
      • run following on cmd window:
        • "C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\bin\stsadm" -o addajax35 -url http://dayang-49u5xli7:39329/sites/TestWorkStation/
        • Cmd detail :

          功能  使用例

          add asp.net ajax to web.config
          stsadm -o addajax -url http://your.moss.webapplication

          remove asp.net ajax from web.config
          stsadm -o removeajax -url http://your.moss.webapplication

          add .Net 3.5 ajax to web.config
          stsadm -o addajax35 -url http://your.moss.webapplication

          remove .Net 3.5 ajax from web.config
          stsadm -o removeajax35 -url http://your.moss.webapplication
• Code:
  • Create a webpart project
  • Add System.Web.Extensions reference which includes scriptmanager and update panel
  • Sample code (note : oninit /createchildcontrols)

• QuickPart Webpart Development
• Run InstallSolution.bat on server of Quickpart.zip(with quickpart.wsp) which will deploy quickpart.wsp to sp server
• Deploy quickpart to specified site
• Admin site -->全局配->解决方案管理-->部署解决方案—>Quickpart
• Active quickpart in site
• Site-->网站集管理—>Active quickpart
• Create a sharepoint project and add a web user control(.ascx)  componet(can not add directly but copy/paste from an asp.net applicaton)
• Set the start browser with url with destination site
• on build events of project , adding the following cmd(which will copy *.dll to “bin” folder and *.ascx” to “wpresource” .

copy "$(TargetPath)"  C:\Inetpub\wwwroot\wss\VirtualDirectories\39329\bin  
copy "$(ProjectDir)*.ascx"  C:\Inetpub\wwwroot\wss\VirtualDirectories\39329\wpresources
