I got requirement to integrate CRM with sharepoint, where I need to update sharepoint list fields from crm opportunity fields. In order to send opportunity information to sharepoint I wrote a plugin and used sharepoint Lists.asmx and sitedata.asmx webservice to update sharepoint list. I use below code to update sharepoint list

//create list object
SharepointWS.Lists OpportunityList = new SharepointWS.Lists();
OpportunityList.Credentials = new System.Net.NetworkCredential(“User”, “Password”, “Domain”);

OpportunityList.Url = “http://tim/news/adsales/groups/domestic/_vti_bin/Lists.asmx”;

//Get list ID
XmlNode _List = OpportunityList.GetList(“List Name”);
string _ListID = _List.Attributes[“ID”].Value;

XmlDocument _Batchdoc = new XmlDocument();
XmlElement _BatchElement = _Batchdoc.CreateElement(“Batch”);
_BatchElement.SetAttribute(“OnError”, “Return”);
_BatchElement.SetAttribute(“ListVersion”, “1”);
string UpdateCmd = “” +
“” + _SharepointViewID + “”+
“” + _AccountName + “”+
“” + _OpportunityType + “” +
“” + _OpportunityStatus + “”;

XmlDocument _UpdateCmdDoc = new XmlDocument();
_UpdateCmdDoc.LoadXml(UpdateCmd);
_BatchElement.InnerXml = _UpdateCmdDoc.OuterXml;
XmlNode _Result;
_Result = OpportunityList.UpdateListItems(_ListID, _BatchElement);
