Dynamics CRM 2011编程系列（1）：系统实体状态更新

来源：互联网发布：百度软件手机助手编辑：程序博客网时间：2024/06/06 00:26

   我们在更改系统实体的状态时，不能直接update实体的statecode,需要引用Execute来执行请求，然后更新实体的状态，在此举例商机的赢单，分别用插件Plguin和SOAP的方式执行。查询SDK，赢单需要用WinOpportunityRequest请求，插件形式更新代码如下：

Entity target = new Entity() { LogicalName = "opportunityclose" };target["opportunityid"] = new EntityReference() { LogicalName = "opportunity", Id = entity.Id };WinOpportunityRequest request = new WinOpportunityRequest();request.OpportunityClose = target;request.Status = new OptionSetValue(3);service.Execute(request);

   更新商机为赢单后，查看商机的状态，导航栏保存等按钮即变为灰色，页面无法进行更改操作，即显示该商机已结束。   SOAP方式更新代码，可以采用SDK现有的工具SOAPLogger生成报文，该工具打包在Dynamics CRM 2011 SDK中的\samplecode\cs\client（具体报文工具使用情况请看下一篇： Dynamics CRM 2011编程系列（2）：使用SOAPLogger抓取报文），客户端添加按钮后调用方法更新商机。SOAP报文如下：

    function ChangeStatus(entityName, entityId, stateCode, statuscode) {    // create the request    var request = "<s:Envelope xmlns:s=\"http://schemas.xmlsoap.org/soap/envelope/\">";    request += "<s:Body>";    request += "<Execute xmlns=\"http://schemas.microsoft.com/xrm/2011/Contracts/Services\" xmlns:i=\"http://www.w3.org/2001/XMLSchema-instance\">";    request += "<request i:type=\"b:WinOpportunityRequest\" xmlns:a=\"http://schemas.microsoft.com/xrm/2011/Contracts\" xmlns:b=\"http://schemas.microsoft.com/crm/2011/Contracts\">";    request += "<a:Parameters xmlns:c=\"http://schemas.datacontract.org/2004/07/System.Collections.Generic\">";    request += "<a:KeyValuePairOfstringanyType>";    request += "<c:key>OpportunityClose</c:key>";    request += "<c:value i:type=\"a:Entity\">";    request += "<a:Id>" + entityId + "</a:Id>";    request += "<a:LogicalName>opportunity</a:LogicalName>";    request += "<a:Name i:nil=\"true\" />";    request += "</c:value>";    request += "</a:KeyValuePairOfstringanyType>";    request += "<a:KeyValuePairOfstringanyType>";    request += "<c:key>State</c:key>";    request += "<c:value i:type=\"a:OptionSetValue\">";    request += "<a:Value>" + stateCode + "</a:Value>";    request += "</c:value>";    request += "</a:KeyValuePairOfstringanyType>";    request += "<a:KeyValuePairOfstringanyType>";    request += "<c:key>Status</c:key>";    request += "<c:value i:type=\"a:OptionSetValue\">";    request += "<a:Value>" + statuscode + "</a:Value>";    request += "</c:value>";    request += "</a:KeyValuePairOfstringanyType>";    request += "</a:Parameters>";    request += "<a:RequestId i:nil=\"true\" />";    request += "<a:RequestName>SetState</a:RequestName>";    request += "</request>";    request += "</Execute>";    request += "</s:Body>";    request += "</s:Envelope>";    //send set state request    $.ajax({        async: false,        type: "POST",        contentType: "text/xml; charset=utf-8",        datatype: "xml",        url: Xrm.Page.context.getServerUrl() + "/XRMServices/2011/Organization.svc/web",        data: request,        beforeSend: function (XMLHttpRequest) {            XMLHttpRequest.setRequestHeader("Accept", "application/xml, text/xml, */*");            XMLHttpRequest.setRequestHeader("SOAPAction", "http://schemas.microsoft.com/xrm/2011/Contracts/Services/IOrganizationService/Execute");        },        success: function (data, textStatus, XmlHttpRequest) {            alert("The Entity Status has been changed");        },        error: function (XMLHttpRequest, textStatus, errorThrown) {            alert(errorThrown);        }    });}
