我希望建立一个相当简单的插件来计算使用的“单位”数量。剩余。我有两个自定义的成员(父母)bc_learninglicences& (子)bc_llbalance,插件在创建bc_llbalance时触发,另一个用于更新。
bc_llbalance:包含
bc_learninglicense(在父母上查找字段bc_learninglicences / bc_name)
bc_units(本记录使用的单位)
bc_learninglicences:包含
bc_name
bc_unitsquantity(设置为单位总数)
bc_unitsused(这需要在“bc_llbalance”上继承“bc_units”的总和)
bc_unitsremaining(只是bc_unitsquantity - bc_unitsused)
好的,所以我已经包含了我刚刚试图弄清楚如何让bc_unitsused继承总和的代码......
p.s我是开发CRM 2011的新手,只有几周/几个项目经验。
// Obtain the execution context from the service provider.
Microsoft.Xrm.Sdk.IPluginExecutionContext context (Microsoft.Xrm.Sdk.IPluginExecutionContext) serviceProvider.GetService(typeof(Microsoft.Xrm.Sdk.IPluginExecutionContext));
//Extract the tracing service for use in debugging sandboxed plug-ins.
ITracingService tracingService =(ITracingService)serviceProvider.GetService(typeof(ITracingService));
if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)
{
// Obtain the target entity from the input parmameters.
Entity entity = (Entity)context.InputParameters["Target"];
IOrganizationServiceFactory serviceFactory =(IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);
EntityReference a = (EntityReference)entity.Attributes["bc_learninglicense"];// ((EntityReference)targetEntity.Attributes["bc_learninglicense"]).Id;
if (entity.LogicalName == "bc_llbalance")
{
//fetchxml to get the sum total of estimatedvalue
string value_sum = string.Format(@"<fetch distinct='false' mapping='logical'
aggregate='true'><entity name='bc_llbalance'><attribute name='bc_units'
alias='units_sum' aggregate='sum' /><filter type='and'><condition
attribute='bc_learninglicense' operator='eq' value='{0}' uiname=''</filter></entity>
</fetch>", a.Id);
FetchExpression fetch = new FetchExpression(value_sum);
EntityCollection value_sum_result = service.RetrieveMultiple(fetch);
decimal TotalValue = 0;
// decimal TotalValue = 0;
foreach (var c in value_sum_result.Entities)
{
TotalValue = ((Decimal)((AliasedValue)c["value_sum"]).Value);
}
Entity llc = new Entity("bc_learninglicences");
llc.Id = a.Id;
llc.Attributes["bc_unitsused"] = TotalValue;
service.Update(llc);
}
}
所以我认为问题在于与父实体“bc_learninglicences”的连接,“bc_learninglicense”是子实体“bc_llbalance”上的查找字段。
希望这是有道理的:基本上它不起作用

非常感谢您对此解决方案的任何建议或帮助。
感谢您随时帮助我!
我也有一些jscritp加载父表单,它计算子子实体的子网格的总和:这只是为了澄清我需要实现的...这是不够的,因为父表单只更新加载,其中插件bc_learninglicences将在创建bc_llbalance时更新。
function timeout(){
setTimeout(calcUnitTotal, 3000);
}
function calcUnitTotal(){
var grid = document.getElementById('Lines').control;
var ids = gridControl.get_allRecordIds();
var sum = 0;
var cellValue;
for(i = 0; i < ids.length; i++) {
var cellValue = grid.get_selectedRecords('bc_units')[i].value;
var number = Number(cellValue.replace(/[^0-9\.]+/g,""));
sum = sum + number;
}
Xrm.Page.data.entity.attributes.get('bc_unitsused').setValue(sum);
var val1 = Xrm.Page.getAttribute('bc_unitsquantity').getValue();
if(val1 != null && sum != null )
{
var result = val1 - sum;
Xrm.Page.data.entity.attributes.get('bc_unitsremaining').setValue(result);
}
else { alert(val1 + sum + "error: Values not passed for Remaining") }

这里的工作是代码希望它可以帮助某人:

llc.Attributes["bc_unitsused"] = TotalValue;
service.Update(llc);
}
}
}
答案 1 :(得分:0)
错误
The given key was not present in the dictionary
表示您正在尝试检索属性包中不存在的属性。
我猜这行会导致异常:
TotalValue = ((Decimal)((AliasedValue)c["value_sum"]).Value);
这里假设值value_sum
存在,但可能不存在。
测试它的简单方法是编写类似的内容:
if (c.Attributes.ContainsKey("value_sum"))
{
throw new InvalidPluginException("Test - yep no key in the dictionary here!");
}
一旦你能证明这是导致错误的,那么你需要看看为什么会这样。
