update the case status depend on task regarding status

I have this code below. If all the task is reject =>> the case status=>> reject, but i want if i choose other like approve or pending it it gonna do the same with case status. For ex:like i choose csu task status == complete =>> csu case status== complete
Entity target = (Entity)context.InputParameters["target"];
Entity entity = service.Retrieve("task", target.Id, new ColumnSet(true));
EntityReference regardingCaseRef = entity["regardingobjectid"] as EntityReference;
Entity regardingCase = service.Retrieve(regardingCaseRef.LogicalName, regardingCaseRef.Id, new ColumnSet(true));
QueryExpression qeRelatedTasks = new QueryExpression("task");
qeRelatedTasks.ColumnSet = new ColumnSet(true);
qeRelatedTasks.Criteria.AddCondition(new ConditionExpression("regardingobjectid", ConditionOperator.Equal, regardingCaseRef.Id));
EntityCollection relatedTasks = service.RetrieveMultiple(qeRelatedTasks);
if (AllTaskReject(relatedTasks))
{
trace.Trace("status check");
regardingCase["cos_csucasestatus"] = new OptionSetValue(769190006);
trace.Trace("status check 2");
service.Update(regardingCase);
trace.Trace("status check 3");
/* Entity incident = new Entity("incident");
incident.Id = regardingCaseRef.Id;
trace.Trace("1");
incident["cos_csucasestatus"] = new OptionSetValue(769190006);
service.Update(incident);*/
// regardingCase.Attributesk["cos_csucasestatus"] = new OptionSetValue(769190006);
}
}
catch
{
throw;
}
}
}
public bool AllTaskReject(EntityCollection relatedTasks)
{
//check all the the task if rejected continue if on task not rejected do nothing
if (relatedTasks.Entities.All(x => x.GetAttributeValue<OptionSetValue>("cos_csutaskstatus")?.Value == 769190003))

CRM workflow: How to get all the records from a subgrid as a list of entities and perform multi-retrieve

As the title suggests, I do not know how to convert entity.attributes ["subgrid"] as a list of entities, on which to run the multiretrieve:
My code for now:
protected override void Execute(CodeActivityContext executionContext)
{
ITracingService tracingService = executionContext.GetExtension<ITracingService>();
IWorkflowContext context = executionContext.GetExtension<IWorkflowContext>();
IOrganizationServiceFactory serviceFactory = executionContext.GetExtension<IOrganizationServiceFactory>();
IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);
var entity = (Entity)context.InputParameters["Target"];
if (entity.LogicalName != "account")
{
return;
}
var currentAccountId = entity.Id;
try
{
if (!entity.Contains("Subgrid"))
{
return;
}
var itemsOnSubgrid = entity.Attributes["Subgrid"];
if(itemsOnSubgrid == null)
{
return;
}
else
{
//if subgrid exist and is not null
//List of entities needed
}
}
catch (Exception ex)
{
tracingService.Trace("MyWorkflow: {0}", ex.ToString());
throw new InvalidPluginExecutionException(ex.Message);
}
}

As you are writing code in a custom workflow assembly - the entity at this point does not know anything about the form it is being called from, and does not have a "Subgrid" property to allow you to access the related records.
You will need to do a sperate query to retrieve related contacts (as an example) using the target entity's "accountid" property to relate to the contacts' "parentcustomerid" property.

Assume you are looking for a method to get all associated records for a particular record.
If that is the case, I would have written something like this. Hope that helps.
private EntityCollection GetAssociatedRecords(string relationshipName, string relatedEntityName, string entityName, Guid entityId,OrganizationService service)
{
EntityCollection result = null;
try
{
QueryExpression query = new QueryExpression();
query.EntityName = relatedEntityName;
query.ColumnSet = new ColumnSet(false);
Relationship relationship = new Relationship();
relationship.SchemaName = relationshipName;
relationship.PrimaryEntityRole = EntityRole.Referencing;
RelationshipQueryCollection relatedEntity = new RelationshipQueryCollection();
relatedEntity.Add(relationship, query);
RetrieveRequest request = new RetrieveRequest();
request.RelatedEntitiesQuery = relatedEntity;
request.ColumnSet = new ColumnSet(true);
request.Target = new EntityReference
{
Id = entityId,
LogicalName = entityName
};
RetrieveResponse response = (RetrieveResponse)service.Execute(request);
RelatedEntityCollection relatedEntityCollection = response.Entity.RelatedEntities;
if (relatedEntityCollection.Count > 0)
{
if (relatedEntityCollection.Values.Count > 0)
{
result = (EntityCollection)relatedEntityCollection.Values.ElementAt(0);
}
}
}
catch (Exception exception)
{
throw exception;
}
return result;
}
In that based on the role of the other entity change the Primary Entity Role between Referencing and Referenced.
Hope that helps. Let me know if my assumption is wrong.

Can't save record using Entity Framework

My objects will not save no matter what I do they will fetch and get info and make a new record but not update.
This is the code that details with getting existing patient and then modifying the record setting the state then calling save change this is cracking my head the last three hours what is going wrong. I was told you had to change the entity state of an object before it would no if to save but when i try to attach it it says its already attached
Appointment _appointment = new Appointment();
int errorCount = 0;
Patient _patient = SourceDal.getPatientByPatientNewId(Convert.ToInt32(txtPatientId.Text));
_patient.SSN = txtSSN.Text;
_patient.FirstName = txtPatientFirstName.Text;
_patient.LastName = txtPatientLastName.Text;
_patient.Middle = txtPatientMiddle.Text;
_patient.AddressOne = txtPatientAddressOne.Text;
_patient.City = txtPatientCity.Text;
_patient.State = txtPatientState.Text;
_patient.ZipCode = txtPatientZip.Text;
_patient.HomePhone = txtPatientHomePhone.Text;
_patient.WorkPhone = txtPatientWorkPhone.Text;
_patient.CellPhone = txtPatientCellPhone.Text;
if (rBtnHomePhone.Checked == true)
// _patient.ApptPhone = txtPatientHomePhone.Text;
if (rBtnHomePhone.Checked == true)
// _patient.ApptPhone = txtPatientHomePhone.Text;
if (rBtnWorkPhone.Checked == true)
// _patient.ApptPhone = txtPatientWorkPhone.Text;
_patient.BirthDate = dtBirthDate.DateTime;
_patient.emailAddress = txtPatientEmail.Text;
_patient.Race = Convert.ToInt32(dpRace.SelectedValue);
_patient.Ethnicity =Convert.ToInt32(dpEthnicity.SelectedValue);
_patient.Language = Convert.ToInt32(dpLanguages.SelectedValue);
if (dpGender.Text == "")
{
dpGender.Focus();
errorCount = 1;
lblGenderRequired.Text = "* Gender is required.";
}
else
{
errorCount = 0;
lblGenderRequired.Visible = false;
}
_patient.Gender = "M";
_patient.PatientID = txtPatientId.Text;
SourceDal.SourceEntities.Patients.Attach(_patient);
SourceDal.SourceEntities.Patients.Context.ObjectStateManager.ChangeObjectState(_patient, EntityState.Modified);
SourceDal.SourceEntities.SaveChanges();
The error I get is
An unhandled exception of type 'System.InvalidOperationException' occurred in System.Data.Entity.dll
Additional information: An entity object cannot be referenced by multiple instances of IEntityChangeTracker.
Edit 2:
Code to show my function getPaitnetByPatineyNewId
public Patient getPatientByPatientNewId(int newId)
{
Patient patient = new Patient();
if (newId == -1)
{
patient = new Patient();
}
else
{
patient = SourceEntities.Patients
.Where(w => w.ID == newId)
.FirstOrDefault();
}
return patient;
}

I think you have some issues with proper separation of concerns within your DAL, but for the short solution, you should only add (and not attach) if it's a new entity
if (_patent.PatentId == 0)
{
_patient.PatientID = txtPatientId.Text; // If you're using an identity column, remove this line. I would also strongly suggest not letting the user change this...
SourceDal.SourceEntities.Patients.Add(_patient);
}

For Anyone else the above scenarios did not work for me so this is what I had to do. I put a flag on my forms isUpdate and check that on the save button then if save call similar to below then if add just call savechanges and its now working thank you for everyone help hope this help someone.
public void SaveProviders(Provider _providers)
{
try
{
using (var ctx = new SMBASchedulerEntities(this.Connectionstring))
{
ctx.Providers.Add(_providers);
ctx.Entry(_providers).State = System.Data.Entity.EntityState.Modified;
ctx.SaveChanges();
}
}
catch (DbEntityValidationException e)
{
foreach (var eve in e.EntityValidationErrors)
{
Console.WriteLine("Entity of type \"{0}\" in state \"{1}\" has the following validation errors:",
eve.Entry.Entity.GetType().Name, eve.Entry.State);
foreach (var ve in eve.ValidationErrors)
{
Console.WriteLine("- Property: \"{0}\", Error: \"{1}\"",
ve.PropertyName, ve.ErrorMessage);
}
}
throw;
}
}

Delete message plug-in not firing Dynamics CRM

I have a parent entity and child entity. I'm creating a plugin to count number of child entities for each parent entity and display the number in noOfProduct field in parent entity. So every time when I created a new child entity, the value of number in noOfProduct will be increment to 1. But when I deleted the child entity, my plugin is not triggering, hence the value remain the same.
I registered my plugin,
step: create
primary entity: child_entity
event_pipeline: post-operation
synchronous

You forgot to call the method queryOppProdOnDel.
When you register your Plugin assembly & Step on Delete message, replace the below snippet in your code.
//triggered upon delete message
if (context.MessageName == "Delete")
{
Guid oppProdId = targetEntity.Id;
// retrieve oppid guid
Entity oppProd = new Entity("child_entity");
ColumnSet columns_ = new ColumnSet(new string[] { "lookup_fieldtoParent" });
oppProd = service.Retrieve(oppProd.LogicalName, oppProdId, columns_);
Guid oppId = new Guid();
oppId = ((EntityReference)oppProd["lookup_fieldtoParent"]).Id;
//throw new InvalidPluginExecutionException(
queryOppProdOnDel(service, oppId, oppProdId);
}
Update:
This line is missing in queryOppProdOnDel:
opportunity["new_noofproducts"] = noOfProduct;

Couple of points:
step: create You should register on delete.
Pretty sure post-image is not supported on delete. You need to use pre's. "The create operation doesn’t support a pre-image and a delete operation doesn’t support a post-image."
Your basic design has a flaw. If lots of changes occur at the same time, they could all execute concurrently on seperate threads, this means the count could be incorrect in some circumstances.

Get the list of notes

How to obtain the list (or e.g. collection) of guids of all notes associated with current entity?
I know that it is in some way connected with service.Retreive(...), but can't make working code.
Attach 1:
public void Execute(IServiceProvider serviceProvider)
{
Entity entity = null;
var context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
if (entity.Contains("new_parentopportunity"))
{
try
{
IOrganizationServiceFactory factory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
IOrganizationService service = factory.CreateOrganizationService(context.UserId);
Guid projectGuid = entity.Id;
Guid oppGuid = ((EntityReference)entity["new_parentopportunity"]).Id;
for (int i = 0; i < 100; i++) //Instead of 100, I'll place obtained collection.Length
{
Entity opp = service.Retrieve("", oppGuid, new Microsoft.Xrm.Sdk.Query.ColumnSet(true)); //RETREIVE ENTITY NOTE HERE
var temop = CreateNoteAttachment(opp);
service.Create(temp);
}
}
catch (Exception ex)
{
throw new InvalidPluginExecutionException("An error occurred in the plug-in.", ex);
}
}
}
private Entity CreateNoteAttachment(Entity oppNote)
{
//some code here
}
Update 1:
I also write it in queries, can you look at this, whethere everything fine there?
PasteBin

Two ways to query for related notes:
Early Bound:
var notes =
service.AnnotationSet.Where(annotation => annotation.Opportunity_Annotation.Id == entity.Id)
.Select(annotation => annotation.Id)
.ToList();
FetchXml:
var fetchXml = string.Format("<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='false'>" +
"<entity name='annotation'>" +
"<attribute name='annotationid' />" +
"<filter type='and'>"+
"<condition attribute='objectid' operator='eq' value='{0}'/>"+
"</filter>"+
"</entity>" +
"</fetch>", entity.Id);
var response = service.RetrieveMultiple(new FetchExpression(fetchXml));
var notes = response.Entities;
