Creating Item in SP List oDat.Type for People attribute

I need to create an item with Person/People field.
I am able to populate fields like Title, DateTime, TextField as seen below, but I am not able to populate Person field at all.
I have tried sending Display Name, User ID and UPN.
var fieldValueSet = new FieldValueSet();
fieldValueSet.AdditionalData = new Dictionary<string, object>();
fieldValueSet.AdditionalData.Add("Title#odata.type", "Edm.String");
fieldValueSet.AdditionalData.Add("Title", task.Title);
fieldValueSet.AdditionalData.Add("Plan#odata.type", "Edm.String");
fieldValueSet.AdditionalData.Add("Plan", plan.Title);
fieldValueSet.AdditionalData.Add("Assigned#odata.type", "Edm.String");
fieldValueSet.AdditionalData.Add("Assigned", assignee.UserPrincipalName);
fieldValueSet.AdditionalData.Add("DueDate#odata.type", "Edm.String");
fieldValueSet.AdditionalData.Add("DueDate", task.DueDateTime);
var listItem = new ListItem
{
Fields = fieldValueSet
};
await graphServiceClient.Sites["SPURL:/sites/ITOddeleni:"].Lists["ListName"].Items
.Request()
.AddAsync(listItem)

Does your user principal name look like an email? (e.g. some.person#yourtenant.onmicrosoft.com). If that is the case then you should probably try to convert it to a sharepoint-claim version: i:0#.f|membership|some.dude#yourtenant.onmicrosoft.com.
If you have an authenticated ClientContext in your app, then you could resolve the username by calling the SharePoint utility:
Utility.ResolvePrincipal(context, context.Web, userEmail, PrincipalType.User, PrincipalSource.All, null, true);
If you don't have a context then you can try and combine strings (not as robust, but should work as well).
This answer suggests that you should try and set the LookupId value for the field (sorta the same way you set user values using the SharePoint's REST api):
var assigneeLookupId = // Get the assignee's user id on the site (wssid)
fieldValueSet.AdditionalData.Add("AssignedLookupId#odata.type", "Edm.Int32");
fieldValueSet.AdditionalData.Add("AssignedLookupId", assigneeLookupId);
The following schema would allow you to insert multiple person values:
SOLUTION
After help from comments i got this answer which worked
{
"AssignedLookupId#odata.type" : "Collection(Edm.Int32)"
"AssignedLookupId": [1,2,3]
}
This approach is in line with the way MS Graph returns values for Lookup fields.

Copy a text field data into a look field type

I am new in coding world :) it would be helpful if somebody can help me with my below query.
We have created two custom entity called Sector and Sub sector which are having an 1:N relationship with Account. Since they are relation fields hence they are lookup type and populated on the Account form.
On another part, we have InsideView( 3rd party tool) integrated with our Contact and account form. We have mapped certain fields from Inside view with CRM fields to update the data from the inside view when it is being synced however Inside view does not support Lookup type field hence we cannot map lookup field type data.
We discovered this barrier recently when we tried to map our custom entity (sector and Subsector) with inside view. Since we cannot map lookup field type we thought to have two text field instead and map it with Inside view. Once data is synced these two text fields will get filled out with the sector and subsector name.
Now, we want to copy information from text fields to the lookup field (custom fields Sector and Sub sector)
thanks in advance for your help :)

I am not understanding your requirement but you can fill a lookup field with some text.
Use following code:
function setLookupField() {
var context = Xrm.Page.context;
var UserID = context.getUserId();// your id
var UserName=context.getUserName();//your text
var lookupData = new Array();
var lookupItem = new Object()`enter code here`;
//Set the GUID
lookupItem.id = UserID;
//Set the name
lookupItem.name = UserName;
lookupItem.entityType = "systemuser";// entity name of lookup
lookupData[0] = lookupItem;
//If existing value is empty, then set new value
var existingValue = Xrm.Page.getAttribute("new_usercreatedby").getValue();
if (existingValue === null) {
Xrm.Page.getAttribute("new_usercreatedby").setValue([{
id: UserID,
name: UserName,
entityType: "systemuser"
}]);
} else {
return;
}
}

Create a computed field using Entity Framework 6

Consider the following model for a EF 6 entity:
Id (int, nullable:false, identity: true)
Name (string)
Number (string).
I want number to persisted as combination of letter and id field. For example if during insert id valuse is going to be 1, I want number to be A00000001. I tried using DatabaseGenerated attribute on Number but that did not work. Problem is at time of insert EF will not know what identity value is. Is there a way to define a trigger to do so or is there some other method I can achieve this.
Thanks!

If you don't need to save the computed field to the database and are using POCOs for Entities you can just define an unmapped field like this:
[NotMapped]
public string Number
{
get { return Name + Id.ToString(); }
}

Try first inserting the item to the database:
Item myItem = new Item(){Name = "MyName"};
dbcontext.Items.Add(myItem);
dbcontext.SaveChages();
Then bring the item from the database and update it:
Item insertedItem = dbcontext.Items.Single(i => i.Id == myItem.Id);
insertedItem.Number = insertedItem.Name + insertedItem.Id.toString();
dbcontext.SaveChages();

How to join tables using include with entity SQL

I will try to describe my issue in details.I have the following scenario.
1.) I have 3 tables : business, customoffice(Custom Office) and cusdesc(custom office description)
The relationship is that a business has on customoffice and one customoffice has many cusdesc.
The table business has a field customofficeno which is a foreign key to the field cuscode of the customoffice table.The table cusdesc has a field cuscode which is a foreign key to the field cuscode of the customoffice table.
The objective is to select a business including the custom office and custom office description using entity framework.
2.) Code
I have a procedure FillData which fills a datagrid. My objective is to display fields from the 3 tables. I managed to display data from tables "Business" and "Customoffice" but i need to display the description of a custom office via table "cusdesc" and be more specific the field "CSNAME".
3.) My issue is that when I include the ("CUSTOMSOFFICE.CUSDESC") the results do not contain data from table "CUSDESC" but only how many records much the criteria so I cannot access the field "CSNAME"
Hereafter is the procedure:
using (var _context = new ReftabEntities())
{
try
{
SetGlobalValues();
ObjectQuery<BUSINESS> q_business = _context.BUSINESS.Where("it.BUSINESSNO=" + int.Parse(pv_businessno)).Where(string.Format("(it.BUSINESSSTART <= DATETIME'{0:yyyy-MM-dd HH:mm}') and (it.BUSINESSCLOSED >= DATETIME'{0:yyyy-MM-dd HH:mm}')", pv_date)).Include("CUSTOMSOFFICE").Include("CUSTOMSOFFICE.CUSDESC");
gvBusinessList.Caption = "Total records selected: " + q_business.Count();
gvBusinessList.DataSource = q_business;
gvBusinessList.DataBind();
}
catch (Exception e)
{
errorPopup.Text = e.Message;
errorPopup.ShowOnPageLoad = true;
}
finally
{
_context.Dispose();
}
}
}
Can you please give a hint what I do wrong.
Thanks in advance.

The Include operator just asks EF to load a related entity with the query. If you don't use "Include", EF will only extract the properties of BUSINESS and will not extract the properties of the CUSTOMSOFFICE. There is no need for the "Include("CONSOMSOFFICE.CUSDESC")" since you already loaded the entire CUSTOMSOFFICE entity in the first Include.
I see that you're binding the result to the grid view, and if I understand correctly, the issue is that the "CUSTOMSOFFICE.CUSDESC" is not being displayed in the gridview. I believe this is because the gridview tries to render its representation of the "CUSTOMSOFFICE" object itself, since that's the direct property of the items you are binding. To have more control over the "columns" of your gridview, I suggest using LINQ to transform the results of your query into what you explicitly want to display.
I am assuming that BUSINESSNO, BUSINESSSTART, and BUSINESSCLOSED are properties of your Business entity itself, and that BUSINESSNO is the Primary Key. Let me rewrite your query into this:
var q_business = _context.BUSINESS.Include(b=>b.CUSTOMSOFFICE)
.Where(p => p.BUSINESSNO == int.Parse(pv_businessno)
&& p.BUSINESSSTART <= DateTime.Parse(pv_date)
&& p.BUSINESSCLOSED >= DateTime.Parse(pv_date) )
.FirstOrDefault();
This query would extract the details of the Business (including the related CUSTOMSOFFICE details) that matches the given pv_businessno and falls within your date criteria. But you can't bind this to your gridview yet because you might encounter the same problem where the CUSTOMSOFFICE.DESC is not displayed. To ensure proper display, you must identify what properties you want to include. For example, if you only want to display the set of properties below:
BUSINESS.BUSINESSNO
BUSINESS.BUSINESSNAME
BUSINESS.CUSTOMSOFFICE.CUSCODE
BUSINESS.CUSTOMSOFFICE.CUSDESC
You should transform your output to explicitly and immediately include these properties.
var q_business = _context.BUSINESS.Include(b=>b.CUSTOMSOFFICE)
.Where(b => b.BUSINESSNO == int.Parse(pv_businessno)
&& b.BUSINESSSTART <= DateTime.Parse(pv_date)
&& b.BUSINESSCLOSED >= DateTime.Parse(pv_date) )
.Select(b => new {BusinessNo = b.BUSINESSNO,
BusinessName = b.BUSINESSNAME,
CustomsOfficeCode = b.CUSTOMSOFFICE.CUSCODE,
CustomsOfficeDesc = b.CUSTOMSOFFICE.CUSDESC } ) //This Select statement creates a new anonymous type that has Businessno, BusinessName, CustomsOfficeCode, and CustomsOfficeDesc properties
.FirstOrDefault();
When you bind this to your gridview, it should be able to display the value of the CUSDESC property.

Unable to search a SQL database under ASP.NET

I've added a LINQ-SQL link in my website to make objects and after that, I'm trying to write the neccesary code to search into a database.
In my case I am trying to display a column value assigned to another of other column into a DATABASE using the following code but I can't:
Palabras_Definiciones quintanaserena = new Palabras_Definiciones(); // LINQ
if (searchInput.Attributes["value"] == quintanaserena.palabra)
{
Label1.Text = quintanaserena.definición;
}
Am I doing anything wrong?

In the code above, you are not doing any request to the database. You only created the object that has the same definition as your database table.
To query your database, you need to do a query over your DataContext (usually the name of your .dbml file).
MSDN has a good web page to show sample of query. You might want to take a look there: http://code.msdn.microsoft.com/101-LINQ-Samples-3fb9811b
Your query would probably look like:
palabrasDataContext dcPalabras = new palabrasDataContext(); //palabrasDataContext would be the name of the DataContext you generated
Palabras_Definiciones quintanaserena = (from palabras in palabrasDataContext
where palabras.palabra == searchInput.Attributes["value"] //palabra is the name of the column
select palabras).FirstOrDefault(); //Using firstorDefault here if you have only one definition per word
if(quintanaserena != null) //FirstorDefault returns null if the resultset was empty
{
label1.Text = quintanaserena.definición;
}
