i used this SQL Command to get all child and childs of child users and i dont know how can i write it with entities? <pre><code>WITH ParentUser AS ( SELECT *, 1 AS nthLevel FROM [OnlinePage].[dbo].[Users] usr1 WHERE ID = @UserID UNION ALL SELECT usr2.*, nthLevel + 1 AS nthLevel FROM ParentUser pu INNER JOIN [OnlinePage].[dbo].[Users] usr2 ON pu.ID = usr2.UserParentID ) SELECT * FROM ParentUser WHERE 1 < nthLevel </code></pre> and my users table is: <pre><code>CREATE TABLE [dbo].[Users]( [ID] [int] IDENTITY(1,1) NOT NULL, [Username] [nvarchar](50) NOT NULL, [UserParentID] [int] NOT NULL ) </code></pre> it`s something like this: <pre> |--------------------------------------| |ID |Username |UserParentID | |-----|-----------|--------------------| |1 |admin |0 | |2 |reseler1 |1 | |3 |user1 |1 | |4 |reseler2 |2 | |5 |user2 |4 | |6 |user3 |5 | |--------------------------------------| </pre> and if i want to get all childs of reseler1 with upper sql command i change @UserID with 2 and my result is: <pre> |--------------------------------------| |ID |Username |UserParentID | |-----|-----------|--------------------| |2 |reseler1 |1 | |3 |user1 |1 | |4 |reseler2 |2 | |5 |user2 |4 | |6 |user3 |5 | |--------------------------------------| </pre> now i need entity model of this sql command, i search it on google and i found something in stackoverflow(<a href="https://stackoverflow.com/questions/7753039/entity-framework-querying-child-entities">Querying child entities</a>) like down code, but not work correctly and only get one level of childs: <pre><code>var query = from m in dbSet.Where(x => x.ID == 1) join s in dbSet on m.ID equals s.UserParentID into masterSlaves from ms in masterSlaves.DefaultIfEmpty() select ms; </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
