Genealogy View(family tree) in ASP.NET C# with database

In my previous post I shown how to find no of nodes in left and right of a binary tree. Now in this article I will show you how to design the binary tree in ASP.NET  C#. We had retrieve the data from database in the previous post. I remain the database structure same in this example as previous.

Database structure :

-------------------------------------------------------
Id(int) | Parent_Id (int) | Placement (NVarChar(10))
-------------------------------------------------------
1          0                        -
2          1                        Left
3          1                        Right
4          2                        Left
5          2                        Right
-------------------------------------------------------


CREATE TABLE [dbo].[tblBinaryUsers](
    [tid_no] [nvarchar](50) NULL,
    [placement] [nchar](10) NULL,
    [parent_no] [nvarchar](50) NULL,
    [First_name] [nvarchar](50) NULL,
    [enroll_time] [nvarchar](50) NULL
)  


And insert into the table 

INSERT [dbo].[tblBinaryUsers] ([tid_no], [placement], [parent_no], [First_name], [enroll_time]) VALUES (N'100001', N'', NULL, N'Arkadeep De', N'6/7/2014')

INSERT [dbo].[tblBinaryUsers] ([tid_no], [placement], [parent_no], [First_name], [enroll_time]) VALUES (N'100002', N'Left', N'100001', N'Pradeep Das', N'8/7/2014')


INSERT [dbo].[tblBinaryUsers] ([tid_no], [placement], [parent_no], [First_name], [enroll_time]) VALUES (N'100003', N'Right', N'100001', N'Mekesh Nayak', N'9/7/2014')


I added two more fields with this structure. First_Name (nvarchar(255)) and Enroll_Time  (nvarchar(20)). 

First decide how many levels you want to show in the binary tree. Then design according to that Laval. Here I have done with 4 levels. 

So design the html first and then write the coding. I also added a search facility in this project to find the ID with a DropDownList. 
 Your design will be some thing like this.

 
As the code is little bit long I am not giving these here. But don't worry here is the link where you can download the full source code.

Your output will be like this.
