Draw Unbalanced Binary Tree in ASP.NET Page

[sangam56]

Hi world.
I have some hierarchical data in which there is unbalanced binary structure.
I get the parent and its left and right child from database. I can count the total lelft and right children of any node.

But my requirement is to display first three levels in a graphical binary representation. When I click any of the leaf node, I need to get the first three levels displayed again with the exact structure of left and right children.

Who remains in left and who remains in right of a parent node is already fixed because database table stores left and right child in LeftChild and RightChild columns.

The format of data I will have from database is like this:

Parent LeftChild RightChild
100 101 102
101 103 104
102 105 NULL
103 106 107
104 108 NULL
105 109 110
106 NULL 111
107 NULL NULL
108 112 NULL
109 NULL NULL
110 NULL NULL
111 NULL NULL
112 NULL NULL

I need to do all these in asp.net 2.0. Please help me get out of this problem.
Thanks in advance.
