How to define value of under parent in the table
<p>In the some sample like "Binding of Hierarchy Data Structure to Tree view Control
(http://www.codeproject.com/Articles/140827/Dynamic-Binding-Of-Hierarchy-Data-Structure-To-Tre)
there is one table " tbl_Tree_Hierarchy" , in this table there is one column it's name is "under_parent" for the root its value is "0" but for some others I do not know how it's value has been defined.
I can understand level depth but under_parent for me is difficult. please help how we have to define value for that.</p>

<p>Best Regards.</p>
