First, you need to have some class to store your category collection in tree.

For example:

public class CategoryBO
{
 public int CategoryID{get;set;}
 public List<CategoryBO> SubCategories{get;set;}
}

or

public class CategoryBO
{
 public int CategoryID{get;set;}
 public int? ParentCategoryID{get;set;}
}

Then you should implement some method to bind checkboxlist or treeview (with checkboxes) into some control in which you will save required information about category (f.e. with ParentCategoryID to identify parent).

One of the way if you are using CheckBoxLists is to store path in Value in every ListItem and then read this information to identify parents.
It looks like this^

<asp:checkboxlist id="Parents" runat="server" >
<asp:listitem text="Employees" value="1">
<asp:listitem text="Unemployees" value="2">

        
<asp:checkboxlist id="Childs" runat="server" >
<asp:listitem text="Company1 Employees" value="1/1">  
<asp:listitem text="Company2 Employees" value="1/2">

        
<asp:checkboxlist id="Company1Employees" runat="server" >
<asp:listitem text="Peter" value="1/1/1">
<asp:listitem text="Pavel" value="1/1/2">
