>I am using a treeview and i want to display the nodes that apply to a certain criteria( ex:only the employees who are programmers out of the total etc). Can anybody help?

So you already have the treeview populated with nodes, where the nodes show the relationships between your tables? Do you mean populate the treeview with new nodes pertaining to the criteria you want, or "hiding" existing nodes to display only those nodes that fit your criteria?

Note that you cannot "hide" a node, if that's what you want. You must delete it (or collapse it if it's within a tree) to hide it.
