You will need to use recursion to solve this problem:

    Private Sub CallPopulateTreeView(ByVal tv As TreeView)
        PopulateEverythingUnderThisNode(tv.Nodes(0))
    End Sub
    Private Sub PopulateEverythingUnderThisNode(ByVal nd1 As TreeNode)
        For Each nd As TreeNode In nd1.Nodes
            nd.Checked = True
            PopulateEverythingUnderThisNode(nd)
        Next
    End Sub

I want the whole code .
I am working on visual studio 2008 and the framework is 3.5 .
Scenario is in a tree view there are parent nodes , children nodes at different level with check box . Now coding has to be done for these conditions
1. if u check any parent node then autoatically all children nodes get checked .
2 .if u check a particular child node then its parent node automatically gets checked .
Please give me the working code as soon as possible . It would be nice if you will give explantion too .

That is the code, my function does exactly what you asked on a treeview. It will loop through each child of a node, each child of each child, and so on and check them. You should be able to use the above code in your application which part are you having trouble with?
