Handling parent & child behaviour using tree view

["Saba Khan" <s_i_uk hotmail com>]

Hello,
Sorry for my last thread as now requirement is little bit changed now. 
Parent child behaviour in tree view when i select the child toggle button , 
All parents are selected by default itself if it does not
selected already.
And now when i use to select parent toggle button parent should be selected 
in that way as well as its childs also.
So how i can make this relation using tree view.
I used this method, gtk_tree_model_iter_parent() but i have problem like 
this.
gtk_tree_store_iter_parent: assertion `child->stamp == GTK_TREE_STORE 
(tree_model)->stamp' failed.
(:7868): Gtk-CRITICAL **: gtk_tree_store_set: assertion `VALID_ITER (iter, 
tree_store)' failed

Please do me feedback.
