["Sai Korada" <sai korada xilinx com>]

Thanks for the suggession, and certainly by the end of this week I shall do it perfectly. Afterall its matter 
of some time to understand the depth of any new language or package....right???

You do not set the renderer "active" property anywhere
except in the toggle_cell callback.  Therefore it always
renders *all* the cells in the last state (active or
inactive) some cell was toggled to.  You need either a cell
data func or to use gtk_tree_view_column_new_with_attributes()
to tell the renderer in which state it should render the
cells.  The "active" propery is not set in any automagic
way, *something* must set it before the cell is rendered.

It seems all my previous advices were vain too.  The tree
model should have exactly two columns: G_TYPE_STRING (the
label) and G_TYPE_UINT16 (the value), and you should use
a cell data function to set renderer properties to display
the guint16 value once as toggles, once as hex, in different
columns.

In fact, everything that the code sample I sent needs to add
to do *exactly* what you want is s/64/16/g, a hex-value
column (in the view, *not* in the model) + its cell data
function + its "cell-edited" callback.  Of course, I can
write the missing bits too -- it would be shorter than this
mail -- but that would not teach you fishing.

Please read the Gtk+ Tree View Tutorial to learn the
concepts first.
