Hello Gaurav,
you have to set selection mode of table context in do_init_context method of table view controller.
Do init context code:
me->typed_context->ztablecontext->set_selection_mode(
iv_selection_mode = cl_bsp_wd_context_node_tv=>selmode_multi ).
and,
.html code:-
<chtmlb:configTable ... selectionMode = "<%= ztablecontext->selection_mode %>" ... />
Thanks,
Amit
