how to call supply function?

[former_member720137]

Hi All

I have a requirement that once i click on ' save ' button data should be saved and values inside a table should also be refreshed. i have used supply function to populate the data in the table. Just want to know is there any way that i can call supply function from a normal method?

Regards,

Hi,

using Invalidate method you can refresh your data's.

The sample code is,

data : node_node1 type ref to if_wd_context_node.

node_node1 = wd_context->get_child_node( name = 'NODE1' ).

 elem_node1 = node_node1->get_element( ).

node_node1->invalidate( ).

Thanks.

Hi,

You can use the "Expanded" property in the tree. If you set this as "X" menas it will expand your tree.

Thanks.

Hi Viji

Actually all i want is that in whichever state that tree is, its state should not change only data should change in the tree.. is it possible?

hi puneet...

you can call your supply function by invalidating the node like,

<node>->invalidate().
