Hi,

How to refresh tree control. I have one REFRESH_TABLE_DISPLAY which is a private method. I need to refresh this tree which I have shown to the customer. How to use this method or any other alternative is available.

Thanks

Hi

There's several methods like ADD_NODE, CHANGE_ITEM, CHANGE_NODE....

Hello Naga

If you look at class <b>CL_GUI_ALV_TREE</b> it has a method <b>FRONTEND_UPDATE</b> to send changed/inserted nodes to the frontend control. This method should be called at PAI to refresh the tree display.

Hi,

You must call the method DELETE_ALL_NODES and rebuild the nodes with ADD_NODE.

And at last you must call the method frontend_update, and flush to refresh the screen.

CALL METHOD g_tree->delete_all_nodes.

LOOP...

CALL METHOD g_tree->ADD_NODE.....

ENDLOOP.

CALL METHOD g_tree->frontend_update.

CALL METHOD cl_gui_cfw=>flush.
