BCALV_TREE_SIMPLE_DEMO - Event when clicked on Header Node?

Hi Experts,

In the program BCALV_TREE_SIMPLE_DEMO, I am looking for Method when collapsed the 'HEADER' node.

When collapsed the CHILD NODE, CL_GUI_ALV_TREE_SIMPLE->HANDLE_EXPAND_NC method is triggered.

I looked in same class for method which triggers when clicked/collapsed on HEADER Node. Please share if any ideas.

Screen shot as below for reference.

    Hi Rafi,

    all structure nodes are behaving in the same way. The difference is that when the initially visible part of the tree was created the flights were not added to the tree structure. That means the Nodes on Level 2 do not have children so method handle_expand_nc gets triggered. If you collapse the node again and re-opens it method handle_expanded_nc does not get triggered again.

    I fear what you want to do is not possible.
