Hi,
If you check a node's checkbox, Treeviews NodeCheck event will fire. This gives you a reference to the changed Node.
This node owns a property Child wich referenzes the first child node.

Also reference the help (rightclick the treeview and select help)

The following is an untested example.

*** ActiveX-Steuerelementereignis ***
LPARAMETERS;
 toNode

local;
loNode

IF EMPTY(NODE.Children) THEN
*no Children
 RETURN
ENDIF &&EMPTY(node.Children)

*First Node
loNode         = toNode.CHILD
loNode.Checked = toNode.Checked

*.. until last Node
DO WHILE !loNode=loNode.LastSibling
*Select next child node
 loNode = loNode.NEXT
 loNode.Checked = toNode.Checked
ENDDO &&!loNode=loNode.LastSibling
