Hi, In the Delphi VCL the TTreeView has an OnChanging event handler which allows you to check what the current node is, the node about to be selected and if the change will be allowed. Is it possible to implement something similar as I need to know what the current node is and then allow or disallow the node change based on some criteria?

At runtime I am setting the selected node however this node maybe not be in the visible area of the treeview as the treeview may contains a lot of items. How can I scroll the treeview so the selected node is visible?
