mos Posted March 3, 2021 Share Posted March 3, 2021 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?
