Hi
I have a question about this control
I have a lot of info in this control like 60k listed some are nodes some are leaf
On this TreeView control have checkbox
I want to check a node and all of the leaf and nodes inside of the principal node change the false checkbox to a true checkbox
I try it to do it (I finally did it) but what I do it's expand all of the nodes in total to have the really subscript of the files and then change the state of the checkbox
this works fine if I have like 20 or under 100 info on the treeview but when I have like 60k list on the treeview it's when it gets really bad
someone know how to control this more fast?
I know that my method it's really bad but it was the first solution I get
I don't find any way to have a node and then change all inside that node
Please help!
