selecting many nodes at the same time in a treeview

Question

Hi,

You can select a node in a TreeView by:

treeView1.SelectedNode....

Is it possible to select many nodes at the same time?

i have a treeview and a button when you select a node and click on the button it saves selected nodes name ,
now i want to select many nodes at the same time and when i click on the button it saves all nodes.

thanks.
