Windows form Treeview readonly

Hi Nainil,

BeforeCollapse() event is working. Thank you so much for your help.

Thanks for your message. I tried with putting Treeview inside the Panel. It didn't work. It disabled the treeview also. The treeview node text is disabled(faded text).

Also tried with BeforeCollapse()  but still not working.

Hi Nate,
a simple way to do what you want is to put the treeview inside a panel and set the panels Enabled property to false.

Hi Nate,

     You can handle the BeforeCollapse event of the TreeView control. The second parameter passed in is of type TreeViewCancelEventArgs. The TreeViewCancelEventArgs class contains a Cancel property which you can set to False to disallow any collapse of nodes. Hence the code snippet should be as follows:

private void treeView1_BeforeCollapse(object sender, TreeViewCancelEventArgs e)

{

e.Cancel = true;

}

Doing above should never allow the user to collapse a node.
