I am populating a treeview in c# from XmlFile, and i have implemented
a multiselection in that treeview by overriding treeview select
events when ctrl or shift is pressed, which was written a seperate
DLL, and added with my project,
now i hav a problem that when i select treeview nodes by pressing
shift key at a same time initially it is creating an exception
"Object
reference not set to an instance of an object" and the application
closes.
i know this is bcoz, i have enqued selected nodes to a arraylist.
once
it presses shift its starting enqueing, and at that time selected
node
is null, thats y it is generating this exception i guess,
can anybody tell me how could i solve this?
