I have a query about arraylist.
i have some child nodes in a treecontrol. when i select a node and click a button the tree node gets added in richtextbox. similarly i select few more nodes and add them in richtextbox. till here i did it. Everytime i add a node into richtextbox, the node must be captured by a arraylist. i.e. for ex if i add node1,node2,node3 to richtext box, i want these nodes in a arraylist with a delimiter "," (comma) and this arraylist must be saved in db.
So how to create an arraylist How to add nodes in it with a delimiter comma during the button click event.How to save the arraylist in DB
Please Help me,
