Hi all, I am using a tree contol in My MFC Application, It works fine, I am able to sucessfully add or delete nodes in the tree . But the problem arise when I delete all the nodes with DeleteAllItems() function . This Function deletes all the nodes, but after this I am unable to insert any new node in the tree. If I still insert a new node, tree doesn't display it, but if I click on the tree controls area where new node should have been displayed, A block of blue color appears there. I think that the new node is getting created, but there is some problem that prevents it to be displayed. Plz Give me your valuable suggestions regarding this trouble. Thank You. BBye.
