I want to create Binary tree in TreeView Control from List
Could not find any Logic.
My list as:
List members = getAllMembers();
I tried:
TreeView1.Node.Add(members.First());  //Root Node Add
//TreeNode LeftNode,RightNode;
Now i am getting how to move futher.

//I know the logic for Left child is: 
if (isExists( members[currentNodeIndex * 2])
 LeftNode.Nodes.Add(members[currentNodeIndex * 2]) 
//for Right child
if (isExists( members[(currentNodeIndex * 2) + 1])
 LeftNode.Nodes.Add(members[currentNodeIndex * 2])
I have record of more than 2000 members. I want to display all in hierarichal order in treeview. Could not find proper logic. Please help.

I do not have any idea on how to do this as I am having difficulty in visualizing a TreeView displaying a BinaryTree. It would end up being very, very wide for any tree with a depth greater than about 3.

However I recently bookmarked this[^] for later investigation and offer it in the hope that it might be of use to you.

Good luck! Smile | :)
