Treenode converter examples

Here, we shall also take care that every left child of a node is smaller than the node itself and the right child is greater. This later helps in several types of search implementations. First, we define a class named TreeNode for every node in the Tree. This class will contain the value, the left , right child , and also the parent node.

Now, we must define the necessary functions to work with our Binary Search Tree. In this method, we pass a tree node and its parent node and the new value. Here, we make a recursive call to the left child. Then print the current node value and again make a recursive call with the right child. You can ignore the value i. As its sole purpose is to move to the next line after traversing the tree. In this traversal, we visit every node and print it first.

Then we make two sequential recursive calls with left and right children. We traverse the tree each level at a time.

For this one, we also need a maxHeight function to calculate the height of the Binary Tree. We shall face 3 distinct situations, the node to be deleted having —. We simply delete the required node. In case 2, for one child , we delete the connection of the node with its parent by establishing a connection between its parent and child. In the last case , for 2 children , the complexity arises. Here, we search for the maximum in the left sub-tree and update the value of the node to be deleted with it.

The tree nodes are assigned images from the ImageList that is displayed when the tree node is in a selected or unselected state. This example requires that you have a Form that contains a TreeView , and an ArrayList that contains Customer objects that each contain Order objects.

It also requires that the Customer and Order objects are defined. ImageList property. ImageKey and ImageIndex are mutually exclusive, meaning if one is set, the other is set to an invalid value and ignored.

If you set the ImageKey property, the ImageIndex property is automatically set to Alternatively, if you set the ImageIndex property, the ImageKey is automatically set to an empty string "". NET 5 and later versions: If the associated ImageList property value is changed to null , the ImageIndex property returns its default value, However, the assigned ImageIndex value is retained internally and used when another ImageList object is assigned to the ImageList property.

Count property value that is less than or equal to the value assigned to the ImageIndex property minus one to account for the collection being a zero-based index , the ImageIndex property value is adjusted to one less than the Count property value.
