Syntax

public class TreeNodeAdv : MarshalByRefObject, ICloneable, IComparable, ISupportInitialize, ISerializable, IDisposable

Remarks

The Nodes collection holds all the child TreeNodeAdv objects assigned to the current TreeNodeAdv. You can add, remove or clone a TreeNodeAdv; when doing so, all child tree nodes are added, removed or cloned. Each TreeNodeAdv can contain a collection of other TreeNodeAdv objects. This can make it difficult to determine where you are in the TreeViewAdv when iterating through the collection. To determine your location in a tree structure, use the FullPath property. The FullPath string can be parsed using the PathSeparator string value to determine where a TreeNodeAdv label begins and ends.

The TreeNodeAdv label is set by setting the Text property explicitly. The alternative is to create the tree node using one of the TreeNodeAdv constructors that has a string parameter that represents the Text property.

You can specify images for the node using the LeftImageIndices, OpenImgIndex, ClosedImgIndex, NoChildrenImgIndex and RightImageIndices properties.

The order in which the tree node's contents are drawn is as follows:

Checkbox
Option Buttons
Left images
State image
Node Label
Right images

The "State image" will be one of OpenImgIndex, ClosedImgIndex and NoChildrenImgIndex.

Selecting specific tree nodes and iterating through the Nodes collection can be achieved by using the following property values: FirstNode, LastNode, NextNode, PrevNode, NextVisibleNode, PrevVisibleNode. Assign the TreeNodeAdv object returned by one of the aforementioned properties to the SelectedNode property to select that tree node in the TreeViewAdv control.

Tree nodes can be expanded to display the next level of child tree nodes. The user can expand the tree node by pressing the plus (+) button next to the TreeNodeAdv, if one is displayed or you can expand the TreeNodeAdv by calling the Expand() method. To expand all child tree node levels in the Nodes collection, call the ExpandAll() method. You can collapse the child TreeNodeAdv level by calling the CollapseAll() method or the user can press the minus (-) button next to the TreeNodeAdv, if one is displayed. You can also alternate the TreeNode between the expanded and collapsed states using the Expanded property.

Examples

The following example displays customer information in a TreeViewAdv control. The root tree nodes display customer names, and the child tree nodes display the order numbers assigned to each customer. In this example, 1,000 customers are displayed with 15 orders each. The repainting of the TreeViewAdv is suppressed by using the BeginUpdate() and EndUpdate() methods, and a wait Cursor is displayed while the TreeViewAdv creates and paints the TreeNodeAdv objects. This example assumes you have a Customer object that can hold a collection of Order objects. It also assumes that you have created an instance of a TreeViewAdv control on a Form.

// Create a new ArrayList to hold the Customer objects.
private ArrayList customerArray = new ArrayList(); 
private void FillMyTreeView()
{
// Add customers to the ArrayList of Customer objects.
for(int x=0; x!=1000; x++)
{
customerArray.Add(new Customer("Customer" + x.ToString()));
}	
// Add orders to each Customer object in the ArrayList.
foreach(Customer customer1 in customerArray)
{
for(int y=0; y!=15; y++)
{
customer1.CustomerOrders.Add(new Order("Order" + y.ToString()));

}
}
// Display a wait cursor while the TreeNodeAdvs are being created.
Cursor.Current = new Cursor(&quot;C:\\Cursors\\MyWait.cur&quot;);
// Clear the TreeViewAdv each time the method is called.
treeViewAdv1.Nodes.Clear();
// Add a root TreeNodeAdv for each Customer object in the ArrayList.
foreach(Customer customer2 in customerArray)
{
	treeViewAdv1.Nodes.Add(new TreeNodeAdv(customer2.CustomerName));
	// Add a child treenode for each Order object in the current Customer object.
	foreach(Order order1 in customer2.CustomerOrders)
	{
		treeViewAdv1.Nodes[customerArray.IndexOf(customer2)].Nodes.Add(
			new TreeNodeAdv(customer2.CustomerName + &quot;.&quot; + order1.OrderID));
	}
}
// Reset the cursor to the default for all controls.
Cursor.Current = Cursors.Default;

}
