TreeNodeCollection::RemoveAt Method
Removes the TreeNode object at the specified index location from the TreeNodeCollection object.
Assembly: System.Web (in System.Web.dll)
Parameters
- index
- Type: System::Int32
The zero-based index location of the node to remove.
Use the RemoveAt method to remove the TreeNode object at the specified zero-based index location from a TreeNodeCollection. All items that follow that node are then moved up to fill in the vacant position. The indexes of the moved items are also updated.

|---|
The TreeNodeCollection can contain null references (Nothing in Visual Basic), as well as duplicate TreeNode objects. |
As an alternative, you can remove a specific TreeNode object by using the Remove method. You can also remove every node in the collection by using the Clear method.
The following example demonstrates how to use the RemoveAt method to programmatically remove a node from the TreeNodeCollection. Notice that the Nodes and ChildNodes properties each return a TreeNodeCollection object.
