How to filter the tree node based on the node ID in WinForms TreeViewAdv?

In the WinForms TreeViewAdv, TreeNodeAdv can be filtered based on its value by performing the iteration process. The following code example demonstrates the same.

C# Code snippet:

for(int nodeId = 0; nodeId <= 10000; nodeId++)
{
     //Custom node for ID property
    CustomTreeNodeAdv customNode = new CustomTreeNodeAdv();
    customNode.ID = nodeId;
    customNode.Text = "Node" + nodeId.ToString();
    this.treeViewAdv1.Nodes.Add(customNode);
}

//Iterates the nodes in the TreeViewAdv
foreach (CustomTreeNodeAdv item in this.treeViewAdv1.Nodes)
{
    //Gets the TextBox value
    string textvalue = item.ID.ToString();
    if(this.integerTextBox1.Text == textvalue)
    {
       //Gets the node by its ID
       MessageBox.Show(item.Text);
    }
}

VB.Net Code snippet:

' Add 10,001 custom nodes to the TreeViewAdv
For nodeId As Integer = 0 To 10000
    'Create a custom node with an ID property
    Dim customNode As New CustomTreeNodeAdv()
    customNode.ID = nodeId
    customNode.Text = "Node" & nodeId.ToString()
    Me.treeViewAdv1.Nodes.Add(customNode)
Next nodeId

'Iterates the nodes in the TreeViewAdv
For Each item As CustomTreeNodeAdv In Me.treeViewAdv1.Nodes
    'Gets the TextBox value
    Dim textvalue As String = item.ID.ToString()
    If Me.integerTextBox1.Text = textvalue Then
       'Gets the node by its ID
       MessageBox.Show(item.Text)
    End If
Next item
