How to Filter the Node Based on the NodeID in WinForms TreeView?

This sample describes how to filter the node based on the nodeID in WinForms TreeView (TreeViewAdv).

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

C#

for(int nodeId = 0; nodeId <= 10000; nodeId++)
{
     //Custom node for ID propety
    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);
    }
}

For nodeId As Integer = 0 To 10000
    'Custom node for ID propety
    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
