2 mins read

Create custom property

In the WinForms TreeView, you can add custom properties by creating custom TreeNodeAdv class that is inherited from the TreeNodAdv. The following code example demonstrates the same.


//Creates custom TreeNode class.
public class CustomTreeNodeAdv : TreeNodeAdv
    public CustomTreeNodeAdv()
        // Initializes according to the need.
    private int m_NodeId;
    /// <summary>
    /// Gets/Sets the ID in the TreeNodeAdv.
    /// </summary>
    public int ID
        get { return m_NodeId; }
        set { m_NodeId = value; }
for (int i = 0; i < 100; i++)
    CustomTreeNodeAdv node = new CustomTreeNodeAdv();
    node.ID = i;
    node.Text = "Node" + i.ToString();
//Displays the Node ID.
MessageBox.Show("ID: " + (this.treeViewAdv1.SelectedNode as CustomTreeNodeAdv).ID.ToString());



'Creates custom TreeNode class.
Public Class CustomTreeNodeAdv
    Inherits TreeNodeAdv
    Public Sub New()
        'Initializes according to the need.
    End Sub
    Private m_NodeId As Integer
    ''' <summary>
    ''' Gets/Sets the ID in the TreeNodeAdv.
    ''' </summary>
    Public Property ID() As Integer
  Return m_NodeId
        End Get
        Set(ByVal value As Integer)
  m_NodeId = value
        End Set
    End Property
End Class
For i As Integer = 0 To 99
    Dim node As New CustomTreeNodeAdv()
    node.ID = i
    node.Text = "Node" & i.ToString()
Next i
' Displays the Node ID.
MessageBox.Show("ID: " & (TryCast(Me.treeViewAdv1.SelectedNode, CustomTreeNodeAdv)).ID.ToString())
