How to change the TextColor of the subitems of the selected node to highlight it in WinForms TreeViewAdv?

Platform: WinForms |
Control: TreeViewAdv |
Published Date: April 30, 2011 |
Last Revised Date: February 5, 2020

Change the textcolor of subitems

This behavior can be acheived using TreeViewAdv''s MouseDown event.

C#

private void treeViewAdv1_MouseDown(object sender, MouseEventArgs e)
{
   if (e.Button == MouseButtons.Left)
      if (this.treeViewAdv1.PointToNode(new System.Drawing.Point(e.X, e.Y)) == null) 
         return;
   TreeNodeAdv node = this.treeViewAdv1.PointToNode(new System.Drawing.Point(e.X, e.Y));
   if(node.HasChildren)
   {
      foreach (TreeNodeAdv n in node.Nodes)
      {
          n.TextColor= Color.Blue;
      }
   }
}

VB

Private Sub treeViewAdv1_MouseDown(ByVal sender As Object, ByVal e As MouseEventArgs) Handles treeViewAdv1.MouseDown
   If e.Button = MouseButtons.Left Then
      If Me.treeViewAdv1.PointToNode(New System.Drawing.Point(e.X, e.Y)) Is Nothing Then
         Return
      End If
   End If
   Dim node As TreeNodeAdv = Me.treeViewAdv1.PointToNode(New System.Drawing.Point(e.X, e.Y))
   If node.HasChildren Then
      For Each n As TreeNodeAdv In node.Nodes
          n.TextColor= Color.Blue
      Next n
   End If
End Sub
