Hi aspvijay04,

I am assuming you don't want TreeView node to be selectable.

You can do with BeforeSelect event and you can cancel it.

For using TreeView in Windows Application refer below article.

Populate TreeView from Database in Windows Forms using C# and VB.Net

C#

private void treeView1_BeforeSelect(object sender, TreeViewCancelEventArgs e)
{
    e.Cancel = true;
}

VB.Net

Private Sub treeView1_BeforeSelect(sender As System.Object, e As System.Windows.Forms.TreeViewCancelEventArgs) Handles treeView1.BeforeSelect
    e.Cancel = True
End Sub
