A TabPageAdv can be activated when holding the mouse over the tab during dragging of TreeNodeAdv using TabControlAdv''s DragOver event.


private void tabControlAdv1_DragOver(object sender, System.Windows.Forms.DragEventArgs e)


int tabIndexHit = this.tabControlAdv1.HitTestTabs(this.tabControlAdv1.PointToClient(new Point(e.X, e.Y)));

if (tabIndexHit >= 0)


this.tabControlAdv1.SelectedIndex = tabIndexHit;


this.tabControlAdv1.ActiveTabColor = Color.LightPink;



Private Sub tabControlAdv1_DragOver(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles tabControlAdv1.DragOver

Dim tabIndexHit As Integer = Me.tabControlAdv1.HitTestTabs(Me.tabControlAdv1.PointToClient(New Point(e.X, e.Y)))
