Using linq we can achieve the same with less code foreach ( Label l in this . Controls . OfType Label >()) if (l . Text ==0) l.Text=;

I don't think there is a way to do it except probably the following: foreach(Control ctl in this.Controls) { if(ctl is Label) { lblControl = (Label) ctl; if(lblControl.Text == 0) lblControl.Text = ''; } } The code is in C# but can easily be converted to VB.NET. Make sure to a separate method something like initControls for the purpose. Don't just write the whole code under the click of a button. However if someone has any better idea that would be nice to know.
