Accepted answer

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.
