Solution 2

C#

for (int a = 0; a < VisualTreeHelper.GetChildrenCount(PARENTCONTROLNAME); a++)
{
    lbl = VisualTreeHelper.GetChild(<pre lang="xml">PARENTCONTROLNAME, a) as Label;
  
    if (lbl != null)
    {
      if (lbl.Name.Equals(YOURSTRING)
      {
           // YOUR CODE TO BE PERFORMED
      }
    }
}
