I want to loop through controls nested in a grid in wpf

I have this grid with button and labels :

"95" VerticalAlignment="Top"
Background="{StaticResource TopBar}">
"{StaticResource MyButtonStyle}" Content="" HorizontalAlignment="Left" Margin="1208,8.04,0,0" VerticalAlignment="Top" Width="185" Height="77" ToolTip="Main Catalogue " Cursor="Hand" Click="Button_Click"/>
"40" HorizontalAlignment="Left" Margin="20,20,0,0" VerticalAlignment="Top" Width="200" TextWrapping="Wrap" FontSize="21.333">"en-gb" Text="Promotions"/>
"{StaticResource MyButtonStyle}" Content="" HorizontalAlignment="Left" Margin="304,8,0,0" VerticalAlignment="Top" Width="185" Height="77" ToolTip="Main Catalogue " Cursor="Hand" Click="Button_Click">
"/Images/LibraryCatalog.png"/>

in code behind i managed to use the following method found online to find one instance of a button then locate the label for that button for the purpose of changing the language in a resource file accordingly

public static T FindChild(DependencyObject parent, string childName)
where T : DependencyObject
{
// Confirm parent and childName are valid.
if (parent == null) return null;
T foundChild = null;
int childrenCount = VisualTreeHelper.GetChildrenCount(parent);
for (int i = 0; i < childrenCount; i++)
{
var child = VisualTreeHelper.GetChild(parent, i);
// If the child is not of the request child type child
T childType = child as T;
if (childType == null)
{
// recursively drill down the tree
foundChild = FindChild(child, childName);
// If the child is found, break so we do not overwrite the found child.
if (foundChild != null) break;
}
else if (!string.IsNullOrEmpty(childName))
{
var frameworkElement = child as FrameworkElement;
// If the child's name is set for search
if (frameworkElement != null && frameworkElement.Name == childName)
{
// if the child's name is of the request name
foundChild = (T)child;
break;
}
}
else
{
// child element found.
foundChild = (T)child;
break;
}
}
return foundChild;
}

then use it in code behind as follow:

private void Set_Language()
{
Label lblText = UIHelper.FindChild(Application.Current.MainWindow, "lblWebLinks");
strLanguage = "LibraryAccess.Languages." + ((ComboBoxItem)ddlLanguage.SelectedItem).Name.ToString();
ResourceManager LocRM = new ResourceManager(strLanguage, typeof(MainMenu).Assembly);
if (lblText != null)
{
lblText.Content = LocRM.GetString("lblWebLinks");
}
}

My question is the method above it could only locate one label by name, is there any way i could loop trough each one of the label on the above grid for each button then use the set_language method to loop then use something like: foreach label in grid x.

please advise

You can do this like
foreach (UIElement ele in GridName.Children)
{
if (ele.GetType() == typeof(Label))
{
Label lbl = (Label)ele;
//Do the Work on label like below mentioned
lbl.Margin = new Thickness(e.HorizontalOffset, 0, 0, 0);
}
}
