Finding and manipulating a UI control with a particular Name

OK so I have to work with lots of toggle button and textbox, so I named them in such way that adding letter "Q" to button's name will give name of the textbox that the button corresponds to. I have link all the button to the same method on checked event, and using this naming mechanism I, hope to manipulate the textbox corresponding the button.

What I have done till now is, generate an name of the textbox in string format. But i don't know to how to use this string to manipulate the textbox.

private void OnbuttonClick(object sender, RoutedEventArgs e)
{
        ToggleButton tb = (ToggleButton)sender;
        if(tb.IsChecked==true)
        {
            string tbnam = ((ToggleButton)sender).Name;
            string name2 = tbnam + "Q";

            ?????? (what happens from this point onward)
        }
    }

"name2" is the name of textbox that corresponds to the toggle button of name "tbnam".

I hope the I have made the problem clear.

In WPF, a much better way to do this would to expose a collection of objects in the viewmodel, and display in the UI with an ItemsControl with an ItemTemplate that would dynamically create as many iterations of ToggleButton/TextBox pairs as needed. I'd be happy to go into how to do that, if you're interested.

But for now, you can get your code working using the FindName(string) method:

private void Button_Click(object sender, RoutedEventArgs e)
{
    ToggleButton tb = (ToggleButton)sender;
    if (tb.IsChecked == true)
    {
        string name2 = tb.Name + "Q";

        TextBox tbox = FindName(name2) as TextBox;

        //  Check to see if tbox is null, do stuff with it
    }
}
