Trying to create stopwatches that will display in textboxes but I am getting a " does not contain a definition" error.
Hello!
What I am looking for:
When my main form loads, I want 15 stopwatches created and 15 textbox.text's to be assigned to each stopwatch. These textboxes will display the current time of each timer after it is started:
After a button click I want the corresponding stopwatch to start and the textbox.text to display the current timer. The issue I am running into is under the button clock function:
Thank you for your help with this!

Stopwatch stopwatch15 = new Stopwatch();
TimerTextBox15.Text = stopwatch15.Elapsed.ToString("hh\\:mm\\:ss");
}
After a button click I want the corresponding stopwatch to start and the textbox.text to display the current timer. The issue I am running into is under the button clock function:
public void button1_Click(object sender, EventArgs e)
{
Form1.stopwatch1.Start();
}
Thank you for your help with this!

OK. I added the Stopwatch at the class level:
And I have the textbox text set on load of Form1:
And my start button function:
The program will run, but the TimerTextBox1.text does not change?
public partial class Form1 : Form
{
Stopwatch stopwatch1 = new Stopwatch();
And I have the textbox text set on load of Form1:
public void Form1_Load(object sender, EventArgs e)
{
TimerTextBox1.Text = stopwatch1.Elapsed.ToString("hh\\:mm\\:ss");
}
And my start button function:
public void button1_Click(object sender, EventArgs e)
{
stopwatch1.Start();
}

OK. You're trying to set the textbox once only - when the form first loads.
You won't have started the stopwatch by this time, and even if you had, it won't constantly change the textbox as that only happens when you first load the form.
If you're wanting to constantly update the textbox, then you're going to need to thread the application somehow, and constantly poll the timer for updates. If you don't do this on a thread (background worker etc), then your UI will just lock.
The general approach you probably need is this:
declare the stopwatch at the class level.
start the stopwatch on form load
constantly poll the stopwatch and update the textbox from a background thread.

Thank you both, Sam and Chris, for your time and assistance!
You need to declare them at the class level (the form level in your case). Something like so;
