[SOLVED] How can I access programmatically created UI Elements in Xamarin.Forms : timepicker

How can I access programmatically created UI Elements in Xamarin.Forms : timepicker

I got a method which is creating UI Element programmatically. Example:

Label label1 = new Label(); 
label1.Text = "Testlabel";

TimePicker timepicker1 = new TimePicker();
timepicker1.Time = new TimeSpan(07, 00, 00);

After that I add both of them in an already existing StackLayout.

stacklayout1.Children.Add(label1);
stacklayout1.Children.Add(timepicker1);

A user of my app can create this multiple times. Now my question is, how can I access, for example, the second/ better all of TimePickers which were created?

Solution

Some suggestions:

Use ID:

var id = label1.Id;
var text = (stacklayout1.Children.Where(x => x.Id == id).FirstOrDefault() as myLabel).Text;

Use index:

Label labelOne = stacklayout1.Children[0] as Label;

Use tag:

Create a custom property tag to the label:

public class myLabel : Label{ 

    public int tag { get; set; }
}

And find label by the tag:

var labels = stacklayout1.Children.Where(x => x is myLabel).ToList();

foreach (myLabel childLabel in labels)
{
  if (childLabel.tag == 0)
  {

  }
}

BTW, if you create the label in xaml, you can use findbyname:

Label label = stacklayout1.FindByName("labelA") as Label;
