E.g. you have a method like this:

private async void EditComboBox_SelectionChanged(object sender, SelectionChangedEventArgs e)
{

You can detect which object (ComboBox in this example) triggered it with this:

	var PageObject = sender as ComboBox;

	if (PageObject.Name == "MyObjectName")
	{

	}

If you use names that include an ID value, say:

	var PageObject = sender as ComboBox;

	if (PageObject.Name.Contains("MyObjectName"))
	{
		string sThisObjectId = PageObject.Name.Substring(12);            //Convert "MyObjectName14" to "14"

	}
