В моем UserControl есть метод, который я хотел бы вызвать при закрытии моего окна.
У меня есть DataGrid на моей странице UserControl, которая при двойном щелчке открывает новый Window и заполняет данные выбранной строки из UserControl в Textboxes в Window ,
У меня на странице UserControl есть метод, который загружает DataGrid, и я хотел бы вызвать этот метод, когда мой Window закрывается.
Ниже приведен код для загрузки моей DataGrid при загрузке моей страницы UserControl:
public void DataGridData()
{
// Attemption to connect to SQL Server database and populate DataGrid with database tables.
try
{
string connectionString = ("Data Source=WINDOWS-B1AT5HC\\SQLEXPRESS;Initial Catalog=CustomerRelations;Integrated Security=True;");
SqlConnection connection = new SqlConnection(connectionString);
// Review SQL queries for security vulnerabilities

Ниже приведен код, который я написал для обновления базы данных, когда Window закрывается. Затем пользователь возвращается на страницу UserControl, и я хотел бы от DataGrid до Load/Refresh.
