在 Stackpanel 中对动态用户控件进行排序

Question

我有一个用户控件，它有多个包含值的标签，例如上传日期、标题字符串、作者字符串等。截至目前，我正在通过为 SQL 数据库中的每一行数据创建一个新的用户控件实例来填充堆栈面板。

我想要的是单击 "Sort by Date" 按钮并让用户控件的所有实例 object 按 Stackpanel 中的上传日期排序。

我将如何处理这个？

使用用户控件的新实例填充堆栈面板背后的一些代码。

/// <summary>
/// Receive data from SQL and apply them to a new instance of itemControl
/// </summary>
public static void GetResultItems(StackPanel stackPanel)
{
    // The SQL Query
    string Query = "select * from Items";
    MySqlCommand command = new MySqlCommand(Query, connection);

    // Open connection
    connection.Open();
    MySqlDataReader reader = command.ExecuteReader();

    // While reading...
    while (reader.Read())
    {
    // Creates new instance of the itemControl
    ItemControl itemControl = new ItemControl();

    // Assign the data from the SQL database onto the itemControl labels
    //Upload Date. This contains the date for when it was Uploaded. 
    itemControl.lblListUploaded.Content = (reader["UploadDate"].ToString()); //I wish to use this value to sort by

    //Author
    itemControl.lblExpandAuthor.Content = "Author: " + (reader["Author"].ToString());

    // Add the new instance of ItemControl to the resultItem List<>
    //The list is never used, but is created incase of later usage/need.
    resultItem.Add(itemControl);

    // Add the item to the Stackpanel
    stackPanel.Children.Add(itemControl);
    }

    // Close connection
    connection.Close();
    }
}
