Как исправить все эти сообщение? Можно ли скрыть эти сообщения?

Answer 1

Это не ошибка, а информационное сообщение. Можете его игнорировать. Скорее всего, возникает из какого-то анализатора кода. Чтобы установить, добавьте DataContext = this в конструкторе формы в C# и пересоберите приложение.

Но лучше всего поизучайте, что такое привязка данных через Binding, там и узнаете про то, что такое DataContext, и с чем его едят.

Бонус

Ваша разметка, только без войны с марджинами. Разберитесь, что да как. Делать интерфейсы станет значительно проще. И да, здесь можно не фиксировать размер окна, а только задать ему MinWidth и MinHeight, размер таблицы будет меняться в зависимости от размера окна автоматически.

P.S. Не используйте Label в WPF, используйте TextBlock. Он легче и быстрее работает.
