Столбцы замораживания (блокировки) в SPGridView

Question

Я видел много примеров с замораживающими столбцами в SPGridView, но я понятия не имею, почему никто из них не работает для меня. Я имею в виду - нет замерзания.

Я буду благодарен за мой код.

Ниже приведены фрагменты кода, которые готовы к запуску. Он должен работать на IE 8+ (другие браузеры не имеют значения).

Я дам 100 баллов за решение, которое будет работать.

Answer 1

, если вы можете, используйте RadGrid для ASP.Net AJAX (Telerik). см. this link

Answer 2

Проблема, с которой вы столкнулись (на основе сайта, на котором вы ссылались) заключается в том, что «рабочая версия» в Интернете работает только в режиме Quirks, но ваша страница SharePoint 2010 даже не открывается в режиме Quirks, если вы вынуждаете это на главной странице.

Если вы можете использовать jQuery, вы можете легко создать дубликат первого столбца (если вы хотите первый столбец), я буду играть с некоторым кодом и с последующим редактированием.
