     </ContentTemplate> 
    </asp:UpdatePanel> 
</div> 

Требование в том, что на основе выбора ниспадающего, я хочу, чтобы изменить позиции TableRow из таблицы tbl_Approvals.

Как достичь этого, поскольку я не могу использовать <div> внутри <asp:Table>.

Answer 1

Если бы это было мне, я бы создать различные стили я хотел бы как классы CSS тогда, когда изменения индекса для вашего выпадающего списка изменить атрибут класса для таблицы (или строки, которые когда-либо имеет смысл) с помощью:

[object id].Attributes.Add("style", "someCssClass;");
