are you missing a using directive or an assembly reference? RRS feed

    I cannot quite figure out why I am getting the following error.  I am using Visual Studio 2010/ .NET 4.5.

    I could not figure out an option for removing the reference and placing it back, although it does not seem to be much more than an guess...

    Error 1 The type or namespace name 'CommonPage' could not be found (are you missing a using directive or an assembly reference?) C:\Users\slyth_000\Dropbox\IS 3139 - Software Engineering\Jonathan Camilleri\bck\Aristotle\Tabs.aspx.cs 10 34 C:\...\Aristotle\

    public partial class Tabs_Tabs : CommonPage

    try by putting System.Web.UI.Page  instead of CommonPage.

    Hope this helps..

    In your code

    public partial class Tabs_Tabs : CommonPage

    It is searching for CommonPage class? I sit available in your project?

    Try type your tab control id fisrt, then property name like

    MyTab1.CurrentTab.Text = ...
