How can you have a MasterPage inherit a BasePage?

Hi,

I'm fresh to .NET 2.0 (started today) so please be patient with me! :) .

I have a masterpage and have completed the layout.
I created a BasePage and have set some variables.
I have a content (default.aspx) page and its inheriting from the BasePage.

The content page can read the variables from the BasePage.
The MasterPage cannot read the values: "CS0103: The name 'config__path_js' does not exist in the current context".

How can I get the masterpage to inherit from BasePage? I've been looking on the net and apparently you can't but there must be a way to achieve this.

In general, I want to have one file that contains variables which is fed from an XML file.
I want to be able to access these variables from Masterpage, content pages and user controls.

How can I do this?

You don't have to inherit you could make the variables static

    public static String config__path_root;
    public static String config__path_img;

 
   Then access them

    BasePage.config__path_root;

  Also the usual way to store config variables is in web.config using ConfigurationManager

  Take a look at that it offers global access to config variables.

Thanks williamcampbell for your reply. I didn't want to use the web.config because I need to use some programming logic as well when declaring the variables. This seems to work great so thanks a lot!
