inheritance problem

[wawalter]

Hello,

I am trying to have my web page inherit from another page in .Net 2.0. It usually works fine, but every once in a while some or all of the child pages return this error:

The type or namespace name 'NETBasePage' could not be found
(are you missing a using directive or an assembly reference?)

If I check everything back into Source Safe and check it out again it will work fine for a while and then I will start getting the error again.

This is what my code looks like:

public partial class MailerEditNET_ProdCat : NETBasePage

and here is the base class:

public partial class NETBasePage : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }

    #region Deserialize the Mailer class
    protected Mailer DeserializeMailer()
    {
        HtmlInputHidden hid = new HtmlInputHidden();

        Page callingpage = (Page)Context.Handler;
        hid = (HtmlInputHidden)callingpage.FindControl("hdnMailer");
        string mailer = hid.Value;

        if (mailer.Length > 0)
        {
            byte[] normalisedForm;
            normalisedForm = Convert.FromBase64String(mailer);

            if (normalisedForm.Length > 0)
            {
                BinaryFormatter serializer = new BinaryFormatter();
                MemoryStream ms = new MemoryStream(normalisedForm);
                return (Mailer)serializer.Deserialize(ms);
            }
        }

        return null;
    }
    #endregion

    #region Serialize the Mailer class
    protected string SerializeMailer(Mailer mailer)
    {
        IFormatter formatter = new BinaryFormatter();
        MemoryStream str = new MemoryStream();
        formatter.Serialize(str, mailer);
        string formSafe = Convert.ToBase64String(str.ToArray());

        return formSafe;
    }
    #endregion

    #region Check to see if Mailer class has been serialized
    protected bool CheckSerialization()
    {
        HtmlInputHidden hid = new HtmlInputHidden();

        Page callingpage = (Page)Context.Handler;
        hid = (HtmlInputHidden)callingpage.FindControl("hdnMailer");
        string mailer = hid.Value;

        if (mailer.Length > 0)
            return true;
        else
            return false;

    }
    #endregion

Thanks for any help,
Bill

Could what you are trying to achieve not be done with Master Pages rather than Inheritance as that would seem a more logical method?

In case anyone is having a similar problem, I think I found the solution.

I added

<%@ Reference Page="NETBasePage.aspx" %>

to the top of all my .aspx pages that inherit from NETBasePage.

Since I did that all the current errors, that I previously fixed by checking in and out of source safe, went away and I haven't had any new errors.
