I keep getting errors saying "master_pc is ambiguous in the namespace 'ASP' when loading some of my pages.

master_pc is the name of my main Public class in my Master Page.

The Error is on line:

Code:

Public Shadows ReadOnly Property Master() as ASP.master_pc

Could someone give me an idea of how to fix this other than renaming the class? There is no other class called this, so I'm at a loss as to why it's having a problem.

<edit>The file it references is App_Web_..... which I presume is one created by .Net during compilation</edit>

If I change the properties in the Master Page to shared then I get another ambiguous error saying "master_pc is ambiguous".

This time it relates to code in my content page that's trying to access a shared property in the master page.

Code:

master_pc.connString

Where am I going wrong?

I've only started having this problem recently...

See this: '<name>' is ambiguous in the namespace '<namespacename>'

If it doesn't work, then try renaming it.

Hmmm....I renamed it before when I had this problem. Renamed it again and it's working again.

Now I'm getting another error, "Nullable object must have a value" on one of my date fields, even though the field in the db does have a value in it and I'm using if not isdbnull(rs("dateadded")) then to populate the field......

Remove this:

Code:

if not isdbnull(rs("dateadded")) then

It's a Nullable type, so you don't have to do this check.

I tried making a change to fix the date problem and now it's saying the name of the class in my Master page is ambiguous again...

This is doing my head in!!!!!!

OK. I think I may have solved this issue, fingers crossed.

It seems that if the class of my content page was set to partial, I got the error. If I set it to Public, it stopped the error.

I had a similar issue with a user control. I removed the ClassName attribute from the Control declaration and kept the class as Partial and that seemed to solve that.

Fingers crossed this won't start happening again now...

Just a note J. On the date fields, if I have a field value as NULL and I don't have if not isdbnull() it threw an error. Damn annoying...

That's odd, because I have a property:

Code:

Private _myDate As Nullable(Of Date)
Public Property MyDate() As Nullable(Of Date)
    Get
        Return _myDate
    End Get
    Set(ByVal value As Nullable(Of Date))
        _myDate = value
    End Set
End Property

And this works when passing NULL dates.

As far as the declaration of your class...you should be able to keep it as Partial...there must be something else wrong with your code.

Must be...It's just happened again with the class set to Public.

How do I find out what the "real" problem is, because it's obviously not that the class name is ambiguous?

Maybe I'll try re-jigging things, so the shared properties I want are in my BO layer. See if that helps.
