How to access a User Control from a Class

I have a user control "ItemNotes" in my application and i am trying to access this control type from a class using following code.

Control ctrl = FindControl("Note1");
if(ctrl is ItemNotes)
{
return ((ItemNotes)ctrl).Value;
}
return "";

It work fine in ASP.NET 1.1 but doesn't compile in 2.0 and i don't see control class in assigned namespace. By default, this class is in App_Code directory and is a base class for other controls.

Is there any way to handle this?

Re: How to access a User Control from a Class

A workaround is to make ItemNotes a simple class that is derived from UserControl, and then create a separate user control that derives from ItemNotes and use that in the pages.

You can add all the properties/methods that you need to the ItemNotes class (possibly making them virtual or even abstract) and then implement them as needed in the deriving user control class.

This gives you

public class ItemNotes : UserControl
{
...
}

partial class ItemNotesControl : ItemNotes
{
...
}

You should also just be able to add a Page reference to that user control
<%@Reference VirtualPath="ItemNotes.ascx" %>

Thanks DMV, I created a virtual function in the old class so now i am handling ItemNotes in derived controls. Works fine.

Re: How to access a User Control from a Class

I can add a reference to a page or another control. But i was trying to access it from a base class file derived from UserControl. This class file is in App_Code directory and working as a base class for other user controls. there were no problems in derived controls. I cannot access any page or User control in App_Code folder classes. It doesn't compile.

I found another solution as i replied to DMW.

thanks

Re: How to access a User Control from a Class

Files in App_code cannot refer classes out side. Whidbey conversion wizad solves this problem by creating an abstract base class in app_code.
This abstract base class is the base class for the classes out side App_code, and code in side app_code can still use it.

Eg:

Myppage.aspx.cs
partial class MyPage : Page
{
public int foo()
{
return 1;
}
}

After conversion

partial class Migrated_MyPage : MyPage
{
override public foo()
{
return 1;
}
}

in app_code new file generated
Stub_Mypage_aspx_cs.cs

abstarct class MyPage : Page
{
abstract public int foo() ;
}

Now code in App_code can refer MyPage and can use public methods if code has access to Migrated_MyPage instance.
