Can you pass a reference to the code-behind class into the class you are
instantiating?
c1.execute(this);
public void execute(YourPageClass cls) {
cls.Textbox1.Visible = true;
cls.Textbox2.Visible = true;
...
}
If you need to reuse these classes on different pages, then you may want
to look at creating a base page for your code behind classes to inherit
from, and then pass in a reference to your code behind class, cast as
the base page.

Subject: Re: [ADVANCED-DOTNET] Interacting with ASPX controls from a

I haven't tried this exact idea, but I think there is an explanation for
this in this article:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnvs05/
html
/migratefromaspnetto2.asp
I had a similar issue, and it was pretty tricky to work out. In our
case, we
had a set of controls in a sub-project that needed to have some shared
code.
The solution was worked out well in this post:

you in
the right direction.

Subject: [ADVANCED-DOTNET] Interacting with ASPX controls from a class
called by the code-behind class...
I have an ASPX page and I need to interact with the controls on this
page
from another class that is not my code-behind class. I cannot figure
out
how to do this without creating a property to read when the class
returns
from the code-behind class. What I would like to know is how I can
reference the controls on the ASPX page in this 2nd class but without
having
to create properties.
ASPX Page
\
Code Behind Class
\ \
Class1 Class2
The code behind class might have code that looks this...
dim c1 as new class1
dim c2 as new class2
if bl then
c1.execute()
else
c2.execute()
end if
The class code might look something like this...
Class1
public function execute()
Textbox1.Visible = True
Textbox2.Visible = True
Textbox3.Visible = False
Textbox4.Visible = False
end function
Class2
public function execute()
Textbox1.Visible = False
Textbox2.Visible = False
Textbox3.Visible = True
Textbox4.Visible = True
end function
What is unique is that I cannot easily move the functions in class1 and
class2 into the code-behind class. So I am trying to figure out if I
can do
something to give this sub-class access to the controls code-behind
class.
I know that I can modify the declarations of the controls from
"protected"
to "public" to gain access, but how to I reference them in the sub-class
if
I do this?
If I cannot do this, the only option that I can see is to merge the
code-behind class and the sub-class. I can do that, but it will be a
significantly painfully process. I am trying to avoid this if I can.
Any suggestions, ideas, samples, references, links, etc. would be very
much
appreciated. It seems like this would be a simple matter of having the
sub-class inherit the code-behind class, but I cannot see the answer or
figure out how to set up the code.
Best regards,
Jon
