I would like to create a class that changes some basic
attributes of a web page based on values in a database.
Things like background color, font, text color, etc. My
problem is that I'm not sure how to pass the
variable 'this' to a class function. I need to be able
modify the properties of the controls on the web page.
Has anyone done something like this?
Thanks for the help!

I believe your problem lies in the fact that your function defines the
parameter type as a reference to the Base Page class, rather than a
reference to your inherited Page class. The types don't match exactly.

news:02****************************@phx.gbl... Kevin,
Thanks for the reply.
I'm receiving the following error...
C:\inetpub\wwwroot\MYOWorks\schedule.aspx.cs(114): The
best overloaded method match
for 'MYOWorks.MYOPage.SetPageDefaults(ref
System.Web.UI.Page)' has some invalid arguments
I didn't mention in my first post I'm using C#. I'm not
sure if this makes a difference in the coding example.
Here is the code I'm using...
In the class...
public void SetPageDefaults(ref System.Web.UI.Page
objPage)
{
.
.
.
In the program...
pageSetup.SetPageDefaults( ref this );
Thanks,
Gary

In your class:
private function doWithThis(ref System.Web.UI.Page
objPage){
// do something with the Page
}
In your page:
ClassName.doWithThis(ref this);

make changes to the data contained therein, but not the reference itself.
In her case, it really wouldn't make any difference, since she only wants to
make changes to the properties of the page.

objPage already a reference?
