Determining the type of a UserControl (ascx) in code

[Trevor Andrew]

Hi There,

I have a usercontrol that presents the majority of a page's content. Within
the ASP.NET application it appears as XXXX.PageContro l, where XXXX is the
namespace of my project. There will only ever be one and onely one of these
controls per page. I want to identify the control and set a particular
property depending upon what the current page is.

I want to find this control generically, so I wrote the following code:

for each ctl as control in me.controls
if ctl.GetType is GetType(PageCon trol) Then
....
exit for
end if
next

But this is never true. If I examine what is returned by
ctl.GetType.ToS tring, I see "ASP.PageContro l_ascx".

Any advice on how to get this comparison working would be appreciated!

Cheers,
Trevor

That is because ASP.NET actually inherits from the class that you create
(that is what appears on your page, not what you create). You will have to
check for the type that is actually created when the code is compiled.

You might try using something like the "is" operator. I believe this takes
into account inheritance, so "if( ctl is typeof(PageCont rol)" this might
return true of any class that derives from PageControl.

Hi Peter,

Thanks for your reply. Your suggestion worked. The expression "Typeof (ctl)
is PageControl" returned true when expected.
