navigation and etc.

i use of Page.LoadControl method on these user controls but i get this error
: "object reference not set to an instacne ..."

I can see what you are trying to do

According to msdn help, the 'LoadControl' method takes (string virtualPath) as the arguement. And the 'virtualPath' specified the 'virtual path to a user control file

That means you cannot load 'custom control' that way

You can try doing something like this (in your user controls)
MyCustomControl mcc = new MyCustomControl()

You can also consider using Rendered Custom Controls, which you can programmatically stream out html.

Interesting fact...
LoadControl worked well for me
(Page.LoadControl("~/subfolders/UserControl.ascx"),
but when I tried programmatically add it like this
dim ucMyUserControl as UserControl
ucMyUserControl = new UserControl
I got "reference to null" error...
How come?
So what's the way to create/load UC dynamically according to language
reference? Thanks.
