Works fine when manually clicking the button. I have in codebehind added onload attribute to the body tag of my IFrame, that calls this method in certain situations, but this doesn't work.

Any suggestions why..??

I think it should help if you introduce some intermediate non-abstract class before your generic control. Tools may try to instantiate base class without your control builder.

It works for simple custom controls.

If your generic control inherit from an abstract class, it doesn't work... for example, if it's inherit from BaseDataBoundControl class, an exception is thrown...

Somebody know how to pass through this ?

It does work under 3.5 as well (note that 3.5 uses the same System.Web). The trick, in my case, was that 3.5 has better support for nested master pages: if you have a nested master, make sure to iterrate all the way to the root before you can access child controls on PreInit (e.g. this.Master.Master).

Also finding that this does not work in .NET 3.5. However, one thing I've noticed is that if you type this.Master in the Immediate window of the IDE, it does have the desired effect. I guess the IDE invocation does a deeper prodding of the object.

Unfortunately, this trick doesn't seem to work if the control you are trying to access is also inside an UpdatePanel. Any suggestions?

Thank you for answer. You are right in .NET 3.5 your solution works. The reason of my problem was that for master of the page I use nested master. And then I add line MasterPage master = this.Master I get the same error: Exception Details: System.NullReferenceException: Object reference not set to an instance of an object. But then I add line MasterPage master = this.Master.Master, all work. Thank you very much for help.
