asp.net building controls:

Hi All,

I'm building an Webcontrol and overriding OnPreRender i want inject
client javascript, but RegisterStartupScript and
IsStartupScriptRegistered is not been shown in the list of methods of
Page object.

If i put Page.IsStartupScriptRegistered or Page.RegisterStartupScript
in code i don't get an Compile-Time error, but a Runtime error occurs:
NullReferenceException

Thanks in advance

My guess is you are not adding this web control to the page properly
when testing it. Do you declare this control in an aspx or ascx page?
Or do you use this.Controls.Add(mycontrol) somewhere? You must do
one or the other for Page to be not null during PreRender.

Hi,

If you use VB.NET it's known issue. you wont see those methods with
intellisense but you can use them (you wont get any compile error).
