Web control in web control
Hi,There are two simple web user controls A and B, where B contains A. They just display the bunch of text boxes, so I do not need them even in tool pane. They sit in the same project next to web form.I noticed that web user control put on ASPX page does not appear in code behind, but if I create it with protected keyword and name being exactly the same as id it works fine. I can access such a web control from code behind and see the value assigned in IE. The problem is that the same routine does work for my A web control in B. When I assign the value IE, I keep getting null reference. ...Controlling web control instances on Web Form

I only want one instance of the control on the Web Form. What setting in my project to I adjust to enable this functionality? I can not find it in any of the books that I have referenced. Is this a setting or is this code that has to be added to the inheriting class.
Looks like there is no standard apporach. But I'd consider using static field to count number of created objects and throw exception if second object ...Filling a textbox on a parent web user control from a child web form

I want than forward the ID to the web user control so that a grid view can load data from a database for that ID.

I am trying to pass values from one web form to another web form. I know that there are 3 ways of doing this: queryString, Server.Transfer and Session. I am using the Server.Transfer method. But I am not able to create, in my 2nd web form, an instance of my 1st web form. My 1st Web form is named CallTrack.aspx and my 2nd is named Export.aspx.
What I mean is something like this: Public value as CallTrack. I can't create it in my 2nd web form because when the intellisense is displayed, there's no CallTrack in the options.

What would you suggest me to do to?
Thanks in advance.
