textbox visible property

[Pato2705]

I would like to pass a hidden textbox value through my form. The problem is that when the asp:textbox is not visible the value is null and when it is visible the value is populated. How can I populate the value and still keep the textbox hidden<BR><BR>Thank you<BR>Have you considered using the View State to do this?<BR><BR>You can read about it in the QuickStart docs under "Maintaining Application State"<BR><BR>It says this about them - "Store small amounts of request-specific data in the view state. The data is sent from the server to the client and back"
