Style by hidden resource/attribute

Is there a way for me to style by a hidden resource/attribute? Every time an event is written I also log which user enters it via a insert parameter that is assigned via page_load so the user never sees this field and its not part of the form. I would assume I need to add it as a resource or attribute and then set the visibility to false and set the value to something if I want to make it work?

radTextbox doesn't hold value in service side code

I have a radtextbox that I am updating the text with JavaScript (clientside). The new value shows on the page but if I access the control server side, it shows the old value. This control is not being reloaded server side.

JavaScript: this will set the new value which shows up on the web page

document.Form1.txtTotalCharge_text.value = document.Form1.txtHdTotalCharge.value

If I access txtTotalCharge.text on the server side, the old value shows up. The asp:textbox doesn't have this issue. Can anyone tell me how to fix this.

I have a grid, and I want to export it to pdf and attach the file to an e-mail.

It seems like after calling ExportToPdf() the file is always opened. Is it possible to just save the pdf without opening it first?
