Display a textbox when checkbox is checked on webform

Question

I am working in Visual Studio 2008 C# Asp.net. The Webpage is populated from the fields in the database through a databind. I am getting my information from a table in my database off of SQL Server 2005. The purpose of this Webform is for users to input information to be stored on the database. I only want to display a Textbox if the user clicks on the Checkbox. I was planning on doing this in the .CS with an IF Statement but the problem I am running into is when I double click the Checkbox and am in the Checkbox_CheckChanged method the Textbox and the Checkbox are both out of Scope. Do you have any suggestions to get the checkbox and textbox to display so I can write code behind it? Thank you!!

Try to set AutoPostBack property to true for the checkbox.

Yes when I double click on the check box it does take me to the checkbox_CheckChanged() in the .CS but neither the textbox or the Checkbox shows up with the intellisense when I try to write code in the checkbox_CheckChanged method. My textboxes and Checkbox are populated from my database through a data source connection. Why would that make the difference for me not being able to write code behind them? Thank you for your help.

How could it be out of scope? How do you got your checkBox_CheckedChanged()? If you go to your design view and double click on the checkbox it should do it for you. As long as the text box is resided in the same form you should not run into out of scope problem.
