Checkbox activates another field in a GUI???
My question is probably pretty simple for you guys (and gals)
Anyhow I am in a dreamweaver environment using asp.net and vb.net. I have built a GUI that hase several different areas for a user to input information on of the fields is a checkbox. I would like it when the user checks the checkbox it activates another field which is a textbox and requires the user to input initials to be able to submit the form. How would I go about doing this? Thanks in advance

what do you mean by activates? makes it visible or just makes it enabled to accept user input?
Making it enabled
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
If Page.IsPostBack Then
TextBox1.Enabled = CheckBox1.Checked

Sorry I did mean enables for input because it is already visible or would you suggest doing it differently?

or directly place aspx requiredfieldvalidator control like this way.
Name: <asp:TextBox id="name" runat="server" />
<asp:Button runat="server" Text="Submit" />
<asp:RequiredFieldValidator ControlToValidate="name" Text="The name field is required!" runat="server" />

All of this explains how to make a field active and require an entry. But, first you have to make sure that the Checkbox caused the postback.
