How can I pass variable or Property values from my popup webForm to the
webform that opened this popup?
For information that's in a control (i.e. Textbox), I'm using javascript and
document.getElementById:

var variable = document.getElementById('txtBox).value;

But if the control is hidden, that javascript code generates an error. Can
this be done with properties?
Thanks.

I'm assuming that the missing apostrophe after txtBox is just a typo...?

Sigh - WHAT ERROR DOES IT GENERATE?

Yes.

there is hidden (type=hidden) and invisible. javascript can see hidden
fields. fields marked invisible are not render, so the brwser does not see
them.

Thanks for the post. Sorry about the vague post.
The missing apostrophe was just a typo when I posted the message.
The error I get when I try to get the server-side textBox value (when
visible= false) is "Object Requred". If I make it visible, it works. The
problem is that this information doesn't need to be displayed.
I'm using server-side textboxes because they interact with a gridview and I
feel more comfortable with them. So I can't use (Type= hidden).
How can this be done with properties instead of retrieving the value of the
Textbox?
Thanks.

Try this.

<asp:TextBox style="display:none" runat="server"
ID="txtTest"></asp:TextBox>

It will still render and your javascript will work as expected.

Yes, I agree with Gozirra.

Some more information: for server-side textboxes, if you set the
Visible property = false, then asp.net tries to be "smart" and does not
render the text box at all. This is not what you want and is
completely different from rendering a textbox that is not visible.

Three common ways to solve your issue:
1) CSS Solution: Like Gozirra said, use the display:none style
2) Asp.Net 1.1 Solution: In the code-behind, use
"Attributes.Add(visible, false)". This will set the html visible
property to false, not the ASP.Net Visible property.
3) Asp.Net 2.0 Solution: Asp.net 2.0 has a new control to solve this
issue called: <asp:hiddenfield>. This is probably the preferred way
to do it in asp.net 2.0. Microsoft created the hiddenfield control to
solve the problem you are having. Use a HiddenField control instead of
a TextBox.
