asp:label control doesn't show up as a form element

[John Holmes]

I would like to turn on a label control in javascript with the onfocus event
of another control by setting the Visible property to true. When I try and
reference this label control it says "Microsoft JScript runtime error:
'document.Form1.lblSigGrantor' is null or not an object". I wrote a loop and
iterated through the elements for the form and this control doesn't show up.
Code listed below, please help.

Thanks,

John Holmes

John,

Labels are not form elements, they are more directly document elements.
They convert to SPAN tags in HTML code, which are not attributues of a form
object. Lose the Form1. document.lblSigGrantor.Visible

HTH,

When a control's Visible property is set to False on the server, the HTML
for that control is not sent down at all. Since it isn't sent down - there
is no way to make it visible, since it doesn't exist.

You would have to do something like:
myLabel.Attributes.Add("style","visibility=hidden")
on the server, to set the visibility to hidden. Then, in javascript, you
would set it back to visible or whatever it is.
