Hi!!!!!!!
I have aspx page which uses ascx(usercontrol) in it.
The ascx in turn contains a textbox and a button. if i click
the button, javascript code get executed to open another popup window,
in that code i am passing the form name , control name of the text
box. After few operations are performed in that popup window, when i
try to close the popup window, i am setting the value of the texbox in
ascx from the popup window using javascript

window.opener.document.forms[ said:
"].value = "<%= strSelectedDate %>";
Click to expand...

it's giving me the error as
window.open.document.forms["abc"].txtbox.value is null or not an
object,

From the above error, I think the reference is lost to the form.

It works fine when I am not using any ascx(usercontrol) in my aspx
page and opening directly popup window from the aspx page.

Can someone help me out in this!!!!!!!!!!!!!!!!!

thanks

Pattabi,

Have you placed form tags inside of your user control?

Asp.Net breaks if there is more than one set of form tags on a page. So you
aren't supposed to create a page, and then add a usercontrol with form tags
to it.

If indeed your user control does have form tags in it, remove them and then
just refer to the form as:

window.opener.document.Form1

You shouldn't even need to track the form name if you just stick with the
default form id that .Net assigns.
