I have finally managed to get a Popup Window to appear and close. My problem is that when I "save" the data entered in the popup, I cannot get the parent form to reload the page and show the textbox values.
Please forgive the sloppy code and all the comments. I have read dozens of examples.
I get error "Unable to get property of 'document' of undefined or null reference" and VS2017 shows this:
I am a newbie to javascript. I think it might be related to the fact that when I am typing in a <script> block, after I type 'window', several properties pop up. When I add '.opener' I see more properties, but neither 'document' nor 'location' are
listed. It is like I am missing a reference?
Thanks in advance for all the help I know I will get.

According to your description, you want to open parent form from popup, but get that error message.
if you want to operate the current window, you could use window.opener or window.document directly in script tag, for more details, please check the following tutorial:

I finally got the parent page to do a PostBack! I read so many examples and heeded the advice of those that tried to help. None of that worked. Then I stumbled on the solution.
I did not understand that the Page_Load event happens BEFORE the button Click event. DOH!
I found a post that led he here:
' Do a Postback to Display Unit and Price
Protected Sub bSavePrices_Click(sender As Object, e As EventArgs) Handles bSavePrices.Click '
tUnit = eUnit1.text
tRegPrice = ePrice1.text
Dim sb As System.Text.StringBuilder = New System.Text.StringBuilder()
sb.Append("<script language='javascript'>")
sb.Append("__doPostBack('','');")
sb.Append("</script>")

Missing Something Fundamental About Javascript and Popup Windows

Hi mmieher,
According to your description, you want to open parent form from popup, but get that error message.
if you want to operate the current window, you could use window.opener or window.document directly in script tag, for more details, please check the following tutorial:
https://developer.mozilla.org/en-US/docs/Web/API/Window
In your case, you want to operate parent form from popup, please check the following tutorials:

I finally got the parent page to do a PostBack! I read so many examples and heeded the advice of those that tried to help. None of that worked. Then I stumbled on the solution.
I did not understand that the Page_Load event happens BEFORE the button Click event. DOH!
I found a post that led he here:
' Do a Postback to Display Unit and Price
Protected Sub bSavePrices_Click(sender As Object, e As EventArgs) Handles bSavePrices.Click '
tUnit = eUnit1.text
tRegPrice = ePrice1.text
Dim sb As System.Text.StringBuilder = New System.Text.StringBuilder()
sb.Append("<script language='javascript'>")
sb.Append("__doPostBack('','');")
sb.Append("</script>")
ScriptManager.RegisterStartupScript(Me.Page, Me.GetType(), "JSCR", sb.ToString(), False)
end sub
There is NOTHING special in the aspx file other than the bSavePrices button.
Hope this helps somebody else.
Marc
