problem in posting info frm child form to parent

aravwind · July 27th, 2004, 01:06 AM

web application
ASP.NET & VB.NET(code behind)

i got a parent form "parent.aspx"
have placed a button "Attachment" and a div "div1"
"onclick" i open the form "fload.aspx"
i got a "file control" and a list box.
the buttons are "add", "remove", and "attach"
i store the list of files in a hidden variable "txthd2".
when onclick "attach", i assign the values in the "txthd2" to the div
of the parent.aspx and close the fload.aspx window.
when i click the attach button in the fload.aspx file it is saying an error
line: 1
char: 48
error: Expected ';'
url: http://localhost/lf/fload.aspx

the code used for attach button is

Private Sub btnAt_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAt.Click
        Dim i
        Dim arr As Array
        For i = 0 To ListBox1.Items.Count - 1
            arr = Split(ListBox1.Items(i).Value, "\")
            txthd2.Value = txthd2.Value & arr(arr.Length - 1) & ","
        Next

        Response.Write("<script language='javascript'>")
        Response.Write("function attach()")
        Response.Write("{")
        Response.Write("If (Form2.txthd2.value != '')")
        Response.Write("{")
        Response.Write("var parentFrm = window.parent.document.forms[0];")
        Response.Write("parentFrm.div1.innerHTML = Form2.txthd2.value;")
        Response.Write("window.close();")
        Response.Write("}")
        Response.Write("}")
        Response.Write("attach();")
        Response.Write("</script>")
    End Sub

i don't know why the error is coming

First off: Thank you for provided the basic information about the application you are working on. (Obviously you read the forum description.)

I see a problem with your javascript:
"If" should by "if" (little i)

ur saying is right
also i wore in the onclick event of the "btn_attach"
both client side script and serverside script.
as the clientside script is called first, there will be no
data stored in thwe hidden variable
so it was not functioning
now i changed the entire "btn_attach" click event to client side
it is working fine
and here is the code:

thank you

don't laugh at me planoe. i don't know to write in a single script so i written a part of script in vbscript and the rest in javascript and
called the vbscript in java script and put it in the <head> section. the problem is solved now.

<script language="vbscript">
public Function aa()
Dim i
Dim arr

For i = 0 To Form2.ListBox1.length - 1
   arr = Split(Form2.ListBox1.options(i).Value, "\")
Form2.txthd2.Value = Form2.txthd2.Value & arr(ubound(arr)) & ","
Next

Form2.txthd2.Value = Left(Form2.txthd2.Value,len(Form2.txthd2.Value) - 1)
End Function
</script>

<script language='javascript'>

</script>
