Passing querystring to iframe

darkgen · 18 Oct 2019 at 12:00

I thought this would be dead easy but no..... I need to embed a page inside another and pass the query string to it from the parent to the embedded page..

Querystring

Code:

?Tick_ID=ABC12345

Code:

<iframe id="MyIFrame" src="https://website.domain.com/info.asp?ticket_id=<%Tick_ID%>" runat="server" scrolling="auto" width="100%" height="768px" frameborder="0"></iframe>

I don't believe I need any code behind it but clearly I'm missing something as the string is not passed.

TIA!

Try removing runat="server"

ah.

Code:

Compiler Error Message: BC30451: 'Tick_ID' is not declared. It may be inaccessible due to its protection level.

Clearly I'm erm defining Tick_ID in the right place?

Code:

Parser Error Message: Server tags cannot contain <% ... %> constructs.

Hmmm, strange error. I'll continue to play ...

Replacing " with '

Code:

<iframe id="MyIFrame" src="https://website.domain.com/info.asp?ticket_id=<%=Request.QueryString['Tick_ID']%>" runat="server" scrolling="auto" width="100%" height="768px" frameborder="0"></iframe>

Renders the page but again not passing the querystring.

Take runat server off.

Then generates the following error.

Code:

 Compiler Error Message: BC30203: Identifier expected.

So to be clear, for my understanding. I have a selection gridview on one page which directs to another page on the same site with a querystring.

Code:

https://firstwebsite.domain.com/somepage?tick_id=ABC1234

Within somepage on the first site that which contains iframe to another source address where I wish to pass the querystring from the first.

Code:

<iframe id="MyIFrame" src="https://secondwebsite.domain.com/anotherpage?ticket_id=<%=Request.QueryString["tick_id"]%>" runat="server" scrolling="auto" width="100%" height="768px" frameborder="0"></iframe>

This should iframe to

Code:

https://secondwebsite.domain.com/anotherpage?ticket_id=ABC1234

The above should work? I'm getting myself in a right pickle with this. I've also now confused myself with "tick_id"; I may be incorrectly thinking the Request.QueryString requires "tick_id" to be defined in order it then passes the string "ABC1234".

Tried this quickly

Code:

<%=Request.QueryString["tick_id"]%>

which generates

Code:

Compiler Error Message: BC32017: Comma, ')', or a valid expression continuation expected.

I'm off to Hoxton now so will likely pick this back up again tomorrow.

I much appreciate your support (and patience) with this!

I am. Sorry I should have been explicit. Syntax within the html can't be that different surely ?

OK; sorted it. Need to define it in code.

Code:

 'Declare variable in global scope
    Protected Tick_ID As String

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        'set the value
        Tick_ID = Request.QueryString("Tick_ID")
    End Sub

Called via

Code:

 <iframe id="MyIFrame" src="https://website.domain.com/info.asp?ticket_id=<%=Tick_ID%>" scrolling="auto" width="100%" height="768px" frameborder="0"></iframe>
