I have been having a lot of trouble getting IFrames to work. Can someone show me how to use IFrame to embed a remote web page into the current aspx page?

Just put the code like this somewhere in your body:
<iframe id="Iframe1" src="http://www.wrox.com"
                    style="width:300px;height:300px;"></iframe>

or send more specific info about the problems

oh yeah sorry I should have been more specific, I need to be able to change the page which is displayed programatically. Is there any way of accomplishing that? Effectively changing the src according to user input?

You do this:
<iframe id="Iframe1" src="<% getUrl() %>" style="width:300px;height:300px;"></iframe>
and then in your code behind
dim url as string
sub someClicky()
url = textbox1.text
end sub

public function getUrl()
return url
end function

I have been trying that in C# and it doesnt seem to be working.
code behind:
protected string getUrl()
    {
        return Session["theUrl"].ToString();
    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        Session["theUrl"] = "http://reuters.com";

    }

ASPX:
<iframe id="Iframe1" src="<% getUrl(); %>"
    style="width:729px;height:594px;"></iframe>

I will try it and paste the code. Just a minute.

Sorry I left out a small item that makes a HUGE difference. its:
src="<% =getUrl(); %>"

the = tells it to send the returned value, basically

Same as
src="<% response.write(getUrl()) %>"

Either will work.
I never use the ; inline in the aspx files either, but I dont program in c much, so im assuming you know what your doing there:)
ciao!

click

Thanks A lot Works like a charm now!
