Height of Report Viewer embedded in iframe [message #990348]

I have a report embedded into a web page using an iframe.

I'd like to resize the main document to avoid a scrollar in the report viewer.

From what I've found out looking at the Birt jsp pages, the report scripts resize it to accomodate to its container height, adding a scrollbar if needed.

I would like to know when the report has finished rendering. Once it is rendered, I can easily find out its absolute height and let the main document resize to fit.

Is there a way to know when the report has finished rendering? An event I could be listening to?

Other ways of solving this scenario also appreciated.

regards,
Jordi

There is a report script event called afterRender. You might try there, first. From the designer, you can get there by clicking in an empty spot in the design window, then clicking on the script tab, below the design window, and selecting afterRender from the drop down.

Doesn't seem to being called.

I cannot see where the script is sent to the client either.

Is this script really run in the client(in the browser)?

I want to do something like this:

afterRender event script:
parent.updateHeight(document.getElementById("__BIRT_ROOT").scrollHeight);

Main document script:
function updateHeight(birtViewerHeight) {
document.getElementById("birtIframeId").style.height = (birtViewerHeight + 150) + "px";
}

So in effect I am forcing the Birt "Document" not to have scrollbars. I can do this manually with Firebug and it works, but the afterRender event script is not working.

Ah. No. That's server side. Sorry for misunderstanding what you were looking for. You can call client side script from and HTML text box using <script> tags. You should be able to pass info from the report using the <value-of> and <viewtime-value-of> tags.

Excellent, it is working now.

I put it in the Master Page footer, where the date text box is:

<page-footer>
<text id="3">
<property name="contentType">html</property>
<text-property name="content"><![CDATA[<value-of>new Date()</value-of>
<script type="text/javascript" language="javascript">parent.updateHeight(document.getElementById("__BIRT_ROOT").scrollHeight);</script>]]>
</text-property>
</text>
</page-footer>

Thanks Michael, much appreciated.
