Window - loading image whilst PDF loading

[JK]

Hi,

I have a fully working radwindow which obtains the PDF from a SQL database and "Writes" the results to the page (within the window).  As a result I need to have the "ShowContentDuringLoad" set to true (otherwise the page would not be displayed).

The problem is the PDF being downloaded (depending on broadband connection) makes it look like the web browser has stopped responding for some of our more impatient users.  Is there a way to put a comment or image to indicate its still loading whilst it is pulling the file from server?

Oh the ironry!  I need ShowContentDuringLoad both on and off ;o)

Here is the sequence of events within the web page:

1. click link
2. opens radwindow
3. radwindow pointing to another aspx page.
4. this page (ASP C#) writes results to page.

Thanks in advance.

Hello JK,

I'm afraid this is not possible when you load the PDF directly in RadWindow. Yes, you could show a loading image, however the problem is that you will not "know" when to close it. The PDF does not fire any events so there is no such way that you could use to detect that the PDF is loaded and stop the loading animation.


All the best,

I've done something similar to this ages ago. The trick is to load the PDF in an IFRAME hosted in an aspx and listening for the onload event on the IFRAME:

<script>
    function PDF_OnLoad(){
        //hide DIV here
    }
</script>

<iframe src="mydynamicpagewhichloadspdf.aspx" onload="PDF_OnLoad();"></iframe>

With some css trickery you can place the loading div over the iframe whilst its loading.

Thanks
