you shouldn't use document.write after the page is loaded ... use innerHTML instead
kind regards
Thank You, I have included innerHtml now.
The problem is when i execute this in my firefox, The images are not gettinng refreshed(i mean window.setInter val() is not working). And i tried putting
<meta http-equiv="Refresh" content="30;URL =project.html"> but this is returning to the main page ie., It will again ask me to select the dropdownlist(as suming this code is named as project.html).
Is there any way ,where i can refresh only images directly. (Or )
As below, i should be able to call a function every 30seconds, ( but it is not getting the new data in this case.) When i execute this in my internet explorer, i am able to see that the images are being refreshed every 30 seconds, but to my surprise i dont see any changes in the image. I am using webservices link as image, where the url remains remain, but the graph keeps changing, but in this case it is redrawing the old image not getting the new image. When i again click on the submit button, i am able to see the new image.
Help me out..

you have the following errors:
please fix func2 so that graph is valid html and the method is getElementById( ): -
function func2() {
-
if (ld=='chennaigrad') {
-
var graph ='<table><tr><td><img src="..... some url , which returns an image got from webservices"/></td></tr></table>';
-
-
var d = document.getElementById("sometext");
-
d.innerHTML = graph;
-
}
-
window.setInterval("func2();",30000);
-
}
next fix your div to a valid node:
[HTML]<div id="sometext"> </div>
[/HTML]
kind regards
I did so, and i still has the problem.
Is there any way where i can reload only my images?
Here I am Calling a function for every 30 seconds and iam displaying those images in that function .
The main problem is , I am able to see the image for the first time when i click on the button, but later the function is being called but i dont see that the image is again the same. Its not getting updated?? is this any cache problem or so?? if so , how can i overcome it??
Thanks
--Alex.

add a unique querystring to the src: - src = '"your_img_src?d=' + (+ new Date) + '"';
kind regards
I changed the code accordingly, but as i am using webservices url, it doesnot end with some .jpg or .gif etc., and when i am using this code for that source, i am unable to see the image at all.
What does this date function do. where can i specify the delay as 30 seconds in this. ?

Hi,
I know how can I cache the ASPX page or any control on this page.
But how can I refresh ASPX page automatically every xx seconds? Any script?
I need my application to go to the server and reload automatically some data
from the database. I can place some code to On_LOad, but I suppose that
there is more official and easy way to do the same.
Thanks,

Hi there.
I am using SmartNavigation="True" in one of my pages and it is working
except for one instance. If I hit the browser refresh, or a button on my

60 seconds. When this is fired the page scrolls back to the top. Is there
anyway around this? Thanks for your help.
