I'm loving jqgrid but I have a question-

I used jgrid to display a queue (basically, it just shows the data in a table) - the data on the backend changes periodically so I want to refresh the grid or certains cells when those changes occur. For now, I'm using the 'loadComplete' function, the native js setInterval, and the jqgrid function trigger:

jQuery("#list").jqGrid...

... loadComplete:startAutoRefreshing

function startAutoRefreshing(){

      setInterval(function(){
                jQuery("#list").trigger("reloadGrid");
        },10000);
}

Is there a better way to do this? More importantly, I have a problem - the refreshes seem to take longer and longer. If I load the page, after 10secs I see the 'loading...' notice pop up for a second. Ten seconds later it pops up for a little longer. After a few minutes, it pops up for the full 10 secs - effectively it never goes away.

Any thoughts on why this is happening?

Thank you!

Interesting, since this seems weird (I mean why it would take progressively longer upon each request). So can you please try the following, instead of using the loadComplete event, set a global setTimeout handler for that, e.g.

window.setTimeout( startAutoRefreshing, 10000);

and see if you get better results?

Hello,

I think that adding this to loadComplete is not a good idea.

You should just after the grid is loaded do (NOT in any grid event)

setInterval(function(){ jQuery(”#list”).trigger(”reloadGrid”); },10000);

Which will refresh the grid after this interval

Thanks for all the help - Tony and Rumen - I thought that I had tried the simple setInterval option that Tony suggested but I must have messed it up because I just tried it again and it works great!

Thanks again!
