Back button won't fire grid load

Suite and Optimus Suite 5
#1

Hey there. I am using the dhtmlgrid and it’s working quite well. i ran into a glitch where if I fill out the grid with information, go to the next page, and then click the back button, the grid never gets populated with results from the LoadXML().

In the below, I will always get the alert() to fire up; however, the loadXML works if I’m hitting the page the first time (or explicitly), but if I hit the back button, the rest of the page will load with content but the grid control will be blank (even though it’s obviously getting to the LoadXML() call since the alert() after it fires.

Any help appreciated.
Thanks.

Check if you call grid initialization code after page is loaded:

[code]
…

function doInitGrid(){ mygrid = new dhtmlXGridObject('gridbox'); mygrid.setImagePath("/js/imgs/"); mygrid.setHeader("Location,Opening WIDTH,Interior DEPTH,Model Choice,Wood Front,Qty"); mygrid.setInitWidths("270,120,120,90,90,50"); mygrid.setColAlign("left,center,center,center,center,center"); mygrid.setColTypes("txt,coro,coro,coro,coro,coro"); mygrid.setColSorting("str,str,str,str,str,str,str,str"); mygrid.setSkin("dhx_blue"); mygrid.enableEditEvents(true,false,true); var dp = new dataProcessor("CustomerOrder.asmx/UpdateOrder"); dp.init(mygrid); mygrid.init(); mygrid.loadXML("CustomerOrder.asmx/GetOrder",function(){ alert('hi'); //call alert when all rows are loaded }); }[/code]

Heya, thanks for the response. Yeah, it was definitely calling it. Turns out the problem was that the web request url was cached (CustomerOrder.asmx/UpdateOrder), and so it never bothered calling it. I had to append a random number to get it to work (CustomerOrder.asmx/UpdateOrder?rand=234234).

Thanks.

You can disable xml caching using preventIECaching() method:

mygrid.preventIECaching(true);

It works for all browsers
