Browser crashes with Grid

[elder1]

 Hi,We are experiencing a serious problem with the Grid!When loading a page with the Grid on it the browser will completely freeze.The only solution is to use Task Manager to kill the browser instance.Let me explain the setup:The customer is using Internet Explorer 6.0We are using SharePoint 2007We are using AJAX, so content can be updated without a page refresh.AJAX is integrated from .Net Framework 3.5I have created a class library for a SharePoint WebPart.This creates an UpdatePanel and adds the Grid to the UpdatePanel.I have used this exact same technique for some Charts and have not had this problem with them.We have GridFX Ver. 1.0.3007.30962The GridFX is licensed on a production server.The GridFX PSS service is started and running ok. This problem seems to be intermittent. Sometimes it works ok.This is just a hunch but it seems if you mouse over the grid when the page is still loading then the problem is more likely to occur.I know lots of Javascript is loaded by the grid.I guess lots of clientside events are fired when mousing over the grid.Is there anything in this that could crash the browser?Can I turn off the clientside events?What can I do to track down the cause of this?Thanks for your help.Chris.

Hi,

Thanks for the message.  You included all the information I needed, which is really helpful.

I am trying to replicate the problem here.  With the latest version of Grid FX, I cannot reproduce this problem.  We have been doing some work actually to get Grid better integrated with SharePoint.  We will be releasing a service pack soon, but if you want to try it immediately, I could get a hotfix for you.  Would you like to try that?

Update!

This is happening everytime a first time user tries to load the page with the GridFX.

The browser will completely lock up and does not unlock even if we wait a long time. I have to resort to killing the browser and starting again.

It seems that once the Grid is loaded (I assume the js files are cached) then it works ok.

This is not acceptable as the roll out to the users will generate huge amounts of support issues.

Any ideas?

Is GridFX safe on an UpdatePanel ?

Is GridFX safe to use in SharePoint 2007 ?

Any help appreciated.

Chris.

 Hi,

After I have restarted the browser a couple of times the page with a Grid will load fine. I can hit refresh and it reloads ok.

If I then empty the Browser cache (remove all offline content) the browser crash will occur again.

I can use Fiddler to record the http traffic. The last call before the browser crashes is a GET request for Gridresource.axd

I will test the hotfix if there is one.

Thanks,

Chris.

 Further information:

 

On IIS for the affected site I set DoDynamicCompression = false

and the problem went away!

I have confirmed that the ScriptFileExtensions contained "axd"

 

So to summarise:

Using Dynamic Compression in IIS6 for content served through GridFXResource.axd causes an intermitent timing issue that locks the browser.

We have IE6.0 on all clients

Win2K3 Server and SharePoint 2007

 

Thanks,

Chris.

Wow Chris, good find!  I'm gonna play with that over here.  We gzip our script files so I wonder if some kind of "double compression" is occuring that is causing the real problem.  If that's the case, I will include a way to disable our script compression so you can keep IIS's settings.  Thanks again!

I'm having the same issue with users running IE6. Tried setting DoDynamicCompression to false and still no luck. Also noticed that your demos http://demo.softwarefx.com/gridfx/ don't work in Google Chrome either. Any suggestions?

FYI - If the affected IE6 user un-checks "Use HTTP 1.1" under Internet Options, Advanced tab in thier browser settings, it works. Still would rather find a server sided fix though.
