Grouping WebGrid rows has a large performance issue

Hello,

Unfortunately, there is nothing we can do anymore. If there is, we will do it for you. This make imposible for us because the limitation comes to the browser itself. Unless IE9 fix their rendering, there is nothing we can do. Once again, I hope you understand what we were trying to say. It is not that we refused your request. But we have tried to see the possiblities.

Regards,
Handy

Grouping WebGrid rows has a large performance issue

Yudi,

As we have already discussed, I am unable to use any of the solutions you have provided:

Our application supports IE9, as does your WebGrid control. I cannot ask users to upgrade their browsers just to achieve acceptable performance.
Classic paging is a worse user experience than the current setup.
The collapsed grouping had only minor performance benefits (10%), and is also a less desirable user experience.

I am still using WebGrid in a recommended way, in a supported browser, with a small amount of data. I desperately need it to perform better under this simple configuration. Can your development team please provide another hotfix to improve the rendering?

Thanks.

I have tested the sent nightly-build hotfix of WebGrid on the provided sample and found that the elapsed time almost identical with the previous test. I also perform a test on IE 10 browser using the same sample project and WebGrid’s assembly. Although the rendering time is not as good as Chrome, Safari, or Opera browser, the IE 10 browser can render the sample page better than IE 9.

Our WebGrid development team has tweaked the JS code in order to optimize the rendering process on client. However it is obvious that the browser engine which cause the reported problem.

There are some options to improve the rendering process as follow.

Try to use other browser such as IE 10 or Chrome or Safari or Opera.
Try to enable classic paging feature.
Try to set the GroupMode to Collapsed.

Please let us hear your response.

Yudi,

Thank you for responding. I have replaced the DLLs in my sample project with the ones you sent in the pre-release, and have rerun all of my tests. I found that the new DLLs have 0% improvement over the old ones. Running both samples side-by-side gives the same results.

Can you please try the sample I provided earlier with the new version of the DLLs and confirm my results?

Thanks.

Apologize for the delay in sending this. We had internal network problem in the last couple of days.

I have sent you a message to your registered email account. The message contains a link to download the pre-release assembly of WebGrid. Please kindly check your inbox and let us hear your response.

Hi Yudi,

I'm just checking in again to see if the hotfix that you mentioned is available yet? If not, can you please let me know when to expect it (ie: calendar date)?

Thanks.

Hi Yudi,

I'm just following up to see if the hotfix is available yet? If so, please let me know how to get it.

If not, please provide an estimate (calendar date) of when it will be ready. I need an estimate so that I can plan changes to my product based on when the hotfix is available. This issue is very important to me and my clients!

Thanks.

There is no patch/hotfix yet for the performance problem in IE 9. When ready, I can provide you with the pre-release hotfix to be evaluated on your end.

Thank you and have a nice day.

Hi Yudi,

I'm a little confused by your response -- when you say that "there is significant improvement after the touch up", does this mean you have a patch/hotfix that I can apply? If so, how do I get it?

Thanks.

WebGrid development team does their best to optimize the rendering performance on IE 9 browser. We expect that there is a significant improvement after the touch up.

However, there is nothing that we can tweak further if it deals with the browser’s engine.

I am currently experiencing performance problems when grouping the rows in a WebGrid.

The attached example contains a page with a WebGrid containing 400 rows. With no grouping, the grid renders and displays the 400 rows nearly instantly. However, adding 4 grouping columns (required by our application) causes the grid to take much longer to render ( approx. 11 seconds). Adding the group totals (also required by our application) further increases the render time (approx. 30 seconds).

You can reproduce my results by changing the "ADD_GROUPS" and "SHOW_GROUP_TOTALS" variables in the example page code. Also try refreshing the page multiple times to see that the rendering performance is poor on all postbacks as well.

Can you please provide one of the following:

Instructions on which settings to change to improve the performance of the grid with grouping enabled, or
An update to WebGrid that fixes this performance issue

Thanks!
