Issues with Web grid

Hello,

I attached my simple sample. It used dsNorthwind dataset from WebGrid sample. I think the checkbox might be slow at the first. But for the next, I think the performance still acceptable. If you found some steps to show the bad performance, please let me know.

Hi Surya,

I am also facing same issue.
In the above link you have provided, there is no option for checking the rows, Can you please provide a link which has a check option at the child level.

Hello Suhas,

If that also happens for two levels, it would be not acceptable.
Please try to see our hirarchical sample in this link. It does not have 4 levels, but 3. As you can see in two levels, and next levels, it only took 2-3seconds to load. If you see 'Blaus', it has 7 rows, and it does not take 10seconds.
That's why we also need a sample from your side. Perhaps there is something wrong with your databinding or something.

Handy

Hi Surya,

I don't think a sample is required. My recent analysis says that it can be identified even in 2 level.

1. Just have a 2 level hierarchical grid which has 300 or more child rows for any of the parent row. For both parent and child check box are rendered.

2. Expand the parent row that has 300 or more child rows and then try to check the parent row.

3. Checking of parent row takes more time (More than 3 to 5 seconds).

If you have any working sample, please try the same scenario. it should be replicable.

Can i get the performance analysis statistics document for web grid? So that we can share it with our clients who reported these issues.

Also if there is any live demo page where in clients can try the check box scenario, it would be great.

Regards,

Hello Suhas,

I think it is better to wait a runable sample that replicates the issue first in order to know more details what happened. I suspect there might be something wrong with your databinding or something.

I have tried that also and performance improvement is not there. As i mentioned in my previous post, i removed all customizations done on Web grid and then tested for the functionality. Clicking top most row when all its child rows are expanded takes time around (4-5 seconds).

Hello Suha,

Please remove those scripts and let me know if the performance issue still persists when expand the row (levels).

Actually we are having a custom javascript method to check the check boxes as it is a bug. The execution time of that method is around 2 Seconds excluding check events. Including that it is around 8 seconds.

The demo that i have attached, includs our custom scripts where in i am looping through all the parents and check them if the child is checked and vice versa.

To analyse further, i commented our custom javascript calls and tried the same scenario and found following behavior (Scenario is same as that i have attached in my previous thread).

1. If i do not expand and check parent row, checking operation very fast.

2. If i expand first row and then click on top most row, the performance degrades a bit and so on.

Also after applying the hot fix, i still have the same problems.

Thanks for your support. Please let me know if the fix is ready for issues.

Hello Suhas,

Thank you for your video. However, we would need to investigate the sample to know what is causing the slow performance. For checkbox issue, it has been reported to our developer teams.

Thanks for the help. I will apply the patch and try the scenario again. Please find the video file in attachment where in i have shown the performance issue.

I will update once i finish applying the fix and testing. I will work on the sample and provide it. There might be a delay in providing the sample as we are nearing product release dates.

Thanks a lot,

Hi,

I am facing following set of problems.

I have hierarchical grid of level 4. For each parent i have at least 20 item at first level, 10 items for subsequent child levels.

Performance issues:

1. Expansion of row takes more than 5 seconds.

2. If all Child rows are expanded for a particular row, checking (Check box enabled) of top most parent row takes more than 2 seconds as well as un checking. How ever, if the parent row is not expanded, checking and unchecking is very fast.

3. Once rows are checked, if we do any operations like group by or load more, checked rows are not persisted. though i have manually written javascript to check the rows in post back scenarios in order to persist the checks (This issue has been posted already in the community).

dll name : ISNet.WebUI.WebGrid.dll

dll version : 7.0.7200.401

Please assist me on how can i resolve these issues. Fix would be appriciated.

Thank you,

Suhas T J
