[question] DataGrid row virtualization issue, rows not appearing on scroll

[ttackett06]

The problem in depth

When using the DataGrid component, only a subset of the rows are being displayed properly (as expected with virtualization), but upon scrolling down, additional rows are not being displayed. I know the rows are there, because if I click on a dropdown link in the sidebar, a subset of the rows will appear in the blank space of the DataGrid, and all other rows will not appear. Seems as though the scroll is not triggering the rows to display, only the click of a dropdown link.

Can you fill the npx @mui/envinfo section? Where are you seeing this? With which version (library & browser)?

[ttackett06]

Yes, sorry about that...I have updated the @mui/envinfo section.

[romgrk]

Could you test with the latest version? Could you also provide a reproduction case? Are you seeing this on the docs, or in a project of yours? If you see this in a project it's important that we get a reproduction case.

[ttackett06]

I am seeing it in a project of mine...I have been unable to reproduce the error with mock data. The latest version does not seem to be helping the issue. We are not using Lazy Loading

[romgrk]

We need much more details to be able to help you. A reproduction case is particularly important because it helps us assert where the problem is. If you can't reproduce it outside your environment, it might be caused by code or customization you have added that we are not aware of.

In the very rare cases where it's impossible to provide a reproduction, we at least need screenshots, stacktraces, and a detailed description of your use-case and what you're doing with the datagrid.

[ttackett06]

I was finally able to recreate the issue using CodeSandbox...we are using our own custom CommonGrid which is included in the sandbox. Here is a link:

[romgrk]

The link leads to a sandbox that doesn't exist, or the permissions for that link may not be set properly for sharing.

[ttackett06]

My apologies...I believe I have fixed the permissions now

[romgrk]

There seems to be an issue with the rowThreshold prop. If it's removed, virtualization works again. What value do you set to it? What if you set it to its default value?

[ttackett06]

Thank you so much...this fixed the issue!
