Possible bug in SfDataPager changing rows per page

[Fernando de Miguel]

Hi everyone!

There seems to be a problem with changing the number of rows per page depending on the number of elements in the data source.

How to reproduce the error:

- Take the SyncFusion example of SfDatagrid paging.

- Change the _rowsPerPage variable and give it a value of 25.

- Change the number of elements in the data source. Replace 300 by 35.

- Change the possible values of the availableRowsPerPage property of the SfDataPager to [25, 50, 100].

- Change the pageCount property of the SfDataPager to (orderInfoDataSource.orders.length / _rowsPerPage).ceilToDouble().

Once these changes are made, the way to reproduce the problem is to navigate to the second page where the last 10 items are displayed, change to view 50 items per page and what happens is:

I also attach the example file with the modifications applied.

By the way, is it better to put this post here in the forum or in the feedback portal? where is it better to put it?

Greetings

Fernando,

We are glad to inform you that the reported issue regarding the “The DataPager did not function correctly when updating the rows per page at runtime” has been resolved. This fix has been incorporated into our latest weekly patch release. To benefit from this fix, we recommend updating your DataGrid package to version 24.2.7.

https://pub.dev/packages/syncfusion_flutter_datagrid  

Root Cause of the issue:

The issue arises from the DataPager failing to properly update the current page when rowsPerPage changed at runtime, leading to this discrepancy.

We thank you for your support and appreciate your patience in waiting for this update. Please get in touch with us if you require any further assistance.

Regards,
