  4. when I refresh treeGrid after reset dataSource, It's very slowly.

when I refresh treeGrid after reset dataSource, It's very slowly.

Hey, I met a problem when i use virtual treegrid.

There are some of actions to CRUD the data, and when the remote data was be changed by other user. i need to change the datasource and refresh treegrid, it is almost 50k rows.

and when I reset datasource by change treegrid.datasource, the data will start from error row, and show same page when i tried to scroll.

but when I use 'splice' to change datasource, 'refresh' is very solwly, and make the browser be stuck.

Hi,because the refresh will make the browser be stuck, I tried to use addRecord, deleteRecord, updateRow to CURD the visible table.But when i use 'addRecord' to add record as 'Child', it showed error index. when i use 'deleteRecord', when i delete child of parent one by one, the expand icon will miss, the parent row still have children.

and there is video to record my action

  1.  When I reset datasource by change treegrid.datasource, the data will start from error row, and show same page when i tried to scroll.

Further analyzing, we have already logged the defect report for the same scenario. The fix for this issue will be included in our First weekly patch release(expected to be July 13, 2022) after Volume 2, main release

       2)    but when I use 'splice' to change datasource, 'refresh' is very solwly, and make the browser be stuck.

 

We have prepared sample and changed the dataSource using Splice but we are unable to replicate the problem at our end. Refer to the sample link:-

https://stackblitz.com/edit/angular-fcb1gw-ck6mzo?file=app.component.ts

 

So share us the details such as Time delay you have faced with Video demo or replicate the issue in the above sample and revert us for further validation.

 

 
  1. when i use 'deleteRecord', when i delete child of parent one by one, the expand icon will miss, the parent row still have children.

 

 

 We are able to replicate the problem from your provided details. On further validation, we have confirmed this issue as a bug and logged defect report for the same “Parent Icon disappears when we delete the multiple child records, still child records are present”. Thank you for taking the time to report this issue and helping us improve our product.

Hi Simon Li,


Sorry for the delayed response.


The reported problem “Data replicates on scroll on changing the datasource” and “parent Icon disappears when delete multiple records” has been fixed and included in our latest release. So we request to upgrade into latest version 20.3.47 or minimum of 20.2.38 to resolve the problem.
