TreeGrid slow response on search

[Deepak Jain]

Hi,

I am using syncfusion treegrid in my Angular 8 Project.

I have total of 500 records with 5 levels of child data. and I am using external html input to search the tree grid with this.treegrid.search('myString');

With this case scenario treegrid response is slow on search, even in syncfusion example(link below) where treegrid default filtering, response is slow.

 

Also treegrid response is slow when I open/close the child nodes.

Can you please check what may be the issue ?

Hi Deepak,   

We appreciate your patience. 

Query#:- TreeGrid slow on Filter and Search:- 

Further analyzing, by default for search/Filter operation, we have to find hierarchy data recursively respective with the hierarchy mode .In your scenario, you have used large number of records(with multiple levels of child records). If nested level increases it will cause some sort of delay on these actions.  

To overcome this, we suggest you to show Waiting Popup(on search/filter action), and by default waiting Popup will be shown or else you can use your own customized Waiting popup on these action. Otherwise you can enable Paging to improve the performance. Refer to the documentation link:-

Query#:- Treegrid response is slow when I open/close the child nodes. 

 

Also, we have added (delay in Expand/Collapse action) as Improvement “Performance issue on Expand/Collapse action while using Large number of records”.
