How to deal with large amounts of data with TreeGrid

[qx5Participant]

I need to process thousands of pieces of data.They have a lot of columns
But I can’t turn on paging.
Now it takes ten seconds to load every 1000 pieces of data.
After loading, the event response of the list is also very slow.
How can I improve rendering speed?
Expresses I most sincere thanks in this.

Hello qx5,

Could you clarify it?
We have a lot of topics related to this or similar cases.
Please, take a look at this demo.
The data is loaded on demand.
Also, this topic, too.

Hello Hristo,
I’m sorry my English expression is not very good.
Now the situation is,I need to process a lot of data without paging.
I can’t turn on paging because of business requirements,so the page reaction is very slow.
How can I improve rendering speed?
Expresses I most sincere thanks in this.

Hello qx5,

Unfortunately, there is no virtualmode feature for scrolling for the jqxTreeGrid.
The only possible option is to load records on demand for the newly expanded item.
On the other hand, you could use our Smart.Grid with the Tree Grid mode.
Please, take a look at this demo:

It is also part of our products – the Smart HTML Elements library.
