[CLOSED] Question about TreeNode rendering

[rosua]

Hi, Daniil.

This question is a little bit tricky.
If there is over 1000 nodes to display on webpage, website reaction is slow/delayed.
For example, mouse over action is slow on dropdown box, and webpage scrolling is slow too.
We can't use pagination because there should be sum of data called "Total" at the bottom.
To fix this issue, I tried to use iFrame, but it didn't worked.
Please let me know how to resolve this issue.


Please see snapshot.

Hi,

Well, it means that 1000 nodes is too many for a browser. I'm afraid we can't help here, because it depends on a browser and its JavaScript engine.

What browser are you testing with? Internet Explorer? If yes, please try with FireFox and Chrome, it should work much faster.

You can send just this total count from a server. You don't need all these nodes on client to show just its count.

So, I would suggest to load nodes remotely.
