Performance of Treeview with UI Virtualization

[Helmut Wahrmann]

Hi,

i was exepecting a Performance boost using Treeview with Virtualization enabled.

But it seems that the component has troubles with it.

i am displaying a folder structure and when a sub folder has like 1000 or more sub folders, the loading time is very long.

i was expecting that the UI Virtualization already starts rendering the first entries while the rest is loading.

just to see what i mean, use your own UI Virtualization sample, which you deliver with the product.

When you run the "1 Million" items that is fine, if you have 1000 modules in the root level with 100 sub modules each.

But now simply change the for loop in your sample to create 100 modules with 1000 sub modules each.

And then expand one of the nodes and you see what i mean.

This is not different than to using it without Virtualization.

Thanks,

Helmut

Hi Helmut,

Thank you for contacting syncfusion support.

We are working in new SfTreeView with flat hierarchy model for better virtualization of UI. The new control will get included in our upcoming Vol2 release by end of June which will meet your performance requirements.

Hi Duraimurugan,

the Performance sample for SFTreeView is impressive compared to what i have seen before.

Now i need to figure out, if all features of the TreeViewAdv are already/still available.

thx,

Helmut
