Performance Listbox - first click on "select all"

[fabius916]

Hi there,

I have a very slow perfomance on the first click of the "select all" control of the Listbox. From the second click on, everything runs smooth, but the first click sometimes takes seconds to execute.

Even in the demo it is noticeable, that the first click takes longer.

Is there any solution for this?

This appears to be an issue that I also recently commented on this thread, except with the RadzenCheckboxList:

Radzen Treeview - Limits

I'm also experiencing something similar with a checkboxlist... I get a random time delay between click and update on the first check only. Any subsequent checks happen instantaneously. The delay can be over a second or more at times. The delay shown happens when I click at 06:21 (when the pointer highlight expands) in the video. [Radzen checkbox click delay]

Can you try this: Radzen scheduler takes time to load - #9 by korchev

It seems to have resolved the issue with RadzenCheckboxList on my end.
