Multiselect large data set

[Emir Prcic]

Hi,

I have implemented a Multiselect control with Filtering. It contains more then 10k items. My initial load is only 50 items as default items and all others need to be found over the filtering. 

When user filters and select various items and saves them everything works as expected. But when I load my edit page and patch values I see in tags only the values that are in the initial load (50 items). So if I have selected and saved one outside the first 50 it is not visible in edit mode. And this is also ok us I understand it per documentation: 

https://www.telerik.com/kendo-angular-ui/components/dropdowns/api/MultiSelectComponent/#toc-value

All selected values which are not present in the source are ignored.

It works if I load all items in the multiselect but with 10k items its not very good for performance reasons. What would be a better approach.

 

Thanks

Hi Emir,

The brute-force solution to be to load all items and use virtualization to lessen the performance impact. This is not ideal, as you've noted.

A better approach would be to include all values that are currently in use to the list of initial values. This may prove to be challenging, depending on the number of data sources in use. I'm afraid there's no built-in option to do this.
