Using with a large data source

[Brian Vallelunga]

I need to use MultiSelect with a large data source (15K+ items) and am trying to figure out if this is possible with reasonable performance. I've enabled server-side filtering, but the control still tries to pull down the entire list of items on initialization. Part of my dilemma is that one client has 10K+ items that are all in the format of: 12345***** where the first 5 characters are always the same. I think ideally the control would have some sort of virtualization where it could pull down a page of data at a time while the user scrolls through it.

Are there any tips for working with the control using large data sources?

Hi Brian,

You can use the autoBind options in order to prevent downloading of the whole list when the MultiSelect is created, and you can also change the minLength property, so the list will be filtered on the server and return a smaller number of items.

As for the virtualization option of the popup with the suggestion - this is currently not supported.
