I am using Kendo UI multiselect widget in my application in my application. But the page becomes slow and unresponsive with large data source. Approximately, the data source is more than 50 thousand. And we're using the same data source in about 100 rows of our html table. Essentially what I am looking for is to apply server filtering and update the data source dynamically on the fly when user types in any value( data source should contain only the selected values and the top 100 matching values). Any help regarding this would be appreciated.. great if a sample code base could be shared well..
