    I face a problem that with large data set, when first open/show, it will freeze the browser.

     

    I tried virtualization, but not working properly for me condition.

     

    My dataSource is added dynamically during runtime. 

     

    Please advice if there is any other solution/hack.

     

    Thanks.

    Hi,

    Here is a sample that showcases how to configure Kendo ComboBox with large data set:
    http://dojo.telerik.com/EWoGujUy

    In this example the initial Combobox data items are get using the data() method of the DataSource component and converted to JavaScript Array object using the slice() method. The new items are then added to the array and the datasource data is finally updated only once. In this way the performance is improved since the widget event handlers and rendering are not refreshed on each datasource change.

    I hope that helps

    Best Regards,
    Misho
