    We have used KendoUI grid (v2013.2.918) control in our application with Detail template. We observe that when rows selection changes it is taking time to get the row selected.
    Is there a known issue with the performance of selecting grid rows in IE (11, 10, 9)?
    While it is working fine in other browsers (Chrome, Firefox etc).
    Do we need to handle anything specific? Please suggest.

    Hello Raj,

    Row selection becomes slower when grouping and/or hierarchy is used, because the :not CSS selector is slow in Internet Explorer and this selector is used internally by the Grid. Performance is improved in the latest Kendo UI releases, so you can consider upgrading. Still, selection will be always slower when hierarchy is used, compared to the case when it is not used. Using a smaller page size is recommended.
