    Hi Team,
    In a locked column in grid, When tablet orientation change continuously multiple times with some fast speed, the selected row is dividend in different selected row for locked and unlocked column. This is a intermittent issue. While moving in slow pace this issue may or may not occur.

    Hello Ritu,

    I am not able to reproduce the described issue. Could you please provide more detailed steps to reproduce the issue and information about the testing environment? I tested the behavior with the following dojo sample - http://dojo.telerik.com/abOro . You could modify it if I have missed something and send it back to us for investigation.

    Hi Team,

    Scenario is not so straight froward, 

    Backbone view 1 --> kendo 1[virtual scroll true]

    Backbone view 2 --> kendo 2 [virtual scroll true]

    Render view 1, Navigate to view 2 and navigate back to view 1. Select a row in kendo 1, scroll up as the selected row is visible. Now change the orientation and the result is ->

    locked column will show the correct row which is scrolled up but the unlocked columns will show the first row of grid. which made the mismatch of selected rows.

    Scenario is little tricky, 

    Backbone view1 --> kendo grid 1,

    Backbone view2 --> kendo grid 2,

    Navigate from view1 to View 2 and navigate view1 back, now select a row, scroll up and change the orientation. 

    Result -> Locked column show the scroll up selected row but the unlocked columns show the grid with first row instead the scrolled up row position. it might be the issue of viewport of grid gets refreshed for unlocked columns somewhere when change the orientation.

    Hi Ritu,

    The selection in Grid for Kendo UI is not persisted when comes to virtual scrolling. Have a look at this article explaining the limitation of virtual scrolling:Virtual Scrolling.  Switching the orientation of the device should not interfere the selection. Make sure that you don't have any logic on window.resize and make sure that the component has a fixed height.

    However, we reviewed the scenario once again and tried to reproduce it but  to no avail. In order to investigate it further, please send us a sample in dojo.
