Hi,
I have a problem with the Kendo grid when i click on a row for select it.When it's at border between the grid's bottom, it's shift up and don't select it.
e.g :
http://dojo.telerik.com/@muadhib/opena
Click on the line Brazil (Freight : 58.17, Order date : 10/07/1996), the line shift up at the third position. Be warn, a new line Brazil appears a last row, but it's not the one i want ! (In my case, my window is in resolution 900x 607 and i'm using Chrome)
I seems to be caused when the grid is on scrollable: { virtual: true }.
Any body have the same problem ? What do i wrong ?
Thx

First, as documented in the following help articles, you need to have set "height" for the Grid in order for the scrolling to work correctly. Additionally, paging and selecting are not supported with the virtual scrolling:
- http://docs.telerik.com/kendo-ui/controls/data-management/grid/walkthrough#virtual-scrolling
- http://docs.telerik.com/kendo-ui/controls/data-management/grid/appearance#virtual-scrolling
As for the problem that you are describing, it is caused by the enabled "navigatable" functionality, which scrolls the items when you click on the last row and if it is not entirely visible.
With all that in mind, if you are going to use the virtual scrolling you have to disable the row selection and/or the navigatable functionality.

Hi Konstantin,
Thanks for the reply.
So, this feature, which worked in version 2013 and which been supported, doesn't work any more ?
Indeed, it's work with disabling navigateable, but i need it. And it was working before I update the version.
Can you give me what is the utility to use your grid in virtual if we can't select, navigate, create, update, delete, add large datas ? Just read data ?
I'm very tired to work with your product. All interesting features disappears in each update. And all your answers are : "Not supported", "Not a bug because we don't know how to fix it", "Write a workaround".
What is the vision for your grid ? Increase and improve features or it will be deprecate in future ?
I need to know where you want to go and check if we are still in an agreement.
Regards.
The current behavior of the navigatable is made that way on purpose, because in previous versions (where clicking on the last item does not scroll the grid) prevents scrolling when you move through the items with the keyboard (making the current item out of the view). I understand how this might be considered as a bug, but the active cell should be visible and that is why clicking on the last row is scrolling the view.
As for the other features that are not supported with the virtualization, please note that they are limitations due to the way the virtualization works. The virtualization is suitable for a scenarios where there is a huge amount of records that need to be displayed. In case other features are required, the virtualization should be replaced with the paging functionality.

Hi Konstantin,
I understand why it's scroll up when we are in navigatable. It's a good feature ! But, I don't know why the row isn't selected in same time. Users can be surprised because they lose there marks, the row move and the selection isn't working. Isn't it ?
I understand when you tell it's for show much datas, I'm just surprising because it was working in older versions. Is it in the roadmap to improve the virtualization ? Our users use it since 4 years. I can't tell them "Now, you can't use this because it's not already supported".
Regards
If you have some suggestions for the improvement of the virtual scrolling you can create a feature request in our feedback portal:
