I have a grid view populated with enough data to warrant a scroll bar. The RowDetailsTemplate contains a RadTabControl with multiple tabs. Given that I am on the 3rd (or any tab > 1st) and start scrolling the grid up (via mouse wheel or grabbing and dragging the scroll bar) when it reaches the top of the content of the RowDetails, instead of continuing to scroll it starts tabbing through my RadTabItems in the RowDetails. Is there a was to prevent this behavior from happening?

Hi Christopher,

The behavior you are describing is really strange. We have never experienced such an issue. Could you please check our FirstLook demo where the scenario is similar to yours? Let us know if you managed to reproduce the problem there. If not, please send us your xaml or a sample application so that we can see what is going wrong. Thank you in advance.
 
Kind regards,

I am able to see the same issue with the FirstLook example.
    1) I scroll all the way down and choose the last record in the grid
    2) I choose either the first or second tab in the rowdetails
    3) I scroll up to the top of the grid (Using both the mousewheel and the scrollbar itself).
    4) The RowDetails now has the first tab selected.

This also appears to happen if you expand the 1st and 3rd records, scroll down just enough to get the rowdetails of the first record off of the top then back up and that first record will change back to the first tab in the rowdetails.

After playing with the FirstLook abit more it looks to me like if you can get the full record with rowdetails to scroll off of the visable grid (up or down) that it scrolls through its tabs, or resets it to the first tab.

Hello,

 This is expected. The grid is UI virtual component and when you scroll up/down rows (and details templates) will be recreated (reloaded).
