    My application requires to have grid navigation with up/down arrow keys and this is working, however, changing the selected row does not generates

    raises the SelectedIndexChanged in the server side which I need to execute some other code to populate a panel with other information. The  SelectedIndexChanged  is only raised if a row is selected with a mouse click, and I need it to happen when changing the selected row with the arrow keys.

    How do I need to configure the Grid to support this behavior?

    The keyboard navigation of the grid with the arrow keys actually changes only the active row, the section is triggered only when you press the spacebar key.
    If you wish to also select a row while navigating with the arrow keys then you can handle the OnActiveRowChanged client-side event and then select the current active row through the client-side API of the grid:

    This should select the row and also trigger the SelectedIndexChanged event when a postback is initiated. If you have set EnablePostBackOnRowClick = "true" then a postback will happen only when you click the row with the mouse.

    I hope this helps. Let me know if you have any other questions.

    thank you, I actually ended up not requiring a post back, but your information was still very useful.
