Hi,
You can use keyboard to navigate cells. However arrow key can move the current cell only when the cell is not in edit mode. You can see how it works with this demo:
http://demo.essentialobjects.com/Demos/Grid/Features/Keyboard%20Navigation/Demo.aspxHere are a few steps you can do:
1. Click cell "A". This cell will enter edit mode;
2. To move to cell "B", you will need to use tab key (not arrow key). This will also cause cell "A" to leave edit mode;
3. Since no cell is in edit mode now, you can use arrow key to move the current cell freely. For example, use down arrow to move to cell "D";
4. If you want want the current cell to enter edit mode, press Enter. For example, if you are currently on cell "D", you can press Enter to put cell "D" in edit mode;
Note in order for arrow keys and tab keys to work, you will need to set EnableKeyboardNavigation to true.
Hope this helps. Please feel free to let us know if you still have any questions.
Thanks!
