Hello,

 I want to add another keyboard options to the up/down/right/left navigations.

Suppose that I want that the w key will be like 8 key, and s will be like 2 key. I mean that w will travel up to the upper row, and s will travel down to the next row.

Thanks...

The paging (e.g., page up, down, home) keys are handled in the grid's OnKeyDown override while the navigation keys (e.g., right, left) are handled in the OnPreviewKeyDown override. That said, if you want to inject yourself into this behavior you have 2 options:

1- Derive from DataGridControl and override the OnPreviewKeyDown event to do your handling either before or after the base implementation is called.

2- Handle the DataGridControl's PreviewKeyDown event, which will be raised by the OnPreviewKeyDown method and only after the built-in navigation mechanism has been done.
