Arrow Key Navigation | Infragistics Forums

Hi,

the left - right arrows should move the next- previous cells even they are in different columns.

The word "columns" gets a little fuzzy when dealing with CardView mode. I assume you want the arrow keys to move in an intuitive direction, so down would move to the next cell within a card and right would move to the next card, same cell.

Here's some code that works in both CardView and non-CardView mode.



        private void ultraGrid1_KeyDown(object sender, KeyEventArgs e)
        {
            UltraGrid grid = (UltraGrid)sender;
            UltraGridCell activeCell = grid.ActiveCell;
            if (activeCell == null)
                return;

            Keys resolvedKeyCode = e.KeyCode;

            // When in CardView mode, change the direction by 90 degrees. 
            if (activeCell.Band.CardView)
            {
                switch (resolvedKeyCode)
                {
                    case Keys.Right:
                        resolvedKeyCode = Keys.Down;
                        break;
                    case Keys.Left:
                        resolvedKeyCode = Keys.Up;
                        break;
                    case Keys.Down:
                        resolvedKeyCode = Keys.Right;
                        break;
                    case Keys.Up:
                        resolvedKeyCode = Keys.Left;
                        break;
                }
            }


            switch (resolvedKeyCode)
            {
                case Keys.Right:
                    grid.PerformAction(UltraGridAction.NextCellByTab, false, false);
                    grid.PerformAction(UltraGridAction.EnterEditMode, false, false);
                    e.Handled = true;
                    break;
                case Keys.Left:
                    grid.PerformAction(UltraGridAction.PrevCellByTab, false, false);
                    grid.PerformAction(UltraGridAction.EnterEditMode, false, false);
                    e.Handled = true;
                    break;
                case Keys.Down:
                    UltraGridRow nextRow = activeCell.Row.GetSibling(SiblingRow.Next);
                    if (nextRow != null)
                    {
                        nextRow.Cells[activeCell.Column].Activate();
                        grid.PerformAction(UltraGridAction.EnterEditMode, false, false);
                        e.Handled = true;
                    }

                    break;
                case Keys.Up:
                    UltraGridRow prevRow = activeCell.Row.GetSibling(SiblingRow.Previous);
                    if (prevRow != null)
                    {
                        prevRow.Cells[activeCell.Column].Activate();
                        grid.PerformAction(UltraGridAction.EnterEditMode, false, false);
                        e.Handled = true;
                    }
                    break;                    
            }
        }
