shift-space select row

[Daniel Chait]

Again trying to make the grid act like excel, i put the following code in grid_KeyDown:

if ( e.KeyCode == Keys.Space && e.Modifiers == Keys.Shift )
{
grid.EndEdit();
GridRangeInfoList rowSelections = new GridRangeInfoList();

foreach ( GridRangeInfo range in grid.Selections.Ranges )
{
GridRangeInfo rows = GridRangeInfo.Cells(range.Top, 1, range.Bottom, grid.ColCount);
rowSelections.Add(rows);
}
grid.Selections.Clear();
foreach ( GridRangeInfo range in rowSelections )
{
grid.Selections.SelectRange(range, true);
}
e.Handled = true;
}

which kind of does what I want, but ends up typing a Space key anyway. Suggestions?

I think you will have to derive the grid and override virtual methods to avoid processing the space.

Here is a first try at this.

public class MyGridControl : GridControl
{
	protected override bool ProcessDialogKey(Keys key)
	{
		if ( (key & Keys.KeyCode) == Keys.Space && Control.ModifierKeys == Keys.Shift )
		{
			Selections.Clear();
			Selections.SelectRange(GridRangeInfo.Row(this.CurrentCell.RowIndex), true);
			return true;
		}
		else
			return base.ProcessDialogKey (key);
	}
	
	protected override void OnCurrentCellMoved(GridCurrentCellMovedEventArgs e)
	{
		if(this.CurrentCell.MoveFromRowIndex != this.CurrentCell.MoveToRowIndex)
		{
			GridRangeInfo oldRange = GridRangeInfo.Row(this.CurrentCell.MoveFromRowIndex);
			if(Selections.Ranges.ActiveRange.Equals(oldRange))
			{
				Selections.Clear();
				Selections.SelectRange(GridRangeInfo.Row(this.CurrentCell.MoveToRowIndex), true);
			}
		}
		base.OnCurrentCellMoved (e);
	}
}
