How to get absolute row,col index under mouse point

[Keith Steinbeck]

How can I get the absolute row,col index of a grid cell under the mouse? The Grid.CellClicked event gives the "proper" absolute coords, but if you are using

Point pt = m_Grid.PointToClient(Cursor.Position);
int row, col;
m_Grid.ViewLayout.PointToClientRowCol(pt,out row, out col, false, GridCellSizeKind.ActualSize);

you get coords of the VISIBLE grid. This works fine if the whole grid fits on the screen, but if not things don''t work quite so well; for example if you are trying to map the coords of the cell to an underlying data structure.

So the question becomes: How can I get the absolute cell coords inside a non-MouseEvent-based method or handler, like ContextMenu.Popup?

Try using

grid.PointToRowCol(pt, out row, out col, -1); // where pt is in the grid coordinate system

Great! That seems to do what I need. I''m curious though; the docs for that function state:

Points that below the last visible row or right of the last column will be adjusted as defined in the fixOutOfRange parameter.
Use -1 if Empty should be returned.

The return type is bool, and I don''t think there is a Boolean.Empty. Is this an error in the docs, or am I misunderstanding how this applies?

It is the row and col returned values that are influenced by the fixOutOfRange value. A zero returns a ''closest'' existing row/col. A non-zero value will return -1''s for both values.
