To handle single cells as well as covered cells, try code like this to see if it serves your needs.

 Rect GetCellRect(int rowIndex, int columnIndex, GridControlBase grid)
        {
            GridRangeInfo range = GridRangeInfo.Cell(rowIndex, columnIndex);
            if (grid.Model.CoveredCells.Find(rowIndex, columnIndex, out range))
            {
                range = range.ExpandRange(1, 1, grid.Model.RowCount, grid.Model.ColumnCount);
            }

            double width = 0;
            for(int i = columnIndex; i <= range.Right; ++i)
                width += grid.Model.ColumnWidths[i];

            double height = 0;
            for (int i = rowIndex; i <= range.Bottom; ++i)
                height += grid.Model.RowHeights[i];

            double yLocation = grid.ScrollRows.GetVisibleLineAtLineIndex(rowIndex).Origin;
            double xLocation = grid.ScrollColumns.GetVisibleLineAtLineIndex(columnIndex).Origin;
            return new Rect(xLocation, yLocation, width, height);
        }

Hi,

Thanks for the code, it serve my needs, even if the calculation of the rectangle of covered cell doesn't work.

The coveredcell code worked for me when I tried it, but I always passed it the top-left cell when requesting the covered cell rect. If you are not passing it the top-left cell, tweak the code as follows:

double width = 0;
for(int i = range.Left; i <= range.Right; ++i)
width += grid.Model.ColumnWidths[i];

double height = 0;
for (int i = range.Top; i <= range.Bottom; ++i)
height += grid.Model.RowHeights[i];

Thanks Clay,

It works.
But i'll stick with the less than perfect code. It suit more
my purpose ;-)
