Thanks. I might well use that approach, depending on how much progress I make.

Currently I am implementing a solution whereby the grid is read only but when the user double clicks on a cell, it becomes editable. So instead of plain text, they now see a combo box, or a tick box, or a numeric value editor. Double click elsewhere, and the cell becomes read only. This works well with the Microsoft WPF DataGrid though the memory usage is still rather high. The non editable cell control is a Label.

I am also looking at the WPF Table View control on CodePlex. As yet I cannot find out how to make the current cell active when double clicked on, but the memory usage and speed are better. Clearly I can easily pop up a dialog to edit a cell, or a row as you suggest since I can trap the mouse double click.

From searching around it does seem that the performance of grids is a widespread problem.
