I have created a quite a few apps now that use a grid for data entry purposes and I am fairly pleased with them.

However it took a long time to get the desired effect so I have decided to use grids mainly for selecting items which are then edited using a form. I often use mutiple grids on a form so I have to get this right.

Now I have to choose the neatest way of launching the editing form.

I could have a button showing on the current row but that will use up an entire column just for that button. (however this is my favourite idea)

I could have the button outside the grid but the label on it would have to be bigger to make it clear that it was a grid item that the button applied to (and I end up with yet another button using up space on the main form).

A button for adding items will also have to go somewhere outside the grid or be assigned to a function key (this is a pity).

What is the neatest solution to this problem you have seen?
