Hugo,

suggestion - rather test for loObject.BaseClass - Columns may be subclassed



>If you have AllowCellSelection = .f. for the grid, you can use code similar to the following to determine which column has been clicked, dblclicked

>local laObjects(1), loObject, lcType

>Amouseobj(laObjects)
>
>loObject			= laObjects[1]
>
>if Type('loObject.Parent') = 'O'
>	loObject			= loObject.Parent
>endif
>
>if Type([loObject.Class]) = [C] and loObject.Class = 'Column'
>	do case
>		case loObject.ColumnOrder = 2
>		case loObject.ColumnOrder = 4
