(1)
The left and the width of the amount column can be determined using objToClient(ColumnObject, 2) and objToClient(ColumnObject, 3)
Be aware that objToClient returns form coordinates - so you will need to get the objToClient() of the parent of the grid (form, page, container) and adjust the column's obtToClient to the coordinates of the parent of the grid

You can use bindEvent ( with nFlags = 1: call delegate after event code ) to bind to
- column.Moved event
- column Resize event

You may also have to bind to column.Visible

To test is what happens when the grid is scrolled horizontally. Does that trigger the Moved event ? Also, the column may not be visible any more

And if you start working with panels - that may be interesting since the column can appear twice !

> footer

Nothing comes to mind
