Disallow Editing Specified Cells in a Datagrid

Ray.


Could you generally set the "allowEditing" (which is global for the whole DG) to false, and open it only when certain cells are (or are not) clicked on?

Ray,

It exists different possibilities depending the conditions you need
for locking a cell.

A possible solution is to trap in the datagrid group script, the
EditCellOfIndex message sent when one is double clicking on a cell.

Here is an example for locking a cell if it contains the value "Locked cell":

on EditCellOfIndex pTheColumn, pTheIndex
  if GetDataOfIndex(pTheIndex, pTheColumn) is "Locked cell" then exit
EditCellOfIndex

  pass EditCellOfIndex
end EditCellOfIndex
