isCOBOL Evolve : User Interface : Controls Reference : GRID : Properties : Column-Protection
Column-Protection
This property allows you to set or retrieve the protection setting of the column identified by the X property.
Valid values are:
0
The column is not protected at all. The user can access the cells and modify their value. This is the default setting.
1
The column is read-only. The user can move into any cell in the column, but cannot change its content.
2
The column is protected. Any access to the cells in that column is denied. If the user tries to move to a protected column with the keyboard, it is skipped and the cursor goes to the next valid column. If protected column is clicked, no action occurs.
