ListBox.ReadOnly
Read and write.
Type:
Boolean.
Indicates whether the list box is editable. If the value of this property is
True, then you can only view the list box.
Thick client.
As opposed to
Enabled property, if ReadOnly property is set to
True, then you cannot edit the list box; however, this does not affect other operations with the box. For example, you can select string presentation of the list box contents and copy it to the clipboard.
