This property directly controls whether delete operations are allowed on the data source level. By configuring it to "No," you ensure that regardless of how users interact with the form, they will be restricted from executing delete actions on customer records stored in the CustTable.

This method is particularly advantageous because it enforces the restriction at the data source level, which is the foundational layer where the data resides. As such, users will not find any options to delete records, regardless of their access level or the customizations present in the user interface.

Other options, while potentially limiting deletion in some ways, do not guarantee the same level of security and prevention. For instance, removing the Delete command button from the form could simply hide the option but does not prevent deletion through other means, such as keyboard shortcuts or scripts. Setting the View Edit Mode property to View would restrict editing capabilities, but it doesn't specifically address deletion. Implementing an OnDeleted event handler could potentially allow for more complex logic to prevent deletion, but it requires additional coding and doesn’t inherently stop the deletion action unless properly managed. In contrast, adjusting the
