By default every Sub Grid in Flex has the delete option available to delete an item as shown below in the pop up action box. Note that you must have the March 2019 update for this new feature.
From the main header of the Sub Grid the Delete icon will appear when items are selected as shown below.
In order to remove the Delete option from both of the above locations you now have two options:
- Remove the ability to delete items from all Sub Grids in Flex.
- Remove the ability to delete items from individual Sub Grids in Flex.
Remove Ability to Delete from All Sub Grids
Add a Setting called “SubGridAllowDelete” and give it value of “false”. This means that without this Setting the default is “true” which is the current behavior.
Remove Ability to Delete from Individual Sub Grids
In each Sub Grid’s properties there is now a configuration option to enable/disable deleting from that particular Sub Grid. Note that the “Allow” and “NotAllowed” options will override the Advanced Setting mentioned above.
Note: this configuration can be found under the “Flex Behavior” section.
