You can put the RadListView programmatically in insert mode using its ShowInsertItem method. As for the edit mode you will need to determine which ListView items you want to put in edit mode and then add them to the EditIndexes or EditItems collection of the control. Have in mind that you will need to call Rebind after each of those operations to take effect.
