Remarks
By default, the DetailsView control returns to the mode specified by the DefaultMode property. Use the KeepInInsertMode property to specify whether the DetailsView control should remain in insert mode after an insert operation. To keep the DetailsView control in insert mode, set this property to true.
Note
This property should be used when you want to want to override the default mode only occasionally. If the DetailsView control needs to remain in insert mode by default, set the DefaultMode property instead.
