Public Property KeyActionTab As KeyActionEnum
public KeyActionEnum KeyActionTab {get; set;}
Remarks
By default, the grid will ignore the TAB key and it will be handled by the form, moving the focus to the next control in the tab order. If you set the C1.Win.C1FlexGrid.C1FlexGridBase.KeyActionTab property to a value other than C1.Win.C1FlexGrid.KeyActionEnum.None, the grid will trap the TAB key and use it for navigating cells.
