i have an issue similar to this post but using styles. http://forums.infragistics.com/forums/t/32165.aspx

i have a grid with a bunch of cols in it but only 3 are for editing. lets call them a, b, c.  i have logic that states you can edit Either a OR b & c.  if a is disable and b & c are active, once you edit b or c it disables the other, so if you enter a 7 in cell c be would not be able to be editing any more.

i have this working for the most part. here is the style i am using to do this

<Style x:Key="myCanNotEditCell"
                   BasedOn="{StaticResource myCellChild}"
                   TargetType="igGrid:CellControl">
                <Setter Property="Background"
                        Value="Gray" />
                <Setter Property="IsEnabled"
                        Value="False" />               
            </Style>

in the dgPO_CellControlAttached AND dgPO_CellExitedEditMode  i have logic that controls the setup but checking number values such as x > 0, etc.

My problem that i seem to be stuck on is when i tab from cell a to b (IsOnCellActiveEditingEnabled="true") it goes into Edit Mode even though the style above is applied

if i remove the IsOnCellActiveEditingEnabled it works fine

editing setting for ref

<igGrid:ColumnLayout.EditingSettings>
<igGrid:EditingSettingsOverride AllowEditing="Cell"
IsMouseActionEditingEnabled="SingleClick"
IsOnCellActiveEditingEnabled="true" />
</igGrid:ColumnLayout.EditingSettings>
