Hello, 

Is there any way to realize something like that: 

<Style x:Key="{x:Type xcdg:CellEditor}" TargetType="{x:Type xcdg:CellEditor}">

<Setter Property="ActivationGestures">

<Setter.Value>

<xcdg:ActivationGestureCollection>

<xcdg:KeyActivationGesture SystemKey="Down" Modifiers="Alt"/>

<xcdg:KeyActivationGesture Key="Up" Modifiers="Alt"/>

<xcdg:KeyActivationGesture Key="F4"/>

<xcdg:KeyActivationGesture Key="Space"/>

</xcdg:ActivationGestureCollection>

</Setter.Value>

</Setter>

</Style>

I receive the following message:

Error 1 The Property Setter 'ActivationGestures' cannot be set because it does not have an accessible set accessor.

regards

genne
