Any reason why this won't work? The error complains that the ContextMenu cannot be assigned to something of type Object.

Thanks,

<igDP:XamDataGrid.Resources>
                <Style TargetType="{x:Type igDP:LabelPresenter}"
                       x:Key="HeaderContextMenu">
                    <Setter Property="ContextMenu">
                        <Setter.Value>
                            <ContextMenu>
                                <ContextMenu.Items>
                                    <ComboBoxItem Content="Edit Layout" />
                                </ContextMenu.Items>
                            </ContextMenu>
                        </Setter.Value>
                    </Setter>
                </Style>
            </igDP:XamDataGrid.Resources>

thanks, however why does the combo box item looks a bit funny? I assume it has picked up some of my header styling (which actually was just taken from the generic theme pack). how can i override this? the following doesn't do anything..

<igDP:XamDataGrid.Resources>
                <ContextMenu x:Key="cm">
                    <ContextMenu.Resources>
                        <Style TargetType="{x:Type ComboBoxItem}"
                               BasedOn="{StaticResource {x:Type ComboBoxItem}}">

                        </Style>
                    </ContextMenu.Resources>
                    <ComboBoxItem Content="Edit Layout" />
                </ContextMenu>

                <Style TargetType="{x:Type igDP:LabelPresenter}" BasedOn="{StaticResource {x:Type igDP:LabelPresenter}}">
                    <Setter Property="ContextMenu" Value="{StaticResource cm}"/>
                </Style>

            </igDP:XamDataGrid.Resources>

Thanks

Hello,

It seems that the ContextMenu property cannot be assigned with a style's setter in this way. What you can use is :

                 <ContextMenu x:Key="cm">
                    <ComboBoxItem Content="Edit Layout" />
                </ContextMenu>
                <Style TargetType="{x:Type igDP:LabelPresenter}">
                    <Setter Property="ContextMenu" Value="{StaticResource cm}"/>
                </Style>
