I would like to dynamically create a set of context menu options based upon some properties.
Currently, I am creating a context menu as a DynamicResource with the visibility of the menu options bound to the properties, however, it seems that the DynamicResource is created only once, at runtime. Is this true? What I would like to do is have the menu generated each time, which will take into account the property changes on the data object.
Please see the following XAML snippet:
<Border DockPanel.Dock="Right" Margin="4,4,4,4" BorderBrush="Gray" BorderThickness="1" CornerRadius="3" >
<igDP:XamDataGrid Height="Auto" Width="Auto" Style="{DynamicResource DefaultInfragisticsGridStyle}" Name="axeDataGrid" ActiveRecord="{Binding Path=SelectedItem, Mode=TwoWay}" DataSource="{Binding Path=Axes}" ContextMenuOpening="ContextMenuOpeningHandler">
<igDP:XamDataGrid.Resources>
<Style TargetType="{x:Type igDP:DataRecordPresenter}" BasedOn="{x:Static Themes:DataPresenterAero.DataRecordPresenter}"/>
<ContextMenu x:Key="RecordContextMenu">
<ContextMenu.Resources>
<BooleanToVisibilityConverter x:Key="booleanToVisibilityConverter"/>
</ContextMenu.Resources>
<MenuItem Header="Cancel Axe"
Command="{Binding RelativeSource={RelativeSource FindAncestor,
AncestorType={x:Type igDP:XamDataGrid}},
Path=DataContext.CancelAxe}"
Visibility="{Binding RelativeSource={RelativeSource FindAncestor,
AncestorType={x:Type igDP:XamDataGrid}},
Path=DataContext.IsCancelAxeAllowed, Converter={StaticResource booleanToVisibilityConverter}, Mode=OneWay}"/>
<MenuItem Header="Create RFQ"
Command="{Binding RelativeSource={RelativeSource FindAncestor,
AncestorType={x:Type igDP:XamDataGrid}},
Path=DataContext.CreateRFQ}"
Visibility="{Binding RelativeSource={RelativeSource FindAncestor,
AncestorType={x:Type igDP:XamDataGrid}},
Path=DataContext.IsCreateRfqAllowed, Converter={StaticResource booleanToVisibilityConverter}, Mode=OneWay}"/>
</ContextMenu>
<Style TargetType="{x:Type igDP:DataRecordCellArea}">
<Setter Property="ContextMenu" Value="{DynamicResource RecordContextMenu}" />
</Style>
