Hi,

I have a contextmenu in the header of a gridview, then inside the menuitem there's a checkbox wherein when selected it will call the command but it's not firing. I'm not sure if I have to include the AncestorLevel or use PlacementTarget.

VIEW

<telerik:GridViewDataColumn.Header>

<ToggleButton HorizontalAlignment="Left" IsChecked="{Binding IsOpen, ElementName=radContextMenuLink, Mode=TwoWay}">

<telerik:RadContextMenu.ContextMenu>

<telerik:RadContextMenu x:Name="radContextMenuLink" Placement="Bottom">

<telerik:RadMenuItem>

<telerik:RadMenuItem.Icon>

<Image Source="/Merchandise_Link;component/Images/link-icon.png" Stretch="Uniform" />

</telerik:RadMenuItem.Icon>

<telerik:RadMenuItem.HeaderTemplate>

<DataTemplate>

<CheckBox Name="chkHasLink" Command=

"{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=telerik:RadGridView}, Path=DataContext.HasLinkChangedCommand, Mode=TwoWay}"

CommandParameter="{Binding IsChecked, ElementName=chkHasLink}" />

</DataTemplate>

</telerik:RadMenuItem.HeaderTemplate>

</telerik:RadMenuItem>

<telerik:RadMenuItem>

<telerik:RadMenuItem.Icon>

<Image Source="/Merchandise_Link;component/Images/link-break-icon.png" Stretch="Uniform" />

</telerik:RadMenuItem.Icon>

<telerik:RadMenuItem.HeaderTemplate>

<DataTemplate>

<CheckBox Name="chkNoLink" Command=

"{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=telerik:RadGridView}, Path=DataContext.HasLinkChangedCommand}"

CommandParameter="{Binding IsChecked, ElementName=chkNoLink}" />

</DataTemplate>

</telerik:RadMenuItem.HeaderTemplate>

</telerik:RadMenuItem>

</telerik:RadContextMenu>

</telerik:RadContextMenu.ContextMenu>

</ToggleButton>

</telerik:GridViewDataColumn.Header>

ViewModel

HasLinkChangedCommand = New DelegateCommand(Of Object)(AddressOf subHasLinkChanged)

Private Sub subHasLinkChanged(ByVal objLink As Object)

'do something here

End Sub

Thanks,
Cielo
