How to handle ContextMenuOpening

[Kasper Schou]

Hi Telerik,

I'm having trouble triggering the ContextMenuOpening event in order to handle the event and not show the context menu.

With standard WPF context menu I would handle the event on the control owning the context menu, but I can't seem to get this right with RadContextMenu control. Hope you can guide me on how to achieve this. I have a code block as below:

<telerik:RadCalendar Grid.Row="1" Margin="6,6,6,6" x:Name="calendar" IsTodayHighlighted="False" telerikControls:StyleManager.Theme="Vista"
            DayTemplateSelector="{StaticResource templateSelector}" Columns="4" Rows="3" ViewsHeaderVisibility="Visible" FirstDayOfWeek="Monday"
            HeaderVisibility="Visible" ContextMenuOpening="calendar_ContextMenuOpening">
    <telerik:RadContextMenu.ContextMenu>
        <telerik:RadContextMenu x:Name="cmCalendar" Opened="ContextMenuCalendar_Opened" telerikControls:StyleManager.Theme="Vista">
            <telerik:RadMenuItem x:Name="miHoliday" Header="{x:Static local:CentralCalendarWindowGlossary.miHoliday_Header}" Click="MenuItemHoliday_Click" IsCheckable="True" ToolTipService.ShowOnDisabled="True" ToolTipService.IsEnabled="{Binding Path=IsEnabled}" ToolTip="{DynamicResource toolTipDefault}" />
            <telerik:RadMenuItem x:Name="miNoDistribution" Header="{x:Static local:CentralCalendarWindowGlossary.miNoDistribution_Header}" IsCheckable="True" Click="MenuItemNoDistribution_Click" ToolTipService.ShowOnDisabled="True" ToolTipService.IsEnabled="{Binding Path=IsEnabled}" ToolTip="{DynamicResource toolTipDefault}" />
            <telerik:RadMenuItem IsSeparator="True" />
            <telerik:RadMenuItem x:Name="miSiteDistribution" Header="{x:Static local:CentralCalendarWindowGlossary.miSiteDistribution_Header}" Click="MenuItemSiteDistribution_Click" ToolTipService.ShowOnDisabled="True" ToolTipService.IsEnabled="{Binding Path=IsEnabled}" ToolTip="{DynamicResource toolTipDefault}">
                <telerik:RadMenuItem.Icon>
                    <Image Source="/AN.Planner.Administrator;component/Images/SiteDetailsViewSmall.ico" />
                </telerik:RadMenuItem.Icon>
            </telerik:RadMenuItem>
        </telerik:RadContextMenu>
    </telerik:RadContextMenu.ContextMenu>
</telerik:RadCalendar>

The event never invokes "calendar_ContextMenuOpening"

Thanks in advance,
Best regards

Hi Kasper,

Unfortunately, I was unable to reproduce the bug. I have made a short video in which you can see my attempt. Please feel free to correct me if I am doing something wrong.
Please try to reproduce it in a sample application and send it back to us in order to track down the source of the problem.

Looking forward to your reply.

Hi Konstantina,

Thank you for the swift reply and the video example.

It seems you are doing the same I do, so I guess I will try copy this code into a new sample at test it. Something else must be blocking my event..

I'll get back when I've done this test.

Thanks,

Hi,

I now found my problem and it was nothing with the code, but I apperently was not working on the latest build of your controls. I performed the Upgrade Wizard, and after that it worked fine.

Thank you and im sorry for the inconvenience due to this mistake..

Best regards,
