TipUse the scheduler's smart tag to generate a default context menu for appointments, time rulers or time cells in design-time, and customize it as required. Refer to the Create Context Menu topic for details.

Add a New Item
The OptionsContextMenu class provides options that allow you to customize context menus. Use the *ContextMenuActions property to access the target context menu's actions collection. Add an InsertAction to the retrieved collection to add a new item to the context menu. The following code sample inserts two new items to the appointment context menu.
| Xaml:MainWindow.xaml |
<dxsch:OptionsContextMenu.AppointmentContextMenuActions>
<dxb:InsertAction Index="-1">
<dxb:BarButtonItem Content="Recurrence"
Glyph="{dx:DXImage Image=Recurrence_32x32.png}"
Command="{Binding ElementName=schedulerCommands, Path=OpenRecurrenceWindowCommand}">
</dxb:BarButtonItem>
</dxb:InsertAction>
<dxb:InsertAction>
<dxb:BarCheckItem x:Name="allDayCheck"
Content="All-Day Appointment"
Glyph="{dx:DXImage Image=Check_16x16.png}"
CheckedChanged="allDayCheck_CheckedChanged"/>
</dxb:InsertAction>
</dxsch:OptionsContextMenu.AppointmentContextMenuActions>
|
As a result, the menu appears as follows.
Update an Existing Item
Obtain the context menu's action collection and add an UpdateAction to it to update any existing context menu item, as shown in the code sample below.
| Xaml:MainWindow.xaml |
<dxsch:OptionsContextMenu.TimeRulerContextMenuActions>
<dxb:UpdateAction ElementName="{x:Static Member=dxsch:DefaultBarItemNames.ContextMenu_Items_TimeRuler_Actions_NewAllDayEvent}"
PropertyName="IsVisible"
Value="False"/>
<dxb:UpdateAction ElementName="{x:Static Member=dxsch:DefaultBarItemNames.ContextMenu_Items_TimeRuler_Actions_NewRecurringEvent}"
PropertyName="IsVisible"
Value="False"/>
<dxb:UpdateAction ElementName="{x:Static Member=dxsch:DefaultBarItemNames.ContextMenu_Items_TimeRuler_Actions_NewAppointment}"
PropertyName="IsEnabled"
Value="False"/>
<dxb:UpdateAction ElementName="{x:Static Member=dxsch:DefaultBarItemNames.ContextMenu_Items_TimeRuler_Actions_NewRecurringAppointment}"
PropertyName="IsEnabled"
Value="False"/>
</dxsch:OptionsContextMenu.TimeRulerContextMenuActions>
|
The image shows the code execution result.
Remove the Item
Add a RemoveAction to the menu's action collection to delete any item from the target context menu. The code snippet shows how to delete an item from the appointment drop context menu.
| Xaml:MainWindow.xaml |
<dxsch:OptionsContextMenu.AppointmentDropContextMenuActions>
<dxb:RemoveAction ElementName="{x:Static Member=dxsch:DefaultBarItemNames.ContextMenu_Items_AppointmentDrop_Actions_CopyAppointmentsOnDrop}"/>
</dxsch:OptionsContextMenu.AppointmentDropContextMenuActions>
|
The resulting context menu is shown on the image below.
The OptionsContextMenu.*ContextMenu properties allow you to provide a custom context menu instead of the default one. The code sample below shows how to provide a custom cell pop-up menu shown in the image.
| Xaml:MainWindow.xaml |
<dxsch:OptionsContextMenu.CellContextMenu>
<dxb:PopupMenu>
<dxb:PopupMenu.Items>
<dxb:BarButtonItem Content="Add Broadcast..."
Glyph="{dx:DXImage Image=Appointment_16x16.png}"
Command="{Binding ElementName=schedulerCommands, Path=ShowNewAppointmentWindowCommand}"/>
<dxb:BarButtonItem Content="Add News Block..."
Glyph="{dx:DXImage Image=RecurringAppointment_16x16.png}"
Command="{Binding ElementName=schedulerCommands, Path=ShowNewRecurringAppointmentWindowCommand}"/>
</dxb:PopupMenu.Items>
</dxb:PopupMenu>
</dxsch:OptionsContextMenu.CellContextMenu>
