    </ContextMenuSettings>
    <AppointmentSettings Id="Id" Subject="Subject" AllDay="AllDay" StartTime="StartTime" EndTime="EndTime" Description="Description" Recurrence="Recurrence" RecurrenceRule="RecurrenceRule"/>  
</ej:Schedule>

<asp:SqlDataSource ID="SqlData" runat="server" ConnectionString="<%$ ConnectionStrings:ScheduleConnectionString %>"
         SelectCommand="SELECT * FROM [DefaultSchedule]"></asp:SqlDataSource>

NOTE

In agenda view, only the appointment menu items shows up in the context menu options. For default menu items, the Id must be defined the same as mentioned in the above code example – as we have processed the menus based on this Id within our source.

Apart from the default available options, it is also possible to add custom menu options to the context-menu of both the appointment and cell collection.

The following code example depicts how to add the custom menu items to the appointment and cell collection of the context menu settings.

HTML

<!--Container for ejScheduler widget-->
<ej:Schedule ClientIDMode="Static" runat="server" ID="Schedule1" DataSourceID="SqlData" Width="100%" Height="525px" CurrentDate="5/2/2014">
    <ContextMenuSettings Enable="true">
        <MenuItems>
            <AppointmentCollection>
                <ej:Appointment Id="open" Text="Open Appointment" />
                <ej:Appointment Id="delete" Text="Delete Appointment" />
                <ej:Appointment Id="option1" Text="User Option 1" />
            </AppointmentCollection>
            <CellsCollection>
                <ej:Cells Id="celloption1" Text="Custom Option 1" />
            </CellsCollection>
        </MenuItems>
    </ContextMenuSettings>
    <AppointmentSettings Id="Id" Subject="Subject" AllDay="AllDay" StartTime="StartTime" EndTime="EndTime" Description="Description" Recurrence="Recurrence" RecurrenceRule="RecurrenceRule"/>  
</ej:Schedule>

 <asp:SqlDataSource ID="SqlData" runat="server" ConnectionString="<%$ ConnectionStrings:ScheduleConnectionString %>"
            SelectCommand="SELECT * FROM [DefaultSchedule]"></asp:SqlDataSource>

NOTE

The Id given for the custom menu items must be unique in both the appointment and cell collection.

To define specific actions for a click made on the custom menu items, the client-side event menuItemClick can be used as depicted in the below code example.

HTML

<!--Container for ejScheduler widget-->
<ej:Schedule ClientIDMode="Static" runat="server" ID="Schedule1" DataSourceID="SqlData" Width="100%" Height="525px" CurrentDate="5/2/2014" MenuItemClick="onMenuItemClick">
    <ContextMenuSettings Enable="true">
        <MenuItems>
            <AppointmentCollection>
                <ej:Appointment Id="open" Text="Open Appointment" />
                <ej:Appointment Id="delete" Text="Delete Appointment" />
                <ej:Appointment Id="option1" Text="User Option 1" />
            </AppointmentCollection>
        </MenuItems>
    </ContextMenuSettings>
    <AppointmentSettings Id="Id" Subject="Subject" AllDay="AllDay" StartTime="StartTime" EndTime="EndTime" Description="Description" Recurrence="Recurrence" RecurrenceRule="RecurrenceRule"/>  
</ej:Schedule>

<asp:SqlDataSource ID="SqlData" runat="server" ConnectionString="<%$ ConnectionStrings:ScheduleConnectionString %>"
            SelectCommand="SELECT * FROM [DefaultSchedule]"></asp:SqlDataSource>
           
<asp:Content ID="ScriptContent" runat="server" ContentPlaceHolderID="ScriptSection">
    <script type="text/javascript">
        function onMenuItemClick(args) {
            //args.events contains information of the clicked menu item.
            if (args.events.ID == "option1")
                alert("Custom menu clicked");
        }
    </script>
</asp:Content>

Also, it is possible to predict the target on which the right click is made, either on the cells or appointments with the use of the event beforeContextMenuOpen. The below code example shows how to block the display of context menu, when right clicked on the cells by setting args.cancel as true.

<ej:Schedule ClientIDMode="Static" runat="server" ID="Schedule1" DataSourceID="SqlData" Width="100%" Height="525px" CurrentDate="5/2/2014" BeforeContextMenuOpen="onBeforeContextMenuOpen">
    <ContextMenuSettings Enable="true">
        <MenuItems>
            <AppointmentCollection>
                <ej:Appointment Id="open" Text="Open Appointment" />
                <ej:Appointment Id="delete" Text="Delete Appointment" />
                <ej:Appointment Id="option1" Text="User Option 1" />
            </AppointmentCollection>
        </MenuItems>
    </ContextMenuSettings>
    <AppointmentSettings Id="Id" Subject="Subject" AllDay="AllDay" StartTime="StartTime" EndTime="EndTime" Description="Description" Recurrence="Recurrence" RecurrenceRule="RecurrenceRule"/>  
</ej:Schedule>

<asp:SqlDataSource ID="SqlData" runat="server" ConnectionString="<%$ ConnectionStrings:ScheduleConnectionString %>"
            SelectCommand="SELECT * FROM [DefaultSchedule]"></asp:SqlDataSource>
            
<asp:Content ID="ScriptContent" runat="server" ContentPlaceHolderID="ScriptSection">
    <script type="text/javascript">
        function onBeforeContextMenuOpen(args) {
            //args.events.target – target information to depict either cell/appointment
            if ($(args.events.target).hasClass("e-workcells") || $(args.events.target).hasClass("e-monthcells"))
                args.cancel = true;
        }
    </script>
</asp:Content>

Adding Categorize Option

To include the default categorize option within the context menu, it is necessary to enable the CategorizeSettings property as shown in the below code example.

HTML

<!--Container for ejScheduler widget-->
<ej:Schedule ClientIDMode="Static" runat="server" ID="Schedule1" DataSourceID="SqlData" Width="100%" Height="525px" CurrentDate="5/2/2014">
    <ContextMenuSettings Enable="true">
        <MenuItems>
            <AppointmentCollection>
                <ej:Appointment Id="open" Text="Open Appointment" />
                <ej:Appointment Id="delete" Text="Delete Appointment" />
                <ej:Appointment Id="categorize" Text="Categorize" />
            </AppointmentCollection>
        </MenuItems>
    </ContextMenuSettings>
    <CategorizeSettings Enable="true"></CategorizeSettings>
    <AppointmentSettings Id="Id" Subject="Subject" AllDay="AllDay" StartTime="StartTime" EndTime="EndTime" Description="Description" Recurrence="Recurrence" RecurrenceRule="RecurrenceRule"/>  
</ej:Schedule>

<asp:SqlDataSource ID="SqlData" runat="server" ConnectionString="<%$ ConnectionStrings:ScheduleConnectionString %>"
            SelectCommand="SELECT * FROM [DefaultSchedule]"></asp:SqlDataSource>

NOTE

The Categorize option must be added only to the Appointment collection, which displays on right clicking the appointments.
