    Hi,
    I am trying to subscribe to a Blazor Menu ItemClicked event but I can’t figure out what the syntax in the mark up to connect it up with the handler.
    I have this in the markup:
    <Menu DataSource=”@MenuItems” ItemClicked=”MenuClicked” id=”menu”>
    and this in the code section
    public void MenuClicked(object sender, MenuItemClickedEventArgs args)
    {}
    How connect the ItemClicked event to the MenuClicked handler?

    Hi ScottP,
    Thanks for trying out our Blazor components.
    In order to subscribe to the Menu event, you can use the following syntax:

    @page "/menu"
    <Example Name="Menu">
    	<Menu OnItemClick="OnItemClick" id="menu">
    		<MenuItemsGroup>
    			File
    			<MenuItem Shortcut="Ctrl+N">New</MenuItem>
    			<MenuItem Shortcut="Ctrl+0">Open</MenuItem>
    			<MenuItemsGroup>
    				Open Containing Folder
    				<MenuItem>Explorer</MenuItem>
    				<MenuItem>cmd</MenuItem>
    			</MenuItemsGroup>
    			<MenuItem Shortcut="Ctrl+S" disabled>Save</MenuItem>
    			<MenuItem Shortcut="Ctrl+Alt+S" separator>Save As...</MenuItem>
    			<MenuItem Shortcut="Alt+F4">Exit</MenuItem>
    		</MenuItemsGroup>
    		<MenuItemsGroup>
    			Edit
    			<MenuItem Shortcut="Ctrl+Z">Undo</MenuItem>
    			<MenuItem Shortcut="Ctrl+Y" separator>Redo</MenuItem>
    			<MenuItem Shortcut="Ctrl+X">Cut</MenuItem>
    			<MenuItem Shortcut="Ctrl+C">Copy</MenuItem>
    			<MenuItem Shortcut="Ctrl+V" disabled>Paste</MenuItem>
    		</MenuItemsGroup>
    		<MenuItemsGroup DropDownHeight=300>
    			Encoding
    			<MenuItem>Encode in ANSI</MenuItem>
    			<MenuItem>Encode in UTF-8</MenuItem>
    			<MenuItem>Encode in UTF-8-BOM</MenuItem>
    			<MenuItem>Encode in UTCS-2 BE BOM</MenuItem>
    			<MenuItem>Encode in UTCS-2 LE BOM</MenuItem>
    			<MenuItemsGroup separator>
    				Character sets
    				<MenuItemsGroup>
    					Cyrillic
    					<MenuItem>ISO 8859-5</MenuItem>
    					<MenuItem>KOI8-R</MenuItem>
    					<MenuItem>KOI8-U</MenuItem>
    					<MenuItem>Windows-1251</MenuItem>
    				</MenuItemsGroup>
    				<MenuItemsGroup>
    					Chinese
    					<MenuItem>Big5 (Traditional)</MenuItem>
    					<MenuItem>GB2312 (Simplified)</MenuItem>
    				</MenuItemsGroup>
    				<MenuItemsGroup>
    					Western European
    					<MenuItem>ISO 8859-1</MenuItem>
    					<MenuItem>ISO 8859-15</MenuItem>
    					<MenuItem>OEM 850</MenuItem>
    					<MenuItem>Windows-1252</MenuItem>
    				</MenuItemsGroup>
    			</MenuItemsGroup>
    			<MenuItem>Convert to ANSI</MenuItem>
    			<MenuItem>Convert to UTF-8</MenuItem>
    			<MenuItem>Convert to UTF-8-BOM</MenuItem>
    			<MenuItem>Convert to UTCS-2 BE BOM</MenuItem>
    			<MenuItem>Convert to UTCS-2 LE BOM</MenuItem>
    		</MenuItemsGroup>
    	</Menu>
    </Example>
    @code {
        void OnItemClick(Event eventObj)
        {
            MenuItemClickEventDetail detail = eventObj["Detail"];
            Console.WriteLine(detail.Label);
        }
    }

    Hope this helps.

    Thanks for the reply.
    Your response was for:
    <table class=”table”>
    <tbody>
    <tr>
    <td>OnItemClick</td>
    <td>EventCallback<Event></td>
    <td>This event is triggered when a menu item is clicked.</td>
    <td>dynamic item, string label, dynamic value</td>
    </tr>
    </tbody>
    </table>
    but I was asking about:
    <table class=”table”>
    <tbody>
    <tr>
    <td>ItemClicked</td>
    <td>event MenuItemClickedEventHandler</td>
    <td>This event is triggered when a menu item is clicked.</td>
    <td>MenuItemClickedEventArgs</td>
    </tr>
    </tbody>
    </table>
    Can you please show an example for this handler?
    Thanks.

    Hi Scott,
    It is not possible to subscribe to ItemClicked event using Razor syntax, because it is not defined as a component Parameter and it cannot be as it is “event” type. It is possible to subscribe to the event using the syntax I sent you. ItemClicked way to subscribe to events is useful only when you want to add multiple event handlers.
    For Example:

    @page "/menu"
    <Example Name="Menu">
    <Menu OnReady="OnReady" OnItemClick="OnItemClick" id="menu">
    <MenuItemsGroup>
    File
    <MenuItem Shortcut="Ctrl+N">New</MenuItem>
    <MenuItem Shortcut="Ctrl+0">Open</MenuItem>
    <MenuItemsGroup>
    Open Containing Folder
    <MenuItem>Explorer</MenuItem>
    <MenuItem>cmd</MenuItem>
    </MenuItemsGroup>
    <MenuItem Shortcut="Ctrl+S" disabled>Save</MenuItem>
    <MenuItem Shortcut="Ctrl+Alt+S" separator>Save As...</MenuItem>
    <MenuItem Shortcut="Alt+F4">Exit</MenuItem>
    </MenuItemsGroup>
    <MenuItemsGroup>
    Edit
    <MenuItem Shortcut="Ctrl+Z">Undo</MenuItem>
    <MenuItem Shortcut="Ctrl+Y" separator>Redo</MenuItem>
    <MenuItem Shortcut="Ctrl+X">Cut</MenuItem>
    <MenuItem Shortcut="Ctrl+C">Copy</MenuItem>
    <MenuItem Shortcut="Ctrl+V" disabled>Paste</MenuItem>
    </MenuItemsGroup>
    <MenuItemsGroup DropDownHeight=300>
    Encoding
    <MenuItem>Encode in ANSI</MenuItem>
    <MenuItem>Encode in UTF-8</MenuItem>
    <MenuItem>Encode in UTF-8-BOM</MenuItem>
    <MenuItem>Encode in UTCS-2 BE BOM</MenuItem>
    <MenuItem>Encode in UTCS-2 LE BOM</MenuItem>
    <MenuItemsGroup separator>
    Character sets
    <MenuItemsGroup>
    Cyrillic
    <MenuItem>ISO 8859-5</MenuItem>
    <MenuItem>KOI8-R</MenuItem>
    <MenuItem>KOI8-U</MenuItem>
    <MenuItem>Windows-1251</MenuItem>
    </MenuItemsGroup>
    <MenuItemsGroup>
    Chinese
    <MenuItem>Big5 (Traditional)</MenuItem>
    <MenuItem>GB2312 (Simplified)</MenuItem>

    <MenuItem>ISO 8859-1</MenuItem>
    <MenuItem>ISO 8859-15</MenuItem>
    <MenuItem>OEM 850</MenuItem>
    <MenuItem>Windows-1252</MenuItem>

    <MenuItem>Convert to UTCS-2 BE BOM</MenuItem>
    <MenuItem>Convert to UTCS-2 LE BOM</MenuItem>
    </MenuItemsGroup>
    </Menu>
    </Example>
    @code {
    void OnReady(Menu menu)
    {
    menu.ItemClicked += delegate(object sender, MenuItemClickedEventArgs args)
    {
    Console.WriteLine(args.Label);
    };
    }
    void OnItemClick(Event eventObj)
    {
    MenuItemClickEventDetail detail = eventObj["Detail"];
    Console.WriteLine(detail.Label);
    }
    }
