Asked On December 11, 2019 02:41 PM UTC

Is there a chance to set tooltip (html attribute title) for MenuItem generated in c# code.
I am using EjsMenu control, my menu control is docked inside sidebar as shown in sample.
I am trying to set tooltip for icons inside menu, so when is menu minimized user can on hover over menu item get tooltip for what is menu, without clicking on it , or toggling sidebar

Here is snippets of code I am using to build menu

<EjsMenu CssClass="dock-menu" Items="@MainMenuItems" Orientation="@Verorientation">
                                </EjsMenu>

@code {
    public Orientation Verorientation = Orientation.Vertical;
 public List<MenuItem> MainMenuItems = new List<MenuItem>{

        new MenuItem {
            Text = "Meni", IconCss = "icon-comment-inv-alt2 icon",
        },

        new MenuItem
        {
            Text="Pokupi podateke", IconCss="icon-comment-inv-alt2 icon" ,Url="/fetchdata"
        },

        new MenuItem {
            Text = "Overview", IconCss = "icon-user icon",
                Items = new List<MenuItem> {
                    new MenuItem{ Text = "All Data" },
                    new MenuItem{ Text = "Category2" },
                    new MenuItem{ Text = "Category3" }
                }
            },


}

}

Hi Admir Hodžic, 
Thank you for contacting Syncfusion support.   
  
We have checked your reported query and you can achieve this by using Menu template. We have created the sample for your requirement, in that we have added the tooltip on menu items. Please refer the below sample link,

Thank you a lot on your effort and support.
Your sample is working, but unfortunately looks like when templating items is selected callback event can't figure anymore which item fired event.
Without templates MenuSelect callback event receiving MenuEventArgs which contain info about Text and and other MenuItemModel property.
Can we construct MenuSelect callback when using templates to receive any reference form TemplatedModel so we can do selected logic in code behind.

My EjsMenu subscribe to MenuSelect event

 <EjsMenu CssClass="dock-menu" ModelType="@MenuTemplate" Fields="@MenuFields" Orientation="@Verorientation" Items="@MainMenuItems">
                                <MenuTemplates>
                                    <Template Context="templateContex">
                                        @{
                                            var MenuItems = (templateContex as MenuTemplateModel);
                                            if (MenuItems.Icon != null)
                                            {
                                                <span class="e-menu-icon @MenuItems.Icon" title="@MenuItems.Value"></span>
                                            }
                                            if (!string.IsNullOrEmpty(MenuItems.Link))
                                            {
                                                <a rel='nofollow' href="@MenuItems.Link">@MenuItems.Value</a>
                                            }
                                            else
                                            {
                                                @MenuItems.Value
                                            }
                                        }
                                    </Template>
                                </MenuTemplates>
                                <MenuEvents  ItemSelected="MenuSelect">
                                    
                                </MenuEvents>

in @code i get fired event
private void MenuSelect(MenuEventArgs args)
    {
        if (args.Item.Text == "Meni")
            this.sidebar.Toggle();
    }
But  args.Item does not preserve Text , Or ID or anything that I could use to route my action in code behind.
Thanks in advance

Hi Admir Hodžic, 
 
Good day to you. 
 
We have checked your reported query and we suggest you to add model type as “@typeof(MenuItemModel)” to get the menu item text in “ItemSelected” event.

Hello Syncfusion Team,

your attached sample works, but when i extent the sample with a menu referenz  and extend the function "onItemSelected":

public void onItemSelected(MenuEventArgs args)
    {
        string itemText = args.Item.Text;
        Toggle();
        menu.Refresh();
    }

the menuitems are not displayed:


I have a second question:
How can i design the tooltip?

Thanks in advance

Hi Arunkumar,

i use the Oqtane framework (www.oqtane.org), it has a custom siterouter. On the startpage (Default.razor) the menu is build. My mistake was, that i have build the menuItems in the function "OnParameterSetAsync". Now, i build the menuItems in the function "OnInitializedAsync" and it works as expected.

Thank you again for your help.

Please think about question query 2: How can i design the tooltip?

Hi Arunkumar,

basically your example works. But if the sidebar has a width of e.g. 50px, the tooltip is cut off. I tried using z index and fixed width for the tooltip but it doesn't work. Can you help me here?

Hi Arunkumar,

yes, i want display the tooltip at the right side of the menu icon.

Please change the style for the tooltip in your sample https://www.syncfusion.com/downloads/support/forum/149848/ze/BlazorApp-1026886092
with the following:

  .tooltip {
        top: 20px;
        color: black;
        opacity: 0;
        position: absolute;
        font-size: 14px;
        left: 20px;
        background-color: crimson;
    }

When the sidebar is docked, you can't see the tooltip.

Thank's in advance

Good day to you. 
 
You can use below css style to achieve your requirement. Please refer the code snippets and sample link below

.sidebar-menu,

Hello Madhan,

thank you for your sample, it works fine.
Unfortunately my requirements have changed in this way:
Basically, the sidebar should be completely hidden (docksize = 0px) and should only be shown using the Hamburger button. If the window is smaller than 600px, then the sidebar should only have a width of 50 px and the menu should only show the icon with the tooltip. If the window is larger than 600 px, the menu should be displayed with an icon and text and without a tooltip. You can see the functionality in the attached example. Unfortunately it does not work, because the menu text is always displayed.



Thanks in advance

Hi Reinhard, 
 
Good day to you. 
 
You can override the menu styles to achieve your requirement. Please refer the below code snippets. 
 
@@media (max-width: 600px) { 
     
    .sidebar-menu .e-menu-wrapper ul.e-menu { 
        min-width: 48px; 
    } 
 
    .sidebar-menu .e-menu-wrapper ul.e-menu .e-menu-item { 
        font-size: 0; 
    } 
    .sidebar-menu .e-menu-wrapper,
