Item Configuration in ASP.NET MVC Toolbar control

10 Aug 20237 minutes to read

The Toolbar can be rendered by defining an array of items. Items can be constructed with the following built-in command types or item template.

Button

Button is the default command type, and it can be rendered by using the text property. Properties of the button command type:

Property Description
text The text to be displayed for button.
id The ID of the button to be rendered. If the ID is not given, auto ID is generated.
prefixIcon Defines the class used to specify an icon for the button. The icon is positioned before the text if text is available or the icon alone button is rendered.
suffixIcon Defines the class used to specify an icon for the button. The icon is positioned after the text if text is available. If both prefixIcon and suffixIcon are specified, only prefixIcon is considered.
width Used to set the width of the button.

Separator

The Separator type adds a vertical separation between the Toolbar’s single/multiple commands.

@using Syncfusion.EJ2.Navigations;

@(Html.EJS().Toolbar("defaultToolbar")
    .Width("300px")
    .Items(new List<ToolbarItem> {
        new ToolbarItem { Text = "Cut" },
        new ToolbarItem { Text = "Copy" },
        new ToolbarItem { Type = ItemType.Separator },
        new ToolbarItem { Text = "Paste" },
        new ToolbarItem { Type = ItemType.Separator },
        new ToolbarItem { Text = "Undo" },
        new ToolbarItem { Text = "Redo" }
    })
    .Render()
)
public ActionResult Index()
{
    return View();
}

NOTE

If Separator is added as the first or the last item, it will not be visible.

Input

The Input type is only applicable for adding template elements when the template property is defined as an object. Input type creates an input element internally that acts as the container for Syncfusion input based components.

Note: Set toolbar item type property value as Input only for Input components.

NumericTextBox

  • The NumericTextBox component can be included by importing the NumericTextBox module from ej2-inputs.

  • Initialize the NumericTextBox in template property, where the Toolbar item type is set as Input.

  • Related NumericTextBox component properties can also be configured as given below.

<ejs-numerictextbox format="n2"></ejs-numerictextbox>

  • The DropDownList component can be included by importing the DropDownList module from ej2-dropdowns.

  • Initialize the DropDownList in template property, where the Toolbar item type is set as Input.

  • Related DropDownList component properties can also be configured as given below.

<ejs-dropdownlist width="100"></ejs-dropdownlist>

RadioButton

  • The RadioButton component can be included by importing the RadioButton module from ej2-buttons.

  • Initialize the RadioButton in template property, where the Toolbar item type is set as Input.

  • Related RadioButton component properties can also be configured as given below.

<ejs-radiobutton label="Option 1" name="default"></ejs-radiobutton>

Output be like the below.

Toolbar Control with item configuration

Enabling tab key navigation in Toolbar

The tabIndex property of a Toolbar item is used to enable tab key navigation for the item. By default, the user can switch between items using the arrow keys, but the tabIndex property allows you to switch between items using the Tab and Shift+Tab keys as well.

To use the tabIndex property, you need to set it for each Toolbar item that you want to enable tab key navigation. The tabIndex property should be set to a positive integer value. A value of 0 or a negative value will disable tab key navigation for the item.

For example, to enable tab key navigation for two Toolbar items, you can use the following code:

@using Syncfusion.EJ2.Navigations;

<ejs-toolbar id="defaultToolbar">
    <e-toolbar-items>
        <e-toolbar-item text="Item 1" tabIndex = "1"></e-toolbar-item>
        <e-toolbar-item text="Item 2" tabIndex = "2"></e-toolbar-item>       
    </e-toolbar-items>
</ejs-toolbar>

With the above code, the user can switch between the two Toolbar items using the Tab and Shift+Tab keys, in addition to using the arrow keys. The items will be navigated in the order specified by the tabIndex values.

If you set the tabIndex value to 0 for all Toolbar items, tab key navigation will be based on the element order rather than the tabIndex values. For example:

@using Syncfusion.EJ2.Navigations;

<ejs-toolbar id="defaultToolbar">
    <e-toolbar-items>
        <e-toolbar-item text="Item 1" tabIndex = "0"></e-toolbar-item>
        <e-toolbar-item text="Item 2" tabIndex = "0"></e-toolbar-item>       
    </e-toolbar-items>
</ejs-toolbar>

In this case, the user can switch between the two Toolbar items using the Tab and Shift+Tab keys, and the items will be navigated in the order in which they appear in the DOM.

Example:

Here is an example of how you can use the tabIndex property to enable tab key navigation for a Toolbar component:

@using Syncfusion.EJ2.Navigations;

@(Html.EJS().Toolbar("defaultToolbar")
    .Width("300px")
    .Items(new List<ToolbarItem> {
        new ToolbarItem { Text = "Cut", TabIndex = 0 },
        new ToolbarItem { Text = "Copy", TabIndex = 0 },
        new ToolbarItem { Type = ItemType.Separator },
        new ToolbarItem { Text = "Paste", TabIndex = 0 },
        new ToolbarItem { Type = ItemType.Separator },
        new ToolbarItem { Text = "Undo", TabIndex = 0 },
        new ToolbarItem { Text = "Redo", TabIndex = 0 }
    })
    .Render()
)
public ActionResult Index()
{
    return View();
}

With the above code, the user can switch between the Toolbar items using the Tab and Shift+Tab keys, and the items will be navigated based on the element order.
