Local data

To bind the Local Data to the Toolbar control, map the user-defined JSON data names with its appropriate data source field. You can bind data to Toolbar by mapping fields such as Id, SpriteCssClass, ImageUrl, group and TooltipText.

The following steps explain how you can bind local data to Toolbar Control.

In the View page, add Toolbar helper to configure Toolbar.

  • // Add this code in your CSHTML page and refer local data section for data source
    <ej-toolbar id="toolbar" dataSource="ViewBag.datasource">
        <e-toolbar-fields id="iconid" sprite-css-class="spriteCss">
  • C#
  • public class ToolbarLocalBinding
    	public string iconid { get; set; }
    	public string spriteCss { get; set; }
    public IActionResult Index()
    	List<ToolbarLocalBinding> t = new List<ToolbarLocalBinding>();
    	t.Add(new ToolbarLocalBinding { iconid = "1", spriteCss = "mailtools movetofolder" });
    	t.Add(new ToolbarLocalBinding { iconid = "2", spriteCss = "mailtools categorize" });
    	t.Add(new ToolbarLocalBinding { iconid = "3", spriteCss = "mailtools flag" });
    	t.Add(new ToolbarLocalBinding { iconid = "4", spriteCss = "mailtools forward" });
    	t.Add(new ToolbarLocalBinding { iconid = "5", spriteCss = "mailtools newmail" });
    	ViewBag.datasource = t;
    	return View();
  • CSS
  • <style type="text/css" class="cssStyles">
    	.e-tooltxt .mailtools {
            background-image: url('../Content/images/maild.png');
        .e-tooltxt .mailtools {
            display: block;
            background-image: url('../Content/images/maill.png');
            height: 24px;
            width: 24px;
            background-repeat: no-repeat;
        .e-tooltxt:hover .mailtools, .darktheme .cols-sample-area .e-tooltxt:hover .mailtools {
            background-image: url('../Content/images/mailh.png');
        .mailtools.movetofolder {
            background-position: -12px -40px;
        .mailtools.categorize {
            background-position: -14px -248px;
        .mailtools.flag {
            background-position: -13px -282px;
        .mailtools.forward {
            background-position: -14px -314px;
        .mailtools.newmail {
            background-position: -14px -348px;
        .frame {
            height: 280px;
            width: 695px;
            border-radius: none;
            margin-left: 0;
            margin-top: 40px;
            padding: 0;
        .control {
            margin: 120px 200px 0;

    Remote data

    You can bind Toolbar to Remote Data using DataManager and the query in fields is used to retrieve the data. DataManager supports the following types of data-binding: JSON, Web Services and OData. It uses two different classes; ej.DataManager for processing, and ej.Query for serving data. ej.DataManager communicates with data source and ej.Query generates data queries that are read by the DataManager.

    The following steps explain how you can bind remote data to Toolbar control.

    1. In the View page, add Toolbar helper to configure Toolbar.
  • <ej-toolbar id="toolbarOdata" width="300px" query="ej.Query().from('Orders').take(6)">
        <e-toolbar-fields text="CustomerID" />
        <e-datamanager url="//"></e-datamanager>
