14 Nov 20224 minutes to read

For the Tab control, the tab items can be rendered in the controller and can be returned as ViewBag to bind as items. You can also map the content to other contents using the mapping id in controller to return as ViewBag. Refer to the below sample, which takes chart, grid, calender as its content through viewBag content id mapped in view.

CSHTML
Viewbag.cs
@using Syncfusion.EJ2.Navigations;

<div class="info">
    Tab content loaded from ViewBag
</div>

<div id="Content1" style="display: none">
    <ejs-chart id="ej2chart" width="100%" height="100%">
        <e-series-collection>
            <e-series type="@Syncfusion.EJ2.Charts.ChartSeriesType.Line" xName="x" yName="yValue" dataSource="@ViewBag.datasource" name="Gold" width="2">
                <e-series-marker visible="true"/>
            </e-series>
        </e-series-collection>
        <e-chart-primaryxaxis interval="1" valueType="@Syncfusion.EJ2.Charts.ValueType.Category" title="Olympic Medal Counts - RIO" />

<ejs-tab id="ej2Tab" items="@ViewBag.items"></ejs-tab>
public ActionResult Index()
{
    List<TabItem> tabItems = new List<TabItem>();
    tabItems.Add(new TabItem { Header = new TabHeader { Text = "Chart" }, Content = "#Content1" });
    tabItems.Add(new TabItem { Header = new TabHeader { Text = "Grid" }, Content = "#Content2" });
    tabItems.Add(new TabItem { Header = new TabHeader { Text = "Calender" }, Content = "#Content3" });
    ViewBag.items = tabItems;
    //chart data
    List<ColumnChartData> chartData = new List<ColumnChartData>
    {
        new ColumnChartData { x= "USA", yValue= 46 },
        new ColumnChartData { x= "GBR", yValue= 27 },
        new ColumnChartData { x= "CHN", yValue= 26 }
    };
    ViewBag.dataSource = chartData;
    return View();
}

public class ColumnChartData
{
    public string x;
