Load the content as partial view to Tab in ASP.NET MVC Tabs control

18 Oct 2021 / 1 minute to read

Since Tab is a Navigation control, it doesn’t have support to load any content directly or using any DataAdaptor. But it is provided with the items support. So to load the content as partial view, you would need to make use of the AJAX or EJ2 Datamanager as described in our How-To section help document.

In the below demo, we have explained on how to create the Tab items dynamically and then to load the other Syncfusion controls in it from partial views.

<div id='GridOrder1'></div>

@Html.EJS().Tab("MainTab").Created("Created").Selecting("Selecting").Render()

<script>
   function Created() {
        var TabObj = document.getElementById("MainTab").ej2_instances[0];
        var ajax = new ej.base.Ajax('@Url.Action("PartialView1", "Home")', 'GET', true);
        ajax.send().then();
        ajax.onSuccess = function (data) {
            TabObj.addTab([{ header: { 'text': 'Grid1' }, content: "#GridOrder1" }], 0);
            TabObj.addTab([{ header: { 'text': 'Grid2' }, content: "#GridOrder2" }], 1);
            $("#GridOrder1").html(data);
        }
    }
    function Selecting(e) {
        if (e.selectingIndex != 0){
            var ajax = new ej.base.Ajax('@Url.Action("PartialView2", "Home")', 'GET', true);
            ajax.send().then();
            ajax.onSuccess = function (data) {
                $("#GridOrder2").html(data);
            }
        }
    }
</script>


//Code in the PartialView1

        })
        .Columns(col =>
        {
            col.Field("OrderID").HeaderText("Order ID").Width("120").TextAlign(Syncfusion.EJ2.Grids.TextAlign.Right).Add();
            col.Field("CustomerID").HeaderText("Customer ID").Width("160").Add();

            col.Field("ShipCountry").HeaderText("Ship Country").Width("150").Add();
        }).AllowPaging().PageSettings(page => page.PageCount(3))

        })
        .Columns(col =>
        {

            col.Field("UnitsInStock").HeaderText("QuantityPerUnit").Width("120").TextAlign(Syncfusion.EJ2.Grids.TextAlign.Right).Add();
