State Persistence

Essential JS 2 has support for persisting component’s state across page refreshes or navigation. To enable this feature, set EnablePersistence property as true to the required component. This will store the component’s state in browser’s localStorage object on page unload event. For example, we have enabled persistence to grid component in the following code.

razor
@Html.EJS().Grid("check").DataSource(dataManger =>
   {
       dataManger.Url("http://services.odata.org/V4/Northwind/Northwind.svc/Products").CrossDomain(true).Adaptor("ODataV4Adaptor");
   }).Columns(col =>
        {
            col.Field("ProductID").HeaderText("Product ID").Width("120").TextAlign(Syncfusion.EJ2.Grids.TextAlign.Right).Add();
            col.Field("ProductName").HeaderText("Product Name").Width("150").Add();
            col.Field("UnitPrice").HeaderText("Supplier ID").Width("130").TextAlign(Syncfusion.EJ2.Grids.TextAlign.Right).Add();
            col.Field("UnitsInStock").HeaderText("QuantityPerUnit").Width("120").TextAlign(Syncfusion.EJ2.Grids.TextAlign.Right).Add();
            col.Field("Discontinued").HeaderText("Discontinued").Width("140").TextAlign(Syncfusion.EJ2.Grids.TextAlign.Center).Type("boolean").DisplayAsCheckBox(true).Add();
        })
        .EnablePersistence()
        .AllowPaging()
        .PageSettings(page=>page.PageCount(5))
        .Render()
