    Remote Data Binding
    In This Topic

    FlexGrid allows you to retrieve data directly using C1JSONRequest. This specifies remote data URLs that include the server, table and columns. The arrays returned are used as data sources for CollectionView objects.

    CollectionViewHelper is a static class that enables collections to have editing, filtering, grouping, and sorting services. This class also includes the following methods:

    The Bind property in FlexGrid is used to bind it to a collection by passing an action URL method to carry out a specific operation.

    This topic demonstrates how to retrieve data from an existing data source remotely. This is useful for developing data-intensive applications and scenarios for representing data as dashboards. Refer to Quick Start: Add data to FlexGrid for explanation of Local Model Binding.

    The following image shows how the FlexGrid appears after making the C1JSON Request to fetch data from the model, Sale.cs, which was added to the application in the QuickStart:

    The following code examples demonstrate how to bind FlexGrid to fetch data from remote datasource:

    In Code


    Copy Code
    public partial class FlexGridController : Controller
        public ActionResult Index()
            return View();
        public IActionResult Index_Bind([C1JsonRequest] CollectionViewRequest<Sale> requestData)
            return this.C1Json(CollectionViewHelper.Read(requestData, Sale.GetData(15)));


    Copy Code
    @using C1.Web.Mvc.Grid
        .Columns(columns =>
            columns.Add(column => column.Binding("ID").Visible(false));
            columns.Add(column => column.Binding("Start").Format("MMM d yy"));
            columns.Add(column => column.Binding("End").Format("HH:mm"));
            columns.Add(column => column.Binding("Country"));
            columns.Add(column => column.Binding("Product"));
            columns.Add(column => column.Binding("Amount").Format("c"));
            columns.Add(column => column.Binding("Discount").Format("p0"));
