How can I update Grids by using timestamp property?

Solution

You can achieve this requirement using the following implementation:

Create an editable Grid:

Razor

@(Html.Kendo().Grid<Telerik.Examples.Mvc.Areas.GridTimestamp.Models.Product>()
    .Name("grid")
    .Columns(columns =>
    {
        columns.Bound(p => p.ProductID);
        columns.Bound(p => p.ProductName);
        columns.Bound(p => p.RowVersionString);
        columns.Command(command => command.Edit());
    })
    .DataSource(source =>
    {
        source.Ajax()
        .Model(model =>
        {
            model.Id(p => p.ProductID);
            model.Field(p => p.ProductID).Editable(false);
        })
        .Read("Read", "Home")
        .Update("Update", "Home");
    })
)

Define the timestamp Model property:

public class Product
{
    [Key]
    [DatabaseGenerated(System.ComponentModel.DataAnnotations.Schema.DatabaseGeneratedOption.Identity)]
    public int ProductID { get; set; }
    public string ProductName { get; set; }

    [Timestamp]
    public byte[] RowVersion { get; set; }

    [NotMapped]
    public string RowVersionString
    {
        get
        {
            if (this.RowVersion != null)
            {
                return Convert.ToBase64String(this.RowVersion);
            }

            return string.Empty;
        }
        set
        {
            if (string.IsNullOrEmpty(value))
            {
                this.RowVersion = null;
            }
            else
            {
                this.RowVersion = Convert.FromBase64String(value);
            }
        }
    }
}

Define the Update Action:

public ActionResult Update(Product product)
{
    if (ModelState.IsValid)
    {
        context.Products.Attach(product);
        context.Entry(product).State = EntityState.Modified;
        context.SaveChanges();
    }

    return Json(new[] { product }.ToDataSourceResult(new DataSourceRequest(), ModelState));
}
