This example shows how to use client edit template with Telerik Grid for ASP.NET MVC. There are a few built-in templates for Date, Currency and Number editing which can be found in the EditorTemplates folder in the installation.
Decorate your model with metadata attributes to specify its data type, UI hint (name of the ASCX to use) etc:
public class EditableOrder
{
[ReadOnly(true)]
public int OrderID { get; set; }
// EditorTemplates/ClientEmployee.ascx will be used as editor template.
[UIHint("ClientEmployee"), Required]
public string Employee { get; set; }
// EditorTemplates/Date.ascx will be used as display template.
[DataType(DataType.Date), Required]
public DateTime OrderDate { get; set; }
[DataType(DataType.Currency), Required]
public decimal Freight { get; set; }
}
