I have a Car class that I'm trying to display in an MVC 3 view using the WebGrid helper. Below are the Car and it's metadata class.
Car class:
[MetadataType(typeof(CarMetadata))]
public partial class Car
{
// car implementation
}
Car metadata class:
public class CarMetadata
{
[DisplayName("Car Name")]
[StringLength(100, ErrorMessageResourceType = typeof(ValidationText), ErrorMessageResourceName="CarNameDescriptionLength")]
[Required]
public string CarName { get; set; }
}
View contents:
@model List<Car>
...
var grid = new WebGrid(Model, canPage: true, rowsPerPage: 10);
grid.Pager(WebGridPagerModes.NextPrevious);
@grid.GetHtml(
htmlAttributes: new { id = "grid" },
columns: grid.Columns(
grid.Column("CarName", ?????)
));
GOAL: I'd like to figure out how to use the DisplayName data annotation as the column header text in the WebGrid (?????). Does anyone know how this is accomplished?
Thanks in advance!
Ugly as hell but it could work:
grid.Column(
"CarName",
ModelMetadata.FromLambdaExpression(
car => car.CarName,
new ViewDataDictionary<Car>(new Car())
).DisplayName
)
The problem is that the WebGrid helper is entirely based on dynamic data, absolutely no strong typing and that's one of the reasons why I hate it. The WebMatrix team at Microsoft must be real fans of the C# 4.0 dynamic feature as their entire API takes only weakly typed objects :-)
MvcContrib Grid is much better.
