UIHintAttribute UIHintAttribute UIHintAttribute UIHintAttribute Class

Definition

Specifies the template or user control that Dynamic Data uses to display a data field.

public ref class UIHintAttribute : Attribute
[System.AttributeUsage(System.AttributeTargets.Field | System.AttributeTargets.Property, AllowMultiple=true)]
[System.AttributeUsage(System.AttributeTargets.Property | System.AttributeTargets.Field, AllowMultiple=true)]
public class UIHintAttribute : Attribute
type UIHintAttribute = class
    inherit Attribute

Examples

The following example shows how to use the UIHintAttribute attribute to specify the name of a custom field template that will handle the display and editing of a data field.

For a complete example, see How to: Customize Data Field Display in the Data Model.

using System;
using System.Web.DynamicData;
using System.ComponentModel.DataAnnotations;

[MetadataType(typeof(ProductMetadata))]
public partial class Product 
{

}

public partial class ProductMetadata
{
    [UIHint("UnitsInStock")]
    [Range(100, 10000, 
    ErrorMessage = "Units in stock should be between {1} and {2}.")]
    public object UnitsInStock;

}
Imports System
Imports System.Web.DynamicData
Imports System.ComponentModel.DataAnnotations


<MetadataType(GetType(ProductMetadata))> _
Partial Public Class Product

End Class

Partial Public Class ProductMetadata
    <UIHint("UnitsInStock")> _
    <Range(100, 10000)> _
    Public UnitsInStock As Object
End Class

Remarks

MVC uses the UIHintAttribute class to associate a model with a data field. Dynamic Data uses the UIHintAttribute class to associate a user control with a data field. Dynamic Data uses the UIHint property to determine which user control to use in order to display a data field.
