Definition

Namespace:

System.ComponentModel.DataAnnotations

Assembly:

System.ComponentModel.Annotations.dll

Source:

RequiredAttribute.cs

Gets or sets a value that indicates whether an empty string is allowed.

public:
 property bool AllowEmptyStrings { bool get(); void set(bool value); };

public bool AllowEmptyStrings { get; set; }

member this.AllowEmptyStrings : bool with get, set

Public Property AllowEmptyStrings As Boolean

Property Value

Boolean

true if an empty string is allowed; otherwise, false. The default value is false.

Remarks

When you set AllowEmptyStrings to true for a data field, Dynamic Data does not perform validation and transforms the empty string to a null value. This value is then passed to the database.

If the database does not allow null values, it raises an error. To avoid this error, you must also set the ConvertEmptyStringToNull to false.
