Syntax

'Declaration
Public Property Type As String

public string Type { get; set; }

public:
property String^ Type {
    String^ get ();
    void set (String^ value);
}

/** @property */

Property Value

A String, between 1 and 255 characters in length, that specifies the data type of the field.

Remarks

You must set the field type for all notification fields.

Field types must conform to SQL Server data types. The following data types are supported by Notification Services:

bigint

float

real

tinyint

binary

int

smalldatetime

uniqueidentifier

bit

money

smallint

varbinary

char

nchar

smallmoney

varchar

datetime

nvarchar

sql_variant

xml

decimal

numeric

 

 

The text, ntext, and image data types are not supported because they cannot be used as values for parameters and variables in stored procedures. In addition, the timestamp data type is not supported. For more information about SQL Server data types, see Data Types (Database Engine).

If using the xml data type with the XSLT content formatter, the content formatter might attempt to transform the XML data. To preserve the XML markup, set the content formatter's DisableEscaping argument to false.

If you modify a field type, updating the application deletes and re-creates the notification class to which it corresponds. This includes dropping and re-creating the SQL Server tables and indexes used by this notification class. Any data existing in the original notification class tables is permanently deleted.

Example

The following examples show how to define a notification field that has a data type of float, and then add it to the collection of notification fields for a notification class:

// Define a Price field and add it at position 1 in the collection
NotificationField notificationPrice = 
    new NotificationField(flightNotifications, "Price");
notificationPrice.Type = "float";
flightNotifications.NotificationFields.Add(notificationPrice, 1);

' Define a Price field and add it at position 1 
' in the collection.
Dim notificationPrice As NotificationField = _
    New NotificationField(flightNotifications, "Price")
notificationPrice.Type = "float"
flightNotifications.NotificationFields.Add( _
    notificationPrice, 1)

Thread Safety

Any public static (Shared in Microsoft Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
