Data Types Supported by ASPxHiddenField

• Jan 27, 2022

The ASPxHiddenField control can store values of non-string types.

List of Supported Types

All supported types can be divided into the following three categories:

• Elements (atomic values)

  System.String

  System.Guid

  System.Byte

  System.Int16

  System.Int32

  System.Int64

  System.Double

  System.Boolean

  System.Single

  System.Decimal

  System.Char

  System.DateTime

  System.Text.RegularExpressions.Regex

  System.DBNull

  Nullable<T> - All analogies are supported except for String, Regex, and DBNull (which cannot be Nullable because they are not structures).

• Lists

  Lists of value types, Regex and DBNull types are supported.

• Dictionaries

  All string-key dictionaries that implement the IDictionary interface are supported.

Note

ASPxHiddenField can store containers (lists, dictionaries) with values of the above types. These containers can have any nesting level.
For example, ASPxHiddenField can store a container that is a specifically designed business object with a set of key-value ({property name} - {property value}) pairs.

Note

ASPxHiddenField cannot be rendered if the control contains a key-value pair whose key is an empty string.

List of Types whose Information is not Passed to the Client

ASPxHiddenField does not serialize objects of the following types into JavaScript client-side objects:

System.Collections.Generic.Dictionary<string, object>

System.Object[]
