Property Value

Type	Description
Type	A Type object, specifying the type declarations.

Remarks

The Parameter.Type property determines which values a parameter can accept. The corresponding value editors are created automatically for the following standard parameter types:

• String
• Date

• Number

  • 16-bit integer
  • 32-bit integer
  • 64-bit integer
  • floating point
  • double-precision floating point
  • decimal
• Boolean
• GUID (Globally Unique Identifier)

In the Print Preview, these editors are displayed in the Parameters panel.

The following image illustrates the standard editors for parameter values in a WinForms application.

To learn how to implement value editors for parameters of custom types (such as enumerations or XPCollection objects), see Requesting and Passing Report Parameter Values.
