Properties

Label

Control: Gets or sets the label associated with this control through its containing SAL form.

NamedProperties

SalNamedProperties: Gets this window's SAL named-property collection.

Text

String: Gets or sets the calendar text while suppressing invalid-format exceptions. (Default: "")

Methods

BringWindowToTop()

Brings this control to the front, or activates it when it is a top-level or MDI form.

Returns: SalBoolean. True if the translated control exists and is not disposed; otherwise, false.

CenterWindow()

Centers this window within its parent, owner, or available screen area.

Returns: SalBoolean. True if the centering operation is accepted; false for an unavailable control, design mode, or unavailable screen bounds.

ClearCursor(nType)

Restores the default cursor for the requested role.

Parameter	Type	Description
nType	SalNumber	The cursor role: Sys.CURSOR_Window, Sys.CURSOR_DragDrop, or Sys.CURSOR_DisableDrop.

Returns: SalBoolean. True if the operation is accepted by the SAL window implementation; otherwise, false.

Returns: SalBoolean. True if the operation is accepted by the SAL window implementation; otherwise, false.

DisableWindowAndLabel()

Disables input to this control and disables its associated label.

Marks this SAL window disposed before releasing the base control resources.

Parameter	Type	Description
disposing	Boolean	True to release managed resources; false for finalization cleanup.

EnableWindow()

Enables input to this control, or enables editing for a table column.

Returns: SalBoolean. True if the operation is accepted by the SAL window implementation; otherwise, false.

For text-box controls, this operation also clears the read-only setting.
