Description

This is the generic calendar control.

Attributes

name = SqlName . A page level unique name identifying a control.

annotation. A human readable comment.

initial-enable = CalculateableValue . Determines whether a control is initially visible. True by default. Could be data-bound to an SQL expression.

enabled = CalculateableValue . Determines whether a control is visible. True by default. Could be data-bound to an SQL expression.

instantiate = CalculateableValue . Determines whether a control instantiate its children. It is true by default. It could be data-bound to an SQL expression. Unlike most of calcucateable attributes, the value of this attribute for a control is calcluated before calling 'on-init' event handler of the control; other values are calculated before calling 'before-data-bind' event handler.

control-udt = SqlName . At run time every control is represented as an instance of some user-defined type (UDT). VSPX compiles selects the UDT to use depending on name of the XML element that represents the control and maybe some of its attributes. In some specific cases the application developer may instruct VSPX compiler to use some other UDT, e.g. an application-specific UDT that is derived from the preset one. If specified, the value of 'control-udt' attribute should be equal to the name of the desired target UDT.

xsd-stub-xhtml. This attribute is for internal use only. It has no effect if added to the source VSPX file.

width. Visible width of the control when it is displayed in WYSIWYG tools when the source VSPX text is edited. The value of this attribute will not be used when the resulting HTML is rendered.

height. Visible width of the control when it is displayed in WYSIWYG tools when the source VSPX text is edited. The value of this attribute will not be used when the resulting HTML is rendered.

initial-date = CalculateableValue . Expression which returns a date for setting initially the current date of the calendar.

debug-srcfile. URI of the source document where the tag comes from.

debug-srcline. Line number in the source document where the tag comes from.

debug-log. This defines what sort of data are saved to the debugging log.

Declaration of type vspx_calendar

create type vspx_calendar under vspx_control as
(
  cal_date date,
  cal_meta any,
  cal_selected datetime,
  cal_current_row vspx_row_template
) temporary self as ref
method vc_get_date_array () returns any,
overriding method vc_view_state (stream any, n int) returns any,
overriding method vc_set_view_state (e vspx_event) returns any,
constructor method vspx_calendar (name varchar, parent vspx_control)
