Type:
UsualThe value held in the control, in whatever data type the control holds.
Remarks
The value held in the control, in whatever data type the control holds. Control:Value is thus of the usual data type. For example, in a regular edit control, the value can be the string "Jones" or the number 14683. In a check box, Control:Value can be TRUE or FALSE. In a list box or combo box, the Control:Value is generally one of the return values (unless the control is bound to a field where the actual contents is not one of the allowable choices). In a radio button group, Control:Value holds the group value (specified in the Window Editor) of the radio button that is currently selected; if none is selected, Control:Value is set to NIL.
The data type of the control's Value is determined by its field specification; in turn, controls linked to a data server inherit the field specification—and hence data type—from the field of the server. When the control is made data-aware, by setting its name to the name of a field in the server attached to the data window, Control:Value is able to automatically read from and write to this field.
Tip |
---|
Value may not always be consistent with the state of the control, as indicated to the end-user. For example, if the data value for the field is not one of the allowed choices for a list box or combo box return value, or among the group value settings for the radio buttons in a radio button group, the control will be in a "no-match" situation. In this case the control will revert to its initial unselected state. |
