Radio buttons in forms are an alternative for field selection menus. Radio buttons are combined in a radio button area and linked to a field. Instead of the field the form will display the radio button area with the radio buttons contained. When entering the area (i.e. the now invisible field in Mask-Edit state) the area will become active (gets a visible border) and the radio can activate a radio button. The corresponding text or parts of it are taken into the field when the record is stored. If a radio button area is linked to a field displayed in the list, DataView will automatically display a regular selection menu.
You link a button area with a field by entering the button area name in the Mask Data form, sub-list Field Assignment., menu field. Additionally you have to select the selection menu type B in the Menu Type field. Because the link is established using the mask-field relation, the field can get another radio button area if it is used in other masks.
Each button record assigned to a radio button area creates a radio button with corresponding text. The text is specified in the Text fields of the item master. Observe the following rules to make sure that the text is correctly taken into the radio button field:
The position of radio buttons are specified in the fields Row and Column of the menu-item relation. The origin of the positioning is the upper left corner of the field, with which the radio button area is linked. In the fields Length and Width of the item master you only define text length and width. The radio button itself is not effected and always keeps the size of 1 column x 1 row.
