iwf_frm_cns

Creates the defined link form for displaying elements of linked tables.


Parameters:

link [form]

Link
Name of the link. You can only specify links you already defined.

Form
Name of the form displaying the elements of linked tables. You can only specify forms containing elements of linked data base tables. It makes no difference whether these are master-, type-, or relation forms. You can only specify a form together with the link. If you do not specify a form, DataView will display the default form you created for the linked data base tables during model definition. For you can link master-, type-, or relation tables, DataView displays the corresponding default form on the screen.


Usage as:

On_Select userexit in each menu/button-area or On_Event userexit in each state of the user interface.


Explanation:

If you invoke the userexit in the Select menu of a list, i.e. at the selected record, DataView will fill only the fields of the form with the current data if you defined either no userexit or the wdh_upd_lis userexit at the pre_mask-trigger of the form. Each other Pre_Mask userexit prevents that the data of the selected record are displayed. You will then have to start a new query using the standard functions refresh or query to fill the form with data. However, the relation to the selected, calling record will be lost.
