How tu use dialog

Dialog is a base class in Dynamics AX. Use the dialog class to create simple dialog forms at run time. Here is an example:

Dialog      dialog;

DialogField field;

;

 

dialog = new Dialog("My Dialog"); 

field  = dialog.addField(typeId(EmplId)); // add EmplId field

 

dialog.run(); // show

 

if (dialog.closedOK())

{

    info(field.value());

}

[edit] Dynamic dialog

Initiated by this newsgroup posting I've written a class that for dynamic dialogs. You provide a list with types, and the dialog will contain all necessary fields. Use the method parmFieldList() to get the field values.

/**

 * Use this class to create a dialog with dynamic content.

 */

class CustomDialog extends Dialog

{

  List fieldList; /* list of dynamically create dialog fields */

 

  /** 

   * The dialog will contain fields for all types in the typeList 

   * Field description is taken per default from the extended datatype

   */

  void new(List    typeList,

           Caption _caption = '',

           Object  _caller  = null,

           str     _parmstr = '',

           Form    _form    = new Form(formStr(Dialog))

           )

  {

    ListEnumerator enum;

    ;

 

    if(typeList == null) 

      error("List of types must not be null");

 

    super(_caption,_caller,_parmStr,_form);

 

    fieldList = new List(Types::Class);

    enum      = typeList.getEnumerator();

 

    while(enum.moveNext())

    {

      fieldList.addEnd(this.addField(enum.current()));

    }

  }

  

  /**

   * Use this method to get the values entered in the dialog

   * @return Reference to the fieldList if instantiated.

   */

  public List parmFieldList()

  {

    return fieldList;

  }

}

The class is easy to use

static void testDynamicDialog(Args _args)

{

  CustomDialog   diag;

  List           types = new List(Types::Integer); // typeId is an integer

  List           fields;

  ListEnumerator enum;

  DialogField    field;

  ;

 

  // the dialog shall contain fields for the following types

  types.addEnd(typeId(EmplId));

  types.addEnd(typeId(Itemid));

  types.addEnd(typeId(ProdId));

  types.addEnd(typeId(CustAccount));

 

  // crate and show

  diag = new CustomDialog(types,"Dynamic Dialog");

  diag.run();

 

  // show values in the Infolog

  fields = diag.parmFieldList();

  enum   = fields.getEnumerator();

 

  while(enum.moveNext())

  {

    field = enum.current();

    info(field.value());

  }

}
