AX- create Forms using classes

  • Cikk

Design AX Forms:

1. Using AOT. (right click AOT>Forms nodes and add a new form. You add controls under 'Design' sub node and tables under 'Data Source' subnode)

OR

2. Using X++ code to dynamically create and display a form.

 

X++ Dynamic Forms:  

1. FORM and FORMRUN classes can be used to create forms using code.

2. AOT > System Documentation > Classes > Form** classes - Look here for the list of all the Form Classes.

              Form Classes categories:

[1] FormBuild Classes are used to design a form in the code.

ex: FormBuildDataSource, FormBuildDesign, FormBuildGridControl, FormBuildButtonControl, FormBuildStringControl

[2] FormRun Classes are used to control the form elements during the run time.

ex: FormDataSource, FormDesign, FormTabControl, FormGridControl, FormButtonControl, FormStringControl etc.

 

FormBUILD classes to design a form

      1. Create a class with Main method.  see the example below

-Create Form Header,

-Add Data Source,

-Add elements to Design node. (Add TabControl > Add TabPageControls > Add Grid Button & String Control to the TabPage controls)

 

  Output before click:

                        

 

FormRUN class: to modify the forms on the fly.

                     1. In above example this piece of code will override the Form button control clicked method with a method (method1) defined in our example class (AAClass1).

                                 

 

                   2. Create a new method in Class 'AAClass1\method1'. - when button is clicked 'registerOverrideMethod' will redirect the call to method1.

- Get the handle of the button and find the parent of parent of the button (i.e. TabPage and then Tab control),

- Add new TabPage control, Add String Control to the new TabPage

 

                                                                                         

 

Output after click - when the button 'a' in the above example is clicked. A new Tab Page is created and new String control is added to this TabPage control displaying the first column of the data source.
