How to hide New and Delete buttons in a form in Dynamics AX/ D365 F&O X++

Below is the simple code I have written in form init() method to hide new and delete button from the user interface.

    public void init()
    {
        this.form().design().showNewButton(0);
        this.form().design().showDeleteButton(0);
        super();

    }

or

[ExtensionOf(FormStr(InventBatch))]
public final class P_InventBatchForm_Extension
{
    void run()
    {
        next run();
        inventBatch_ds.allowCreate(false); // Disable System Defined NEW Button
      }

}

Let me know if you have any questions
