Form Control Event Handler Methods in Dynamics 365 for Operations (AX7)

For example, In Dynamics 365 for Operations (AX7) you can react to the OnClicked event by copying the event handler method for the event and pasting the method into a class.

Create new Class and paste below code in it for SalesEditLines EventHandlers

 /// <summary>
    ///
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    [FormControlEventHandler(formControlStr(SalesEditLines, OK), FormControlEventType::Clicked)]
    public static void OK_OnClicked(FormControl sender, FormControlEventArgs e)
    {
        Args args = new Args();
        FormCommandButtonControl  callerButton = sender as FormCommandButtonControl;  //Retrieves the button that we're reacting to
        FormRun form = callerButton.formRun(); //Gets the running SalesEditLines form

        //Get the salesId that was selected in the SalesEditLines form
        FormDataSource salesParmTable_ds = form.dataSource(formDataSourceStr(SalesEditLines, SalesParmTable)) as FormDataSource;
        SalesParmTable salesParmTable = salesParmTable_ds.cursor();


        SalesTable salesTable=salesParmTable.salesTable();

        if(salesTable.SalesStatus==SalesStatus::Invoiced)
        {
     
//Any Action

        }
    }
