To Get & Set Unbound Control Values from a Form Extension, perform action on Controls

Example::

[FormDataSourceEventHandler(formDataSourceStr(CustTable, CustTable), FormDataSourceEventType::Activated)]

public static void CustTable_OnActivated(FormDataSource sender, FormDataSourceEventArgs e)

{

    CustTable           custTable     = sender.cursor(); //selected record

    FormDataSource      custTable_ds  = sender.formRun().dataSource("CustTable"); //DataSource form CustTable

    FormRun             element       = sender.formRun(); //form element

    FormControl         myNewButton   = element.design(0).controlName("MyNewButton"); //New button on the form

    FormStringControl         strResult;

    FormRealControl realResult;

    FormIntControl         intResult;

    FormDateControl dateResult;

    FormComboBoxControl comboResult;

    //To Get DataSource Current Record of a Field

    custTable.AccountNum = XXX.valueStr();

    //Str

    strResult = element.design().control(element.controlId("strResult"));

    //Set

    strResult.text("this is what it should say");

    //Get

    strResult.valueStr();

    //Real

    realResult = element.design().control(element.controlId("realResult"));

    //Set

    realResult.realValue(50.05);

    //Get

    realResult.value();

    //Integer

    intResult = element.design().control(element.controlId("intResult"));

    //Set

    intResult.value(50);

    //Get

    intResult.value();

     //Date

     dateResult = element.design().control(element.controlId("dateResult"));

     //Set

     dateResult.dateValue(today());

     //Get

     dateResult.dateValue();

     //Date

     comboResult = element.design().control(element.controlId("comboResult"));

     //Set

     comboResult.selection(1);

     //Get

    comboResult.valueStr(); //Convert to Enum to Str

    myNewButton.enabled(false); //Here you do your code to enabled or disabled the button

}
