Pass the parameter from one form to another in Dynamic AX

 Create two forms with Name FormA & FormB.

 FormA with 1 stringedit and 1 button & FormB with 1 StringEdit.

 Below code is override in clicked method() of button.

void clicked()

{

    // Args class is usually used in Axapta for passing parameters between forms

    Args            args;

    FormRun         formRun;

    ;

    args = new args();  

    // Our values which we want to pass to FormB

    // If we want pass just simple string we can use 'parm' method of 'Args' class

    args.parm( AccountNum.text() );

    // Run FormB

    args.name( formstr( FormB ) );

    formRun = classFactory.formRunClass( Args );

    formRun.init();

    formrun.run();

    formrun.wait();

    super();

}

 Now override init() method in FormB.

public void init()

{

    str             anyStringValueFromCaller;

    ;

    super();

    // Check for passed arguments

    if( element.args() )

    {

        // get string parameter

        anyStringValueFromCaller = element.args().parm();

        SelectedAccountNum.text(anyStringValueFromCaller);

    }

}
