Handling controls on a dialog in AX

Add the following code in the class declaration

    DialogField     dlgType;

    DialogField     dlgAccount;

    DialogField     dlgName;

    #DEFINE.dialogTypeFieldNo(800)

    #DEFINE.dialogTypeCtrlName("Fld800_1")

    #DEFINE.dialogAccountFieldNo(900)

    #DEFINE.dialogAccountCtrlName("Fld900_1")

To allow the dialog to raise dialog field events

Override the dialogPostRun method and add the following code below the super()

    dialog.dialogForm().formRun().controlMethodOverload(true);

    dialog.dialogForm().formRun().controlMethodOverloadObject(this);

To add the controls to dialog

     dlgType = new DialogField(dialog, typeid(SalesPurch),#dialogTypeFieldNo);

    dlgType.init(dialog);

    dlgType.label("Account Type");

    // assert if resulting field name was not set as expected as this must match the method which processes the event, e.g. fld800_1_validate

    Debug::assert(dlgType.fieldname() == #dialogTypeCtrlName);

    dlgAccount = new DialogField(dialog,typeid(CustAccount),#dialogAccountFieldNo);

    dialog.addCtrlDialogField(dlgAccount.name());

    dlgAccount.init(dialog);

    dlgAccount.label("Account");

    dlgAccount.value();

    // assert if resulting field name was not set as expected as this must match the method which processes the event, e.g. fld900_1_validate

    Debug::assert(dlgAccount.fieldname() == #dialogAccountCtrlName);

    dlgName = dialog.addField(typeId(Name));

    dlgName.allowEdit(false);

Create a new method to handle the modified event of the account type field.

/// <summary>

/// Handling modified event of Account Type Control

/// </summary>

private boolean fld800_1_modified()

{

    Object control;

    boolean valueWasModified;

    ;

    control = dialog.formRun().controlCallingMethod();

    valueWasModified = control.modified();

    if (valueWasModified)

    {

        dlgAccount.value('');

        dlgName.value('');

    }

    return valueWasModified;

}

Create a new method to handle the lookup event of account field on a dialog.

/// <summary>

/// Opens the account lookup based on the account type selected.

/// </summary>

private void fld900_1_lookup()

{

    FormControl formControl=new FormControl();

    LedgerJournalACType accountType;

    ;

    formControl = dlgAccount.control();

    if (dlgType.value() == SalesPurch::Sales)

    {

        CustTable::lookupCustomer(formControl);

    }

    else if (dlgType.value() == SalesPurch::Purch)

    {

        VendTable::lookupVendor(formControl);

    }

}

Create a new method to handle the modified event of account field.

// handle the modified event for the "Account" dialog field

private void fld900_1_modified()

{

    CustTable   custTable;

    VendTable   vendTable;

    Object      control;

    boolean     valueWasModified;

    ;

    control = dialog.formRun().controlCallingMethod();

    valueWasModified = control.modified();

    if(valueWasModified)

    {

        if(dlgAccount.value()!='')

        {

            if (dlgType.value() == SalesPurch::Sales)

            {

                custTable   =   CustTable::find(dlgAccount.value());

                dlgName.value(custTable.Name);

            }

            else if (dlgType.value() == SalesPurch::Purch)

            {

                vendTable   =   VendTable::find(dlgAccount.value());

                dlgName.value(vendTable.Name);

            }

        }

        else

        {

            dlgName.value('');

        }

    }

}
