Create simple Dialog using x++ in Ax 2012

   

                           Create A Simple Dialog

 

A dialog in Microsoft Dynamics AX is a simple form with a standardized layout, created by using the Dialog system class. It’s a way to present users with a simple input form, they are commonly used for small tasks, it should NOT be used to create complex forms. It should not open a secondary window that requires user interaction. All user interaction should be carried out within the dialog.

1. Open the AOT, and create a new class with the following code, its important ro extend RunBase because the RunBase framework uses the Dialog framework to prompt a user for data input. It uses the SysLastValue framework to persist usage data and the Operation Progress framework to show operation progress:

class CustCreateDialog extends RunBase {     DialogField fieldAccount;     DialogFIeld fieldName;     CustTable   custTable;     CustAccount custAccount; }

2. Override the method Dialog, this method will be used to give “form” to our Dialog:

protected Object Dialog() {     Dialog dialog;     ;     dialog = super();     // Set a title for dialog     dialog.caption( 'Simple Dialog');     // Add a new field to Dialog     fieldAccount = dialog.addField( extendedTypeStr(CustVendAC), 'Customer account' );     return dialog; }

3. Override the method getFromDialog, the code below will be used to retrieve the Dialog field values:

public boolean getFromDialog() {     // Retrieve values from Dialog     custAccount = fieldAccount.value();     return super(); }

4. Override the method run, use it to process whatever you want to. On my example I will use it to show the customer account information on infolog.

public void run() {     // Set Dialog field value to find CustTable     custTable = CustTable::find(custAccount);     if (custTable)     {         // Shows retrieved information         info( strFmt('%1 -- %2' , custTable.AccountNum, custTable.name()));     }     else     {         error( 'Customer Account not found!');     } }

5. Create a new main method to execute your class.

public static void main(Args _args) {     CustCreateDialog custCreate = new CustCreateDialog();     // Prompt the dialog, if user clicks in OK it returns true     if (custCreate.prompt())     {         custCreate.run();     } }

6. Execute your class, check results.
