Create dialog form using X++

Dynamics 365 gives the capability to create dialog form.We can however also create a dialog form through code dynamically at runtime.

1. Create a class called DEMODialog extending RunBase



 public class DEMODialog extends RunBase  
 {  
 }  



2. Add global variables that will be the parameters that will be accepted in our dialog



 public class DEMODialog extends RunBase  
 {  
   DialogField       dialogSalesId;  
   SalesId salesId;  
   FormDataSource     formDataSource;  
 }  





3. Create dialog method to give the dialog caption, add the field, add field label. Look at the image at the last to understand the below code.



 Object dialog()  
   {  
     Dialog dialog = super();  
     ;  
     dialog.caption("Dialog caption");  
     dialog.addTabPage("Tab page");  
     DialogGroup dialogGroup = dialog.addGroup("dialog group");  
     // Add a field for a name to the dialog. This will populate the field with  
     // any value that happens to be saved in name from previous uses of the  
     // dialog.  
     dialogSalesId = dialog.addField(extendedTypeStr(SalesId));  
     dialogSalesId.label("Salesid");  
     return dialog;  
   } 



4. Override the validate method to validate if a value is provided in the field(if needed)



 boolean validate (Object _calledFrom = null)  
   {  
     boolean isValid;  
     isValid = super(_calledFrom);  
     // Perform any validation nessecary.  
     if (!dialogSalesId.value())  
     {  
       isValid = checkFailed("Validation failed")) && isValid;  
     }  
     return isValid;  
   }  



5. Create the main method to execute the dialog box.



 public static void main (Args _args)  
   {  
     DEMODialog demoDialog= new DEMODialog();  
     // Display the dialog. This only returns true if the the user clicks "Ok" and validation passes.  
     if (demoDialog.prompt())  
     {  
        //Logic when Ok is clicked goes here  
     }  



6. Create an action menu item with the object type as class and object as DEMODialog.
7. Open the menu item to trigger the dialog.

The final dialog that opens up :
