The simplest solution is using File::getFileFromUser().

If you want something more sophisticated, you can use File upload control directly, which can be used in dialogs as well. Use Find references to find examples in the standard application (such as ERFileImportUIBuilder class).

In addition to what Martin said, check this link and see if it can help as it talks about uploading a file:

Please elaborate your problem - it's not clear what you mean by "i am not getting datasource on form run". Also, don't forget that we don't know your code, because you didn't tell us anything about it.

If dtProrpetyHeader is null, it means that form doesn't contain such a data source. Are you sure that you have the typo (Prorperty instead of Property) in the data source name? You can find these problems faster if you don't make the mistake of hard-coding objects names as strings. Instead, use methods like formDataSourceStr().

Do you need an event handler at all? If it's a custom form, you could put the logic directly to clicked(), instead of using an event handler. Except of the fact that clicked() isn't a good place for business logic. When you put code directly to the form, or to an extension, you can refer to the data source simply by name. Using an event handler makes things more complicated.

Another approach is putting the logic to a class (with main() method) and creating an action menu item. Then you can simply drag the menu item to a form. This allows you to use both the logic and the menu item (including the label and security permissions). In the form, you can set the Data Source property and access the record in main() by _args.record().

i have put the code on main() to upload attachment

final class DTPropertyfileUpload { public static void main(Args _args) { FileUploadTemporaryStorageResult result; DTProrpertyHeader dtProrpertyHeader; result = File::GetFileFromUser(classStr(FileUploadTemporaryStorageStrategy)); if(result.getUploadStatus()) { str fileName = "YourFileName.jpeg"; //Insert the name of the attachchment using(System.IO.MemoryStream stream = result.openResult() as System.IO.MemoryStream) { DocuRef docuRef = DocumentManagement::attachFile( DTProrpertyHeader.TableId, DTProrpertyHeader.RecId, DTProrpertyHeader.DataAreaId, DocuType::typeImage(), stream, fileName, null, fileName); } } } }

but i am getting error here , and at the time of devlopement of form i by mistake put the name Prorperty instead of Property , i have assign this class to menuitem and which will call by menu item button . can you please guide me on this .

You need to learn how to debug code, because that's an important part of developer's job.

You called DocumentManagement::attachFile() and it threw an error. Your next step shouldn't be asking strangers on internet; instead, look at the why the error occurred. Begin by opening the definition of attachFile(). At the very top, you'll see this code:

if (!_refTableId || !_refRecId || !_refDataAreaId || !_type || !_attachmentName || _file == null || !_fileName) { throw error(error::missingParameter(null)); }

This is cause - you call the method with one - or more - parameters empty.

The next is finding which parameter is empty. That can be done either by using the debugger, or by reviewing your code. You can easily notice that you made the most common mistake of yours - you declared a variable (dtProrpertyHeader) and completely forgot to put any value there. You'd immediately see the bug if you didn't completely forget to debug your code.

You're wasting time of both of us by not doing any attempt to debug your code. Instead of simply reviewing your code or running it in debugger, you wrote down a forum reply and keep waiting for a reply...
