file upload and view in web dynpro abap

[Former Member]

Hi experts,

I m developing an application in web dynpro abap. There is one tab for attachments. When i attached the attachments and press upload button, immediately it should be appear in the below table(filename, file type, file size, file content). And when i click on file content link file should be open. How can i achieve this? What is the data element for file content.. why because i need to save it in a z-table...

thanks in advance   ramana

Hi Ramana,

Create context node as follow

CONTEXT

|

|-----FILE_UPLOAD

|      |----NAME

|      |----CONTENT - XSTRING

|      |----TYPE

|----FILE_LIST

       |---NAME

       |---CONTENT -XSTRING

       |---TYPE

FILE_UPLOAD's cardinality should be 1. And bind the corresponding attributes of FILE_UPLOAD to FileUploadUIElement's properties.

FILE_LIST cardinality should be 0 to n. Now create a table with data binding to FILE_LIST node and show two fields, NAME and TYPE.

NAME filed should be FileDownload UI Element. Now bind the CONTENT of FILE_LIST to data property of the FileDownload UI Element.

Have a button named upload.

In upload button write code, for adding the data from FILE_UPLOAD to the internal table of FILE_LIST.

RAWSTRING is the data type to store file in the database.

Hope this helps you.

Hi Fareez,

Thanks for ur reply,

I m doing the same what u specified....  but not  getting..

When i created table with 4 fields.. file content type rawstring.. it is saying that need to create domain.. is dat not predefined?...

after clicking file upload button i m getting dump...

because of select query..

here is my code....

DATA LS_FILE_UPLOAD TYPE ZITER_MED_FILES.

   DATA LT_FILE_DOWNLOAD TYPE TABLE OF ZITER_MED_FILES.

   DATA LO_ND_UPLOAD TYPE REF TO IF_WD_CONTEXT_NODE.

   DATA LO_EL_UPLOAD TYPE REF TO IF_WD_CONTEXT_ELEMENT.

   DATA LS_UPLOAD TYPE WD_THIS->ELEMENT_UPLOAD.

   DATA LO_ND_DOWNLOAD TYPE REF TO IF_WD_CONTEXT_NODE.

   DATA LT_DOWNLOAD TYPE WD_THIS->ELEMENTS_DOWNLOAD.

   LO_ND_UPLOAD = WD_CONTEXT->GET_CHILD_NODE( NAME = WD_THIS->WDCTX_UPLOAD ).

   LO_EL_UPLOAD = LO_ND_UPLOAD->GET_ELEMENT( ).

   LO_ND_DOWNLOAD = WD_CONTEXT->GET_CHILD_NODE( NAME = WD_THIS->WDCTX_DOWNLOAD ).

   LO_EL_UPLOAD->GET_STATIC_ATTRIBUTES(

     IMPORTING

       STATIC_ATTRIBUTES = LS_UPLOAD ).

   LS_UPLOAD-FILE_SIZE = XSTRLEN( LS_UPLOAD-FILE_CONTENT ).

   LS_FILE_UPLOAD-FILE_NAME     = LS_UPLOAD-FILE_NAME.

   LS_FILE_UPLOAD-FILE_TYPE     = LS_UPLOAD-FILE_TYPE.

   LS_FILE_UPLOAD-FILE_SIZE     = LS_UPLOAD-FILE_SIZE.

   LS_FILE_UPLOAD-FILE_CONTENT  = LS_UPLOAD-FILE_CONTENT.

   INSERT ZITER_MED_FILES FROM LS_FILE_UPLOAD.

   IF SY-SUBRC EQ 0.

     SELECT FILE_NAME

         FILE_TYPE

         FILE_SIZE

         FILE_CONTENT

         FROM ZITER_MED_FILES

         INTO TABLE LT_DOWNLOAD.

     LO_ND_DOWNLOAD->BIND_TABLE( NEW_ITEMS = LT_DOWNLOAD SET_INITIAL_ELEMENTS = ABAP_TRUE ).

   ELSE.

   ENDIF.

Hi Ramana,

Create a domain with data type as RAWSTRING and then try. Probably that should be the reason for the error in Select query. From your message, it seems that insert query worked alright. Go to se16 and check whether data is uploaded successfully to database.

You did not show what datatypes you have used for your context nodes. Check whether it is compatible with the datatypes of the database.

thanks and regards

Hi Ramana,

This is because, each row in a table is enabled only if it is having corresponding data bound in the internal table bound to the context node. Now create an internal table of 30 records with empty string and bind it with the table. You would be able to enter then.

Otherwise on the OnEnter of the input field write code to add one more empty record to the context node using bind_element. This will make the next row editable.

Hope this will help you

An obligation. Hereafter when you have a different question start a new thread. This will help everyone to have look on that and you will also get a variety of answers.

Thanks & Regards ,
