Hi expert ,

i need to display the records in text view one by one from a table

this is my code ,

LOOP AT lt_question INTO wa_question.

attribute_data->set_attribute( name = 'RECORDS' value = wa_question-qtext ).

ENDLOOP.

but it assigns the last value only in the textview , what should i do?

Regards

Of course that would be the case with the code that you provided. When you use set_attribute, it overwrites the current value with the new value. You need concatenate the text together. I would suggest something like this.

data l_string type string.
LOOP AT lt_question INTO wa_question.
 concatenate l_string wa_question cl_abap_char_utilities=>cr_lf into l_string. 
ENDLOOP.

attribute_data->set_attribute( name = 'RECORDS' value = l_string ).

That is what the cl_abap_char_utilities=>cr_lf was for - if it didn't work; try cl_abap_char_utilities=>newline.

hi thomas,

now also it is displayed in same line even i used that

concatenate l_string wa_question-qtext cl_abap_char_utilities=>newline into l_string.

newline should work according to the online help:

Note that each occurrence of cl_abap_char_utilities=>newline in this property is replaced by a line break in the browser display.

For help with Dynamic coding check out these sources:

Have a look at the documentation for the WDDOMODIFYVIEW section of the phase model:

http://help.sap.com/saphelp_nw70ehp1/helpdata/en/d2/8acd409cc4dd50e10000000a1550b0/frameset.htm

There is also the class CL_WD_DYNAMIC_TOOL:

http://help.sap.com/saphelp_nw70ehp1/helpdata/en/67/6935425394033be10000000a1550b0/frameset.htm

Also have a look at the example application DEMODYNAMIC.

I've got an eLearning on the topic here as well:

You just need to adapt these sample to the textView UI element. The textView UI element class is CL_WD_TEXT_VIEW.
