Change Label text at runtime (WebDynpro)

[Former Member]

Hey,

I just want to change the text property of a label or a textview at runtime.

Sadly I couldn't apply the solutions I found on my problem somehow.

I got a button which triggers an "onAction"-Event. There I want to change the text of my label.

A promising option was this post

When I used the code:

data lr_lbl type ref to  cl_wd_label.

lr_lbl ?= view->get_element( 'LABEL1' ).          "label1 is the ID of the label UI element

LR_LBL->SET_TEXT( 'New Text' ).

I got the error that "REF TO" could only be followed by "a class", "a interface" or "DATA".

"cl_wd_label" is a class and there's nothing else following what can cause an error I think.

Does anybody got an idea or just knows how to simply change the text-property of a label at runtime?

Thank you!

Hi,

Instead create one attribute and bind it to text property of that label & set the attribute value as per your requirement.

I figured out how to change the context attribtue with the help of these three pages.

-> Attribut-Wert eines Context-Elements lesen - Web Dynpro für ABAP - SAP Library

-> SET_ATTRIBUTE method of interface IF_WD_CONTEXT_NODE - Web dynpro ABAP - SAP
