Reading the label text and its corresponding field value dynamically in WDA

[former_member682881]

Hi Experts,

   I need your help in reading the Label Text and its corresponding VALUE of  input field / Dropdown field / Text view screen elements dynamically in Webdynpro abap.

   I have managed to get the Label text and Label For values and by using 'Label for'  value I can find out the corresponding screen field.  What I want is VALUE of Screen field.

   For example:

        Assume there is customer field with the value C00001.  I need to get the label of field and value of corresponding field programmatically.

   
                               -------------------------

      Customer         |   C00001              |

                               -------------------------

    Immediate help is greatly appreciated.

Best Regards,

Hi Sreenivasa,

Please follow the below steps to achieve your requirement

• Get the context binding of primary property of your ui element using method BOUND__PRIMARY_PROPERTY( ) of class CL_WD_UIELEMENT
• You would get the binding path of the context attribute like VIEW.NODE.ATTRIBUTE
• Use string operation to find node and attribute name.
• Then get the node reference and attribute values accordingly

Note: the method bound_primary_property( ) returns the binding path only if the UI element has a primary property like input field has VALUE as primary property

Hope this helps you.

Rama

Hi Ramakrishnappa,

    Thanks for the prompt response.

    I would appreciate if you could advice me to fetch the View instances from component controller.

    For example: I have 7 views in my Webdynpro and when I perform action and I need to get the all the views instances programmatically.

Hi Srinivasa,

Is your issue resolved? if not, please find my answer for your latest query.

The instances of views gets created/available once the views loaded / displayed.

To have the instances of all the views stored, you need to create global component attributes go_view1, go_view2.... go_viewN for each view of type IF_WD_VIEW and save the instance for first time in wddomodifyview

if first_time = abap_true.

     wd_comp_controller->go_view1 = view.

endif.

Similarly, write the same code in all other views

So, you can access the view instances whenever required.

Hope this helps you.

Hi Sreeni,

There is a concept in Webdynpro called "Context change log", try this concept to find the changes in a context. By this you can get the changed data.

Refer: Context change log | Team ABAP for implementation details.
