How to set focus at UI element ?

[danilo_henriques]

Hello,

I've been trying to set focus at UI element(Input Field) but i can't get no results. When i click the button, the method is executed but nothing happens.

Here is my code:

DATA: l_api TYPE REF TO if_wd_view_controller.

l_api = wd_this->wd_get_api( ).

l_api->request_focus(

context_element= Elem_I_Zceldes_Desenv_Fun

attribute = 'BNAME' ).

Can someone help me?

Hi,

Write in wddomodify() of view/

If init is the node name having attribute initwhich is bound to an input field and you want to set focus on it then following code works

DATA:

lo_node TYPE REF TO if_wd_context_node,

lo_element TYPE REF TO if_wd_context_element,

lo_view_contr TYPE REF TO if_wd_view_controller.

lo_node = wd_context->get_child_node( name = wd_this->wdctx_init ).

lo_element = lo_node->get_element( ).

********************************************************************************

*........ Step 1 : To set focus on field 'init'...............

********************************************************************************

if first_time = abap_true.

lo_view_contr = wd_this->wd_get_api( ).

lo_view_contr->request_focus( exporting context_element = lo_element

attribute = 'init' ).

endif.

Hi Praveen,

Write below code on OnEnter Action of the First input field.

data: lr_elem type ref to if_wd_view_element.

lr_elem = view->get_element( <ID of the second input field>).

if lr_elem is bound.

view->request_focus_on_view_elem( lr_elem ).

endif.

Do the same kind of proccedure for remaining input fields. i.e. OnEnter event of the second input field, set the focus on third input field with corresponding ID and so on....

Thanks,

Prashant

Hi Prasanth,

I am getting "Cannot user NULL reference as object error at view".

Can you please tell me how to get the reference of the "view".

Thanks

Hi all,

the last Post is right.

You have in every method or action the possibility with if_wd_view_controller->request_focus( ) to set the focus to an element.

Hi

try this

data: lr_elem type ref to if_wd_view_element.

lr_elem = view->get_element( 'IP_FIRSTNAME' ).

if lr_elem is bound.

view->request_focus_on_view_elem( lr_elem ).

endif.

IP_FIRSTNAME is the ID of my input field.

Hi Danilo

Try like this.

Here INP_PAR_LIFNR is the UI element id on the View

data: lv_v_elem type ref to if_wd_view_element.

lv_v_elem = view->get_element( 'INP_PAR_LIFNR' ).

if lv_v_elem is bound.

view->request_focus_on_view_elem( lv_v_elem ).

endif.

I've not used that method to set the focus before, so I can't say what might be wrong. However there is another API method of the View itself. You might try that:
