hi Sirisha,

for example if u want to create a button with name new

then following code works.check it and u have to write this code in wddomodifyview()

data: LR_CONTAINER type ref to CL_WD_UIELEMENT_CONTAINER,

LR_BUTTON type ref to CL_WD_BUTTON,

lr_flow_data TYPE REF TO cl_wd_flow_data.

LR_BUTTON = CL_WD_BUTTON=>NEW_BUTTON( id = 'BUTT_1' text = 'NEW' on_action = 'CLICK' ).

LR_CONTAINER ?= view->GET_ELEMENT( 'ROOTUIELEMENTCONTAINER' ).

lr_flow_data = cl_wd_flow_data=>new_flow_data( element = lr_button ).

LR_CONTAINER->ADD_CHILD( LR_BUTTON ).

Reward points if usefull,

Hi,

With the help of implicit variable "view" we can get the reference of container and from there you can easily add button on it.

class for button: cl_wd_button.

Remember "view" is a impoting parameter of method wddomodifyview and only available there so if you want to create a button at some where else then you must this variable. you can declare the attribute of IF_WD_VIEW type and can take the instance of "view". With this you can access "view" at any point of time except in method "wddoinitialize".

Code to take reference of "view" :

m_view type if_wd_view "this should be declared in Attribute tab of View

if first_time = 'X'. " you will get "first_time" for free in the wddomodifyview method.

wd_this->M_view = view

endif.

Hi

check this code to create button dynamically.

DATA: lr_ui_root TYPE REF TO if_wd_view_element.

DATA: lr_button TYPE REF TO cl_wd_button.

DATA: lr_container TYPE REF TO cl_wd_uielement_container.

CALL METHOD io_view->get_element

EXPORTING

id = 'tc1' "transparent container name

RECEIVING

element = lr_ui_root.

lr_container ?= lr_ui_root.

CALL METHOD cl_wd_button=>new_button

EXPORTING

id = 'tc1' "transparent container name

on_action = 'ADD_ROW' "action"

RECEIVING

control = lr_button.

cl_wd_matrix_head_data=>new_matrix_data(

EXPORTING

element = lr_button ).

lr_container->add_child(

EXPORTING

the_child = lr_button ).
