ALV table in edit mode

Question

hi all,
   have a requirement where I have to create a webdynpro for ABAP table for new row/rows entry, delete row/rows and update row/rows data. This is something like table control in normal ABAP.
how can I achieve this? Is there any such feature in ALV component?
Any code sample will be really helpfull.
Please help!
Thanks
Ravi

Hi Ravi Raju
     In alv you can edit, add and append rows. First you have to initialize the ALV usage in WDDOINIT method of the view in which SALV_WD_TABLE is added as component usage. Then you have to disable the read only attribute of the ALV. If you set the property to abap_false, then append, insert, delete buttons will be added automaticaly. Then you can set the appropriate cell editor for each column.
initialize ALV Component
l_ref_cmp_usage =   wd_This->wd_CpUse_Alv( ).
if l_ref_cmp_usage->has_active_component( ) is initial.
  l_ref_cmp_usage->create_component( ).
endif.
Get model data
DATA: l_ref_INTERFACECONTROLLER TYPE REF TO IWCI_SALV_WD_TABLE .
l_ref_INTERFACECONTROLLER =   wd_This->wd_CpIfc_Alv( ).
  data:
  l_VALUE type ref to Cl_Salv_Wd_Config_Table.
  l_VALUE = l_ref_INTERFACECONTROLLER->Get_Model( ).
set read only mode to false (and display edit toolbar)
data: lr_table_settings type ref to
if_salv_wd_table_settings.
lr_table_settings ?= l_value.
lr_table_settings->set_read_only( abap_false ).
set cell editor for input fields (~make colum editable)
DATA: lr_column TYPE REF TO cl_salv_wd_column.
DATA: lr_column_settings TYPE REF TO if_salv_wd_column_settings,
lr_input_field TYPE REF TO cl_salv_wd_uie_input_field.
lr_column_settings ?= l_value.
lr_column = lr_column_settings->get_column( 'SAMPLE' ).
CREATE OBJECT lr_input_field EXPORTING value_fieldname =
'SAMPLE'.
lr_column->set_cell_editor( lr_input_field ).
Hope it helps ;>)
