Hello Experts,

My requirement is to create a table dynamically with multiple column groups shown as below.

-

---

column grp3

-

---

columngrp2

columngrp2

-

columngrp1

Now, I need to display column group3 as a checkbox and I need to set link-to-action for column group1 & 2.

Please help me out to achieve these function. Thanks in Advance.

Hi,

The below code creates a Main Group and under which has Goup1 under which you have two columns

with input fields. Similarly you can create columns with check box or link to action.

Write the following into wddomodify of your view.

   data lr_cont type ref to cl_wd_uielement_container.
  data lr_input TYPE REF TO cl_wd_input_field.
  data lr_input1 TYPE REF TO cl_wd_input_field.
  data lr_table type REF TO cl_wd_table.
  DATA lr_table_column TYPE REF TO cl_wd_table_column.
  DATA lr_table_column1 TYPE REF TO cl_wd_table_column.
  DATA lr_column_group TYPE REF TO cl_wd_table_column_group.
  data lr_cap TYPE REF TO cl_wd_caption.
  data lr_cap1 TYPE REF TO cl_wd_caption.
  data lr_cap2 TYPE REF TO cl_wd_caption.
  DATA lr_caption TYPE REF TO cl_wd_caption.
  data lr_group type REF TO cl_wd_table_column_group.
  data lr_mgroup type REF TO cl_wd_table_column_group.

  lr_cont ?= VIEW->GET_ELEMENT( 'ROOTUIELEMENTCONTAINER' ).

  CALL METHOD CL_WD_INPUT_FIELD=>NEW_INPUT_FIELD
    RECEIVING
      CONTROL             = lr_input.
  lr_input->bind_value( 'NODE.ATTR1' ).       "Context path of the attribute to be displayed
  data : lr_flow TYPE REF TO cl_wd_flow_data.
CALL METHOD CL_WD_FLOW_DATA=>NEW_FLOW_DATA

    ELEMENT     = lr_input
  RECEIVING
    CONTROL     = lr_flow.

CALL METHOD CL_WD_TABLE_COLUMN=>NEW_TABLE_COLUMN

CALL METHOD CL_WD_TABLE_COLUMN=>NEW_TABLE_COLUMN
  RECEIVING
    CONTROL  = lr_table_column1.
lr_table_column1->set_table_cell_editor( lr_input1 ).
lr_table_column1->set_header( lr_cap1 ).

  RECEIVING
    CONTROL             = lr_cap2.
lr_mgroup->set_header( lr_cap2 ).
lr_mgroup->add_column( lr_group ).

CALL METHOD CL_WD_TABLE=>NEW_TABLE
  EXPORTING
    BIND_DATA_SOURCE              = 'NODE'
  RECEIVING
    CONTROL                       = lr_table.
lr_table->set_layout_data( lr_flow ).
lr_table->add_grouped_column( lr_mgroup ).

lr_cont->add_child( lr_table ).

Hi Harshith,

Thanks for your reply. Yeah I have already done the above part but my requirement was to assign a check box for column group not for a column. I tried many ways but couldn't achieve that. Now the requirement got changed and I have achieved the functionality in different format.

Thanks and regards,
