For check box selections use


 
gr_selections = gr_table->get_selections( level = 1 ).
gr_selections->set_selection_mode( cl_salv_selections=>if_salv_c_selection_mode~multiple ).
 
gr_table->display( ).

For Ttitle


  gr_display = gr_table->get_display_settings( ).
  gr_display->set_striped_pattern( cl_salv_display_settings=>true ).
 gr_display->set_list_header( 'This is your heading' ).

Basically "Editable" ALV is not supported with the ALV Object Model, so in the case of a editable checkbox in a regular table display is not possible. You can use the standard functionality of line selection instead. You would use the class CL_SALV_SELECTIONS, to turn this on. Are you interesting in doing this?

If you want to use the standard selection functinality of the grid, have a good look at the example program SALV_DEMO_TABLE_SELECTIONS

aRs has posted above about the checkbox using the same class, understand that what he has posted above is from a hierarchial sequestion list ALV, which does allow you to implemented checkboxes, but if you are using the regular tabular ALV, class CL_SALV_TABLE, you will not get checkboxes, but simply the row selector column in the grid.

Anothef example program SALV_DEMO_TABLE_FORM_EVENTS will show how to do the top of page for your report heading.

Well, you can display a column as a checkbox, but you won't be able to change it in the tabular ALV. You would need to use the standard selection column. Follow this tutorial.

If you follow the instructions in the tutorial step by step, it should help you understand what you need to do. What exactly are you having trouble with or what is not clear?

hi,

for adding editable checkboxes you can try this code, i got checkboxes by using this code.

go_column ?= go_columns->get_column( 'CHECK' ).

go_column->set_cell_type( if_salv_c_cell_type=>checkbox_hotspot ).

go_column->set_output_length( 10 ).

thanks and regards,

Actually you can implement full editable ALV using SALV class. (but usage is questionnable

Check this: /people/naimesh.patel/blog/2008/11/24/power-of-abap-objects-overcome-the-restrictions-of-salv-model

Quick step-by-step:

1. Inherit a local class LCL_SALV_MODEL from the CL_SALV_MODEL_LIST

2. Generate SALV model to generate the ALV object

3. Used narrow casting to get the CL_SALV_MODEL object from the ALV object

4. Passed this CL_SALV_MODEL object to the inherited class LCL_SALV_MODEL. Since LCL_SALV_MODEL is inherited from the CL_SALV_MODEL_LIST, it allows access to the R_CONTROLLER of the CL_SALV_MODEL.

5. Get the GRID object from the object MODEL -> Controller -> Adapter -> Grid.

6. Set the Layout for EDIT and Refresh the ALV.
