OO ALV - How to highlight cell after value change

[che_eky]

Hi All,

I have an OO ALV with an input enable column and would like to highlight a cell in a different color when the user changes it's value.

I am using pr_data_changed->get_cell_value to check the cells value has changed and pr_data_changed->modify_cell to update the cell with the new value.

The output table has a field called CELLCOLOR of type LVC_T_SCOL which I am using to highlight the cell in red:

lw_cellcolor-fname = 'THISFIELD' .

lw_cellcolor-color-col = '7'.

The ALV layout is also correclty set using: layout-ctab_fname = 'CELLCOLOR'

All the above is working fine and the changed cell is highlighted HOWEVER it only works if I call METHOD g_grid->refresh_table_display

Is there anyway to highlight the cell without calling method refresh_table_display??????

I do not like to call method refresh_table_display in an ALV event. The main reason is if a user changes a cells value and at the same time selects the row for update then the method refresh_table_display wipes out the row selection marker.

So Is there anyway to highlight the cell without calling method refresh_table_display??????

All your help appreciated

Try this way

In the PAI use

call method get_selected_rows

This will get you the row index of the selected rows from the screen for example I_ROW

In PBO

call method g_grid->set_selected_rows
 exporting
  it_row_no = i_rows[].

then call refresh_table_first_display

So this one will keep row selection after the refresh_table_first_display method

Hi a®s,

PAI and PBO are not called, this is all done in the HANDLE_DATA_CHANGED event. As a temporary solution (may become permanent) I am using something similar to your solution:

handle_data_change

---get_selected_rows

---refresh_table_display

---set_selected_rows

The above is working, would still like to know if it can be achieved without calling refresh_table_display in an event.

Hi,

Try this :

In the handle_data_changed method implementation, call the method get_selected_rows and store this in the event handlers attritbute.

And in the handle_data_change_finished method( which is the event handler method for data_changed finished of cl_gui_alv_grid ) call the set_selected_rows passing the table that you stored in previous method.

I'm not sure if this will work , but worth a try.

regards,

Advait
