Displaying Cells as Pushbuttons 

Purpose

If you assign the style mc_style_button to cells, rows or columns, the ALV Grid Control displays the associated cells as pushbuttons. Users know immediately that they can obtain further information about the cell by clicking on the pushbutton. The ALV Grid Control then triggers the event button_click.

1. Define the layout structure of type LVC_S_LAYO .
2. Add a row table of type LVC_T_STYL to your output table, as shown in the following example:

DATA: BEGIN OF GT_OUTTAB OCCURS 0.
        INCLUDE STRUCTURE <DDIC structure> .

DATA:   CT TYPE LVC_T_STYL. "Table buttons

DATA: END OF GT_OUTTAB.

3. Select your data and copy it into the output table.
4. Read one output table row at a time in a loop. One row of the row table has the fields FIELDNAME and STYLE . Assign values to these fields as follows:

• If you want to display all cells of a row as pushbuttons, assign the attribute cl_gui_alv_grid=>mc_style_button to the field style . In this case, field fieldname remains empty.
• If you want to display only specific columns of the row as pushbuttons, append one row for each column to the cell table. Assign the name of the desired column to the field fieldname , and assign the attribute cl_gui_alv_grid=>mc_style_button to the field style .

6. Assign the name of the internal table to the field stylefname of the layout structure (in our case 'CT', see step 2).
7. Pass the layout structure and the output table using method set_table_for_first_display.
