Answer 1

Step1:
Create on local class
Class <LCL_EVENT_RECEIVER> Definition
Define the below public methods.
Method Name     HANDLE_TOOLBAR
Event Name     TOOLBAR
Event Class     CL_GUI_ALV_GRID
Importing     E_OBJECT, E_INTERACTIVE
Method Name     HANDLE_USER_COMMAND
Event Name     USER_COMMAND
Event Class     CL_GUI_ALV_GRID
Importing     E_UCOMM
Class <LCL_EVENT_RECEIVER> Implementation 
.     Method HANDLE_TOOLBAR
     Declare the structure <LS_TOOLBAR> of structure type STB_BUTTON
     Append the button information as given below into table E_OBJECT->MT_TOOLBAR to         display the custom button on ALV grid.
                           LS_TOOLBAR-FUNCTION = u2018DOWNu2019
                     LS_TOOLBAR-QUICKINFO = u2018downloadu2019
                     LS_TOOLBAR-TEXT = u2018downloadu2019
     Method HANDLE_USER_COMMAND
In this method if E_UCOMM = u2018DOWNu2019 write your logic.
Step2:
1.     To excluding the ALV grid buttons, fill the <LT_EXC> with function code CL_GUI_ALV_GRID=>MC_FC_EXCL_ALL
2.     To generate the ALV Grid, call the method SET_TABLE_FOR_FIRST_DISPLAY
Class     CL_GUI_ALV_GRID
Method Name     SET_TABLE_FOR_FIRST_DISPLAY
Exporting     
I_STRUCTURE_NAME      ZDS_CM_EXT_SEL
LS_LAYOUT                    <LS_LAYOUT>
IT_TOOLBAR_EXCLUDING     <LT_EXC>
Changing     
IT_OUTTAB                    <GT_EXT_SEL>
Create the Instance for class <LCL_EVENT_RECEIVER>
Class     <LCL_EVENT_RECEIVER>
Instance Name     <LO_EVENT_FNAME>
Now set handler  <HANDLE_USER_COMMAND> and <HANDLE_TOOLBAR_FNAME> events using instance <LO_EVENT_FNAME>
Call method 'SET_TOOLBAR_INTERACTIVE' to raise event TOOLBAR
Class     CL_GUI_ALV_GRID
Instance Name     <GO_GRID>
Method Name     SET_TOOLBAR_INTERACTIVE
