working with two custom containers on same screen

former_member185116 — Wed, 23 Dec 2015 08:11:29 GMT

hello all,

we have developed a Z-Report like this,

when i click the hotspot field on first container the corresponding data is displayed on second container,

however if no data exists for that particular record,

i tried to display message (MESSAGE 'No data Exists' type 'I')...

but the problem is when i select another record(which has data) it is throwing error,

********this is my code*************************

The first time that you show the ALV grid in the second container, use (as you do) Set_Table_For_First_Display. Thereafter, if grid2 has already been instantiated, replace the data in Grid2's source table and then call method refresh_table_display.

Or....

Go the long way round and completely dispose of Grid2 and recreate it but that's overkill.

Which error did you got?

Hint: Use the variant "handle" field to distinguish both ALV catalogs/variants and prevent some errors.

Raymond

hi richard,

thanks for your quick reply,

that is fine,but i want to display a message (when no data exist)...

Re: working with two custom containers on same screen

Former Member — Wed, 23 Dec 2015 08:39:27 GMT

Easy,

clear the source data table, refresh the second grid and then use the MESSAGE statement with a type I message.

However, I was answering your question:

"but the problem is when i select another record(which has data) it is throwing error,"

Also take note of Raymonds reply.

Regards

hi,

call method grid2->set_table_for_first_display outside the IF condition of custom container 2.

as your custom container object is not initial after the first selection that's why you are getting this prompt.

thanks!!

Hi,

where you are throwing the error,I mean your validation part for checking the data exists for the particular record or not?

If my guess is right you are throwing the Information massage for error , So even after the error the below code is being executed this should be the problem

try using

MESSAGE <your message> TYPE 'E' DISPLAY LIKE 'I'.

Hope this helps.

Chintu6august — Wed, 23 Dec 2015 08:58:55 GMT

hi,

it should be like this

MESSAGE <your message> TYPE 'I' DISPLAY LIKE 'E'.

after the error the below code will execute.

thanks!!

hi richard,

solved half part,

but when i display 'No data Exist' message ,at the same time i need to disable the data on the right side,

the data on the right side(which is previous records data) should disappear...

Re: working with two custom containers on same screen

Former Member — Wed, 23 Dec 2015 12:46:34 GMT

The data will (or should) dissappear once your user selects the green tick on the message box, however, you could try:

Call Method cl_Gui_Cfw=>Flush( ).

Place this after you refresh the grid and before you display the message.

As an aside, replace the hotspot_click event with a selection changed event, something like this:

*
*               Add additional handlers to handle the changed row events etc
*
                Call Method Me->Register_Delayed_Event
                     Exporting
                       i_Event_Id = Me->Mc_Evt_Delayed_Change_Select
                     Exceptions
                       Others = 1.
*
*               Change the delay reaction time to make the grid more reactive -
*               hence the lcl wrapper class.
*
                Me->Set_Delay_Time( ).
                Set Handler: Me->Handle_Del_Chgd_Sel_CBack For Me.

Then, when your user moves up or down the grid, the data on the left will change (if you put your code for populating grid2 in the correct handler), and if there is no data it will just appear blank.

richrad,

Call Method cl_Gui_Cfw=>Flush( ). is not working....

is there any other method which makes to disappear data on right side when green tick is selected on message window...

or else is it an efficient programming skill to again call

CALL METHOD GRID1->SET_TABLE_FOR_FIRST_DISPLAY

with an empty table data...

Re: working with two custom containers on same screen

Former Member — Wed, 23 Dec 2015 13:24:29 GMT

Are you calling refresh_table_display after updating the table used by the grid ? When I say updating I mean either updating with the records you wish to display, or clearing the table if there are no records ?

There is no reason to call set_table_for_first_display after your first call - Refresh_table_display is there to do eaxctly what it says.

I have no problem in doing exactly the same as you do:


  method REDISPLAY.
*
*        Column width optimisation does not work.
*
*        From OSS note 1009650
*
*             [12] Within the ALV Grid, the system calculates the optimal column width only during the
*             first call due to performance reasons.
*
*             If the method CL_GUI_ALV_GRID->REFRESH_TABLE_DISPLAY is called for the grid instance, the system
*             does not optimize the grid again.
*
*             To force the grid to be optimized again, the methods CL_GUI_ALV_GRID->GET_FRONTEND_LAYOUT and
*             CL_GUI_ALV_GRID->SET_FRONTEND_LAYOUT must be called before the method
*             CL_GUI_ALV_GRID->REFRESH_TABLE_DISPLAY is called. The transfer of the parameter CWIDTH_OPT = 'X'
*             ensures that the column widths are calculated again.
*
*             In the object model of the ALV (package SALV_OM), you must reset the column optimization by calling
*             the method cl_salv_columns->set_optimize before you call the method cl_salv_table->refresh.*
*
         Data: ls_Stable Type ALV_Stable_Flags.
*
         ls_Stable-Row = Abap_True.
         ls_Stable-Col = Abap_True.
         Me->Set_FrontEnd_Layout( Me->Get_Wrapper_Layout( ) ).
         Me->Refresh_Table_Display( Exporting is_Stable = ls_Stable ).
         Free: ls_Stable.
  endmethod.
