Multiple Listbox (dropdown) in ALV

All,
I have an ALV using class CL_GUI_ALV_GRID (Editable) and have drop down in 2 different columns , using following but in display both the columns shows same drop down values as OR & AND.
Any Info?
ls_fcat-fieldname = 'DROPDOWN_F4_1'.
ls_fcat-datatype = 'INT4'.
ls_fcat-checktable = '!'.
ls_fcat-no_out    = c_x.
append ls_fcat to pt_fieldcat.
clear ls_fcat.
ls_fcat-fieldname = 'DROPDOWN_F4_2'.
ls_fcat-datatype = 'INT4'.
ls_fcat-checktable = '!'.
ls_fcat-no_out    = c_x.
append ls_fcat to pt_fieldcat.
ps_dropdown-handle = '1'.

Using multiple LISTBOX in single Policy of Microsoft Group Policy .adm file?

OK, I am writing a .adm file and here is code for a policy within a category
CATEGORY !!A_CATEGORY
POLICY !!A_POLICY
KEYNAME "Software\Policies\ABC\ListBoxes"
PART !!PART_1_Text LISTBOX
ALUEPREFIX "FirstListBox"
END PART
PART !!DestPort_Label LISTBOX
VALUEPREFIX "SecondListBox"
END PART
END POLICY
END CATEGORY
The .adm file is successfully loaded in group policy editor without any problem and shows two list boxes too. I can give input for both list boxes and apply/ok without any problem. The real problem is that on registry location "Software\Policies\ABC\ListBoxes",
there comes only registry values as SecondListBox1, SecondListBox2, SecondListBox3 .... and no values for FirstListBox. Ideally, there should also be FirstListBox1, FirstListBox2, FirstListBox3 ...
I did some experiments and found that only the registry values with last PART (i.e. SecondListBox) are shown in registry and all other PART values before that are ignored. Lastly, the problem is only with multiple LISTBOX in a single policy. I can use multiple
CHECKBOX, COMBOBOX, DROPDOWNLIST, EDITTEXT, TEXT and NUMERIC within a single policy without any problem both in Windows 2003 Server and Windows 2008R2 Server
Baig

> and no values for FirstListBox. Ideally, there should also be
> FirstListBox1, FirstListBox2, FirstListBox3 ...
Since you do not use "ADDITIVE" it seems the whole key is cleaned out
before processing the second list. Give it a try :)

Multiple column dropdown

I need help with creating a multiple column drop down menu. I found jquery mega menu but I was wondering if there's a way to do this in dreamweaver. any help is apprciated.

Hi Nancy,
Designers don¹t care about coding issues and browser compatibility. They
want what they want. I know I could do it with css3 but that doesn¹t help
with IE. And the rest of the world still depends on IE. I¹ve found a way
using images and the jquery megamenu. It¹s a lot of code and a little messy.
Man I hate IE!

Multiple Row Select in ALV

Hi All.
I am trying to set multiple selection on in ALV using the method SET_SELECTION_MODE of IF_WD_SELECT_OPTIONS. (if_salv_wd_table_settings)
But it is always resulting in a dump saying that :
Selection type Multi is not allowed in combination with the selection Single of the data node
Now how can we change the context of the ALV?
What am i doing wrong here?
Thanks.

Hi this works fine here:
data: lr_table_settings type ref to if_salv_wd_table_settings.
lr_table_settings->set_read_only( abap_false ).
lr_table_settings->set_enabled( abap_true ).
lr_table_settings->set_selection_mode( CL_WD_TABLE=>e_selection_mode-multi ).
The node i bound to the ALV has selection 0..n.
Cheers,
Sascha

Selecting multiple rows of an alv

Hi All,
I have a requirement where in i have to select multiple rows of an alv and when i click a button i should get the data of all the selected rows, i am able to select only one row by default , how to select multiple rows or records,i am new to this Web dynpro alv , can aynbody please help me on this.
Thanks,
Praveen.

hi, praveen kumar.
About how to make "Multiple-select" of ALV available, you can take a reference of the following coding. Just one example:
****ALV Config****
DATA:
      lr_salv_wd_table TYPE REF TO iwci_salv_wd_table,
      l_value TYPE REF TO cl_salv_wd_config_table,
      lr_table_settings TYPE REF TO if_salv_wd_table_settings.
   lr_salv_wd_table = wd_this->wd_cpifc_alv_child( ). "Your statically declared ALV component usage
   l_value = lr_salv_wd_table->get_model( ).
* tabel setting
lr_table_settings ?= l_value .
lr_table_settings->set_selection_mode( cl_wd_table=>e_selection_mode-MULTI ).
About how to get your selected records of ALV, you can make use of the context node bound to your ALV component. For example,
****get selected elements****
lt_elems = lo_node->GET_SELECTED_ELEMENTS(
      INCLUDING_LEAD_SELECTION = abap_true ).
These are just examples. For detail, you can search them.
Thanks.Best wishes.

Automatically Selecting Values in Multiple Values Dropdown Parameters

Hi,
Is it possible to have parameter values automatically selected in a dropdown in an SSRS report? I'm using SQL Server 2008 R2 Enterprise edition. Basically what I have in mind is this: The user wants to save his parameter selections in a
table that will be available as a dropdown parameter of a report, call it
ParamUserSelection. ParamUserSelection is the first parameter of the report and other parameters depend on it.
We have two other parameters called ParamCountry and
ParamState. These are dropdown text parameters that allow multiple values to be selected. Populating the list is not a problem as I use a standard cascading parameter technique. What I'm trying to do is the following:
The user selects a value from ParamUserSelection, call it Selection1. Selection1 is stored in a table and has all the values that should be selected in ParamCountry and ParamState. In other words, it should tell these two subsequent parameters,
what values should be selected in their respective dropdowns. For example if the user selects Selection1 from ParamUserSelection, it reads the values in the database table and if it finds US and Canada for countries and CA, NY, ON for states, ParamCountry
should be populated with all the countries available in the database but should have ONLY US and Canada as selected values and ParamState should be populated with all the states in the database but should have ONLY CA, NY and ON as selected values.
If then I click on selection 2 and it has ParamCountry = US, ParamState = TX,OH in its database then again all countries and states should be in the dropdown but only US for ParamCountry and TX,OH for ParamState should be selected.
Is this possible with SSRS? I've tried using the Default Values tab with a dataset that returns all the selected values under Report Parameters Properties but this only works for the first time that I select ParamUserSelection. It appears that
if I change the value of ParamUserSelection again, the default values are not invoked.
If this is possible, please tell me how to do this as I have been struggling for a day with it.

Hi Comedian,
According to your description, you have a report with three parameters (ParamUserSelection, ParamCountry, ParamState). The available value lists of ParamCountry and ParamState are based on the selection of a value for ParamUserSelection. Now you want to
show all countries and states in their parameter dropdown list when selecting a user selection instead of only showing the cascading values. Right?
In Reporting Service, when we want a parameter to show the cascading values, we only need to set the corresponding dataset and field for Default Values in this parameter. In this scenario, if we want to show all countries and states in their dropdown list,
we just need to set another dataset for Available Values in those parameters so they can display all countries and states. We have tested your case in our local environment. Since you have done with the cascading parameters, we just give some part of steps
and screenshots for your reference:
We created two tables (dbo.Selection, dbo.states) based on your information.
Create one more dataset (named dataset2) in your report, put text below into your query:
select distinct Country from states
Create another dataset (named dataset3), put text below into your query:
select distinct State from states
Go to your ParamCountry, in Available Values, select dataset2 and Country for dataset and field.
Go to your ParamState, in Available Values, select dataset3 and State for dataset and field.
Save and preview. It looks like below:

How to select multiple records in the ALV POP UP by using oops

Hi All,
We have a requirement of ALV POP UP by using the OOPS. How to select the multiple records in the POP UP and After selecting that i want do Inteactive ALV means again one more POP UP in ALV.
Thanks for help....
Regards,
Bharani

Hello Bharani
Displaying an ALV list in a popup is by no means different from a list displayed on a main screen. The only thing you need to consider is that you set the right screen level when creating the parent container for the ALV.
For more details refer to thread in CL_GUI_SPLITTER_CONTAINER ALV list is not show in called screen
" step 1:
CREATE OBJECT gr_spliter
    EXPORTING
      parent = cl_gui_container=>screen0 " For first popup use: =>screen1
      rows = 1
      columns = 2.

Multiple Hotspots in a ALV Grid single column

Hi Experts,
My ALV Grid report output looks like below....
If you observe below output, column 3 has multiple documents each one separated by ' ; '. Now, I would like to assign hotspot on each documents like DOC1, DOC2, DOC3, etc.
Heading#:          COL1 | COL2 | COL3 |
Records1:              1      | xxxxx | _DOC1_ ; DOC2 ; *DOC3*
Records2:              2      | xxxxx | _DOC1_ ; DOC5 ;
I know, we can assign hotspot for entire column. but my requirement is multiple hot spots in a single column.
Please help me on this?
Thanks in Advance
Raghu

As I mentioned earlier,
My ALV Grid report output looks like below....
Heading#: FIELD1 | FIELD2 | FIELD3 |
Records1: 1 | xxxxx | DOC1 ; DOC2 ; DOC3
Records2: 2 | xxxxx | DOC1 ; DOC5 ;
If you observe above output, field 3 has multiple documents each one separated by ' ; '.
When I click on DOC1, it supposed to display related picture on the POP-Up Screen. Similarly when I click on DOC2, it supposed to display that document picture on POP-up screen.
Before going to do this, first I need to assign hotspots on each documents like DOC1, DOC2, DOC3, etc.
Please help me.

Multiple selection in the ALV is not possible after system upgrade

Hi Colleague,
I had been using an ALV, which was performing as desired before, but recently we had a system upgrade to NW7.0 and after that in this ALV multiple selection of records/rows is not allowed.
The colleagues who upgraded the system suggested that this may be because this ALV is instantiated at many places. I would request you to kindly provide a solution for the same ASAP, as I am not able to proceede ahead.
Warm regards,
Roopesh

Hi all,
Thanks for your replies, I had figured out the actual problem. The reason was, the referance of the selected rows was lost as I was doing bind elements to the context after moving to wddomodify.
So I figured out an alternative solution to avoid binding on selection of records.
Best regards,
Roopesh

Multiple line header for ALV

I am using CL_SALV_TABLE (List_Display = X) to create a ALV report. I am willing to change it to function module REUSE_ALV_LIST_DISPLAY if it serves my requirement.
The header for the report needs to be multiple lines (8 lines). How can I accomplish this?
I looked into the possibility of using TOP_OF_PAGE event but I will have to hard code the vertical positions of the headers and since it is ALV and you can remove columns at will, I dont think this solution will work. Also if the columns are optimized or output length changed by the user, the positioning of the headers will be ruined.
Currently the header can only be of one line, how can we make the header to display a table of contents.
H1-L1          H2-L1          H3-L1
H1-L2          H2-L2          H3-L2
H1-L3          H2-L3          H3-L3
H1-L4          H2-L4          H3-L4
H1-L5          H2-L5          H3-L5
H1-L6          H2-L6          H3-L6

Thank you.

Please guide me hw to put internal table field at report header in ALV.

How to provide view selection dropdown like ALV

Hi all,
As you know, ALV can save your own view but it's embeded in component SALV_WD_TABLE. And I want to provide such a dropdown on selection screen before searching. Can I reference this dropdown directly?
I've found out the db tables that store these info wdy_conf_usert and WDY_CONF_USER. It's feasible to select out relevant entries and fill the dropdown. Anyway, I don't think it's a good idea because I have to do so for each screen.
Thanks,
Felix

Multiple Input Rows In ALV Grid (Editable)

Hi,
I have an editable ALV grid and need to have multiple blank rows ready for input. Something similar to what happens when you click the "New Entries" button in SM30 (Table Maintainance).
There is a local function for appending lines in the ALV grid toolbar but this only allows a single entry.
I have replaced the local function with my own button (same icon etc) and on user_command event, I am appending several blank lines to my output table.
However these lines are not being shown on the screen. I have looked through the layout and field catalog but there is no field to allow blank lines to be shown.
My 2 questions are:
1. Is there some standard way of entering multiple entries in ALV Grid Editable.
2. If not then how to allow blank lines to be shown as ready for input.
Also if someone could suggest a way to do error checking for all entries on the screen especially duplicate entries I will be extremely grateful.
Many Thanks,
Preet

Hi, Preet!
You can easily do whatever checks you wish. You should declare an event handling method for event DATA_CHANGED and call the ADD_PROTOCOL_ENTRY method of the ER_DATA_CHANGED event parameter (it's an object of the class CL_ALV_CHANGED_DATA_PROTOCOL). You must not forget to set handler for your ALV grid.
For example, this piece of code checks for all changed fields resulting in error message if they are initial. In short, this makes all the fields obligatory.
METHODS: on_data_changed FOR EVENT data_changed OF cl_gui_alv_grid IMPORTING er_data_changed.
SET HANDLER your_object->on_data_changed FOR your_alv_grid.
METHOD on_data_changed.
DATA: s_mod_cell TYPE lvc_s_modi.
LOOP AT er_data_changed->mt_mod_cells INTO s_mod_cell.
    IF s_mod_cell-value IS INITIAL.
*       issue message 'Make an entry in all required fields'
        CALL METHOD er_data_changed->add_protocol_entry
          EXPORTING i_msgid     = '00'
                    i_msgno     = '055'
                    i_msgty     = 'E'
                    i_fieldname = s_mod_cell-fieldname
                    i_row_id    = s_mod_cell-row_id.
    ENDIF.
ENDMETHOD.
Furthermore, if you make your class inherited from CL_GUI_ALV_GRID you can make use of protected attribute MT_OUTTAB which is a data object referencing your output table. Then you can have:
FIELD-SYMBOLS: <outtab> TYPE STANDARD TABLE.
ASSIGN me->mt_outtab->* TO <outtab>.
* do whatever you want with <outtab>
Hope this helps.
Kind regards,
Igor
P.S. Regarding the blank lines that you need, what's wrong with standard ALV grid buttons "Append row" and "Insert row" which appear whenever the grid is editable (unless you deliberately remove them)? They work just fine with me (just like on SM30). I don't see reason for programatically appending lines to your internal table.
