Drop Down in ALV Flashes and Disappears.

Hi All,
I have a strange issue going on. In an ALV (built on CL_GUI_ALV_GRID) I have got an editable field with a drop down option.Now lets say I have 10 rows in an ALV. I chose an entry from the drop down in one of the rows (this happens OK) and immediately after that I go on a click on drop down for any other row. What happens is that the drop down for the new row that I am in flashes and disappears. Now if I click for the drop down again the drop down appears. Basically whenever an entry is selected in one of the rows, drop down function immediately after that does not work. I have a feeling that it has something to do with the data _changed event but I am not sure how to handle that event.
I saw a similar thread [ALV Menu Flash|ALV HANDLE_DATA_CHANGED_FINISHED; but could not figure it out.
Any suggestions ?
Thanks

Hi,
Let us see the code and check it
Make the necessary changes at the fieldcatalog
clear ls_fcat.
ls_fcat-fieldname = 'COURSE'.
ls_fcat-col_pos = 5.
ls_fcat-coltext = 'Course'.
ls_fcat-outputlen = 10.
ls_fcat-DRDN_HNDL = 25.
ls_fcat-edit = 'X'.
APPEND ls_fcat to lt_fcat.
and in the class cl_gui_alv_grid we have one method SET_DROP_DOWN_TABLE
and it is having one parameter called iT_DROPDOWN of type LVC_T_DROP
generate the internal table and call the method set_drop_down_table
clear ls_drop.
ls_drop-handle = '25'.
ls_drop-value = 'ABAP'.
append ls_drop to lt_drop.
clear ls_drop.
ls_drop-handle = '25'.
ls_drop-value = 'CRM'.
append ls_drop to lt_drop.
clear ls_drop.
ls_drop-handle = '25'.
ls_drop-value = 'WEBDYNPRO'.
append ls_drop to lt_drop.
CALL METHOD o_grid->set_drop_down_table
EXPORTING
it_drop_down = lt_drop.
Thanks & Regards.

Drop Down in ALV ABAP and NOT in OO - ABAP

Hello Everyone....
I m workin on an ALV which is in simple ABAP and not in OO-ABAP. There is some selection criteria on the first screen , as soon as the user fulfills the requirement an ALV GRID is displayed in which the last column is editable.
But the Problem is that i wanna make that editable field in ALV as drop down which would contain values from the database table.
Suggest me some method , so that i dont have to do much changes in my code .
A Sample code will be very benificial .
Thanx n Regards,
Harpreet.

Hi Harpreet,
[compiled from sap online help - always a good chice]
To make an input/output field into a list box, you must set the value L or LISTBOX in the Dropdown attribute in the Screen Painter. The visLg attribute determines the output width of the list box and the field. You can assign a function code to a list box field. In this case, the PAI event is triggered as soon as the user chooses a value from the list, and the function code is placed in the SY-UCOMM and OK_CODE fields. If you do not assign a function code, the PAI event must be triggered in the usual way that is, when the user chooses a pushbutton or an element from the GUI status.
If you have assigned a list box to an input/output field, you can use the Value list attribute of the screen element to determine how the value list should be compiled. There are two options:
Value list from input help (recommended)
If you do not enter anything in the value list attribute, the text field uses the first column displayed in the input help assigned to the screen field. The input help can be defined in the ABAP Dictionary, the screen, or a POV dialog module. It should be laid out in two columns. The key is automatically filled.
Value list from PBO modules (not recommended).
If you enter A in the value list attribute, you must fill the value list yourself before the screen is sent (for example, in the PBO event) using the function module VRM_SET_VALUES. When you do this, you must pass an internal table with the type VRM_VALUES to the import parameter VALUES of the function module. VRM_VALUES belongs to the type group VRM. The line type is a structure consisting of the two text fields KEY (length 40) and TEXT (length 80). In the table, you can combine possible user entries from the KEY field with any texts from the TEXT component. You specify the corresponding input/output field in the import parameter ID.

The next screen (statically defined) for screen 100 is 100. The only input field on the screen is the component SDYN_CONN-CARRID. Its Dropdown attribute is set to L, and it has the output length 20. The Value list attribute is empty, and it has the function code SELECTED. The function codes of the buttons EXECUTE and CANCEL. CANCEL are defined in the GUI status as having the function type E.
The screen flow logic is as follows:
PROCESS BEFORE OUTPUT.
MODULE status_0100.
PROCESS AFTER INPUT.
MODULE cancel AT EXIT-COMMAND.
MODULE user_command_0100.
PROCESS ON VALUE-REQUEST.
FIELD sdyn_conn-carrid MODULE create_dropdown_box.
Users cannot enter any values into the screen fields. When they choose the input field on screen 100, the system displays a list box. The Value list attribute is empty, so the system launches the input mechanism. In this case, the event block PROCESS ON VALUE-REQUEST is created in the screen flow logic. This event block controls all other mechanisms. A two-column internal table is filled in the appropriate dialog module and passed to the input help using the F4IF_INT_TABLE_VALUE_REQUEST function module. The system inserts the two columns of the table into the list box.
When the user chooses a line in the list box, the PAI event is triggered using the function code SELECTED and the value in the first column of the internal table is copied to the input field.

Clemens

How does one come to know this..drop down in ALV in WD

Hello Friends,
                      I had a requirement of adding a drop down in ALV, i eventually got it but I have some questions about it
I used the following code and got the drop down
lr_column = lr_column_settings->get_column( 'BWART' ).
CREATE OBJECT lr_input_field
    EXPORTING
      value_fieldname = 'BWART'.
lr_column->set_cell_editor( lr_input_field ).
DATA : LR_DROPDOWN TYPE REF TO CL_SALV_WD_UIE_DROPDOWN_BY_KEY.
CREATE OBJECT LR_DROPDOWN EXPORTING SELECTED_KEY_FIELDNAME = 'BWART'.
LR_COLUMN->SET_CELL_EDITOR( LR_DROPDOWN ).

LS_VALUESET TYPE WDR_CONTEXT_ATTR_VALUE,
LR_NODE TYPE REF TO IF_WD_CONTEXT_NODE,
LR_NODEINFO TYPE REF TO IF_WD_CONTEXT_NODE_INFO.
LR_NODE = WD_CONTEXT->GET_CHILD_NODE( 'RETURN_NODE' ).
LR_NODEINFO = LR_NODE->GET_NODE_INFO( ).
LS_VALUESET-VALUE = '973'.
LS_VALUESET-TEXT = '973'.
APPEND LS_VALUESET TO LT_VALUESET.
LS_VALUESET-VALUE = '222'.
LS_VALUESET-TEXT = '222'.
APPEND LS_VALUESET TO LT_VALUESET.
LR_NODEINFO->SET_ATTRIBUTE_VALUE_SET( EXPORTING NAME = 'BWART' VALUE_SET = LT_VALUESET ).
My question is ... how does 1 know which class to use? how to use that class... most of concepts about OOPS are clear.. but i still cant figure out how does 1 find out which class to use.. is it all by expericence..

In short: Yes, by experience. Then again, for WD4A there is a class for each UI-Element available. Once you know this, you can easily search se24 for CLWD<UI-NAME>* or the like.

Made a drop down menu. How can I get the drop down to fade in and out? !

Hi guys!
I've created a drop down menu (with the help of you legends on here! )...Now I just need it to animate so when the user hovers over the main menu item, the drop down fades in.
Here's the HTML I have...
    <ul id="nav">
        <li><a href="#">Nav 1</a></li>
        <li><a href="#">Nav 2</a></li>
        <li><a href="#">Nav 3</a>
            <ul>
                <li><a href="#">» Sub Menu 1</a></li>
                <li><a href="#">» Sub Menu 2</a></li>
                <li><a href="#">» Sub Menu 3</a></li>
                <li><a href="#">» Sub Menu 4</a></li>
            </ul>
        </li>
        <li><a href="#">Nav 5</a></li>
        <li><a href="#">Nav 6</a></li>
    </ul>
...and here's my CSS...
ul#nav {width:920px; height:35px; list-style:none; padding:0; margin:0; background:url(navBg.jpg) repeat-x; z-index:999;}
ul#nav li a:hover, #nav li a:active {background:url(navOn.jpg) repeat-x; text-decoration:none;}
ul#nav li a {color:#E0E2E7; display:inline-block; float:left; margin:0; padding:10px 19px; width:auto; text-decoration:none;}
* html #nav li {display:inline; float:left; } /* for IE 6 */
* + html #nav li {display:inline; float:left; } /* for IE 7 */
#nav ul {width:208px; left:-9999em; list-style:none; margin:35px 0; padding:0; position:absolute; z-index:999;}
#nav li:hover ul {left:auto;}
#nav li {float:left;}
#nav li li a {width:190px; background-color:#efefef; color:#2e2e2e; padding:8px; margin:0; }
#nav li li a:hover {background-color:#000; background-image:none; color:#FFF;}
#nav li:hover {background:url(assets/images/frame/navOn.jpg);}
From what I can make out, I assume I need either Javascript or JQuery...
Does anyone know how I can get the drop down to fade in and out?
Thank you very much and I hope to hear from you.
SM

Yes, you'll need a client-side script to do fade-in/fade-out fx. Look at jQuery Superfish.

In develop "mode" and I can't locate my "Basic" slider that opens up my "Treatment" sliders. There's not even a drop down arrow to Minimize and open. I was working in it and the next moment it was gone. I'm in Lr 5 using a trackpad. Seems like the issue came up while using my trackpad. Any thoughts?

In the Develop Module, you right-click on one of the other Panel Headers (for example, Tone Curve) and then place a check next to Basic

Itunes not showing elements 11 drop down list of albums and won't sync, says ïtunes cannot sync, required folder cannot be found. ï have tried re installing both but no success. pls help!!!

Hi, Itunes won't sync my photos to ipad from elements 11. itunes doesn't show drop down list of albums and says Ipad "......cannot be synced, required folder cannot be found" i have tried re installing both programs but no luck. pls help!!!

I managed to finally fix the problem in a relatively painless way. It turned out that the problem wasn't on my phone, the problem was with iTunes. I completely uninstalled iTunes from my PC and then reinstalled it and everything was fine.
In order to completely uninstall iTunes, I did two things:
Used RevoUninstaller to uninstall iTunes. This cleans out a bunch of extra things that the normal iTunes uninstaller misses.
Searched for any iTunes folders/files on my computer (using the freeware utility called Everything) and deleted them manually.
I hope that works for you.

Audio MIDI Setup - drop-down menu of mfrs. and devices empty?

As the subject says, I'm trying to set up my small arsenal of MIDI gear, and the drop-down lists of manufacturer and device names in the Audio MIDI Setup->MIDI window are empty (there are supposed to be dozens of items to choose from). I've just recently performed a new installation of Snow Leopard, and everything is up to date. I even installed Garage Band, thinking that its installation might fix the missing MIDI device list, but no luck. Another odd thing is that my MOTU MTP AV is recognized by name within System Profiler (as an attached USB device), but I had to install drivers for it to appear in the MIDI Setup window.
Anyone experience this and/or have a solution? I own Pacifist, and if someone knows where the missing files are located within the SL installer disc I could try a custom installation. Help...

same problem here, no more device manufacturers and names, but a bigger problem to me is that I see no way of reorganizing the view in the MIDI window anymore, it puts all my devices next to each other, with 30 devices that makes it totally unusable.

Drop down in ALV with key and description

I want to show drop down in my ALV.
I am able to show description by setting the handle and value fields.
But I want to set like VRM_SET_VALUES -> That is user sees description, but internally I get key.
Is it possible?

<<Please don't just post links>>

Please suggest me where we are going wrong.
Thanks in advance...!!!

Hi Shashi,
Your code looks okay. Debug & check if everything goes fine and all the required list of values getting bound to node.
Is any code after this logic, which sets data to table ? if so, that logic is wiping out the drop down list values from context node.
Final check point:
Read the context node 'TABLE' and fetch records into internal table in WDDOMODIFYVIEW( ) method to make sure that, every row of your table contains the drop down list entries in "LEAVE_VALUES" attribute
Hope this helps you.

Rama
