ALV-Toolbar : Control the &LOCAL& Buttons

Hi, all
I have the following problem with ALV-Toolbar.
If I use editable ALV-Grid Control, I get in the toolbar new buttons such as DELETE_ROW or UNDO. This buttons dont trigger any events of the class CL_GUI_ALV_GRID.
If I look at Function Code of such buttons in the Table mt_toolbar they are quiet similar. All of them have &LOCAL&.
How could I control this buttons with my program .
Many thanks for your help
Vladimir Golovtchiner

Hello Anand,
Thank you for your answers.
I thought that these buttons are belonged to Front-End.
I hope that ALV-Grid is an OCX. Or not? If it is an OCX-Object, is it possible to communicate with it?
I have no any idea now, how to solve that, but I could explain to you why I need to handle these buttons.
I use an editable Grid of CL_GUI_ALV_GRID. For the last two columns I use Drag and Drop to move data from the pre-last column to the last column. It work properly until the following situation:
For example I have two rows in a Grid. I place the cursor to the last row and press the button COPY_ROW two times ( I have 4 rows in a Grid now). Immediately after that I try to do Drag&Drop at the last row (4th) from the Grid. As I drop the cursor on the last cell of the last row I get always the result in the last cell of the 2nd row ( the last row before I insert two rows).
It doesnt matter how many rows I had or how many rows I inserted to the Grid. It happens also in the middle of the Grid not only at the end.
After the first Drag&Drop it begins to work properly.
I debugged the handler of Drag&Drop and I saw that the Drag&Drop object has in the structure E_ROW each time the number of the last row before insertion. I forced the update of backend in the handle of on Drag event with CHECK_CHANGED_DATA before I create the Drag&Drop object and passed the Drag&Drop handle to the internal table. It didnt work.
That is why I thought that I should do this update after each insertion or deletion with these buttons.
In other words I dont want to change the functionality of these buttons I want to add something before.
Best regards

Is there a way to control the "back button"?

i've got a simple animation intro, ending with the very last
key frame being static with links. then the links will bring up
another page in the same window. but i was wondering if there was a
way in flash to control the back button to bring the user to that
very last key-frame, at the end of all the animation. thereby
skipping over the intro-animation.
also:
i have an html intro page, where you can go to the flash
introduction, or the peoples' old website, or to a Flash-Player
download window. i was wondering if there was a way to create a
link to that end key-frame in order to by-pass the animated flash
intro.
thanks for your help

gotoAndPlay(32) if you have a continuos animation after that
frame and you want to continue it; the number within the brackets
is the number of the frame you want to go to. Or else if you want
to go to a particular frame and stop there, gotoAndStop(32);

Control the *GO* button in interactive report

How to control the GO button in interactive report using dynamic action?
i have to press the GO button automatically using dynamic action when page item get focused.
Is it possible?
thanks and regard,
skud.

Hi skud,
Your dynamic action can capture the "Get Focus" event of your page item and then you could try creating a true action to submit the page with a specific request. Create a branch to a URL with the condition of request being equal to the one you specified before, and as target select URL and make use of the filtering of an IR by URL when linking. This is just an idea, hope you can get the result you need.

Sergio

Controling the run button from user interface

I'm trying to eliminate the complete toll bar and give the user a button on the interface to control run mode

I'm not sure that's possible in the sense that you're talking about.
You can eliminate the toolbar by making the vi appear as "dialog"
(Right Click on VI icon [top right front panel]->VI
properties->window appearance->dialog), or you could customize it.
But to run the vi itself cannot be done by a button click, as
the vi has to be running in order to register that click. What
you could do, is run the vi on start, then have it hang on maybe an
event structure or default case of a state machine until the "start"
button is clicked.

Why can't I open links in a new tab with a right click anymore? And why has the toolbar removed the refresh button?

Several basic functions seem to be have vanished from Firefox. I can no longer open links in new tabs with a right click, and the refresh browser button (and back/forward navigation buttons, etc) do not appear in with consistency anymore. How do I get these basic navigational tools back? (most recent updates are installed)
== This happened ==
Not sure how often
== 7 July 2010

* Make sure that you have the "Navigation Toolbar" and the "Bookmarks Toolbar" visible: "View > Toolbars"
* If items are missing then see if you can find them in the "View > Toolbars > Customize" window
* If you see the item in the Customize window then drag it back from the Customize window to one of the toolbars.
* If, in "View > Toolbars > Customize", you do not see that item then click the "Restore Default Set" button

Control the yes button on the af:inputFile

I have an option where the user loads a excel file and shows the data in a table and finally exports data to a new excel file. When the user wants to load the af:inputFile opens a popup up with two buttons ok and cancel. How can i control the action of the OK button to clean the data of my table??.

Hi,
I interpret the question for how to respond to the OK button. For this you define a dialog listener on the af:dialog component, which creates a managed bean method like
public void handlerName(DialogEvent dialogEvent){ ... }
You can then call
//oracle.adf.view.eich.event.DialogEvent.Outcome
Outcome outcome = dialogEvent.getOutcome();
if(outcome = Outcome.ok){
clean up the table

How do I control the compare button on ESX24

I am playing around with the ESX24. I load an acoustic piano setting and when I start playing around with settings, some of them seem to turn the "compare" button on and the sound goes bad, meaning it changes it so that it doesn't sound like the piano anymore. It will happen just from moving the lower half of the level ball all the way up. When I click the compare button it resets everything to the default. What is going on? I understand that the compare button on plugins can be used to compare settings but why is it acting like this? I am new to this so I assume that there is something obvious that I am missing.

the compare button on the logic plugins will toggle between the current settings and whatever settings were last saved.

Move filter and settings in WD ALV toolbar to the left ?

Hello WD abap experts,
The WD ALV has one big disadvantage: When you have many columns, the alv table is very wide and if you then want to set the filter or change settings, you have to scroll all the way to the right to click filter or settings, then scroll back all the way to the left to change the settings.
I wonder if I could change the layout of the toolbar in a way that the filter and settings links appear first on the left, (before the view dropdwon) instead on the right.
Has anybody done this ? I cannot find the view in SE80, probably it is generated dynamically ?
Johannes

Hi,
Check the cl_Salv_wd_config_table for the standard functions settings. I guess there is no option to move them left.
if_Salv_wd_standard_function or filter setting ones...check them out..

When I check my e-mail,the toolbar with the delete button is gone. How do I restore it?

How do I restore it?

Under View in the Mail Menu bar go to customize toolbar and drag what you want back down to Mail toolbar.

I closed then reopened my navigation toolbar using the Alt button. When it re-opened the add-ons(?) that were on it were no longer there. I'm specifically looking for two add-ons that took me to "Major Television channels" and "Minor television channels".

I would be content just to have the add-ons back, the one that allowed me to view ABC, NBC, CBS and a handful of other channels, and the one that connected me to the National Geographic channel and I believe some of the Discovery, etc channels . I can get to the Nat Geo if I go through my history but most of the other channels I can't. I've had MozFire on my computer for a while but mainly used Google Chrome until last week when I decided to check out MozFire. As has happened in the past I found myself really liking this program and wondering why I haven't been using it all along.

Radio button in ALV toolbar

Hi experts,
I have a requirement to add 2 radio buttons on ALV toolbar.
I try to implement the toolbar event of class cl_gui_alv_grid, and add 2 radio buttons using the following code:
       move 'RAD' to ls_toolbar-function.
       move 'RADIO1' to ls_toolbar-quickinfo.
       move 'RADIO1' to ls_toolbar-text.
       move '4' to ls_toolbar-butn_type.
       move ' ' to ls_toolbar-disabled.
       move 'X' to ls_toolbar-checked .
       append ls_toolbar to e_object->mt_toolbar.
       clear ls_toolbar.
       move 'RAD' to ls_toolbar-function.
       move 'RADIO2' to ls_toolbar-quickinfo.
       move 'RADIO2' to ls_toolbar-text.
       move '4' to ls_toolbar-butn_type.
       move ' ' to ls_toolbar-disabled. "#EC NOTEXT
       append ls_toolbar to e_object->mt_toolbar.
But when I run this program,I find these 2 radio buttons look like normal button, is this correct?
And I don't know how to catch which radio button is checked or not.
Anyone having code for it or any suggestion for it, kindly let me know...
Thank you

Controlling the desableing of command buttons

I have been having a great deal of trouble trying to work out how to control the command button such that if the rowset is null then the button is disabled. The trick is that the rowset is not defined by the view where the command button is located. The rowset is defined by a view which has a "view" command button which displays the specific row selected, then this view has a command button that will display the detail rowset of the selected master row, but if there are no detail records I want the button to be disabled. How can I do this in ADF JSF? If I use a backing bean to make the determination prior to the page rendering then how does the backing mean method set the parameter necessary to disable the command button? Any advice or tutorial that I can use is most appreciated. My goal with using ADF JSF effort was to demonstrate that a complex app could be generated with minimum coding, I would like to keep to this concept if possible. Thanks,
Michael

Wrong forum. You need the ADF or JDeveloper forums.

Hi Michael,
You can probably set the Enabled property of the command button using an EL that would evaluate and return true or false based on your requirement.
Check out these links for more information on using the EL.
