Event handling to the drop down list in the web dypro ALV.

Hi Experts,
In my dynpro ALV i have 5 fields. in that 2ed field has the drop down list.
if i select any of from the list, based on the particular selected value, some value should be reflect in the 3rd field of the ALV.
Ex:
dropdown list of 2ed fields inclued like below
AUXILIARY CONTROLLER
AXLE ASSEMBLY, NON-OSCILLATING
ACTUATOR, LINEAR
AIR CONDITIONER
BLADE, EARTHMOVING
if i select ACTUATOR, LINEAR the value ( ACT - first three letters ) should automaticaly reflects in the 3rd field of the ALV like below
Filed 2 Field 3
ACTUATOR, LINEAR ACT
I thnk we have to do the some Event handling for that dropdown.
I checkd in the SCN but i didnt find any solution to my issue.
Any solutions/sample code is appriciated.
For better visiblity( as i didn't get any replies ) I posted same thing in the ABAP Programing
Regards!

In Firefox 4, how do I get back the context menu for the drop down list of the Location Bar so I can Open Link in New Tab, which I did often in FF 3?

Firefox 3 has a context menu for the drop down list of
the Location Bar. One option on this menu I used often
is "Open Link in New Tab" -- quite convenient.
This context menu has disappeared in Firefox 4.
Can I get it back?

The "Use custom settings for history" setting allows to see the current history and cookie settings, but selecting that setting doesn't make any changes to history and cookie settings.<br />
Firefox shows the "Use custom settings for history" setting as an indication that at least one of the history and cookie settings is not the default to make you aware that changes were made.<br />
If all History settings are default then the custom settings are hidden and you see "Firefox will: (Never) Remember History".<br />

How to populate the values in the drop down list form the xml file ?

I want to populate the drop down list values from a seperate xml file called ReferenceData. I created this file, which consists of a mapping entry in the form of ( key,value ) pair. Am mapping this xml file in to form by using rule named as getAppReferenceData.
But the values are not getting populated in the form. And I have a doubt of, where should we keep that xml file? (under which path / folder ).

what would help is if you showed what you do in the rule, either the code or a express trace of the rule.
The other thing you need to know is where you want to get the file from. Yes java can read a file from anywhere on the system but there is a security layer in there which might prevent the file being opened. Have you allowed acces to the file via the security policy settings via java.io.FilePermission?

Where is the drop down list with "edit web part" for a list??

In Sharepoint 2010, there was a drop down list to the far right of a list. One of the options was to Edit Web Part. In Sharepoint 2013, I can't find the drop down list. Nothing is to the right of my list and mouse overs down't reveal
anything. I am trying to get to that area to change my toolbar type. Any clues as to where the "edit web part" has gone to?

I've been able to edit Web Part properties for weeks, but a few days ago, I could no longer do it, either by using the checkbox in the upper right corner of the web part or by using Web Part Properties in the Web Part tab. It's greyed out.
Then yesterday I could do it again and today I can't. An intermittent problem!
No one has changed any Sharepoint Admin settings.
Anyone have any ideas? They would be greatly appreciated.

How to open the Drop Down List on the "enter" event?

I am trying to find a way for the users to see the expanded drop down list options without using their mouse to click on the down-arrow.
I am able to add script to the "enter" event so when user key-broad-tabbed into the drop down field, the first items of the list shows up:
dropdown1.selectedIndex = 0
However, it would be nice if at the same time, they can also see the rest of the options within the drop down expanded.
Any help/hints would be appreciated
Thanks in advance
p

It would even be nice if the PDF could default with the small arrow already displaying instead of having having to click the field, then click the arrow. I'm just hoping adobe would add this in a future version.

Master Password Feature: After sometime (10-15 min.) the drop down list for the field on any site does not show; opening new window (not refresh or new tab) drop down appears.?

I manage a ton of accounts for different customers suing the same login pages (GoDaddy, WordPress, etc.) I use the Master Password Feature to help keep track of the many variants in logins and passwords.
After some unknown period of time, even closing the page tab so a new page session is started at the remote server, Firefox does not provide me with the usual drop-down selection list of the previously used login names. However, if I open a new FF window (file/new window) from the menu bar, the drop down becomes available.
How can I refresh the original window session in FF or change the timeout length?

Well, you said LOV...that might mean you are using JDev 11g. Are you? If so what technology stack are you using?
Assuming you are using JSF (?) you might be "backing" your list component in the application scope...but that is not likely.
If you are using ADF/BC on your business component level, you can clear your view object from which you are querying the possible values of this list...unless your you have made a method to compile this list...in which case you know what you are doing...so that is probably not the case.
Essentially you want to requery the VO upon which your LOV is based...unless you are using JPA or something...and then I know "requery" is not the right word...is it?

Different Files Returned when using the Drop Down list on the Search Results Page

Hi
I have a result set of 22 documents when I select Date (Newest) from the drop down on the search results page. The third document down is called "LL".
If I now select Date (Oldest) I have a result Set of 22 documents. However, when I move to the second page. The number of documents has reduced to 20 documents and my document "LL" which I would have expected to be the third from bottom document
is not there.
Am I doing something wrong here ? Search is OOTB. I have added some refiner columns.
Regards
Nigel

Hi Nigel,
It is by design. The "About x results" is presented when the total number of results is uncertain, and that is when collapsing (i.e. duplicate detection in this case) is enabled and the result set is partially processed. By default, a result page
shows 10 results at the time. Therefore, for result sets with less than or equal to 10 results you will always get an accurate number of results and hence “About” is omitted. For more than 10 results you will get the “About x results” on the first page until
you get to the last page of results and only then we know the exact number of results and hence can omit the “About”.
Note that when you page out in the result set you will notice that the X in the “About X results” can vary quite a lot. That is because the total number of results is estimated based on the collapsing done so far. This is a common way of doing it by other
search engines as well.
Here is a simlar post for your reference:

I hope this helps.

How do I delete an individual web address from the drop-down list of the address bar?

I'm using FF 36.0.1 for Ubuntu.
I used to do that with just Delete button in earlier version. Now nor Del, nor Shift\Ctr+Del do not working. Is this a bug?
Please don't tell me about history in menu. I won't go there every time I need to delete a broken url.

Note that is this item has a star at the right then it is a bookmark and you would have to remove the bookmark to remove that item permanently.

Drop Down List - Setting the Default Selected Item

I have a drop down list in my application that gets populated by a remote database. When you select an item from the list, a screen full of thumbnails is populated based on the selection. We have decided that when the user gets to this component in our air application, that it looks too empty and barren. All that displays is a drop down list with an empty screen. So we would like to set a default setting for the drop down list so that when the user gets to this component, a screen full of thumbnails is awaiting them and they can change it if they want. My first instinct was just to set the selectedIndex property of the drop down list to the value that we want as the default, and that works, but it only changes the label in the dropdownlist, it doesn't actually populate the screen with the thumbnails. That is because when an item is selected, it has to be commited to the drop down list by a CLOSE event that then sets off the close handler that populates the screen with thumbnails. So after looking at the documentation, I found that there is a method called closeDropDown that states the following:
closeDropDown
method
public function closeDropDown(commit:Boolean):void
Close the drop-down list and dispatch a DropDownEvent.CLOSE event.
Parameters
commit:Boolean — If true, commit the selected data item.
When I use this method, nothing happens. In fact if I add a listener for the CLOSE event, the close event isn't getting fired. So I am a little befuddled. The only thing that I can figure is that I am setting the selectedIndex and not the selectedItem before I call the closeDropDown method, and if you look above, the documentation vaguely states that that "If true, commit the selected data item". Do I need to set the selectedItem and not the selectedIndex? If so, I am not exactly sure how to do this since I am using a service to populate my drop down list which kind of makes the dataprovider a little unclear to me in the code because it gets replaced by an AsyncListView. Here is what I have.
<fx:Script>
     <![CDATA[
        protected function dropDownList_creationCompleteHandler(event:FlexEvent):void{
          getAllAudio_descriptionsResult.token = audiodescriptionsService.getAllAudio_descriptions();
          getAllAudioResult.token = audioService.getAllAudio();
     private function audioDescriptionsCallResponderHandler(event:ResultEvent):void {
          audioDesc = event.result as ArrayCollection;
     private function audioCallResponderHandler(event:ResultEvent):void {
          audio = event.result as ArrayCollection;
          audioDescDropDown.selectedIndex = 2;
          audioDescDropDown.closeDropDown(true);
     ]]>
</fx:Script>
<fx:Declarations>
     <s:CallResponder id="getAllAudio_descriptionsResult" result="audioDescriptionsCallResponderHandler(event)"/>
     <audiodescriptionsservice:AudiodescriptionsService id="audiodescriptionsService" fault="Alert.show(event.fault.faultString + '\n' + event.fault.faultDetail)" showBusyCursor="true"/>
     <s:CallResponder id="getAllAudioResult" result="audioCallResponderHandler(event)"/>
     <audioservice:AudioService id="audioService" fault="Alert.show(event.fault.faultString + '\n' + event.fault.faultDetail)" showBusyCursor="true"/>
</fx:Declarations>
<s:DropDownList id="audioDescDropDown" x="43" y="65" width="185" height="34" fontFamily="MyriadProSemiBold"
                    fontSize="15" skinClass="skins.VideoSkins.Video.DropDownSkin"
                    color="0xE6E6E6" selectionColor="0x054F7C" rollOverColor="0x007CBA"
                    creationComplete="dropDownList_creationCompleteHandler(event)" labelField="audioCatName"
                    itemRenderer="renderers.DropDownList3" close="DDLAudioCloseHandler(event)">
     <s:AsyncListView list="{getAllAudio_descriptionsResult.lastResult}"/>
</s:DropDownList>
I would really appreciated hearing from anyone who has experience or insight into setting a default for a drop down list and actually forcing it to execute that default selection. Any thoughts at all would be helpful. Thanks!

I don't see your close handler in the code you posted, so if you provided it and I missed seeing it, please forgive me. I'm a bit unclear on why the open and close of your dropdown list is so critical to your functionality. It seems to me that the page of data would be tied to the item selected in the drop down (which to my mind is the only purpose for the drop down to be there). So why do you first need to open and close the drop down, rather than just taking the selected value and doing whatever you'd normally do with it to populate that page?
What I'm getting at is that I'd expect that page to be a separate component that would just have a property for the selected "thing", and that you could populate it either manually, as I suggested, or through the close handler on your drop down--I wouldn't think that there should be a need to go through the close handler every time. Even if you don't have it implemented the way I'm thinking, you may want to think about whether you need to go through the close handler every time, or whether you could break it out so that the close handler simply determines which item to select, then jumps to another function that actually does something with the selected value. That way, you don't have to go through the overhead of opening and closing the drop down if you need to change its value programmatically.

How to increase the width of the drop down list box in SSRS multi value parameter

Hi,
I am using SSRS 2012. I have a parameter, which accepts multi value.
The width of the drop down list box is very small, and the user need to scroll to the right to view the complete view of the content in the list box. But, if I don't use multi value then the length is good. Kindly suggest how to I increase the width
of the list box when it set to multi value parameter.
Thanks in advance,
Mahalengam Arumugam

Hi Mahalengam,
After testing the issue in my local environment, I can reproduce it. When the values for a single parameter are too long, the drop-down list of the parameter will automatically enlarge to an appropriate size. While the values for a multiple parameter are
too long, we need to scroll to the right to view the complete view of the content in the list box in SSRS 2008. But in SSRS 2008R2 and SSRS 2012, we can directly drag the black control at the bottom of the list box to control the size.
The following screenshot is for your reference:
If there are any other questions, please feel free to ask.
Thanks,
Katherine Xiong

Hi Katherine,
Thanks for your reply. I understood we need to drag the list box to a maximum size to view the contents.
But, this seems an additional task, i know this is a limitation in the current version of SSRS and hope it will be resolved in the next versions.
Thanks for your efforts,
Mahalengam Arumugam

How do I delete names from the drop down list when I login to gmail and facebook?

When I login to gmail and facebook several login names used in the past show up in a drop down list. I want to remove some of these names. How do I do that?

On Mac you need to use Shift+Delete

*Highlight an entry in the drop down list
*Press the Delete key (on Mac: Shift+Delete) to remove it.

Getting the rawValue of a Drop-Down list on the "change" event

I am having problems getting the rawValue of a Drop-Down list on the "change" event. It seems that you have to select the same item twice in a row to get the rawValue to be the value of the selected item.
::dropdownlist onChange event::
xfa.host.messageBox(this.rawValue);
On the first time a value is selected you get 'null'. The second time the same value is selected, you get the selected value.
Does anyone have any thoughts on why this is happening? Also, I CANNOT use xfa.event.newText, I need to use the rawValue of the dropdownlist.
Thanks

The change event occurs before the rawValue is changed. If you NEED to use the rawValue you'll need to use a later event. Perhaps you could use exit so that it gets triggered when the field loses focus?
