Restrict the number of visible values in drop down by key?

Hello,
Is it possible to restrict the max. number of entries displayed in a drop down by key element? By default i get 10 entries which i would like to limit to 5. Thanks.

Vasu

Hi,
If you have a set of default values (which come from the domain), you can restrict them to the specific values which you need to display. In the INIT method of the view in which this UI element is present, you will have to write code to delete the entries which you do not wish to show in the drop down by key element.
Have a look at this code snippet:
data:     node_info type ref to if_wd_context_node_info,
            elem_attr type wdr_context_attribute_info.
node_info = wd_context->get_node_info( ).
node_info = node_info->get_child_node( 'CHILD_NODE' ).
data:    lt_valueset type wdr_context_attr_value_list,
        l_value type wdr_context_attr_value.
call method node_info->get_attribute
    exporting
      name           = 'ATTR1'
    receiving
      attribute_info = elem_attr.
lt_valueset = elem_attr-value_set.
delete lt_valueset where value = 'VALUE1'.
node_info->set_attribute_value_set(
            name = 'ATTR1'
            value_set = lt_valueset ).
Hope this helps.

Clear the values in Drop down by key

hi all ,
i m using drop down by key (Combo box) ..
i have populated some values in that ..
then i navigate to next view ... from that view i m again navigating back to the
previous view .. now the values which was filled needs to be cleared ..
i used invalidete method also even though the values are present in the list ..
can any one help in this ...
points will be rewarded
Thanks and regards
JK

Hi,
Do you want the currently selected value to be reset, or do you want to delete the entire list of values? If you want to only reset your current selection, node->invalidate( ) should do it. Invalidate your node in the inbound plug handler.

How can I increase the number of Tags displayed in Drop down list?

When I go to Bookmarks/Tags, there are only 10 tags displayed. I have created at least 15 tags.
Is there a way to increase the number of Tags displayed in the Drop down list?
Thanks

Do you mean "Recent Tags" which has an icon a blue-colored folder with a primitive looking magnifying glass over the folder?
That folder does have a limit of 10 results. If you want to create an "All Tags" item on the Boomarks Menu, you can do that by creating your own "smart folder." The process I use is a little involved, so bear with me (also, see the screen shots).
The query used by Recent Tags is:
place:type=6&sort=14'''&maxResults=10'''
So for All Tags we will drop the maximum results limit:
place:type=6&sort=14
''If you prefer your tags in alphabetical order instead of having the most recently used at the top, use this instead:''
place:type=6&sort=1
Go ahead and select the line you want and right-click > copy it.
Next, click the bookmarks drop-down button, expand the Bookmarks Toolbar, right-click any existing item, and choose New Bookmark.
In Location, paste the query, and in name, type All Tags (or your preferred description). When you click Add Bookmark, Firefox will add it, but it doesn't show the blue search folder icon. Drag the bookmark to the menu, and it will turn into a functioning search folder.
Success?

Increase the number of lines in a drop down list

Firefox offers up to 20 lines in its drop down lists with a slider to access additional lines. For example, on password entry, to select the n'th character of the password from A-Z and 0-9 requires a drop down list of 36 lines but only 20 are on offer - irritating time-waster. Can the number of lines be extended?

Where is that drop-down list, on a webpage?
Please provide a screenshot of that issue. <br />
https://support.mozilla.org/en-US/kb/how-do-i-create-screenshot-my-problem <br />
It is best to use a compressed image type like PNG or JPG to save the screenshot and make sure that you do not exceed a maximum file size of 1 MB.

How to set a default value in a Value Help Drop Down List

Hi,
I used an age Range field in my adobe form, the control is a Value Help Drop Down List. i am populating the drop down using following code.
IWDAttributeInfo ageInfo = wdContext.nodePersonalData().getNodeInfo().getAttribute("CTAgeRange");
     ISimpleTypeModifiable ageType = ageInfo.getModifiableSimpleType();
     IModifiableSimpleValueSet ageValueSet = ageType.getSVServices().getModifiableSimpleValueSet();
     ageValueSet.put("1","21-29");
     ageValueSet.put("2","30-34");
     ageValueSet.put("3","35 or Above");
My requirement is to set a default value e.g. 30-34 in the age range field.
I want to give input to iform from my Implementation code only.
Please help.
Thanks in advance

hi Ranjan,
that means you have to set at design time,
to set default drop down value you will have to set the value for particular attribute (which is linked to the dropdown element) in the context
like
wdContext.currentContext<nodeName>Element.set<FieldName>(<default value>)
This generally done in Initialization method of the controller.

On basis of drop down by key values i want to enable and disable ui elements is wda

How to enable and disable ui elements on basis of drop down by key values as i show in screen shot i have 3 values in drop down by key on basis of those values i need to enable and disable ui elements in webdynpro abap kindly reply back

Hi Sreedhara,
There are many tutorials on SCN for learning Web Dynpro ABAP. If the following steps don't make sense to you, please do a search for some tutorials and read through the tutorial materials. Hopefully the tutorials will help you to become familiar with some of the basics of Web Dynpro ABAP.
Here is how to enable or disable a UI element upon selection from a DropDownByKey.
In your view context, create a context attribute of type wdy_boolean. For now, let's call this attribute IS_ENABLED
In your view layout, bind the enabled property of the UI element to the context attribute IS_ENABLED.
In your view actions, create an action-- let's call it SET_ENABLED-- and bind this action to the DropDownByKey element's onSelect event in the view layout.
In the event handler method for the SET_ENABLED action, use the Code Wizard to read the value of the DropDownByKey selected value, then use the Code Wizard again to set the value of context attribute IS_ENABLED to either true or false.
Now when a value is selected from the DropDownByKey, the SET_ENABLED action will be triggered and the IS_ENABLED context attribute will be set to either true or false. Since your UI element's enabled property is bound to this true or false value via the context binding, the UI element will change to enabled or disabled.
Good luck!
Cheers,
Amy

How to restrict the number of Records into the Table?

Is there any way that I can restrict the number of records can be entered into the table?
For example I have created a table TAB1 with size category 0( zero).
User dont want to enter more than 100 values, How to restrict the number entries? Whether Basis can do it?
Regards,
Prathap

Hi Prathap,
You can write a code in table maintenance events to restrict the number of Records added into the Table to constant.
Solution:
Se11 -> enter table name (TAB1) -> F6 -> Utlities -> Table maint. generator -> Envirnment -> modification -> events -> write here the form routine name.
Double click on routine name. You will get into include section of the code. Write here code like:
IF current_rec_num > 100.
messgae error 'Entry restriceted to 100'
ENDIF.
Somewhat this way you can achieve your target.

Dashboard prompt issue (Restricting Values in drop down) ????

Hi Friends,
In my report I have "days to start" column which list almost 10,000 values ranging from -1000 to 5000.
I need to create a prompt for this report on "Days to Start" column.
When I create a prompt on Days to start with Operator "Greater than" and Control "Drop Down List" it shows me all the values in Drop down.
I need only specific Values like 30, 60, 90, 180 which might not be in the "days to start" column.
If I select "SQL Result" what should be the SQL for that??
Is there any other way to solve this problem
Aprreciate your help on this
Thanks

You could make a table VALUES with 1 column and fill it with values like 30,60,90....then in sql you'd write SELECT * FROM VALUES....as simple as that
(of course, it'd have to be in RPD, and you'd need to expose it in Presentation layer)

Also, you could try this - it works for me - but it could be slower and you might want to figure out how to round it - also, it has to be a number or cast to number format
SELECT Table."Column"/30 saw_0 FROM "Subj Area" ORDER BY saw_0

How to restrict the number of login attempts?

Hi,
Is there any "out of the box" solution to restrict the number of login attempts
in personalization server?
Thanks

why is it obvious he wants to restrict instances
of program, rather than instances in
it? it's not obvious, but it's what I think he meant
he asked "how to restrict the number of instances in
a program". it has the words "instances" and
"program" in it, but not the word "class". on face
value, yes, he's asking about instances within one
JVM. knowing a bit about how newbs minds work, I'm
reading between the lines and I reckon he meant
instances of his program. had he meant
"instances of classes" he'd have said so. "instances
in a program" sounds like somebody more experienced
talking, which if he was, he'd know how to do limit
either instances of classes or instances of
his program, and wouldn't be asking. I could be
totally wrong, but I don't think I am; that's what I
inferred from his post. only the OP knows for sureInteresting.
The OP also said "to any number". So you were guessing that this particular user wants to only permit, for example, five instances to be run on any one box at one time?

How to get the values of drop downs, which are gonna create at run time.

As per my design requirement, I have to create drop downs in an ADF display table.
The no# of rows of the table are gonna decide the no# of the drop downs. User can select the values from drop downs. My issue is, how can I capture the selected values of those drop downs as those are gonna created run time.

Hi
ohh ,ok ,then as u said that u r storing twenty values ,thats y i aksed earlier ,are these form values part of tbale ,or as u said 20 values are there ,for these u r creating 20 form values ???.
My suggestion would be ,u do four calculation and put all your results in a hashmap ,and keep this hash map in to sesion ,using the following method
pageContext.putTransactionTransientValue("HashMapName",myHashMap);
and inside the PFR method when u want to display these values ,u can loop through your hashmap and can display these values.
like this
HasMap hm=pageContext.getTransactionTransientValue("HashMapName");
thanx

Alert about the loading time & Restrict the number of the rows retrieved

Hi everybody, maybe the question is stupid, but I didn't find yet an answer...
I'm using BIP 10.1.3.4.1
Because I have many reports with a huge amount of data to display (in HTML format) and customers once clicked on "View" have to wait a lot of time, they asked me if there is the possibility to do the following things:
1. restrict the number of the rows retrieved (this for each report); this request has to be dynamic (different rows' number for each report and for each user); so, I can't modify the query into the data template in order to retrieve a fixed number of rows;
2. show an alert who says for example " The data loading will take 5 minutes. Do you want to proceed ? YES - NO" This to inform the users how much time they have to wait if they click on Yes.
I checked under the Administrator TAB...but I didn't find nothing "native" about the two questions above.....
So, I ask you if there is a way to activate these features (if they exist "native") or a workaround to implement what I described above.
Any help will be appreciated.
Thanks in advance
Alex

Hi Vetsrini, thanks for your answer.....but what does it mean ? There are no solutions for my requests ? I remember that Discoverer had the possibility to have an alert as I would like to have with BI Publisher and there was the possibility to choose how many rows it was required from the customer....Is it possible that with BIP is not applicable ?
Have a good day
Alex

How can I restrict the number of emails in iOS 7?

In the previous versions of iOS you could indicate how much emails you wanted to store on your iPhone. Now in iOS 7 that option is gone.
I don't want to clogg my iPhone whit all my emails.
What can I do to restrict the number of emails?

Other than changing to an IMAP or Exchange account, you can't. The feature you're referring to was removed in iOS 7.0.
