How to add a blank entr in dropdown list...??

Hi all,

Can anyone please sugeest how to do this task.
Thanks in advance,
Sekhar

Hi,
I think the blank value in a filter is same as showing All, and not only the rows which has value blank. Nevertheless both can be achieved as below.
"Blank Value to show everything in Table as if no filter provided"
value-key = '*'.
value-value = 'All'.             " This will show up the text as All and work as if no filter is given and it will show all.
APPEND value to set.
"Blank Value to show the rows which has the value as space"
value-key = space.
value-value = 'None'.             " This will show up the text as None and work as if filter is given to show value as space
APPEND value to set.
Hope this help!
Regards
Vineet

  • How to add first blank entry in messageChoice

    I have a messageChoice that's populated entirely from the associated model (which happens to be a backing view/sql table). The only items that show in the list are populated records from my view/table. This is sufficient for create / edit forms, where I must have a value for the field that this messageChoice binds to. But it is problematic on the UIX Search Form component, because I need a blank entry in my messageChoice, so if the user creates new search criteria, it doesn't automatically take the first value in the list as part of the filter.
    How can I add a blank first option in my messageChoice when the messageChoice is bound to a model backed by a view?
    Thanks.

  • Disorganized forums (with bonus of how to add a blank page in acrobat)

    Gee wiz these forums are disorganized.
    Hey adobe, want to see how a forum should be organized? Then go to any of the bazillion websites that are set up on a hierarchy and EASILY searchable within a topic, instead of the convoluted mess that you have here.
    Here is another answer to "how to a add a blank page" to a doc in acrobat.
    Since it has already been "answered" (how absurd is that) I am posting it here, in hope that someone can find it because THIS solution is no where else on the web as far as i can tell.
    Option click & drag a page to duplicate it then delete the page contents with the “touch up object” tool. then duplicate the page to your hearts content. note you will need to remove password if any first.
    .

    I've been usin acrobat since Version 4. Currently have last updated version 9.
    Just recently made some pdfs. The last time I did a multipage PDF has been a while (but still after version 9).
    But in order to see a full 8.5x11 page I had to do the dot trick I spoke of, there has to be some type of content even if same color as background, more than halfway down the page in order for it to show as a full page, you do nothing if it even creates one, shows as a half page or less.
    And if you want it to look professional, you type either in middle or just bellow middle, the words:
    THIS PAGE INTENTIONALLY LEFT BLANK
    set color to a pale gray (as shown above). I've seen PDF Manual for software using this.

    Why do you need the extra space for?
    This difference in display that you see between your browser and notepad/notepad++

  • How to add items dynamically to the DropDown Ring control in Web UI Builder

    Hi All,
    Is there any way to add the item names to DropDown Ring Control in Web UI Builder?
    Or
    Is there any other control available to make selection in the Front Panel which can be dynamically loaded?
    Thanks,
    Alagar

    DiyaDiya  
    We do not currently have a solution for populating the items in a ring dynamically. 
    Thanks for the clarification.
    Seems incredible after all these years that such functionality (dynamically populating a ring control) is still beyond Labview. I must be missing something.
    However, I'd suggest a combobox is closer than a listbox as a workaround.
    [edit]
    nevermind, it actually can be done (well, maybe not in the webUI), I found the explanation here http://digital.ni.com/public.nsf/allkb/FB0409491FAB16FA86256D08004FCE7E

  • Blank line in DropDown List box

    I have a case where I want to add a blank entry in a drop down list box that is bound to a database table. I want the blank to be the default, then the user can select the bound values if desired. How do I do this without binding the drop down box to a prepopulated array?

    Hi
    Go to the JSP source of that page and add
    <f:selectItem itemLabel="None" itemValue="0"/> before
    the line <f:selectItems binding="#{Page1.dropdown1SelectItems}" ....
    With this you can deselect the previous selection by selecting None from the dropdown list. You can also use blank spaces instead of None.
    Thanks

  • How to add a Field to the Result List in Activity

    Hello Experts !
    We are on CRM 7.0. I want to add a field to the Result List of Activity (Component: BT126S_APPT / View: ApptSR). This field is the address of the "Employee Responsible".
    So, how can I add a field to the Result List? AET is not a relevant tool for us because we don't want to create an attribute it already exist in the BOL. We just have to enhance the result list with BOL existing attributes.
    Also, after I add the field, I will need to populate my field with Data via some method.
    Thanks in Advance to all !

  • How to set a default value in dropdown list in Wendynpro ABAP? Help!

    Hi Experts,
           I have Webdynpro for ABAP application that shows a DropdownwithKey UI element.
    1. I am able to populate the dropdown list. But by default the list is not showing any value. Only when I select a value from the list then it shows it.
    So how to set the default value to the first value in the list? Any code sample will be really helpfull.
    I have written the following code:
    method WDDOINIT .
      DATA:
        node_category TYPE REF TO if_wd_context_node_info.
      node_category = WD_CONTEXT->GET_NODE_INFO( ).
      node_category = node_category->GET_CHILD_NODE( 'CATEGORY' ).
      data:    LT_VALUESET type WDR_CONTEXT_ATTR_VALUE_LIST,
               L_VALUE type WDR_CONTEXT_ATTR_VALUE.
    L_VALUE-VALUE      = 'V1'.
    L_VALUE-TEXT    = 'yesterday'.
    INSERT L_VALUE into table LT_VALUESET.
    L_VALUE-VALUE      = 'V2'.
    L_VALUE-TEXT    = 'today'.
    INSERT L_VALUE into table LT_VALUESET.
    L_VALUE-VALUE      = 'V3'.
    L_VALUE-TEXT    = 'tomorrow'.
    INSERT L_VALUE into table LT_VALUESET.
    node_category->SET_ATTRIBUTE_VALUE_SET(
                 NAME = 'CAT_VALUE'
                 VALUE_SET = LT_VALUESET ).
    endmethod.
    Note that: I am using webdynpro for ABAP.
    Thanks
    Gopal

    I am not sure how it works in Web Dynpro for ABAP, but in Web Dynpro for Java 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>(<defalut value>)
    This generally done in Initialization method of the controller.

  • How to add new data element to field list

    Hi,
    I am implementing Succession Planning 3.0 SP1.
    To make new data element was successful.
    I want to use them as sort field, however I don't know how to add them to the list of fields with caption.
    (i.e. to setting Visualize>My Org Units>Sort Fields)
    If you know how to config data elements usw. Please advise.
    Best Regards,
    Hiroshi Takimoto

    Hi Hiroshi,
    There are 2 ways to do this, both involving some customization of the application.
    1) Extend your HR-OCI views (TMC_O_SUCC_T & TMC_O_SUCC_B for My Org Units and TMC_IN_REP_T_DT & TMC_IN_REP_B_DT) to include Short Name. You probalby want to seek help from an OM consultant if this is not your area of expertise.
    2) Create a linked data element that links together the existing data elements and a new data element which includes Short Name. Your new data element must have the name of the existing data elements or you should change the hierarchy configuration that uses these data elements. Beware that this can prove troublesome for the Position Hierarchy because of the "virtual root" that is created - sometimes the join does not work because of this.
    Best regards,
    Luke

    Maybe you actually have null entries in your list. You can clean it up using keys as discussed here http://paranoid-engineering.blogspot.in/2008/05/wonderland-of-oracle-forms-builder.html (Ignore the personal opinions of the author if you will ;) ).
