lr_elem = view->get_element( <ID of the Link to Action field>).
if lr_elem is bound.
view->request_focus_on_view_elem( lr_elem ).
endif.
I am getting "Cannot use NULL reference as object error at view".

Hallo Praveen,
have you controlled that id of the Linktoaction ? there you made error.
See it in the ViewElement designer .
should be something like this
lr_elem = view->get_element( 'LTA_name ' ).

How to set focus on the title of JTabbedPane

I have created a JTabbedPane and added three JPanels to it. They are titled, say "Panel 1", "Panel 2" and "Panel 3". And each of them contains buttons and text areas. Since this app is for physically disabled users, it must provide navigation through these three tabs with keyboard operations only (i.e. without mouse clicks).
When the title "Panel 1" gets focused, users can go to "Panel 2" by the right arrow key. When Panel 2 is brought up, however, the title "Panel 2" does not get focused. Instead the first button inside panel 2 is focused. In order for users to navigate to 'Panel 3" by the arrow key, the title "Panel 2" has to be focused. How do I set focus on the tab title?
I have tried 'requestFocus()' on Panel 2, but it does not work. Please help me with this issue. Thanks in advance.

I'd be quite interested to know if this can be doen as well so I thought I'd post this message to move it to the top of the board.
Thanks.

How to set focus on field having data type other than character(eg. NUMC)

Hello all,
I have developed one screen having table control inside. In table control suppose if numeric type field is blank(eg. Employee number of data type NUMC), system should throw error message and should put cursor focus on that perticular filed. In the same table control for fields of data type 'CHAR', I have done this using 'SET CURSOR FIELD' .
Please, suggest me how to set cursor focus on the fileds of data type other that character(eg. NUMC)

Have you tried it? SET CURSOR FIELD ... works fine for type 'N' fields in a table control. The restriction is 'character-type' and 'flat'. Type 'N' (or NUMC-like) fields are both.

How to set focus on a input field in a selected row of a table?

In a previous discussion (http://scn.sap.com/thread/3564789) I asked how to access an input (sap.m.Input) field of a selected row in a table. In the answer that was supplied I was shown how to get the items of the table. Then using the selected index to get the selected item get the cells. Then I could set editable on the proper cell(s). This worked fine.
Now I need to set the focus on one of the fields. I tried something like this:
            var oNewLink = table.getSelectedItem();
            var oNewLinkName = oNewLink.getCells()[1];
            oNewLinkName.focus();
But this doesn't seem to work.
I have searched through other discussions and have seen this technique for putting focus on a field if you have its ID:
sap.ui.getCore().byId(id_of_the_input_field).$().focus();
In my case though I do not have an ID since the row and its cells are generated. How can I set focus on the cell of a certain row in a table?

Hello Venkatesh. Yes that code does work. First I tried it on a table cell that was already rendered and it did work. The next time I tried it on a table row that was being added and it did not work there. So I added an on after rendering function for the table and added that code there. That did not work until I added a delay (timeout) to do a context switch before calling the focus and that worked.
Once last thing though sometimes when I call focus on an input field (actually in a table row cell) if the field has text in it already the flashing cursor is at the beginning of the text and other times it is at the end of the text (which is the desired way). It depends on where I click in the row. Is there anyway to make sure the flashing cursor is at the end of the text when the focus is applied to a field that contains text?

How to set View for Completed items inside Tasks?

How to set button for 'View' and see Completed items or not completed inside Tasks?

Hi,
You want to set custom views for Tasks folder so that when we click a view button, it will show all Completed or incomplete tasks, am I correct?
Which version of Outlook are you using? There are existing views for completed/incomplete tasks in Outlook. In Outlook 2010 and Outlook 2013, we can find the buttons under View tab > Change View. Click Completed button to view all completed
tasks; Click Active button to view incomplete tasks.
In Outlook 2007, just click View > Current View to switch between different views.
If I've misunderstood something, please feel free to let me know.

Steve Fan

How to set focus in text box at server side

Hi,
I have small problem , i have a text box in form , which is get validated at server side in servlet , if it found some thing wrong then it throws exception , i want that when an exception is thrown it should set focus for that perticular text box. so what should i write to perform such a activity.

Get hold of the element ID in the servlet (and keep the code conventions) and print it out to some Javascript function which does a focus during the onload.
There's an example of focus/highlight using JSP/Servlet/Javascript in this article: [http://balusc.blogspot.com/2008/07/dao-tutorial-use-in-jspservlet.html]. Also see the screenshots at the very bottom.

How programmatically set size of report element in Java

In topic
[How programmaticaly set size of some field?|How programmaticaly set size of some field?]
someone changing programmatically report element, but I think this part of code
is in .NET framework
For example I mean something like following snippet
BoxObject box = (BoxObject) reportClientDocument
.getReportDefController().findObjectByName("headerBox");
BoxObject newBoxObject=new BoxObject(box);
Border border=new Border();
border.setBorderColor(new Color(255,255,255));
newBoxObject.setBorder(border);
newBoxObject.setFillColor(new Color(255,255,255));
reportClientDocument
.getReportDefController().getReportObjectController().modify(box, newBoxObject);
Why I think this is in .NET framework because java object "ReportClientDocument" don't have "getReportDefController()" method (I donu2019t know .NET).
What I want to do, I want to take "Details" (part of report) and change size.
If there is no way to take "Details" how can I take other report element e.g. Text Object

Ernest,
What enviroment are you working in? Because my ReportClientDocument object does have the getReportDefController method. How are you declaring your object?
Try something like:
private static com.crystaldecisions.sdk.occa.report.application.ReportClientDocument myRCD;
BoxObject box = (BoxObject) myRCD.getReportDefController().findObjectByName("headerBox");
Cheers
Darren

How to set focus and mark red on certain select option field

hi experts
I embedded a select_option view in my application and tried to use IF_WD_SELECT_OPTIONS->request_focus to set focus on a certain select option field if the logical check failed, and also hope the low field of the select option can be marked red....but things does not happen that way....
could anyone kindly tell me how to implement that requirement?
tkx and regards
sun

What is the problem you are facing in this ?
Requesting focus is easy.
just call the method request focus and pass the id of the parameter whose lower value field you want to focus.
as shown below.
code you might have written in wddoinit
DATA: LT_RANGE_TABLE TYPE REF TO DATA,
        RT_RANGE_TABLE TYPE REF TO DATA,
        READ_ONLY TYPE ABAP_BOOL,
        TYPENAME TYPE STRING.
    DATA: LR_COMPONENTCONTROLLER TYPE REF TO IG_COMPONENTCONTROLLER,
        L_REF_CMP_USAGE TYPE REF TO IF_WD_COMPONENT_USAGE.
*   * create the used component
L_REF_CMP_USAGE = WD_THIS->WD_CPUSE_SELECT_OPTIONS( ).
IF L_REF_CMP_USAGE->HAS_ACTIVE_COMPONENT( ) IS INITIAL.
    L_REF_CMP_USAGE->CREATE_COMPONENT( ).
ENDIF.
    WD_THIS->M_WD_SELECT_OPTIONS = WD_THIS->WD_CPIFC_SELECT_OPTIONS( ).
    WD_THIS->M_HANDLER = WD_THIS->M_WD_SELECT_OPTIONS->INIT_SELECTION_SCREEN( ).
LT_RANGE_TABLE = WD_THIS->M_HANDLER->CREATE_RANGE_TABLE( I_TYPENAME = 'ZDEALERID' ).
* * add a new field to the selection
WD_THIS->M_HANDLER->ADD_SELECTION_FIELD( I_ID = 'ID'
IT_RESULT = LT_RANGE_TABLE I_READ_ONLY = READ_ONLY ).
code for focusing a field.
wd_this->m_handler->request_focus( i_id = 'ID' ).
you must have declared attributes m_handler and m_wd_select_options type reffering to IF_WD_SELECT_OPTIONS and
IWCI_WDR_SELECT_OPTIONS respectively.
and regarding that red color i am not sure it is possible without using message manager.
thanks

How to set focus on invisible input field?

Hi Guys,
I need an invisible input field and have to set an input focus on it. My problem is that if I set input fields property visible=blank, I get my invisible field BUT the function call doesnt work (setInput.requestFocus()).
I suppose that I cant set a focus if an input field is invisible.
Does somebody know how can I solve my problem? Is there a possibility to do this input field invisible with java script? If yes, how does it work in Web Dynpro?
Thanks
Marita

Hi
Setting a focus on invisible input field will not work even if you follow the method what sowjanya has suggested. The method wdThis.wdGetAPI().requestFocus() will not work for read-only and disabled fields.
By the way why do you want to set the focus on a invisible input field. If you can tell us the requirement maybe we could think of an alternate solution. But i guess for the current scenario setting focus on invisible input field does not work.
regards
ravi

How to set FOCUS on applet (java-plugin)

I wrote applet using Java 1.3.1, using swing clasess.
I use java-plugin, defined in <object ..> and <embed ..> tags as described in documentation,
with MAYSCRIPT parameter and ID and NAME parameters defined.
How to set up focus on this applet through JavaScript?
I have tried:
document.embeds[0].focus()
document.applets.MyApplet.focus()
document.objects.MyApplet.focus()
document.objects[0].focus()
document.MyApplet.focus()
But nothing works in my IE5.x or NC4.7. Applet itself works fine.
Is some special methods need to be defined in JApplet to catch the focus?
Thanks for any advice.

Thanks for any advice.With IE you should try the following:
<OBJECT id='MyApplet' ...
document.MyApplet.requestFocus();
This worked fine for me, even without specifying additional "MAYSCRIPT" or "scriptable=true" tags. Obviously this construct managed to call the public Java method "requestFocus()" from JavaScript.
Maybe something similar would also work for Netscape. I felt no need to do this when running in Netscape, because the Netscape browser handled focus management without problems.
For IE I tried to workaround a problem mentioned by several people in this forum: The focus will not be regained by an applet when the user switched form IE to another application and then returns back to the browser window which contains the applet.
Unfortunally the following code fragment worked only partially well:
function activated()
if (isIE)
document.MyApplet.requestFocus();
return true;
window.onfocus = activated();
OnFocus is invoked only each second time when the browser window gains back focus.
I'm still looking for a real solution, so I'd appreciate if anybody could come up with one.
Hope this helps a bit
