Extra Row in Combo Box

hi:
When I make a list item a Poplist style it adds another null row to the list. When I change the from poplist to a combo list I get the correct number of items.
For some reason an extra 'null' entry is added when the list is a Poplist ?
Does anyone know what is causing this ?
Thanks,
Deepak/

yes, I have been thinking it's Oracle's masterpiece jewry of the crown feature, if you complain it, that means you don't know how to appreciate it; if Oracle does not appreciate it as you, then it may have been fixed it in forms6.0/6i or even 5.0.

Change table rows with Combo Box

I want to change the size of the rows displayed per page. I tested this code but the number of the rows is updated only when the pages are switched. Can you tell me how I can fix this?

Populating Combo Box list value In Multiple Row

Hi,

I have used add_list_element to populate the list value of the combo box in multiple row.
I am selecting the list value from the database where the combo box value will be different for each row. However, when i do this.
All the previous row combo box list value will follow the combo box value in the last row. How can i resolve this?
i tried with lov but hasnt had any sucesss.in case of LOV can we make the list to appear automatuically and select a value????i havent had much sucesss over it??
is thr any work around for this apart from lov?

Increasing row capacity of any excelcius component (Filter ,Combo Box)

Hi
Even though I have increased the capacity of Dashboard rows capacity from 512 to 2000.
But my filter component or combo box component source data is mapped to more than 512 rows in the spreadsheet,while previewing it still shows data of 512 rows.
Is there any way to increase component capability?
I know the performance will be bad but still atleast it should capture the whole source data records and

It could be two reasons
First Reason: it could be due to the limit of no of rows in excel .Please check the preferences option in Xcelsius . By default it will be set as 512 rows of data increase that to required rows.
 Second Reason: if you are using live office in Xcelsius.By default it will fetch 512 rows of data.To increase limit we have to do some server side settings.Please refer to the following SAP Note which gives the solution to this problem.
SAP Note:1307538
or go through the following steps:
These changes have to be made on the server side
1. Create a backup of dsws-liveoffice-provider.jar from serveru2019s InstallDrive:\program files\business objects\Tomcat\webapps\dswsbobje\WEB-INF\lib for future reference.
2. Copy dsws-liveoffice-provider.jar from serveru2019s InstallDrive:\program files\business objects\Tomcat\webapps\dswsbobje\WEB-INF\lib to your computer.
3. Rename the file just copied to dsws-liveoffice-provider.jar.zip (add.zip to end of filename)
4. Create folder in root of InstallDrive: named META-INF (case sensitive), in InstallDrive:\META-INF named BusinessObjects (case sensitive) and in InstallDrive:\META-INF\BusinessObjects named DSWS (case sensitive)
5. Using WinZip or WinRAR, unzip the file named liveoffice_config.properties from the dsws-liveoffice-ws.jar.zip file copied from the server. Place this file in InstallDrive:\META-INF\BusinessObjects\DSWS.
6. Edit the liveoffice_config.properties file and find the following section:
#max number of range rows and range columns to return
maxRowCount=512
maxColumnCount=512
7. Edit the maxRowCount entry to the value youu2019d like to use
8. Save the file as liveoffice_config.properties (same filename)
9. Using winRAR or WinZip add the new liveoffice_config.properties file back to dsws-liveoffice-ws.jar.zip, making sure to use the "use absolute path" option.
10. Stop Apache Tomcat service on BO server
11. Copy dsws-liveoffice-ws.jar.zip to serveru2019s InstallDrive:\program files\business objects\Tomcat\webapps\dswsbobje\WEB-INF\lib.
12. Rename dsws-liveoffice-provider.jar in serveru2019s InstallDrive:\program files\business objects\Tomcat\webapps\dswsbobje\WEB-INF\lib directory to dsws-liveoffice-provider.jar.old.
13. Rename dsws-liveoffice-provider.jar.zip in serveru2019s c:\program files\business objects\Tomcat\webapps\dswsbobje\WEB-INF\lib directory to dsws-liveoffice-provider.jar
14. Empty the Tomcat cache by deleting the content of the folder <<C:\Program Files\Business Objects\Tomcat55\work>>
15. Restart Apache Tomcat on server
This should increase the number of rows fetched by LiveOffice, however it may happen that changing the number of rows in the liveoffice_config.properties many times may result in liveoffice picking the data from the cache. Hence deleting the cache (C:\Program Files\Business Objects\Tomcat55\work) is necessary. Incase deleting the cache also doesn't work, we may have to redeploy the dswsbobje folder.
To redeploy, follow the steps given below:
1. Go to C:\Program Files\Business Objects\Tomcat55\webapps and keep a backup of the dswsbobje folder.
2. Now delete this folder and restart Tomcat.
3. Restarting Tomcat will recreate the dswsbobje folder but will again default the number of rows fetched by LiveOffice to 512.
4. We will again have to follow the steps mentioned in the start to increase the number of rows from 512 to the desired value.
5. Restart Tomcat again for the changes to take place.
Note: Increasing the number to large values might cause inconsistency in the behavior or instability.

How to display "All Items" using a "Filtered Rows" Combo Box

Hi
How do I make a Combo Box with "Filtered Rows" show "All Values" by default, AND have the option to select individual filters?
If my data was
North
South
East
West
I would want the Combo box to display
ALL
North
South
East
West
When the user selected:
North, they should see just the filtered rows with North
South, they should see just the filtered rows with South
ALL should be the default, and it should ifilter/include North, Soutn, East and West (i.e. showing all the rows)
I need to use a Combo box and Filtered Rows, because I actually want to filter my dataset using multiple columns:
Company, Region, District, Sector, Value
My current method is to:
use a Combo to filter the RawData on Company into an Intermediate_Company worksheet
use another Combo to filter the Intermediate_Company worksheet on Region into an Intermediate_Region worksheet
use another Combo to filter the Intermediate_Region worksheet on District into an Intermediate_District worksheet
use another Combo to filter the Intermediate_District worksheet on Sector into an Intermediate_Sector worksheet
then display in a List View from the Intermediate_Sector worksheet.
Any comments on this method would also be welcome.
Thanks for your help
Stuart

Thanks Muwa
I've uploaded a non-working version here: http://www.teradepot.com/ntxgoo6629zi/Simple_All_Combo.xlf.html
I've figured out how to use tthe filter to copy a subset of the rows in the source date to the destination are of the worksheet.
I can't figure out how to use a filter to copy ALL the rows in the source to the destination.
I've seen hints about using hidden filters, but I can't make this work, either. It's quite depressing, really
I'm very grateful for any help you can give.
Thanks in advance

Combo box restricted to 516 rows

Hi,
I have data upto 1000 rows which i need to feed to a combo box. But the max limit a combo box takes is 516 rows only.
Is there any work around for this?
Regards,
Jith

The data i have is names of clients. I have one combo box with labels of starting letter example A, B, C, etc to Z. The insertion type is Filtered Rows. Now Source data is the whole 1800 rows. The destination rows are the labels for the second combo box.
Data is like this:
Col1 Col2
A      Anand
A      Arpan
A      Anil
Z      Zebra
Like this i have total of 1800 rows.
I went to file preferences and in excel options i have changed to 1800 rows. It looks ok BUT, If i try to preview it, it just hangs. And if i try to export it into a flash file it just shows the top 512 rows, it is not showing the whole 1800 rows.
Thanks For your help. Any Ideas how to deal with this large data?
Regards
Jith

Adding an event listener to combo box

I am working on a mortgage calculator and I cannot figure out how to add an event listener to a combo box.
I want to get the mortgage term and interest rate to calucate the mortgage using the combo cox. Here is my program.
Modify the mortgage program to allow the user to input the amount of a mortgage
and then select from a menu of mortgage loans: 7 year at 5.35%, 15 year at 5.50%, and
30 year at 5.75%. Use an array for the different loans. Display the mortgage payment
amount. Then, list the loan balance and interest paid for each payment over the term
of the loan. Allow the user to loop back and enter a new amount and make a new
selection, with resulting new values. Allow user to exit if running as an application
(can't do that for an applet though).

The OP already did this to both JComboBoxes.
mochatay, here is a new actionPerformed method for you to use.
I've improved a few things here and there...
1) You can't just cast the ActionEvent's source into a JComboBox!
What if it was a JButton that fired the event? Then you would get ClassCastExceptions (I'm sure you did)
So check for all options, what the source of the ActionEvent actually was...
2) You can't assume the user will always type in valid data.
So enclose the Integer and Double parse methods in try-catch brakcets.
Then you can do something when you know that the user has entered invalid input
(like tell him/her what a clumsy idiot they are !)
3) As soon as user presses an item in any JComboBox, just re-calculate.
I did this here by programmatically clicking the 'Calculate' button.
Alternatively, you could have a 'calculate' method, which does everything inside the
if(command==calculateButton) if-block.
This will be called when:
a)calculateButton is pressed
b)when either of the JComboBoxes are pressed.
public void actionPerformed (ActionEvent event)
        Object command = event.getSource ();
        if (command == calculateButton) //calculates mortgage payment
            int year = 0;
            double rate = 0;
            double mortgage = 0;
            double interest = 0;
            /* If user has input invalid data, tell him so
            and return (Exit from this method back to where we were before */
            try
                year = Integer.parseInt (mortgageTerm.getSelectedItem ().toString ());
                rate = new Double (interestRate.getSelectedItem ().toString ()).doubleValue ();
                mortgage = new Double (mortgageAmount.getText ()).doubleValue ();
                interest = rate / 100.0 / 12.0;

Difference between Combo Box and Dropdown List

Hi All,
I would like to know the difference between the elements 'Combo box' and 'Dropdown List' in VC. I am facing an issue where i am invoking an entry list and the output of the first element the entry list returns is getting reflected as the output for all the elements...
So even if 2nd and 3rd row of the o/p from the entry list is giving only 2 items, if the 1st row returns only 1 then we are able to see only 1 item. Its as if the 1st row decides the items to be returned for all the rows.
Please help.

Hi Hezi,
I have 2 columns in my table. First column is 'material number' and the 2nd one is 'production version'. There can 1,2 or 3 production version for each material. [This information is stored in the backend] This is retrieved through a method which invokes a bapi which in turn retrieves from the backend.
I have provided a dropdown list for the 'production version' column. Lets say there are 2 rows. Material 1 and material 2. Lets say material 1 has 1 production version and material 2 has 2 production version. So rightfully speaking i should have 1 option in the dropdown for material 1 and 2 for material 2.
But what i seeing is only 1 option for both the materials. This is wrong.
Is there something that can be done to ensure that each row reflects the correct no. of options in the dropdown?

How to change screen combo box value from a method?

Hi,
I have a screen that has a combo box and an ALV.
the combo box has the line numbers of the data in the ALV.
you can select the line item and then the ALV changes...
I fill the combo with function VRM_SET_VALUE.
all is good once the user changes the combo box.
I want to enable the user to click (hotspot) on ALV and then to ... and to change the value of the combo box to the line number he clicked on.
I couldn't change the value inside that box.
The combo box is declared as global parameter.
when I assign a value to it inside the method, it is good. but once back to PAI, it is the old value.
Do you have any idea how to set up that value?
Thanks.

Itay,
When you load the combo box, you should be setting a "key" for each entry in the combo box.
See below:
move '2010FY' to Value-Key.
move '2010 - Full Year' to Value-Text.
append value to list.
move '2010Q1' to Value-Key.
move '2010 - Q1' to Value-Text.
append value to list.
move '2010Q2' to Value-Key.
move '2010 - Q2' to Value-Text.
append value to list.
move '2010Q3' to Value-Key.
move '2010 - Q3' to Value-Text.
append value to list.
move '2010Q4' to Value-Key.
move '2010 - Q4' to Value-Text.
append value to list.
move 'COMBO1' to name. "name of Combo box in the screen
call function 'VRM_SET_VALUES'
    exporting
      id = name
      values = list.
So add these "keys" to a hidden column in the ALV grid. Then .... when the user presses a hotspot, pass the value of the hidden column (for the selected row) into the COMBO1 box.
move '2010'FY' into Combo1. " if they selected Full Year of 2010

How to use the Combo Box In MAtrix Colums

HI Experts,
Good Mornong.How to use the Combo Box In MAtrix Colums?
Regards And Thanks,
M.Thippa Reddy

hi,
loading data in to the combobox on form load.but, it should be done when atleast one row is active.
the values what ever you are inserting in to combo should be less than or eqhal to 100 or 150.if it exceeds beyond that performance issue arises.it takes more time to load all the data.so, it is better to have 100 or less.
oMatrix.AddRow()
RS = Nothing
RS = ocompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.BoRecordset)
RS.DoQuery("select ItemCode,ItemName from oitm")
oCombo = oMatrix.Columns.Item("ColumnUID").Cells.Item(oMatrix.RowCount).Specific
For i = 1 To RS.RecordCount
      If RS.EoF = False Then
            oCombo.ValidValues.Add(RS.Fields.Item("ItemCode").Value,RS.Fields.Item("ItemName").Value)
            RS.MoveNext()
      End If
Next
the above code is inserting data from database to column combobox.
you can fill combo directly also as shown below.
oCombo.ValidValues.Add("x","1")
oCombo.ValidValues.Add("y","2")
oCombo.ValidValues.Add("z","3")
oCombo.ValidValues.Add("","")
and what ever the values you are filling into combo should be unique.other wise it shows valid value exists.

Control the combo box select of COPY FROM in Delivery Order

Dear all
I have a requirement where in the user wants to restrict the "copy from" button on the delivery order. They want the delivery orders to be created only from Sales orders.
So that would mean that i do a bubbleevent = false when any other row is selected in the combo box dropdown. But I am not able to get the control to the combobox.
In the system information it says that the form is "-9876", but couldnt catch any event on it either.
Any suggestions to control the selection of the "COPY FROM" combobox is most welcome.
Thanks in advance
Rashmi

Hi Use This Ihave Checked This
If pVal.Before_Action Then

                    If pVal.ItemUID = "10000330" Then
                        If pVal.PopUpIndicator = "2" Then
                            objAddOn.objApplication.SetStatusBarMessage("You Can Not Copy From Returns")
                            BubbleEvent = False
                            Exit Sub

How to fetch records from the database into a combo box?

Hi:
I´m really new with ABLBPM and I´m trying to fetch records from the database to display them into a combo box as valid values for a presentation but I´m using a dynamic method with this code:
for each row in SELECT campo1, campo2 from TABLE
do
solicitudes[] = [row.campo1, row.campo2]
end
return solicitudes
And the debugger says that SQL instructions can be used only in fuctions and procedures that are executed on the server.
Do you know another way to do it?
P.D. Sorry for my terrible english
Greetings

Hi Steve,
Thank you, your idea is perfect, but when I try to run the screenflow where the combo should be filled I get this error:

How do I retrieve data from combo boxes?

The past weekend I spent my whole weekend trying to find this
out and gone through the top 10 pages on google trying all sorts of
things. I would be grateful for anyone who can help me.
I have 6 combo boxes in a booking form and I need to retrieve
the data when someone click submits which gets forwarded on to php
then my mailbox. They are called box1_cb, box2_cb.....box6_cb All
in the instance of: ComboBox - which I don't understand what that
does.
it does not seem to be retrieving any of the data. For each
combo box:
I have the the options people can choose form in "Labels" box
under "Paramaters", nothing for "Data", Row Count is 8 and nothing
for "Change Handler" which I don't know what it does.
Can anyone please provide some help with telling me what
"change handler" does, do I need the data for each combo box in the
"Labels" parameter as well as the "Data" box, what an instance does
(for combo boxes) and what I need to put in the actionscript for
the submit button as well as do i need to put code in the
actionscript for each combo box?
The options people can choose from in the combo boxes are
there when someone views the site.
Can anyone please help me..I would greatly appriciate it.
Thanks.

If your hard drive can be detected and shows up as a drive letter in my computer but you can't access your files,then you can recover your data off it with data recovery software easily.This way is the easiest and the most inexpensive way to recover your data.If you bring it to a computer repair shop that is available for data recovery servise,they will cost you $500-1000 or more.Hmm, a lot of money.
I managed to recover data from crashed hard drive with Tenorshare Data Recovery.If needed,you can download it and scan your hard drive for free to preview whether your data can be recovered.It will show you thumbnails for recoverable pictures.

07-04-10 | 07-04-10 | b | $9,875
08-06-10 | 08-06-10 | a | $9,875
