Dropdown in column group of a table

I am building a table with one multiple column groups, each has a number of columns, one of these columns have a dropdownbykey field. I get a ClassCastException on this. It seems like there is a bug in the implementation, because when I move the dropdown out of the column group it works fine.
Regards
Juan

How is the "selectedKey" property of the dropdown-list bound
You need to bind the property "selectedKey" for the DropdownByKey UIElement

SQL Modeler : Column Groups

Is the Column Group option (under Table Properties) not yet implemented?
It does not seem to save a column group and the topic is skipped in the Help File for the Table Properties topic.
Edited by: user635766 on Jul 9, 2009 6:08 AM

Hello,
thanks for feedback. I checked it - you can add groups, change columns belonging to them and they are saved. Unfortunately group cannot be deleted and change in the name of the group is not applied if press OK while in editing mode.
I logged bugs for these problems.

Setting the header of a Column group in a Advanced table dynamically

Hi All,
There is a requirement to set the Header of a column group in a Advanced table dynamically by fetching the values from a view attribute.
Code :
OAAdvancedTableBean spiderTbl1 ;
Problem:
It is not able to set the value for the header inspite of getting the handle of the bean.
Analysis:
the same piece of code works for
1) Setting the text of the advanced table
2) Setting the header of a column in a column group
Please let me know if there is anything more that needs to be done for setting the prompt of a column group header.
Thanks in advance!

I have posted it without giving the complete code by mistake. Below is the code:
OAAdvancedTableBean spiderTbl1 ;
OASortableHeaderBean spiderHdr1;
spiderTbl1 = (OAAdvancedTableBean)webBean.findChildRecursive("SpiderCatTbl1RN");
if (spiderTbl1!=null){
spiderHdr1= (OASortableHeaderBean)spiderTbl1.findChildRecursive("AnalogHdr");
if (spiderHdr1!=null) {
spiderHdr1.setAttributeValue(OAWebBeanConstants.PROMPT_ATTR,
new OADataBoundValueViewObject(spiderHdr1,
"SpiderCategory1",
"ProjRegPVO1"));
}

How can I do a Header Group Using Group columns for WD ALV tables

Hi
I want to group columns into a header group.
Eg:
from Date
Availability
to date
Any ideas if it is possible with WD ALV tables?

Hi,
Try to use the if_salv_wd_field_settings for the column grouping of the Model object.
Also check the class CL_SALV_WD_FIELD.

Table with column group (one column) - next row is showing on new page instead of below previous row

I am creating new table. My goal is to display some text in few lines like this:
"AAAAAAAA" "BBBBBBBB" "CCCCCCCCC"
"DDDDDDD" "EEEEEEEE"
Actually the next row (with "DD" and "EE" values) is not displayed below first row, but on the next page.
I've tried to put table into rectangle, disabled all page breaks and still the same effect. Any help?

Hi Heidi,
Actually, it's not solution, I only gave more details about my problem :)
Another description:
In my report I'm creating Tablix with Column grouping. There is only one column with image (every image has same width). If there is only three pictures, then they are displayed next to each other in one row.
In case, there is more than three pics, another row is showing on next page. I'd like to display all rows one after another on one page.
I've tried to create three vertical lists, and filter each column group to display only records:
1) =(RowNumber("Tablix1")) mod 3 = 1
2) =(RowNumber("Tablix1")) mod 3 = 2
3) =(RowNumber("Tablix1")) mod 3 = 0
Unfortunately, I got an error:
"A FilterExpression for the tablix ‘Tablix1’ uses the function RowNumber. RowNumber cannot be used in filters."
Do You have any other propositions?
--------EDIT--------
ok, I manged to solve it. As I said, I've created three vertival lists and placed them next to each other.
Then, instead of using filter, I've used Visibility trigger:
1)
=IIf(RunningValue(Fields![rowgroupfield].Value, COUNTDISTINCT, "Tablix1") mod 3 = 1, false, true)
2)
=IIf(RunningValue(Fields![rowgroupfield].Value, COUNTDISTINCT, "Tablix2") mod 3 = 2, false, true)
3)
=IIf(RunningValue(Fields![rowgroupfield].Value, COUNTDISTINCT, "Tablix3") mod 3 = 0, false, true)
I had to use function RunningValue to count all occurrences, as my report is quite complex and "RowNumber" [ssrs function] and "ROW_NUMBER() OVER (ORDER BY [rowgroupfield])" [sql query] were not working properly.

ALV with dropdown in column and other questions

hi,
I created an editable alv with configuration model via external context mapping.
now I have a column which contains strings and my aim is to show this whole column as a dropdownlist. the possible values of this dropdown are fetched in a database table at runtime and each cell in this column got its own selected value in this dropdownlist.
changes of the selected values should be written in the database table in a later step.
1. what changes do I have to do?
should I remove my external mapping concerning the alv and use the setData method? or what is the easiest way to get my dropdownlist in this column instead of normal text (string) ?
2. should I choose dropdownbykey or by index?
   I suppose I have to change the context when changing the selected value in the dropdownlist and the read out the changed context element and update my database table?
3. how could I access rows (= tuples) in an alv?
4. how can I avoid that a row could be deleted, inserted or added with the normal functions of the alv?

Hi Thorsten,
If the possible list of values in the dropdown is different for each row, you need a drop down by index. Else this can be done using a dropdown by key itself.
The only change that you need to do is create a cell editor of type dropdown for that particular column and configure your ALV model.
The sample code for changing the cell editor would be:
    l_alv_model = l_ref_interfacecontroller->get_model( ).
DATA:
     lr_column_settings TYPE REF TO if_salv_wd_column_settings,
     lr_column type ref to CL_SALV_WD_COLUMN.
     lr_dropdown TYPE REF TO CL_SALV_WD_UIE_DROPDOWN_BY_KEY.
lr_column_settings ?= l_alv_model.
lr_column = lr_column_settings->get_column( <column name> ).
CREATE OBJECT lr_dropdown EXPORTING
SELECTED_KEY_FIELDNAME= '<fieldname>'
lr_column->set_cell_editor( lr_dropdown ).
Here, you can substitute the field name with your field name that has to be displayed as a dropdown.
The dropdown list can be populated in the wddoinit method by attaching a value set to the attribute in the context node info. Everything else will be like you do in a normal table. You can so a get_static_attributes of your elements and persist in tables. Whenever you change the selected value, the context will be updated immediately. You can have a user defined function like 'Save' or something where you can just read the context and process the data.
If you do not want to display any of the normal functions, you can do the following:
data: lt_functions type SALV_WD_T_FUNCTION_STD_REF,
        ls_function type SALV_WD_s_FUNCTION_STD_REF.
lt_functions = l_alv_model->if_salv_wd_function_settings~get_functions_std( ).
loop at lt_functions into ls_function.
ls_function-r_function->set_visible( CL_WD_UIELEMENT=>E_VISIBLE-NONE ).
endloop.
The above code will hide all the standard functions. If you want to hide specific ones, do a get_function(id) and set_visible.
Hope this helps.

How to create RunningValue Through Column Groups?

Hi Everybody i´m trying to do this with a Matrix
I want the running value of the product quantity for each month of a year,
resetting the running value
when a new year is reached
I have 2 column groups "Year" and as it´s child group "Month".
                     2009
2010
                     January Febrary March      January   February March
Product
Toolbelt            10           15       20
1            10            50
Well that is the idea...
In the field of the quantity i´m using an expression like this = RunningValue(Fields!Quantity.Value, Sum, Nothing) .
With this expression i get the the running value and it´s great, but
it does not reset thru the years ,
it continues aggregating the quantity value.
So i tried with this expression assuming if i set the SCOPE to the Year group i can achieve this
= RunningValue(Fields!Quantity.Value, Sum, "Year") ,
But surprise!!, this is not giving me the right aggregation , i´m still dig in it and can´t find what it actually aggregates.
Am I doing something wrong?.
All the help is welcome. Thanks.

Hi UzielB,
Based on your information, I get your requirement completely, here you want to accumulate the value of month from
Jan to March whin one year, then return to Jan again whin another year. If I misunderstand you please do not hesitate to let me know.
Now the issue you are encountering is that the value does not reset through the different years.
Actually, nomatter it is 2009 or 2010, RunningValue function takes different years as the same scope, so the value does not reset
through the different years. Just like picture3.
To workaround the issue, we might need to utilize the subreport in the main report, for detailed steps please follow
these:
1.
Design the subreport with two column groups
Year, Month and one row group Product.
2.
Type in the expression in the data textbox
=RunningValue(Fields!Yourdatafield.Value,sum,"Product") Here
Product is the row group name.
3.
Add one parameter
Year to the subreport, of course you should add the parameter year behind the where clause in the T-sql. Such as
select * from yourtable where Year=@Year
4.
Delete the
Year column and Product column, here please make sure you just delete the column only rather than deleting the relevant reportitem.
5.
Decrease the height and width of the report to the report control size, then there is no blank space when displayed in the main report.
6.
Drag a matrix to the main report, just add one column group
Year.
7.
Then drag a subreport control into the data textbox, and then rigth-click the subreport control->select subreport
properties
8.
In the Subreport Properties dialogbox, please selec the subreport name in the drop-down list of
Use this report as a subreport
9.
Swith to
Parameter tab, click Add button to add a parameter, then select the
Year in the Name drop-down list and
Year datafield in the Value drop-down list.
10.
Click OK.
11.
Now add another table control into the
main report body with one column, and drag the product datafiled into the data textbox. Then group the table by
Product.
12.
Drag this table into the
Rows textbox of the main report. Here make sure the height of the rows in Subreport and table creted in step11 is the same, otherwise the lines in not stay in the same level.
Preview the report, you will see the report like picture2.
If you have any question about the steps, please feel free to ask.
Have a wonderful day

How to sum different column in the same table

Hi everyone
I would like to know how can I make the sum of different column in the same table using apex
exple:
TR_PROJ_BIL_TRIM.ENTPIDFISC as ENTPIDFISC,
    TR_PROJ_BIL_TRIM.EXEANNEE as EXEANNEE,
    TR_PROJ_BIL_TRIM.PROJBILTRIMT1PREV as PROJBILTRIMT1PREV,
    TR_PROJ_BIL_TRIM.PROJBILTRIMT2PREV as PROJBILTRIMT2PREV,
    trunc( TR_PROJ_BIL_TRIM.PROJBILTRIMT1PREV)+(TR_PROJ_BIL_TRIM.PROJBILTRIMT2PREV)
from TR_PROJ_BIL_TRIM TR_PROJ_BIL_TRIM
group by TR_PROJ_BIL_TRIM.ENTPIDFISC,TR_PROJ_BIL_TRIM.EXEANNEE
but while trying to run this script i get this error message:"ORA-00979: not a GROUP BY expression"
thanks for reading me and I hope to hear from you soon

Hi,
Your question do not have anything do with APEX.
It is pure SQL question and you will get better answer this kind questions from SQL and PL/SQL forum
You need have GROUP BY when you use aggregate functions like SUM.
I assume you like just add two columns.
Try
SELECT ENTPIDFISC
    ,EXEANNEE
    ,PROJBILTRIMT1PREV
    ,PROJBILTRIMT2PREV
    ,trunc(PROJBILTRIMT1PREV) + (PROJBILTRIMT2PREV)
FROM TR_PROJ_BIL_TRIM

How do I restore column headings in Response table after accidently deleting them? Undo doesn't work.

How do I restore column headings in Response table after accidently deleting them? Undo doesn't work (only seems to go back one level). I also have so many headings I won't be able to type them in manually!

With the help of information from user, ptressel, in [https://support.mozilla.org/en-US/questions/1032154#answer-673322 a post here about the existence of sessionstore.js when version 33 was released], I was able to easily recover my tabs and tab groups as follows:
# close Firefox and, perhaps, allow a few seconds (30s?) for any final closing of files;
# check to see if you have a sessionstore.js file in your profile folder, named like the one I documented in my original post above;
# if it is not timestamped prior to the discovery of your problem, open the sessionstore-backups folder;
# check if the recovery.js file is suitably timestamped and, if not, the recovery.bak.
# At this point, you are likely to find that none of them are prior to your problem occuring. If so, open your backups of this folder and go through steps 2-4 to find a file prior to your problem occuring.
# When you find a file, copy it to the root of your current profile folder and name it, "sessionstore.js"
# Open Firefox. Mine opened up as desired.
This is a Windows solution. Sorry I can't comment on other platforms, but I'd bet that as this is just a file copy and renaming, it is likely the same.
For Windows users, you may find you need to sign out and login as an administrator in order to access the backups. You need not logoff your standard account, but do have Firefox closed as described above.
Hope that helps.

How to get the difference between two columns in a column group

Hi All,
My first time here and really new to programming. I would like to get the difference between 2 columns that are inside
a column group.
Here is my sample table below: The Column Group is PeriodNumber and can only choose 2. like 1 and 2.. I would like to have a third row which will simply calculate the difference between the amounts in PeriodNumber 1 and 2.
PeriodNumber
Account 1 2
1) Cash 10,000 15,000
2) Receivables 12,000 11,500
3) Equipment 5,000 5,500
Total Assets 27,000 32,000

Hi yabgestopa,
From your description, you want to get the difference between two columns in a column group. After testing it in my environment, we can use custom code to achieve your requirement. For more details, you can refer to the following steps:
Copy the custom code below and paste it to your report. (Right-click report>Report Properties>Code)
Dim Shared Num1 As Integer
Dim shared Num2 As Integer
Public Function GetAmount(Amount as Integer, Type as String)
If Type = "1" Then
Num1=Amount
Else
Num2=Amount
End If
Return Amount
End Function
Public Function GetDif()
Return Num1-Num2
End function
Right-click the second column to insert a third column with Outside Group-Right.
Then use the expressions below in the matrix.
=Code.GetAmount(Fields!Amount.Value,Fields!PeriodNumber.Value)
=code.GetAmount(Sum(Fields!Amount.Value),Fields!PeriodNumber.Value)
=Code.GetDif()
The report looks like below.
If you have any questions, please feel free to ask.

SQL Loader Constraints with Column Objects and Nested Tables

I am working on loading a Table that (god forbid) contains columns, column objects, and nested tables (which contains several depth of column objects). My question is does SQL Loader have a hidding undocumented feature where it states how the column objects must be grouped in refereneced to the nested tables within the loader file? I can load the various column objects, and nested tables fine right now, however, I am loading them all in strange and insane order. Can anyone answer this question? Thanks.

Column Group Hiding

Hi,
In the application, we have used a table (of type 'Advanced Table') and under that I require a column to get hidden in the table. When i navigate to see the columns through "Personalize" link corresponding to the table, I came to know the column i require to hide is represented in the form of column group. And under that column group, it has a sub-category of may columns present under it.
Will it be ok if i hide only the required column under that column group by setting the rendered property to 'false' or do i have to hide the entire column group itself ?
Suggestions needed....
With Thanks,
Thiyagarajan

Thanks All for your valuable responses...
In the same table, i am doing some calculations in the 'processFormRequest' method when the 'submit' button is clicked and the table has nearly more than 25 rows and it is listed as 10 rows per page.
Once the page gets loaded after the 'submit' button gets clicked, the page displays the table's last 10 records and not from the first 10. Is there any function can be used to point the records in the table in the ascending order instead of descending ?
With Thanks,
Thiyagarajan

SSRS Matrix not showing all the entry for a Column Groups

I created a Matrix in my SSRS report and for some reason if the COLUMN GROUP has more than one
entry it only shows the first one and not the second or consequent entries.
I opened a question in SO and here is the link:
http://stackoverflow.com/questions/23248421/how-to-add-column-in-a-ssrs-table-based-on-criteria
All help is appreciated.

Hi SiKni8,
According to your description, you have a matrix report. If a user has more than one start date and end date, you want to put all those start dates and end dates into one single row for this user. Right?
In Reporting Service, for all data fields textbox appearing at intersection of rows and columns, the matrix will use Sum aggregation function by default. If the data can’t be calculated by aggregation function, it will return the first one of records. This
is the reason why you only get the first start date and end date for each user. In your scenario, it is impossible to append more columns at the end of the matrix without setting column group. And we can never append columns dynamically based on the numbers
of the records. So for your requirement, we find a workaround which we think is the most related to the answer you want. We use custom code to get both StartDate and EndDate, then return them as string. After that we append those strings and put the whole
string into a cell. Your case has been tested in our local environment. Here are steps and screenshots for your reference:
Put the custom code below into your report:
Dim Num As String = ""
Dim tempstr As String = ""
Function AggregateString(Title as String, StartDate as String, EndDate as String)
If Title = Num Then
tempstr = tempstr + "(" +StartDate+" , "+EndDate+") "
Else
tempstr=""
Num = Title
tempstr =tempstr+"("+StartDate+" , "+EndDate+") "
End If
Return tempStr
End Function
In our sample report, we created a matrix based on your description. It looks like below:
In textbox next to [Title], put the expression below into it:
=runningvalue(Code.AggregateString(Fields!Title.Value,Fields!StartDate.Value,Fields!EndDate.Value),Last,"Title")
Ps: In our report, we set the type of date as string when creating table and dataset. If your date type is different, use Cstr() function and convert it into string.
Save and preview. The result looks like below:
