Validating user input in a datagrid column

Hi ,
I have 2 datagrid columns for users to enter data. I want to
restrict them only to enter numbers. I tried NumberValidator , that
does not work. Please help !! I am a newbee..
Thanks in advance..

We created an itemEditor for our dataColumn that was a
mx:TextInput. Then we used the textInput event to capture keys as
they are typed. You get a TextEvent from that which you can cancel
if it something you don't want the user entering. We used regexs
for are validation here. I'm not sure if this is the best way to
handle this sort of thing, but it worked.

Validating user input in VC using javascript

Hi All,
I'm exploring possible solutions for validating user input and reporting error messages back to the screen for users to correct their entries. It was mentioned in one of the threads that this can be done using javascript..
can the source code in VC be edited?? Can anyone give me pointers on how to achieve this and where to incorportate the javascript function for validation? Thanks!

Checking/Validating user input in a text field

How can I validate a user's input in a text field and require them to input it in the following format:
AAA 9999-999
(where A can be letters and 9 can be numbers)
Is there any documentation on how to validate user inputs in this manner?
Thanks!

Hi,
Create a validation PL/SQL process, select Function returning Error and use something similar to the example below.
I tested it but may be I missed something. I used field name P1_TEST.
DECLARE
v_number NUMBER;
v_error VARCHAR2(1000);
BEGIN
--check if you have numbers in positions 5-8 and 10-12
v_number:=SUBSTR(:P1_TEST,5,4);
v_number:=SUBSTR(:P1_TEST,10);
--check string length
IF LENGTH(:P1_TEST)!=12 THEN
RETURN 'String length must be 12 characters';
END IF;
--check if position 4 is empty
IF INSTR(SUBSTR(:P1_TEST,4,1),' ')=0 THEN
RETURN 'There should be a space between letters and numbers';
END IF;
--check if position 9 has "-"
IF INSTR(SUBSTR(:P1_TEST,9,1),'-')=0 THEN
RETURN 'There should be a dash between numbers';
END IF;
--check if positions 1-3 has letters
FOR i IN 1 .. 3 LOOP
SELECT ascii(substr(:P1_TEST, i, 1)) INTO v_number
FROM Dual;
IF v_number>=48 AND v_number<=59 THEN
RETURN 'Only letters are allowed in positions 1,2,3';
END IF;
END LOOP;
RETURN NULL;
EXCEPTION
WHEN OTHERS THEN
v_error:=SQLERRM;
IF INSTR(v_error, 'ORA-06502')>0 THEN
RETURN '...must be integers only';
ELSE
RETURN v_error;
END IF;
END;
I hope it will give you an idea on this type of validation.

Getting the user input from a JTables Columns

Hello
I am having real trouble with this could someone please help?
I have to columns on my JTable (first name , lastname).
How can I loop though each column like this?
the first column (first names), and get each row and add it to a String array?
for example if the user puts in 10 firstnames I want to add all 10 to a string array.
and for the second column, I want to add all the rows (last names ), to a arraylist. so if the user puts in 10 lastnames, I want to add them to the arraylist.
How can I do this?
thanks

how to add column dynamically based on from_date to to_date?

You cannot add columns dynamically. But you can define a maximum number of numbers and then hide unused columns in your form useing SET_ITEM_PROPERTY(..,VISIBLE, PROPERTY_FALSE);

Validation on a Datagrid Column

Hi,
I have a Datagrid with three columns, out of which two columns are editable. I want to apply string validator on one of the editable column. How can I do this?

You can have a custom ItemRenderer for that column which has a Validator built in. This has been covered in the docs. See this: http://livedocs.adobe.com/flex/201/html/wwhelp/wwhimpl/common/html/wwhelp.htm?context=Live Docs_Book_Parts&file=celleditor_073_17.html

Count the number of columns return in an user-input sql query

I need to do something like this
I let an user input a sql query and then execute it
assuming the sql query is always correct, it will return a Resultset
then a table will pop up to accomodate the number of columns the resultset will produce
i'm stuck at the part on how to check how many columns of data will be return in the resultset

     ResultSet rs = stmt.executeQuery("SELECT a, b, c FROM TABLE2");
     ResultSetMetaData rsmd = rs.getMetaData();
     int numberOfColumns = rsmd.getColumnCount();

Dynamically display/hide columns according to user inputs

Hi,
I need to display or hide columns in reports based on user input. ie. I have several prompts, if user doesn't input values, then the associated columns will not be displayed in the report. Is there a way to achieve this in BO XI R2. Greatly appreciated for your help.

Hi Andy,
You can't hide them totally, but you can get close using alerters.
Build an alerter (probably a formula one) that put the value ="" in the field.
Now the formula should test the userresponse for that column,
based on the contents of it (filled in --> false, otherwise --> true).
Apply the alerter to all cells of the column. It will empty completely when the prompt was not filled.
Just set the width of the column to automatic (best use the header cell only) and the minimum width on zero. It will shrink the width when empty, making it seem as if hidden.
Good luck,
Marianne

Displaying columns based on User Input

Hi,
I have a following requirement :
I have four columns in a report : Performance Indicator ,Target (XTD) , Actual (XTD),Indicator(Traffic Lights)
Based on the prompt, which contains column named as "Review Frequency" having values as 1. Monthly 2. Quaterly 3. Yearly.
When User select "Monthly" in pormpt I want to see MTD in Actual and Target column and Indicator depending on these columns.
When User select "Quaterly" in pormpt I want to see QTD in Actual and Target column and Indicator depending on these columns.
Can anybody tell me how can we achieve this?
I think I can achieve this with guided navigation but for that I have to create 3 reports.
Can anybody have any better idea to create just one report and based on user input I can show/hide columns in a single report?
This is mainly related to Balanced ScoreCard.
Thanks in advance
Regards,
Vikas

you have seperate columns for monthly, quarterly, and yearly, right?
In the prompt, save the "Review Frequency" as a Presentation Variable "abc";
In the request, you add actual (MTD) column, edit the formula, use something like:
CASE
WHEN @{abc}='Monthly' THEN "- SalesFacts"."actual (MTD)"
WHEN @{abc}='Quarterly' THEN "- SalesFacts"."actual (QTD)"
ELSE "- SalesFacts"."actual (YTD)"
END
then do the same thing for target column.

Validation in datagrid column

Hi,
Is there any way to validate datagrid column or cell.
Please help

Follow Tracy's advice, but also handle the itemEditEnd event.
In that event handler you can find if the data passed validation.
If it fails you can cancel the edit.
Look up itemEditEnd in the Flex 2 docs.

Checkbox in a datagrid column header not working properly

Hi,
I have rendered a checkbox in the header of a datagrid column
using headerRenderer property. That column also has all entries as
checkboxes. What I want to do is that on checking the header
checkbox, all checkboxes should get checked. Though I am able to do
this BUT the header checkbox remains uncheched in the whole
process! Whereas, if I remove this eventHandler from it, then the
header checkbox shows the correct state i.e., show checked on
checking & unchecked on unchecking!
Any input?
Thanks in advance,

hi many thanks for looking at my problem
what i am trying to do is show a column if the proc_id is greater than 2
it just looks a bit silly when a user configures the file (but not submitted it for loading)
the file cnt is null or zero - i had hoped not to show this - the proc_id is found from the report query !

User input in ALV Grid

Hello All,
Is it possible to have a user input in ALV grid. I know there can be editable columns/cells but suppose the application demands an input field to be placed in ALV Grid where the user will enter some value.
Could someone please suggest if this can be done.
Regards
Indrajit

Here's THE definitive way to do it.
This little proggy demonstrates the following.
1) Create a DYNAMIC FCAT for an internal table with USER defined fields (i.e non ddic) and colour some columns in the FCAT.
2) Create a DYNAMIC TABLE.
3) Define a subclass of CL_GUI_ALV_GRID so you can access some very useful protected methods and attributes - you can get original and changed table IN ROWS which is a lot easier sometimes than messing around with individual
cells.
4) Create extra buttons on the toolbar.
5) Define EVENT handlers including data change so you can get control when the user enters data. YOU DON'T NEED PAI anymore with event handlers.
6) Call methods in your subclass of CL_GUI_ALV_GRID (you can also call methods in CL_GUI_ALV_GRID by virtue of Inheritance) from methods in your event handler class.
7) Display an editable Grid.
This method will work for almost any conditions you need to use.
I'm sure this covers all the bases -- please reply if any queries.
Run the program, click on the EDIT button and enter your data. Press ENTER when done.
All you need to do is copy this code and create one empty screen (SE51) with a custom container called CCONTAINER1 with the following logic in it.
PROCESS BEFORE OUTPUT.
MODULE STATUS_0100.
PROCESS AFTER INPUT.
MODULE USER_COMMAND_0100.
(In the program you don't actually do anything in the PAI as the event handler takes care of this)
Now here's the program
PROGRAM zdynfieldcat.
class zcltest definition deferred. "For field symbol reference.

Refresh page but SAVE USER INPUT in tabular form WITHOUT UPDATE

Hi,
When there is a tabular form in the page and user refreshes it (in anyway) tabular form's elements are always computed with values from the table in db. Can we somehow save user input in fields so that after refreshing page user will see what he/she has typed but not submitted to db?
Regards,
Tom

Hello Andy,
Let me introduce you to the problem.
There is a tabular form based on a source table. User modifies the data and after he/she clicks Submit button the validation procedure is being run before MRU. If the result of validation is positive then MRU is run otherwise data should not be submitted to db and user should be informed about the result. Moreover, he/she should see the invalid data in fields. Not the correct one from db.
Is there any way to save a session state of these fields or of a whole tabular form? I cannot save the data in other table in db.
User cannot click 'Add row' several times in my app because after he clicks it once then the button disappears and appears again only when he/she clicks 'Submit' first (so after validation procedure).
Maybe there is some way to store fields' values in memory and then compute the form when page is loading again?
Imagine the situation that there are 100 rows in tabular form and user modifies it for one hour, clicks Submit, validation result is negative and his/her whole one hour work is lost, because the form has been refreshed according to what is stored in db. Such situation should never occur.
Regards,
Tom

Derive values based upon user input

Hello,
I recieved a request for a report.
When a user runs the report they are to be prompted for a fiscal year/period.
Based on the fiscal year/period that the user provides I have the following columns (in bold below are 2 examples that may make the description more clear).
1. Revenue for the Fiscal year Prior to the fiscal year of the user input value
2. Revenue for the Fiscal year/Period prior to the input Fiscal year/period
3. Revenue for the Year to date accumulation up to the prior fiscal year/period that the user input
4. Revenue for the Year to date accumulation up to the prior fiscal year (fiscal year rolls back first) and prior period (for period 01, it then rolls back the fiscal year 1 more year) that the user input
Example 1: If the user ran the query and they provided the value 05/2007, then the values that need to be obtained would be:
1. Revenue for 2006
2. Revenue for 04/2007
3. Revenue for 01/2007 to 04/2007
4. Revenue for 01/2006 to 04/2006
Example 2: If the user ran the query and they provided the value 01/2008, then the values that need to be obtained would be:
1. Revenue for 2007
2. Revenue for 12/2007
3. Revenue for 01/2007 to 12/2007
4. Revenue for 01/2006 to 12/2006
Please help me with determining how to obtain the user input value, and then how to derive the time periods for the columns based upon that value.
Thanks,
Nick

Hello,
See my example.. I am reading the value from Keydate Variable
WHEN ZVND01
        READ TABLE i_t_var_range INTO w_var_range WITH KEY vnam = 'Keydate'.
         IF SY-SUBRC = 0.
          CLEAR l_s_range.
          l_date = w_var_range-low.
          concatenate l_date(6) '01' into l_first_date.
          CALL FUNCTION 'SLS_MISC_GET_LAST_DAY_OF_MONTH'
          EXPORTING
                    day_in = l_date
          IMPORTING
                     last_day_of_month = l_last_date
          EXCEPTIONS
                    day_in_not_valid = 1
                    OTHERS = 2.
          IF sy-subrc EQ 0.
            l_s_range-low = l_first_date.
            l_s_range-high = l_last_date.
            l_s_range-sign = k_sign_inclusive.
            l_s_range-opt = k_option_between.
            APPEND l_s_range TO e_t_range.
          ENDIF.
Hope this example helps..
