Delete multiple rows in a JTable ADF Swing.

hi guys,
Would anyone know tell me how do I delete multiple rows in a JTable ADF Swing?
JDeveloper.

Hi,
I would configure the table for multi row selection. Then get the selected row index, access the iterator in the PageDef file (through the panelBinding reference you have in ADF Swing) and then iterate over the selected row indexes, make an index to become the current row and call remove() on it

How to delete multiple rows from ADF table

How to delete multiple rows from ADF table

Hi,
best practices when deleting multiple rows is to do this on the business service, not the view layer for performance reasons. When you selected the rows to delete and press submit, then in a managed bean you access thetable instance (put a reference to a managed bean from the table "binding" property") and call getSeletedRowKeys. In JDeveloper 11g, ADF Faces returns the RowKeySet as a Set of List, where each list conatins the server side row key (e.g. oracle.jbo.Key) if you use ADF BC. Then you create a List (ArrayList) with this keys in it and call a method exposed on the business service (through a method activity in ADF) and pass the list as an argument. On the server side you then access the View Object that holds the data and find the row to delte by the keys in the list

How do i delete multiple rows in JTable

hello
how i delete multiple rows in JTable
when i selected multiple rows from the jtable and delete its give the error ArrayIndexOutOfBoundException
e.g.
int rows[]=jtable.getSelectedRows();
for(int i=0;i<rows.length;i++)
DefaultTableModel model=(DefaultTableModel)jtable.getModel();
model.removeRow(rows);
like this
please help me
meraj

You are trying to remove the rows an equal times to the amount of rows selected.
You should remove one row at a time:
model.removeRow(rows);
Change your code into this.
for(int i=0;i<rows.length;i++)
DefaultTableModel model=(DefaultTableModel)jtable.getModel();
model.removeRow(rows[i]);

It works always :

DCIteratorBinding iterator=binding.findIteratorBinding(iteratorName);
ViewObjectImpl vo=(ViewObjectImpl)iterator.getViewObject();
Vector vector=new Vector();
for(int i=0;i<vo.getRowCount();i++)
Row row=vo.getRowAtRangeIndex(i);
if(row.getAttribute("IsSelect")!=null)
if((Boolean)row.getAttribute("IsSelect")==true)
vector.add(row);
Row[] rows=new Row[vector.size()];
for(int i=0;i<vector.size();i++)
rows=(Row)vector.get(i);
if(rows.length>0)

Updating and deleting multiple rows

Hi!
I have a form on a table with report page where I can filter data through columns.
1. Is it possible to create a button that will delete all the filtered data?
2. Also, I would like to be able to update any column of the filtered dataset to a certain value (that needs to be input somehow). Is that possible?
So far I can only update or delete one row at a time, which isn't useful as I sometimes need to change 100 rows at a time with the same value or delete them.
When I use tabular form, I can't filter rows, but I can delete multiple rows...
Also if there are similar examples, could you please send me a link; I can't seem to find any.
I'm using Apex 4.2.2.
Best Regards,
Ivan

Best answered with Martin's example
http://www.talkapex.com/2009/01/apex-report-with-checkboxes-advanced.html
Depends how you filter your data. You could identify all your limiting variables, and reverse the where clause in a delete process.
As for point 2, you can define a button that redirects to the page, and you can defined all the item values you like using the Action link.
There is likely an example in the supplied package applications.

Deleting Multiple Rows From Multiple Tables As an APEX Process

Hi There,
I'm interesting in hearing best practice approaches for deleting multiple rows from multiple tables from a single button click in an APEX application. I'm using 3.0.1.008
On my APEX page I have a Select list displaying all the Payments made and a user can view individual payments by selecting a Payment from the Select List (individual items are displayed below using Text Field (Disabled, saves state) items with a source of Database Column).
A Payment is to be deleted by selecting a custom image (Delete Payments Button) displayed in a Vertical Images List on the same page. The Target is set as the same page and I gave the Request a name of DELETEPAY.
What I tried to implement was creating a Conditional Process On Submit - After Computations and Validations that has a source of a PL/SQL anonymous block as follows:
BEGIN
UPDATE tblDebitNotes d
SET d.Paid = 0
WHERE 1=1
AND d.DebitNoteID = :P7_DEBITNOTEID;
INSERT INTO tblDeletedPayments
( PaymentID,
DebitNoteID,
Amount,
Date_A,
SupplierRef,
Description
VALUES
( :P7_PAYMENTID,
:P7_DEBITNOTEID,
:P7_PAID,
SYSDATE,
:P7_SUPPLIERREF,
:P7_DESCRIPTION
DELETE FROM tblPayments
WHERE 1=1
AND PaymentID = :P7_PAYMENTID;
END;
The Condition Type used was Request = Expression 1 where Expression 1 had a value of DELETEPAY
However this process is not doing anything!! Any insights greatly appreciated.
Many thanks,
Gary.

...the "button" is using a page level Target,...
I'm not sure what that means. If the target is specified in the definition of a list item, then clicking on the image will simply redirect to that URL. You must cause the page to be submitted instead, perhaps by making the URL a reference to the javaScript doSubmit function that is part of the standard library shipped with Application Express. Take a look at a Standard Tab on a sample application and see how it submits the page using doSubmit() and emulate that.

Deleting multiple rows in a report ?

db11gxe , apex 4.0 , firefox 24 ,
how to delete multiple rows in a report at one time ?
thanks

Hi newbi_egy,
Here is a small demo with few steps that can be used in your scenario-
1) Below is the query of a report on emp table which has empno column with unique values-
SELECT APEX_ITEM.CHECKBOX(1,empno) " ", ename, job FROM emp ORDER by 1
2) A Delete button is created that submits the page.
3) An on-submit process is created with Process point On Submit - After Computation and Validations with condition that the below process runs when Delete button clicked.
BEGIN
FOR i in 1..APEX_APPLICATION.G_F01.count
LOOP
delete from emp where empno=APEX_APPLICATION.G_F01(i);
END LOOP;
END;
I hope this might help you.

Adding and Deleting Multiple Rows or Columns

How do you add or delete more than one row or column at a time.

Robby! wrote:
That's a great finding!
I just wrote a feedback requesting a shortcut like this.
It is a pity though that they desing it to work only if you select the header of the row/column. It should be enabled to work from within any cell in the table.
Who wrote such an error ?
These interesting shortcuts behave flawlessly even if the cursor was in D18 for instance.
(a) I never saw them in the delivered resources.
(b) they aren't responding to the OP's question which was about "Adding and Deleting Multiple Rows and Columns"

I´M DESPERATED.
I am able to delete row by row in my matrix, but ¿Could anyone post a sample to delete multiple rows?
I´ve been trying several ways but it doesn´t work.
My code is:
========================
Dim i As Long = oMatrix.GetNextSelectedRow
                If i > -1 Then
                    If oMatrix.IsRowSelected(i) = True Then
                        oMatrix.DeleteRow(i)

Deleting a row from a JTable using a custom TableModel

Before I waste any of your time I would like to go ahead and just say that I have searched through the forum using "delete row from Jtable" as the search keywords and while I have found very closely related issues, they have not solved my problem. I have found code postings by carmickr and his arguments as to why we should use DefaultTableModel instead of having created our own custom TableModel, and while I do agree, I just am not quite confident enough in applying it to my scenario. See I am reading from a file a bunch of Contractor objects and I am stuffing it into an arraylist which I am using in the following code posting to populate my TableModel which the JTable object in the gui then uses.
My problem is that everything works except when I delete and when I delete I understand that the index is changing because I just removed a row from the arraylist object. Suppose I have 33 rows displaying in the GUI. Now after I delete say row #23, the delete function works and dutifuly the row disappears from the table, but if I try to delete a row say...the last row, it does not work and throws me an IndexOutOfBoundsException which totally makes sense. My question is how do I go about fixing it? Do I have to do something with the setRowCount method?
Any help is appreciated.
Cheers,
Surya

Wow that was a very quick response. Thanks camickr. I am only trying to delete a single row. I do not know how to go about posting a test program for the code I have posted above because honestly the gui itself is 800 lines of code, and then the file reading class is quite funky in itself. I can maybe email you the entire Netbeans project including code so if you are using Netbeans 5 RC2 you can run the code and see for yourself, but that would not be considerate of me.
See I am trying to delete any row at any time...but only one at a time not multiple rows...so if a user decides to delete row 23 and then tries to delete the last row which happens to be row 33 in my case, my setup should be smart enough to still allow to delete the row.
