Delete multiple rows in jtable

here's what i want to do
let user select the rows themselves and then when they press delete button, the rows that they select are removed
however, I do not have any idea on how to go about doing that though, like how do I get the selection value (sometimes it may be one whole chunk, sometimes it might be at different places altogether)

but the problem comes in after sorting the row;Are we supposed to be mind readers? How where we supposed to guess that the problem was related to sorting based on your original question. Learn to ask a proper question so you don't waste our time.
Anyway you still haven't given us enough information to help you.
Are you using the sorting feature of JDK6, in which case the API has methods that allow you to convert the "view" row to the "model" row. So I suggest you read the API.

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]);

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
Example 134 here: http://blogs.oracle.com/smuenchadf/examples/#134 provides you with the code

It works always :
DCBindingContainer binding=(DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
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)
for(int i=0;i<rows.length;i++)
rows[i].remove();

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

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.

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.

These interesting shortcuts behave flawlessly even if the cursor was in D18 for instance.

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

Deleting a row from JTable

I am trying to delete a row from a JTable whenever the button on the last column is pressed. I know to do this, I can use the removeRow(int) method of the tableModel. But the odd thing is when I try to get a handle to the TableModel from the JTable to use that function, i.e. table.getModel().removeRow(int) it doesn't work. But if I explicitly pass in the tableModel into my class it does work. Here's the code below:

          // table.getModel().removeRow(selectedRow);
}Take a look at the actionPerfformed method. One way of doing it works, one doesn't. Just trying to understand why me getting a handle to the tableModel through the table doesn't work.

It gives me a run-time error Well then your question should be "why do I get this run-time error" and then you would quote the error. Be more descriptive. "It doesn't work" is not descriptive.
table.getModel().removeRow(selectedRow);I don't use JDK1.5 either. But if you are saying that the above line compiles cleanly with JDK1.5 (because of the auto-boxing feature, or whatever its called), then I see no reason why the code wouldn't work since it recognizes the class as a DefaultTableModel.
Presumably you commented out the other line so you don't try to delete the row twice. Otherwise you might be getting a indexing error.

Delete multiple rows from table/list control

Hi,
I want to have a table control in which a user can enter different entries, like this:
My program would read each entry at a time and do something.
However, I would like to give the user ability to delete multiple entries at once, like in an Excel spreadsheet - that is, the user selects multiple rows and presses "Delete" key and those entries get deleted. The Labview table does not allow this it seems - I can only delete one entry at a time - or I have to right-click and select Data Operations->Cut Data, which is awkward.
Is there a control better suited to what I want to do? I tried a Llist control, but it behaves in the same manner.
Thanks in advance!
Solved!
Go to Solution.

You could write your own routine. Use an Event Structure with a Key Down event. If the delete key was pressed and the table has focus delete the elements that are selected.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Problem of deletion of rows in jtable, table refreshing too

Hi,
I have a table with empty rows in the beginning with some custom properties( columns have fixed width...), later user would be adding to the rows to this table and can delete, I've a problem while deleting the rows from table,
When a selected row is deleted the model is also deleting the data but the table(view) is not refreshed.
Actually i'm selecting a cell of a row, then hitting the delete button.
So the model is deleting the information, but i'm not able to c the fresh data in table( especially when the last cell of last row is selectd and hit the delete button, i am getting lots of exception)

Hi,
I've got the solution for it. As when the cursor is in cell of
a row and hit the delete button, the data in that cell is not saved,
So i'm trying to save the data first into the model then firing the action event by doing this ..
jButton2.addActionListener( new ActionListener(){
public void actionPerformed(ActionEvent actionEvent){
// If a button press is the trigger to leave a JTable cell and save the data in model
if(jTable1.isEditing() ){
String text=((javax.swing.text.JTextComponent)jTable1.getEditorComponent()).getText();
jTable1.setValueAt(text,jTable1.getSelectedRow(),jTable1.getSelectedColumn()) ;
jTable1.getCellEditor().cancelCellEditing();
// HERE DO THE DELETE ROW OPERATION
<yaman/>

Delete multiple rows in jtable
