How to diplay table row dynamically by button click

Hi All,
I had a table with with visible row count '3', i want to display dynamic row by a button click, mean a 4 th row need to be added to the table with same like row '3'.
please help me ..
Thanks,
Raj.

Hi Raju,
while click the Add Button,
Get the all the Rows from the Table and Put it in to one internal table . after that append the one empty record to that internal table. then again bind to that node.
Like following code.
DATA lo_nd_sales TYPE REF TO if_wd_context_node.
DATA lo_el_sales TYPE REF TO if_wd_context_element.
DATA ls_sales TYPE wd_this->element_sales.
DATA lt_sales TYPE wd_this->elements_sales.
navigate from <CONTEXT> to <SALES> via lead selection
lo_nd_sales = wd_context->get_child_node( name = wd_this->wdctx_sales ).
get element via lead selection
lo_el_sales = lo_nd_sales->get_element( ).
CALL METHOD lo_nd_sales->get_static_attributes_table
EXPORTING
   from   = 1
   to     = 2147483647
    IMPORTING
      table = lt_sales
IF lt_sales IS NOT INITIAL.
    CLEAR ls_sales.
    APPEND ls_sales TO lt_sales.
    lo_nd_sales->bind_table( lt_sales ).
ENDIF.

Vijay.

How to create editable tablecells for a single table row dynamically?

Hi
How to make the cell of a tablerow editable based on flag in backing list object bound to row? I can't decide the editable property while creating table columns. So i can't use setCellFactory() during creation. However setCellFactory() makes all cells in table column editable.How to make non-editable table row cell editable and vice-versa based on flag?

hi
good
if you want to create two different view for a same table than you cant give the same name for the same view,otherwise it would allow you to create the view.Try out with different view name as well as the function group name,i hope this ll work.

How to create table columns dynamically ?

Hi All,
I am working on an SSRS report that will show sales in the past 5 years. If the user selected to view sales of past 3 years he will only see 3 columns. so How can I create table columns dynamically at run time and how can I make sure that their dimensions
will adjust to fit the report page size.

Hi Developer life,
According to your description that you want to dynamically increase and decrease the numbers of the columns in the table, right?
As Jason A Long mentioned that we can use the matrix to do this and put the year field in the column group, amount fields(Numric values) in the details, add an filter to filter the data base on this column group, but if
the data in the DB not suitable to add to the matrix directly, you can use the unpivot function to turn the column name of year to a single row and then you can add it in the column group.
If there are too many columns in the column group, it will fit the page size automatically and display the extra columns in the next page.

If your still have any problem, please try to provide us more details information, such as the data structure in the DB and the table structure you are currently designing.
Any question, please feel free to let me know.

How to add another row dynamically in Adobe Forms ?

Hello All,
Can someone advise on how am I able to add another row to my table upon the click of a button in Adobe Form ?
Based on some sample PDFs that I downloaded from the net as reference, it seems that all I need to do is add the statment "_Car.addInstance(1)" in the script editor that will trigger upon a clicking of a button where Car is a subform that is of Type : Flow Content and Direction : Table Row set.
Any suggestion/advise will be greatly appreciated.
from
Kwok Wei

Hello Kwok Wei,
in NW 2004s, this will be possible on the client using a special forms library object provided by Adobe.
Be aware, though, that while you are able to add any number of additional lines on the PDF, the original Web Dynpro context is not aware of these actions. This means that your application needs to create the corresponding new nodes in the context before the data contained in these nodes can be submitted back to the application.

How to use table name dynamically in report procedure

Hello every body
I want to use table name dynamically means at runtime i want to pass table name.
I can do this by lexical parameter in main query.
But my problem is that i want to crate new format trigger or new function that use 1 cursor in which that lexical parameter : table name is used.
so how to do that?
i can not use that lexical parameter it is giving error.
please help me how to do that.

Call a database function which you pass the lexical parameter. Then in the database function you use dynamic sql or the execute immediate option to build the SQL string.
Return the information from this function to build your business logic on in your format trigger.

How to retrieve table rows data and add into DB

Hi All,
I'm a beginner in JAVAFX, I have developed a table and adding the data into the table in multiple rows. on button click I would like these rows to be added into DB.
Please could anyone help on this. I'm copy the code for reference.
CODE:
import javafx.ext.swing.SwingComponent;
import javax.swing.event.ListSelectionEvent;
import javax.swing.event.ListSelectionListener;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;
package class TableColumn{
public var text: String;
package class TableCell{
public var text: String;
public var id;
public var str:String;
public var str1:String[];
public var num:Number;
package class TableRow{
public var cells: TableCell[];
package class SwingTable extends SwingComponent{
var table: JTable;
var model:DefaultTableModel;
public var selection: Integer;
public var columns: TableColumn[] on replace{
model = new DefaultTableModel(for(column in columns) column.text, 0);
table.setModel(model);
public var rows: TableRow[] on replace oldvalue[lo..hi] = newVals{
for(index in [hi..lo step -1]){
model.removeRow(index);
for(row in newVals){
model.addRow(for(cell in row.cells) cell.text);
public override function createJComponent(){
table = new JTable();
model = table.getModel() as DefaultTableModel;
var selectionModel = table.getSelectionModel();
selectionModel.addListSelectionListener(
ListSelectionListener{
public override function valueChanged(e: ListSelectionEvent ) {
selection = table.getSelectedRow();
return new JScrollPane(table);
}

Instead of using a combo box, using a text ring makes it much easier to disable items in the list. Here is a vi that will do what you want. Also you can delete the last element in the table and make it enabled in the text ring for selecting again.

Smartforms how to print Table rows on to the next page automatically

if this question is answered pls point to the the link
SMART forms:
layout : Half of my A4 page is filled with templates, a small portion is footer, the middle portion is Table.
Note: i have set the condition for the footer as (tick the check box) "only after end of main window"
Output:
                   the template is displayed the table is populated on the first page, no footer on 1st page,
                on page 2 the table rows are printed (table rows were a lot) and finally footer got printed every thing as per normal
what i want is:
                 instead of the table lines printed in the middle of page 2 (bcz my main window table is in the middle, top is templates)
                 i want the table lines (after filling the main window table lines in the 1st page) to continue to print from the
                 top of the page on page 2 and immediately after the table rows finish. footer must be printed....
what should i be doing to get this output

dear bob,
yes i have done that already as u said, when i do it......
i created a new page (next page) directed first page to next page
on the next page my layout is like below
removed all the templates dragged the main window to the top of the page......
when i check the result, there is an empty line as the first line in the table (2nd page)
and also the footer (again a template) on the first page, which is ticked as ( print after end of main window) is NOT displaying.

Hi,
1. Create a context attribute name visible1 of type type com.sap.ide.webdynpro.uielementdefinitions.Visibility(using brose button in the type property of context)
2. Bind this context to all tha elements of that you want to make visible when radio button 1 is clicked to their visibility property.
3. Create a context attribute name visible2 of type com.sap.ide.webdynpro.uielementdefinitions.Visibility(using brose button in the type property of context)
4. Bind this context to all tha elements of that you want to make visible when radio button 2 is clicked to their visibility property.
5. Create actions for both radio button1 say action1 and for radio button2 say action2.
6. In action1 write this line of code
wdContext.currentContextElement.setVisible1(WDVisibility.VISIBLE);
wdContext.currentContextElement.setVisible2(WDVisibility.BLANK);
7. In action2 write this line of code
wdContext.currentContextElement.setVisible2(WDVisibility.VISIBLE);
wdContext.currentContextElement.setVisible1(WDVisibility.BLANK);

You probably need to rethink your design. Where are these child classes going? What is using or consuming them? I agree with the message above about a button instantiating a parent field variable to one child or the other depending on which button is pressed.

How to open multiple report windows on button click without losing session?

Hi,
JDev : 11.1.1.2.0
I am trying to open multiple discoverer plus report windows using my ADF application.
My requirement is that user has to select multiple reports from the screen and by clicking on submit button all the reports should be opened in different windows.
1) Below link provided me the the first solution but I can't go with it because my page is jsff and in jsff it doesn't support form tag.
http://andrejusb.blogspot.com/2007/07/opening-report-window-in-adf-faces.html
2) RichGoButton also provide targetFrame property but there is not action property in it so I can't call backing bean method with RichGoButton
3) I have tried to open report windows using javascript window.open with ExtendedRenderKitService but on discoverer side it giving error message that Discoverer Plus cannot attach same session to multiple request.
4) I have created one jsp page in the same folder where my jsff is kept in my ADF application and on submit button click I have launch this jsp page using afConetxt.launchDialog and in jsp scriplet I have written response.sendRedirect to report url but here all report are getting open properly to seperate windwos but my ADF application session is getting timeout so after clicking on submit button it will automatically goes to login page it cann't stay with the current page.
Hoe you have understnad my problem and please provide me if you know any other solution aprart from above mentioned 4 solutions

How to popup a menu when rigth button clicked?

Hi, i have a mouse listener on a Jtree, it is working fine and now i want that when the user clicks in the right button of the mouse, a popUp menu appears with diferent options depending on the type of node....i only need to know how do make the menu to appear...

I have had this same problem. For me it always occurs on Mandrake (I've only tried 8.0 and 8.1), but I have never had it occur on other Linux distributions such as Red Hat or Debian.
Quick caveat: Although Sun says that this is not a
bug I have installed Java on 5 different computers
with various versions of Mandrake Linux (7.1, 8.0, and
8.1) In these installations a left click (the main
button click) will return a mouse event with a button
mask of BUTTON1_MASK + BUTTON3_MASK instead of simply
BUTTON1_MASK. This makes your popup window appear on
every mouse click instead of just right button click.
The solution (until this bug is fixed) is to see if
the int returned from the getModifiers() method on
mouse event == BUTTON1_MASK + BUTTON3_MASK and if it
does then DONT popup the window.
Oddly enough, I've had other people test this and they
tell me that the mouse events return the proper button
mask but every time I've tested it I get this bug.
Just a FYI. If you see that behavior then this is how
to fix it.
